52-8=44
44-6.50=37.50
37.50/2=18.75
18.75 per shirt

Answer:

The lengths 7, 40 and 41 cannot be sides of a right triangle. The lengths 12, 16, and 20 can be sides of a right triangle.

Step-by-step explanation:

You can test this by using the Pythagorean theorem, which states a^2+b^2=c^2

with 7,40 and 41

7^2+40^2 does not equal to 41^2

but with 12,16, and 20

12^2+16^2=20^2

therefore, the last statement is correct.

What is CBE for this one I need help??

rusak2 [61]

Step-by-step explanation:

42+5x+7x+6=180 (sum of angles in straight line is 180)

48+12x=180
12x=180-48
12x=132
x=132/12
x=11

now m <CBE =7x+6=7×11+6=77+6=83

Can someone fr help me with this like right now i’ll appreciate it sm

rjkz [21]

Step-by-step explanation:

Since

$\frac{108}{72} = \frac{3}{2}$

$\frac{72}{48} = \frac{3}{2}$

$\frac{48}{32} = \frac{3}{2}$

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

$y = a(b) {}^{x}$

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

$y = 32 ( \frac{3}{2} ) {}^{x}$

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.

2013- 162

Find an equation of a line that is tangent to the graph of f and parallel to the given line. Please see picture

ivanzaharov [21]

Answer:

y = 3x - 2 (smaller y-intercept)

y = 3x + 2 (larger y-intercept)

Step-by-step explanation:

First let's write the generic equation of a line:

y = ax + b

This line needs to be parallel to the line 3x - y + 5 = 0, so it needs to have the same slope of this line.

The line 3x - y + 5 = 0 has a slope of 3, so our line has a = 3:

y = 3x + b

Now we need to find the values of b that make this line tangent to the function f(x) = x^3

Let's first find the derivative of f(x) in relation to x:

df(x)/dx = 3x^2

This derivative is the slope of the tangent line to the function for any value of x. We need a slope of 3, so:

3x^2 = 3

x^2 = 1

x = ±1

Now, to find the y-values, we have:

f(1) = 1^3 = 1

f(-1) = (-1)^3 = -1

So, using the points (1,1) and (-1,-1) in our parallel line, we have:

first line using (1,1) : 1 = 3*1 + b

b = -2

second line using (-1,-1) : -1 = -3*1 + b

b = 2

The value of b is the y-intercept of the line, so the line with smaller y-intercept is y = 3x - 2, and the line with larger y-intercept is y = 3x + 2
