y is directly proportional to √x.
y is 80 when x=100.
Find a formula linking x and y.

Answers

Answer:

Example 1: Y is directly proportional to x. When x = 5, y = 8. What does y equal when x = 9?

First, we set up our general equation. Because y is directly proportional to x, we have:

y = cx

where c is the constant of proportionality. In other words, when x goes up, y goes up, and when x goes down, y goes down.

The next thing we do is plug our values for x and y into the equation so we can solve for c:

8 = (c)(5)

Solving for c, we get c = 8/5 = 1.6 and we plug this into our equation:

y = 1.6x

Now, we can plug x = 9 into the equation to find out what y equals:

y = (1.6)(9)

y = 14.4

So, our answer is 14.4

Example 2: Y is directly proportional to the square of x. When x = 2, y = 32. What does y equal when x = 5?

This time, our general equation is slightly more complicated because x is squared:

y = cx2

Like before, we solve for our constant:

32 = (c)(22)

32 = (c)(4)

We get c = 8:

y = 8x2

Solving for y when x = 5, we get y = (8)(52) = (8)(25) = 200

Example 3: Y is inversely proportional to x. When x = 2, y = 8. What does y equal when x = 24?

This time, because y is inversely proportional to x, our general equation is different:

xy = c

so when x goes up, y goes down, and vise versa. But, other than that, we solve these kinds of problems the same way as direct proportion problems. Solving for the constant, we get:

(2)(8) = c

So c = 16 and our equation is now:

xy = 16

Solving for y when x = 24 we get y = 16/24 = 2/3

Example 4: Y is inversely proportional to the square root of x. When x = 36, y = 2. What does y equal when x = 64?

As before, we set up our equation:

eq001

Since the square root of 36 is 6, it is easy to solve for c:

(6)(2) = c

We get c = 12 and our equation is now:

eq002

Solving for y when x = 64 we get 8y = 12 or y = 12/8 = 1.5 because the square root of 64 is 8.

Answer:

y = 8

Step-by-step explanation:

because y is directly proportional to .√x

=> y = a√x

but when x = 100, y = 80

=> 80 = 10a

=> a = 8

=> y = 8√x

The standard error of the mean for a sample of size 153 is 25. in order to cut the standard error of the mean in half (to 12.5) we must select a sample size of?

Answers

In order to cut the standard error of the mean in half (to 12.5), you must select a sample size of 612.

To find the new sample size required to cut the standard error of the mean in half, you can use the following formula:

New Standard Error = (Old Standard Error) / √(New Sample Size / Old Sample Size)

We know the old standard error (25) and want to find the new standard error (12.5). So, we can rewrite the formula as:

12.5 = 25 / √(New Sample Size / 153)

First, divide both sides of the equation by 25:

0.5 = 1 / √(New Sample Size / 153)

Next, square both sides of the equation:

0.25 = 1 / (New Sample Size / 153)

Now, take the reciprocal of both sides:

4 = New Sample Size / 153

Finally, multiply both sides by 153 to find the new sample size:

New Sample Size = 4 * 153

New Sample Size = 612

Details Money is transferred continuously into an account at the constant rate of $230,000 per year. The account earns interest at the annual rate of 3.7% compounded continuously. How much will be in the account at the end of 10 years? Round to the nearest dollar

Answers

Rounding off the answer to the nearest dollar, the amount in the account at the end of 10 years is $377,453.

Given that money is transferred continuously into an account at the constant rate of $230,000 per year, and the account earns interest at the annual rate of 3.7% compounded continuously.

We are to find how much will be in the account at the end of 10 years.

To solve this question, we can use the formula for continuous compound interest, which is given as;

A = Pert,

where

A = the balance in the account at the end of the investment period

P = the principal amount (the initial amount invested)

exp = is Euler’s constant ≈ 2.71828

r = the annual interest rate expressed as a decimal

t = the time the money is invested

Using the formula above to solve the question;

P = $230,000r = 0.037

t = 10 years

A = Pert

A = $230000 * e(0.037*10)A = $377,453.06

Rounding off the answer to the nearest dollar, the amount in the account at the end of 10 years is $377,453.

The rate at which the machine crushes dry fruit is option (D) 4 1/3 kilograms per minute.

To find the rate at which the machine crushes dry fruit, we need to divide the amount of fruit crushed by the time taken. We can convert the mixed number of 3 1/4 kilograms to an improper fraction as follows

3 1/4 = (3 x 4 + 1)/4 = 13/4

So the rate at which the machine crushes dry fruit is

rate = amount of fruit crushed / time taken

= (13/4) / (3/4)

= 13/4 x 4/3

= 13/3

Convert to mixed fraction

= 4 1/3

Answer:

Area of the gym floor = 100.8 square meters

Step-by-step explanation:

Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap

Area of rectangle A = 105 square meters

Area of rectangle B = 8.4 square meters

Area of the overlap = \(\frac{3}{25}\times (\text{Area of rectangle A})\)

                                = \(\frac{3}{25}\times 105\)

                                = 12.6 square meters

Area of the gym floor = 105 + 8.4 - 12.6

Molly placed $220. 00 in a savings account. This savings account earns 4. 2% interest per
year. She did not add or take out any money from this account. How much money did
she earn in interest at the end of six years?

