Answers

Answer 1

Answer:

Hello! answer: 90

Step-by-step explanation:

I split the trapezoid into 2 then did base × height ÷ by 2 cause the way I split it it made 2 triangles

10 × 12 = 120 10 × 6 = 60 120 + 60 = 180 180 ÷ 2 = 90 therefore 90 is our area Hope that HELPS!

8z = 4x - 32

Please explain step by step

Answers

The solution to the equation 8z = 4x - 32 is z = -4 and x = 8.

What is equation?

An equation is a mathematical statement that states that two expressions are equal. It consists of an equals sign and two expressions, one on each side of the equals sign. Equations are used to solve for the value of the unknown expressions, and can be used to solve problems in various fields such as physics, chemistry, engineering, and mathematics.

1. Start by isolating the z variable by subtracting 4x from both sides of the equation. This will give us: 8z = -32.
2. Divide both sides of the equation by 8. This will give us: z = -4.
3. Finally, substitute z = -4 into the original equation and solve for x. This will give us: 4x = 32, so x = 8.

Therefore, the solution to the equation 8z = 4x - 32 is z = -4 and x = 8.

If I deposit $100,000 in a retirement account that gives 8 % paid annually, what will be balance after 25 years?

Answers

Answer:

$300,000

Step-by-step explanation:

To find 8% of 100,000 all you need to do is multiply 100,000 by .08.

100,000 (.08) = 8,000

The 8,000 accounts for one year, so now you have to multiply 8,000 by 25.

8,000 (25) = 200,000

Now add the initial amount to the additional 200,00 that will be paid to the retirement account.

100,000 + 200,000 = 300,000

The answer is $300,000.

The answer will be 19/10 or 1 9/10

Step-by-step explanation:

Soo... let's simplify 1 2/5 first.

The simplified version of 1 2/5 is 7/5.

and we solve the equation!

since there are two negatives, turn it into a plus!

7/5 + 1/2

5 x 2 = 10 2 x 5 = 10

7 x 2 = 14 1 x 5 = 5

so...

14/10 + 5/10 which will be 19/10, or 1 9/10

The question should be find the answer, not the difference ngl.

Q:write the equation of the line that is given slope an y-intercept?

Slope=Undefined y-intercept= -4

[tex]y = mx + b[/tex]

Answers

Answer:

y = mx - 4

Step-by-step explanation:

m is the slope, while -4 is the y intercept

if the slope is undefined, that means it is just a vertical line. All vertical lines can be written as: x=a with a being the x-intercept. However, you are given a y-intercept. Therefore, it must be on the y-axis. So the equation should be x=0

As a result, $1600 is the answer to the problem equation comes out to be stated problem, which is the estimated rent.

Describe equation.

A mathematical statement known as an equation is created by joining two expressions using the equivalent sign. For instance, 2x - 5 = 15 is an equation. We can find that the variable x has a value of 5 by resolving this equation.

Here,

In New York City, a one-bedroom apartment will cost $1600 in 2020.

Y = mx + c is frequently used as the formula for a straight line graph, where;

gradient = m

The vertical intercept is given by c.

With this knowledge, it is evident from the graph that y = 40x + 800 is the best line of fit for the data presented.

This indicates how much a one-bedroom apartment in New York City will cost in 2020, or 20 years after the year 2000.

y = 40(20) + 800 = $1600

As a result, $1600 is the answer to the problem equation comes out to be stated problem, which is the estimated rent.

Step-by-step explanation:

A simple random sample of 32 men from a normally distributed population results in a standard deviation of 12.9 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normalâ range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute.

Required:
Identify the null and alternative hypotheses.

Answers

Answer:

Null Hypothesis, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute

Alternate Hypothesis, H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute

Step-by-step explanation:

The null hypothesis is basically the problem statement i.e

Pulse rates of men have a standard deviation equal to 10 beats per minute

Hence, H0 = The pulse rates of men have a standard deviation equal to 10 beats per minute

The alternate hypothesis will contradict or negate the null hypothesis i.e

H1 = The pulse rates of men do not have a standard deviation equal to 10 beats per minute

What are the coordinates of the image rectangle for a scale factor of 3 if the center of dilation is the origin?

This doesn’t have a rectangle picture btw
I will mark brainlist

Answers

Answer: Choice B)

Explanation:

You mentioned there isn't a diagram to go with this, but I'm assuming that this problem is referring to a previous problem you posted. In that problem, it mentions that point W is at (1,-2). If we apply the scale factor 3, then we're tripling each coordinate. That means x = 1 becomes x = 3, and y = -2 becomes y = -6

We can write it like this:

(1,-2) ---> 3*(1, -2) = (3*1, 3*(-2) ) = (3, -6)

Only choice B has W'(3,-6) so this is likely the final answer.

If we apply this dilation to every point, then that effectively makes quadrilateral W'X'Y'Z' to be three times longer and taller than compared to quadrilateral WXYZ. In other words, its side lengths are 3 times longer.

50 POINTS Answer the following questions and draw a rough sketch of the function:

f(x)=-x^4+8x^3+8x^2-96x-144

What is the function’s general shape?

Does the function face up or down?

What is the function’s y-intercept?

If one of the factors is (−6), how would you show that on the graph?

Answers

The function's general shape is a downward-opening parabola.

The function faces down The function's y-intercept is -144x - 6 is a factor

What is the function’s general shape?

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

f(x)=-x^4+8x^3+8x^2-96x-144

Express properly

So, we have

f(x) = -x⁴ + 8x³ +8x² - 96x - 144

Next, we plot the graph (see attachment)

From the attached graph, we can see that the function opens down

This means that the general shape is a downward-opening parabola.

Does the function face up or down?

The function faces down (as shown on the graph)

What is the function’s y-intercept?

Here, we set x = 0

So, we have

f(0) = -(0)⁴ + 8(0)³ + 8(0)² - 96(0) - 144

Evaluate

f(0) = -144

So, the y-intercept is -144

How to show that one of the factors is (x - 6) on the graph?

We start by setting the factor to 0

So, we have

x - 6 = 0

Solve for x

x = 6

From the graph;

When x = 6, y = 0

This means that x - 6 is a factor
