Answer:

y = 3/2 x - 11

Step-by-step explanation:

y = -2/3 x + 5; slope = -2/3

Perpendicular line, slope is reciprocal and opposite so slope of the line that is perpendicular to the y = -2/3 x + 5 is 3/2

Passes through (8,1)

Equation

y -1 = 3/2 (x - 8)

y - 1 = 3/2 x - 12

y = 3/2 x - 11

Line AB contains points A ( -3,5) and B (-3,3). Line AB has a slope that is

Alex_Xolod [135]

Answer:

slope that is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(- 3, 3)

m = $\frac{3-5}{-3+3}$ = $\frac{-2}{0}$

Division by zero is undefined

Thus the slope of AB is undefined

At a rental car company, a customers daily rental charge D (in dollars) for m miles driven is determined by the function D = 35

lianna [129]

Answer:

See below

Step-by-step explanation:

<u>Given function:</u>

D = 35 + 0.4m

m represents the domain and D represents the range of the function, therefore m = x, D = y

<u>Filling in the table:</u>

for x = 10, y = 35 + 0.4*10 = 35 + 4 = 39 and so on for the rest of the values

x = 10, 30, 50, 75, 100
y = 39, 47, 55, 65, 75

Answer:

The area of the resulting cross section is $78.5\ m^{2}$

Step-by-step explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

$A=\pi r^{2}$

we have

$\pi=3.14$

$r=10/2=5\ m$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(5)^{2}=78.5\ m^{2}$
