Find the slope of the line graphed below.

Answers

Answer 1

Answer:

the slope is -3/2

Step-by-step explanation:

to find the slope, one way is to do rise over run. you cound how many units up you need to go to get to the level of the other point (3 units), and "run" is how many units horizontally you need to go to reach the other point (-2 units).

another way to solve this (this one is more commonly used) is the formula (y₂ - y₁) / (x₂ - x₁). the first point (₁) is (3, -2) and the second point (₂) is (1, 1). so you can fill in the y's and x's to get (1 - ⁻2) / (1 - 3) which gives you the answer of 3/-2 or -3/2.

hope this helps!

5/6 is the probability that the number landed on an odd or is greater than 4

Probability concept

Probability is defined as the likelihood or chance that an event will occur.

If a number cube is rolled, the sample space will be:

(S) = {1, 2, 3, 4, 5, 6}

n(S) = 67

If it lands on a odd number, the number of events will be:

(E) = {1, 3, 5}

n(E) = 3

If it lands on a number greater than 4 the number of events will be:

(E) = {5, 6}

n(E) = 2

Pr(even or greater then 4) = 3/6 + 2/6

Pr(even or greater then 4) = 5/6

The probability that the number landed on an odd or is greater than 4 is 5/6

Use the applet to give the square a side length of 1.3 cm. At this moment, what is the measure of the perimeter of the square (in cm) in units of the side length of the square (in cm)

Answers

Answer:

Perimeter, P = 5.2 cm

Step-by-step explanation:

Perimeter is the sum of all the sides.

All sides of a square is equal. Here, the side of a square is 1.3 cm.

The perimeter of a square is given by :

P = 4 × side

It means,

P = 4 (1.3 cm)

P = 5.2 cm

Hence, the perimeter of the square is 5.2 cm.

Mr. Smith and Mr. Stein were driving to a business meeting 140 miles from their office. Mr. Smith drove the first
miles, then Mr. Stein drove the rest of the way.

Write an algebraic expression for how many miles Mr. Stein drove.

Answers

The distance that Mr. Stein drove can be represented by the expression: $140 - x$

What is an algebraic expression?

A mathematical phrase made up of one or more variables, constants, and arithmetic operations like addition, subtraction, multiplication, and division is known as an algebraic expression. Exponentiation and other mathematical operators could also be present.

Let's assume that Mr. Smith drove "x" miles before Mr. Stein took over the driving.

Then, the total distance they traveled is 140 miles.

So, the distance that Mr. Stein drove can be represented by the expression:

140 - x

Therefore, This is because if Mr. Smith drove "x" miles, then the remaining distance that needed to be covered by Mr. Stein would be the difference between the total distance of 140 miles and the distance already driven by Mr. Smith.

What is inverse of a function?

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1.

In this problem, the function given is f(x) = x + 4;

We can find the inverse of the function as;

y = x + 4;

Answers

Answer:

x = -232

Step-by-step explanation:

Ronu's present age is "x “years and her sister Shaani's present age is twice of Ronu's age.

(a) Ronu's present age = x years

(b) Ronu's age after 2 years = (x+2) years

(d) Shaani's age after 2 years = (2x+2) years

Let x should be added to 100 to get -132.

x+100 = -132

x = -100-132

x = -232

Hence, -232 must be added to 100 to get -132.

From the question, we have the following parameters that can be used in our computation:

Population function, P(t)= 15е⁻⁰.⁰¹²⁺

Also from the question, we have

The variable t represents the number of years since 2020

This means that the value of t in 2030 is

t = 2030 - 2020

t = 10

P(10)= 15е⁻⁰.⁰¹² ˣ ¹⁰

Evaluate the above products

P(10)= 15е⁻⁰.¹²

Evaluate the exponents

P(10)= 13.30

Approximate the above expression

The quadratic function that models the vertical motion is h(t) = -16t² + 96t + 77

The maximum height is 221 ft

Writing a quadratic function and determining the maximum height

From the question, we are to write a quadratic function to model the vertical motion

h(t) = -16t² + v₀t + h₀

From the given information,

Initial velocity is 96 ft/s

That is, v₀ = 96 ft/s

and

Initial height is 77 ft

That is, h₀ = 77 ft

Thus,

The function becomes

h(t) = -16t² + 96t + 77

To determine the maximum height, we will compare the equation to the general form of a quadratic function

y = ax² + bx + c

t = -b/2a

Where t is the time taken to reach maximum height

By comparing with h(t) = -16t² + 96t + 77

a = -16 and b 96

Thus,

t = -96 / (2 × -16)

t = -96 / -32

t = 3 seconds

Now, we will determine the height at 3 seconds

h(t) = -16t² + 96t + 77

h(3) = -16(3)² + 96(3) + 77

h(3) = -16 × 9 + 288 + 77

h(3) = -144 + 288 + 77

h(3) = 221 ft

Hence, the maximum height is 221 ft

∫ (log(1 + x ^ 2))/((x + 1) ^ 2) dx

Answers

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

We have,

To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.

Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:

∫ (log(1 + (u-1)²) / u²) du.

Expanding the numerator, we have:

∫ (log(1 + u² - 2u + 1) / u²) du

= ∫ (log(u² - 2u + 2) / u²) du.

Now, let's split the logarithm using the properties of logarithms:

∫ (log(u² - 2u + 2) - log(u²)) / u² du

= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.

We can simplify the second integral:

∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.

Using the power rule for integration, we can integrate both terms:

∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.

Now, let's focus on the second integral:

∫ (log(u) / u³) du.

This integral does not have a simple closed-form solution in terms of elementary functions.

It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).

Therefore,

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

What was Huda’s error?

Huda found the product of –3 and 9 as positive.
Huda subtracted –7 from 27 incorrectly.
Huda did not follow the order of operations.

Answers

Huda's error in evaluating (3) squared incorrectly led to the incorrect final result.

The correct answer should be -20, not 34.

Huda's error was that she evaluated (3) squared incorrectly.

Instead of calculating 3 squared as 9, she mistakenly considered it as 3. This error led to incorrect subsequent calculations and the final result of 34, which is not the correct answer.

To evaluate the expression correctly, let's go through the steps:

Negative 3 (8 minus 5) squared minus (negative 7) $= -3(3)^2 - (-7)$

First, we simplify the expression within the parentheses:

$-3(3)^2 - (-7) = -3(9) - (-7)$

Next, we evaluate the exponent:

-3(9) - (-7) = -3(9) + 7

Now, we perform the multiplication and addition/subtraction:

-3(9) + 7 = -27 + 7 = -20

Suppose that you roll two dice. You will be paid $20 if you roll a double. You will not receive anything
for any other outcome. How much should you be willing to pay for the privilege of rolling the dice?
Please round your answer to the nearest cent.

Answers

There are 36 possible outcomes when rolling two dice, and only 1 of those outcomes results in a double. Therefore, the probability of rolling a double is 1/36, or approximately 0.028.

If you are willing to pay $20 to roll the dice, then you are effectively paying a premium of $20 for a probability of 0.028 of winning. This means that the expected value of rolling the dice is 0.028 * $20 = $0.56.

Therefore, you should be willing to pay up to $0.56 for the privilege of rolling the dice. Rounded to the nearest cent, this is $0.56.

The percentage decrease in the number of students will be 6.6%. The correct option is B.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that last year, Springfield Middle School had 620 students. This year, it has 582 students.

The percentage decrease will be calculated as:-

Percentage decrease = ( 620 - 582 ) / 582

Percentage decrease = ( 38 / 582) = 0.0652

Percentage decrease = 0.0652 x 100 = 6.52% ≅ 6.6%