Answers

Molly earned $282.37 - $220.00 = $62.37 in interest at the end of six years.

What is compound interest?

The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.

To solve this problem, we can use the formula for compound interest:

\(A = P(1 + r/n)^(nt) \)

We are given that Molly placed $220.00 in a savings account with an annual interest rate of 4.2%. We are also told that she did not add or take out any money from the account, so the principal remains $220.00. Since we are not given how many times per year the interest is compounded, we will assume it is compounded annually (n = 1).

After 6 years, the formula becomes:

\(A = 220(1 + 0.042/1)^{(1*6)}A = 220(1.042)^6\)

A = 220(1.2835)

A = $282.37

Therefore, Molly earned $282.37 - $220.00 = $62.37 in interest at the end of six years.

Answers

By the principle of mathematical induction, we have shown that P(n) is true for n ≥ 1.

To the proof the mathematical induction for p(n) is true for n≥1 the following steps we have to follow;

Step 1: Base case (n = 1)

We need to prove that P(1) is true:

1 + 4 = 3/4(1 + 1/(-1))

5 = 3/4(2 - 1)

5 = 3/4(1)

5 = 5

Step 2: Inductive hypothesis

Assume that P(k) is true for some positive integer k. That is:

1 + 4 + (4/2) + ... + (4/k) = 3/4(k + 1) - 1

Step 3: Inductive step

We need to prove that P(k + 1) is true using the inductive hypothesis:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = 3/4((k + 1) + 1) - 1

Adding (4/(k + 1)) to both sides of the inductive hypothesis:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = 3/4(k + 1) - 1 + (4/(k + 1))

Simplifying the right-hand side:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = 3/4(k + 1) - 1 + 4/(k + 1)

Combining like terms:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = (3(k + 1) - 4 + 4)/(4(k + 1))

Simplifying further:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = (3k + 3)/(4(k + 1))

Common denominator on the right-hand side:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = (3k + 3)/(4k + 4)

Simplifying the numerator:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = 3(k + 1)/(4(k + 1))

Canceling out the common factors:

1 + 4 + (4/2) + ... + (4/k) + (4/(k + 1)) = 3/4(k + 1)

Therefore, P(k + 1) is true.

Translate K to L and reflect across the line containing HJ.

Answers

Answer:B

Step-by-step explanation:

Transformation involves changing the position of a shape.

To map ΔHJK to ΔLMN, we (b) Translate K to N and reflect across the line containing JK.

ΔHJK and ΔLMN are similar triangles; this means that the following sides are corresponding:

HJ and LMHK and LNJK and MN

The first translation would be to translate corresponding sides K to N.

Then triangle HJK must be translated across a line that contains point K (i.e. either line JK or line HK)

By comparing the options, the true statement is:

(b) Translate K to N and reflect across the line containing JK.

what is the domain of validity for csc 0=1/sin 0
a. all real numbers
b. all real numbers except odd multiples of pi/2
c. all real numbers except even multiples of pi/2
d. all real numbers except multiples of pi

Answers

The correct answer is (b) all real numbers except odd multiples of π/2. The domain of validity for cscθ (cosecant) is restricted because cosecant is undefined when the sine of an angle is zero.

In the trigonometric identity cscθ = 1/sinθ, the denominator sinθ becomes zero at odd multiples of π/2 (such as π/2, 3π/2, 5π/2, etc.), resulting in a division by zero error. Therefore, the cosecant function is not defined for these values of θ.

For all other real numbers θ, the sine function is non-zero and well-defined, allowing us to calculate the reciprocal of the sine and determine the value of the cosecant. Hence, the domain of validity for cscθ is all real numbers except odd multiples of π/2, as stated in option (b).

It's important to note that in trigonometry, the domain of validity is determined by avoiding any values that would lead to undefined expressions or division by zero errors.

Final answer:

The domain of validity for csc θ = 1/sin θ is all real numbers except multiples of π, because at these points the sine function equals zero, and division by zero is undefined.

Explanation:

In mathematics, the cosecant function (csc), is defined as the reciprocal of the sine function, or 1/sinθ. The domain of a function are all the possible input values that will yield real numbers (output). For the csc function, its domain includes all real numbers except where the denominator is zero because division by zero is undefined.

