Tyler is self-employed sheet metal worker. He purchased 25 sheets of aluminum that measures 4 feet by 8 feet. The cost is $4000.

25 sheets at 4000 per sheet.......4000/25 = $ 160 per sheet <==

A = L * W
A = 4 * 8
A = 32 sq ft....multiply by 25 because he bought 25 of them
25 * 32 = 800 sq ft

4000/800 = $ 5 per sq ft <==

PLEASE HEPP IM STUCK

Ann [662]

Answer:

m = -4

Step-by-step explanation:

We are given that a line intersects the points (-2, 9) and (3, -11).

We want to write the slope of this line.

The slope (m) can be found using the formula $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points.

Even though we have everything we need to calculate the slope, let's label the values of the points to avoid any confusion & mistakes.

$x_1=-2\\y_1=9\\x_2=3\\y_2=-11$

Now substitute these values into the formula (remember that the formula has subtraction).

m= $\frac{y_2-y_1}{x_2-x_1}$

m= $\frac{-11-9}{3--2}$

Simplify.

m= $\frac{-11-9}{3+2}$

Subtract the values on top.

m= $\frac{-20}{3+2}$

Now add the values on the bottom together.

m= $\frac{-20}{5}$

Now divide -20 by 5.

<u>m = -4</u>

Write an exponential function y= ab^x for a graph that includes (1,15) and (0,6)

slava [35]

<span>basically you write an exponential function for y=ab^x for a graph that includes (1,15) and (0,6)
then using (0,6) you get: 6 = ab^0
and using (1,15) you get 15 = ab^1

Equations:
a = 6
ab = 15
So, b = 15/6 = 5/2
Equation:
y = 6(5/2)^x</span>

Which of the following describes the transformations of g (x) = negative (2) Superscript x + 4 Baseline minus 2 from the parent

o-na [289]

Answer: First option.

Step-by-step explanation:

Below are some transformations for a function $f(x)$ :

1. If $f(x)+k$ , the function is shifted "k" units up.

2 If $f(x)-k$ , the function is shifted "k" units down.

3. If $f(x-k)$ , the function is shifted "k" units right.

4. If $f(x+k)$ , the function is shifted "k" units left.

5. If $-f(x)$ , the function is reflected over the x-axis.

6. If $f(-x)$ , the function is reflected over the y-axis.

Then, given the parent function $f(x)$ :

$f(x)=2^x$

And knowing that the the other function is:

$g(x)=-2^{(x+4)}-2$

You can identify that the function $g(x)$ is obtained by:

- Shifting the function $f(x)$ 4 units left.

- Reflecting the function $f(x)$ 4 over the x-axis.

- Shifting the function $f(x)$ 2 units down.
