Let the length be l and width be w.
l = w + 4

Area = length x width
396 = (w + 4)w
w² + 4w - 396 = 0
w = 18, w = -22
Negative width not possible so answer discarded.

Width = 18 feet.

a snowball is rolled down a giant hill. the radius of the snowball grows. every second the radius increases by 0.36 inches. four
Bad White [126]

Based on the fact that the radius of the snowball increases by 0.36 inches every second, the linear function can be found to be y = 0.36x + 1.66

<h3>How to find the linear function?</h3>

The linear function is the function that shows how to change in the rate of the independent variable would affect the rate of change in the dependent variable.

The linear function takes the form:

y = mx + b

y = dependent variable

m = slope or change in radius of snowball

x = seconds

b = y-intercept

Solving for the y-intercept gives:

3.1 = 0.36(4) + b

b = 3.1 - 1.44

= 1.66

The linear function is therefore:

y = 0.36x + 1.66

Please help and thank you

Answer:

D

Step-by-step explanation:

The parent graph (red) is y = x^2

To get that graph to move right 4 units, the graph become y1  = (x - 4)^2

To get the graph to move up 1 unit, add 1 on the right. y2 = (x -4)^ + 1

The answer is D

Note: getting a graph to move left or right is a bit anti-intuitive. If you want it to move right, you have to subtract a number from x before before squaring the result. Your intuition would tell you to add the number, but that moves the graph left.

it is possible to use both fractional and decimal forms to multiply and divide. What are the advantages and disadvantages of usi
nlexa [21]
If you use fractions, the answer you get will always be an exact answer in the form of a fraction. resorting to decimals means that you may run into rounding errors and therefore get only an approximate answer. e.g. the fraction 1/3 cannot be exactly represented by a decimal.fractions can be easier to represent the number rather then using decimals which involve writing out many numbers it does not affect the accuracy of the answer UNLESS you are rounding up and down the numbers