In the unit circle context, sine equals zero at 0, π, 2π, ..., and the negative counterparts. Basically, these are the multiples of π. Thus, for the csc function, the domain is all real numbers except multiples of π, which matches option d in your choices.

The domain of validity for csc θ = 1/sin θ is all real numbers except multiples of π.

Sean is three more than twice as old as brotherIf ages total 15equation describes this situation represents Sean's brother's age ?

Answers

Sean's age is 4 years and his brother's age is 11 years.  

Linear Equations in Two Variables: It is an equation written in the form ax+by +c=0. a, b, and c are real values, whereas x and y are variables. We can say that a and b are not equal to zero. Linear equations are solved when the same number is added to both sides, as well as when both sides are multiplied and divided by the same amount. Linear equations with two variables are denoted by x and y.

Let Sean's age be y years.

Let Sean's brother's age be x years.

Sean is three more than twice as old as brother.

∴ y = 2x + 3      -- (1)

Also, the total of their ages is 15.

∴ x+y = 15

⇒ y = 15 -x     -- (2)

Substitute y from equation (2) in equation (1)

⇒ 2x + 3 = 15 - x

⇒ 3x = 12

∴ x = 4

Put x in equation (2)

⇒ y = 15- 4

∴ y = 11

Thus, Sean's age is 4 years and his brother's age is 11 years.

When you exercise, your cells produce more carbon dioxide. select two organ systems and explain how they can help maintain homeostasis after exercise.

Answers

Two organ systems that help maintain homeostasis after exercise are the respiratory system and the cardiovascular system.

1. Respiratory System:

During exercise, the increased activity of muscles leads to an increased demand for oxygen, and as a result, the cells produce more carbon dioxide (CO2) as a byproduct of cellular respiration. The respiratory system plays a vital role in maintaining homeostasis by regulating the levels of oxygen and carbon dioxide in the body.

After exercise, the respiratory system responds by increasing the rate and depth of breathing. This elevated ventilation allows for a greater intake of oxygen from the inhaled air. The oxygen-rich air enters the lungs, where it diffuses across the thin walls of the alveoli and into the bloodstream. Simultaneously, the increased ventilation facilitates the removal of carbon dioxide from the bloodstream into the alveoli, ready to be exhaled.

By adjusting the rate and depth of breathing, the respiratory system helps restore homeostasis by replenishing oxygen levels and eliminating excess carbon dioxide. This ensures that the body's cells receive the necessary oxygen for energy production while preventing the buildup of carbon dioxide, which can be detrimental if allowed to accumulate.

2. Cardiovascular System:

The cardiovascular system, composed of the heart, blood vessels, and blood, works in conjunction with the respiratory system to maintain homeostasis after exercise. Its primary function is to deliver oxygen and nutrients to the tissues while removing waste products, including carbon dioxide.

During exercise, the cardiovascular system responds to the increased demand for oxygen and the accumulation of carbon dioxide. The heart rate increases, leading to a higher cardiac output. The cardiac output is the amount of blood pumped by the heart per minute, and it increases to meet the heightened oxygen requirements of the active muscles.

As the heart pumps more vigorously, blood flow to the muscles is enhanced. This allows for the delivery of oxygen and nutrients to the working tissues, promoting their optimal function. Simultaneously, the increased blood flow facilitates the removal of carbon dioxide produced during exercise.

The blood vessels also play a role in maintaining homeostasis after exercise. They undergo vasodilation, which means the blood vessels widen to accommodate the increased blood flow to the muscles. This vasodilation helps dissipate heat generated during exercise and allows for efficient oxygen and nutrient delivery to the tissues.

Together, the respiratory system and the cardiovascular system work synergistically to maintain homeostasis after exercise. The respiratory system ensures an adequate supply of oxygen and the elimination of excess carbon dioxide, while the cardiovascular system delivers oxygen and nutrients to the tissues while removing waste products. This coordinated effort helps restore the body's internal balance and supports efficient cellular function.

Is the discriminant of g positive, zero, or negative?


(will mark the brainliest)

Answers

The discriminant of g can be positive, zero, or negative, depending on the specific values of the quadratic equation in g.

The discriminant is a term used in the quadratic formula to determine the nature of the roots of a quadratic equation. It is calculated as b^2 - 4ac, where a, b, and c are the coefficients of the quadratic equation in the form ax^2 + bx + c = 0.

If the discriminant is positive, it means that the quadratic equation has two distinct real roots. This occurs when b^2 - 4ac > 0.

If the discriminant is zero, it means that the quadratic equation has one real root with multiplicity. This occurs when b^2 - 4ac = 0.

If the discriminant is negative, it means that the quadratic equation has two complex conjugate roots. This occurs when b^2 - 4ac < 0.

To determine whether the discriminant of g is positive, zero, or negative, we would need to know the specific coefficients of the quadratic equation in g. Without that information, we cannot provide a definitive answer.
