What is equation?

An equation is a mathematical statement that shows the equality of two expressions, usually with an equal sign "=" in between them. An equation can contain variables, constants, and operators. The variables are represented by letters and can take on different values, while constants are fixed values that do not change. Operators include mathematical symbols like plus, minus, multiplication, and division, as well as exponents and logarithms.

Here,

We are given that the population at the start of year 1 (P1) is 400. Using the recurrence relation Pt + 1 = 1.01Pt, we can find the population at the start of year 2 (P2) and year 3 (P3) as follows:

P2 = 1.01 * P1 = 1.01 * 400 = 404

P3 = 1.01 * P2 = 1.01 * 404 = 408.04

(4.5x − 5) − (3.5x − 10)

Answers

Answer:

To simplify this expression, we can use the distributive property of multiplication over addition/subtraction to remove the parentheses:

(4.5x − 5) − (3.5x − 10)

= 4.5x - 5 - 3.5x + 10 (distributing the negative sign to the second term in parentheses)

= (4.5x - 3.5x) + (10 - 5) (grouping like terms)

= 1x + 5

= x + 5

Therefore, (4.5x − 5) − (3.5x − 10) simplifies to x + 5.

Answer:

1x+5

Step-by-step explanation:

You are trying to simplify the equation

First distribute the "-"

-(3.5x)=-3.5x -(-10)=10

4.5x-5-3.5x+10

Now combine like terms

4.5x-3.5x=1x -5+10=5

How much greater is the average temperature on Earth the the average temperature on Jupiter? Jupiter's temperature is -166, Earth's temperature is 59.

Answers

Answer: 107 I think

Step-by-step explanation:

The average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Jupiter's temperature is -166, and Earth's temperature is 59.

We have to find the temperature difference between the earth and Jupiter.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

The average temperature on Earth and the average temperature on Jupiter are obtained by applying the subtraction operation as,

Δt= T(earth) - T(jupiter)

Δt=59-(-166)

Δt=59+166

Δt=225 degrees

Thus, the average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.

find the coordinate of a triangle a(1,3) , b(2,5) and c(3,3) after being rotated about fixed point p(2,4) by 45 in clockwise direction and then translate (3,4) .

Answers

After the transformation point A will be at (5, 6.586), point B will be at (5.121, 7.121) and point C will be at (6.121, 5.121).

STEPS FOR FIND THE COORDINATE

The coordinates of a triangle after rotation and translation can be found using the following steps:

Rotation: To rotate a point (x, y) about a fixed point (a, b) by an angle θ (in this case, 45 degrees in the clockwise direction), you can use the following formulas to find the new coordinates:

x' = (x - a) * cos(θ) - (y - b) * sin(θ) + a

y' = (x - a) * sin(θ) + (y - b) * cos(θ) + b

Translation: To translate a point (x, y) by a distance (dx, dy) in the x and y direction, you can use the following formulas to find the new coordinates:

x' = x + dx

y' = y + dy

So for the first vertex of the triangle(1,3) after being rotated about fixed point p(2,4) by 45 in clockwise direction

x' = (1 - 2) * cos(45) - (3 - 4) * sin(45) + 2 = -1.121 + 1.121 + 2 = 2.000

y' = (1 - 2) * sin(45) + (3 - 4) * cos(45) + 4 = -0.707 - 0.707 + 4 = 2.586

And after the translation (3,4) for point A

x' = 2 + 3 = 5

y' = 2.586 + 4 = 6.586

similarly for point B(2,5) will be (5.121,7.121)

and for point C(3,3) will be (6.121,5.121)

So after the transformation point A will be at (5, 6.586), point B will be at (5.121, 7.121) and point C will be at (6.121, 5.121)

The probability that the child will also have diabetes is about 1/2500 so the above-given statement is (B) FALSE.

What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. By simply dividing the favorable number of outcomes by the total number of possible outcomes, the probability of an event can be determined using the probability formula.

So, if a 30-year-old woman with type-1 diabetes has a child, then the probability that the child will also have diabetes is about 1%:

If a child is born before a woman is 25 = 1/25If a child is born after a woman is 25 = 1/100

Now,

1/25 × 1/100 = 1/2500

Therefore, the probability that the child will also have diabetes is about 1/2500 so the above-given statement is (B) FALSE.

January of 1998. The value of the stock is expected
to increase by 7.5% per year. Use a graph to predict
the year the value of Mira's stock will reach $650.

Answers

To predict the year when the value of Mira's stock will reach $650, we can use the given information that the value of the stock is expected to increase by 7.5% per year. We can create a graph to visualize the growth of the stock value over time.

Let's assume that the x-axis represents the years starting from 1998 and the y-axis represents the value of the stock. We'll plot the initial value of $300 in January 1998 and then project the growth based on an annual increase of 7.5%.

Here's a rough representation of the graph:

```
| /
650| /
| /
| /
|/
|_________________
1998 1999
```

Based on this graph, it appears that the value of Mira's stock will reach $650 in the year 1999.

Please note that this is a simplified approximation based on the given growth rate and does not take into account factors such as market fluctuations or compounding. The actual year of reaching $650 may vary depending on various real-world factors.

You want to take out a $219,000 mortgage (home loan). The interest rate on the loan is 4.5%, and the loan is for 30 years. Your monthly payments are $1,109.64. How much will still be owed after making payments for 15 years? Round your answer to the nearest dollar.

Answers

After making payments for 15 years, the amount still owed on the mortgage would be approximately $145052.36.

To determine how much will still be owed after making payments for 15 years, we can use the formula for the remaining balance on a mortgage:

Remaining balance = P ((1 + r)ⁿ - (1 + r)ᵇ) / ((1 + r)ⁿ - 1)

where:

P = the initial loan amount (in this case, $219,000)

r = the monthly interest rate (which is the annual interest rate divided by 12)

n = the total number of monthly payments (which is 30 years times 12 months per year, or 360 months)

b = the number of monthly payments made so far (which is 15 years times 12 months per year, or 180 months)

First, we need to calculate the monthly interest rate:

r = 4.5% / 12 = 0.00375 = 0.375%

Next, we can plug in the values to get:

Remaining balance = $219,000 ((1 + 0.00375)³⁶⁰- (1 + 0.00375)¹⁸⁰) / ((1 + 0.00375)³⁶⁰ - 1)

= $145052.36

x =2cost - 3sint, x'' +x =0

Answers

Given :

A function , x = 2cos t -3sin t .....equation 1.

A differential equation , x'' + x = 0 .....equation 2.

To Find :

Whether the given function is a solution to the given differential equation.

Solution :

First derivative of x :

$x'=\dfrac{d(2cos t - 3sin t)}{dt}\\\\x'=\dfrac{d(2cost)}{dt}-\dfrac{(3sint)}{dt}\\\\x'=-2sint-3cost$

Now , second derivative :

$x''=\dfrac{d(-2sint-3cost)}{dt}\\\\x''=-\dfrac{d(2sint)}{dt}-\dfrac{d(3cost)}{dt}\\\\x''=-2cost+3sint$

( Note : derivative of sin t is cos t and cos t is -sin t )

Putting value of x'' and x in equation 2 , we get :

=(-2cos t + 3sin t ) + ( 2cos t -3sin t )

= 0

So , x'' and x satisfy equation 2.

Therefore , x function is a solution of given differential equation .

Answer:

29 degrees

Step-by-step explanation:

Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees
