Answer 1
Answer:

The end behavior of the following function is that it starts high and ends high.

How do we make a graph of a function?

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

Suppose the considered function whose graph is function of x

Then the values of 'x' (also called input variable, or independent variable) are usually plotted on the horizontal axis, and output values function of x are plotted on the vertical axis.

We have been given a function of x as 2x^4 +x^3

The graph of the given function starts high and ends high.

The function touches the origin in the middle of the line.

Hence, the end behavior of the following function is that it starts high and ends high.

Complete the following proof.Given: m ∠XOY = m ∠WOV
m YZ = m ZW
Prove: m XZ = m ZV

Answers

Answer:

Step-by-step explanation:

m ∠XOY = m ∠WOV

so, m XY = m WV --- (i)

     { If angle subtended by two arcs at the center are equal, then length of arc are equal}

m YZ = m ZW  ------- (ii)    {given}

Add (i) and (ii)

XY + YZ = WV + ZW

XZ = ZV    

Hence proved.

Answer:

Given that m ∠XOY = m ∠WOV then m XY = m WV, because central angles are equal to arcs.

Given: m YZ = m ZW

The addition of arcs XY and YZ make arc XZ, that is: m XY + m YZ = m XZ

The addition of arcs ZW and WV make arc XZ, that is: m WV + m ZW = m ZV

Then, m XZ = m ZV

Which is the best estimate for 25% of 60

Answers

the answer is 15 because 25% is .25 x 60
To find 25% of 60
you multiply 0.25 * 60 which is 15

So, 25% of 60 is 15

Mother gives birth to a 8 pound baby. Every 4 months, the baby gains 3 pounds.If x is the age of the baby in months, then y is the weight of the baby in pounds.

Find an equation of a line in the form y = mx + b that describes the baby's weight.

Answers

Hello!

The equation, y = mx + b is slope-intercept form. In this equation, m is the slope, and b is the y-intercept.

If the baby was exactly 8 pounds when it was born, then the y-intercept is (0, 8) because at zero months, the baby was eight pounds. To find the rate of change, we can use the the y-intercept (0, 8), and the weight of the baby at four months, which is (4, 8 + 3) → (4, 11).

Since we have two points, we can use the slope formula ((y_(2)-y_(1))/(x_(2)-x_(1))) to find the rate of change.

(8 -11)/(0-4) = (-3)/(-4) = (3)/(4).

The rate of change is 3/4.

Therefore, the equation that describes the baby's weight is y = 3/4x + 8.

Melissa plans to purchase a pair of jeans for $39.95. She wants to bring enough money to pay for the jeans plus the sales tax, which is 8.25%. What is her total, including sales tax?

Answers

You have to calculate the 8.25% of $39.95, then add the numbers together. 
So: 8.25% of 39.95 = 3.3 (approximately)
The total is 39.95 + 3.3 = 43.25

Another method is to simply calculate the 108.25% of 39.95, you can get this by multiplying 39.95 with 1.0825.

I really need help.
Thanks <3

Answers

Because they are similar, they have the same proportions. In the bigger polygon, the one side is 25in, and in the smaller one, the side is 5in.
25÷5=5
So, you have to divide 65 by 5 to get your answer. 
65÷5=13
13 inches is the answer
(25)/(65)=(5)/(x)\n25x=325\nx=13
