Answer:

A.) 1764π ft3.

Step-by-step explanation:

Volume = π r^2 h

= 14^2 * 9 * π

= 196*9 * π

= 1764 π ft3.

Answer:

1764 pi ft^3(A)

Step-by-step:

The formula for volume of a cylinder is V=pi(r)^2(H)

Given that r(adius)=14 and H(eight)= 9, the equation is substituted and becomes

V=pi(14)^2(9)

V=pi(196)(9)

V=1764 pi (ft cubed)

Line c has an equation of y=-3/4x-3. Line d is parallel to line c and passes through the points (-2, -2). What is the equation o

blagie [28]

Answer:

y = $\frac{3}{4}$ x - $\frac{7}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{3}{4}$ x - 3 ← is in slope- intercept form

with slope m = - $\frac{3}{4}$

Parallel lines have equal slopes , then

y = - $\frac{3}{4}$ x + c ← is the partial equation of line d

to find c substitute (- 2, - 2 ) into the partial equation

- 2 = $\frac{3}{2}$ + c ⇒ c = - 2 - $\frac{3}{2}$ = - $\frac{7}{2}$

y = - $\frac{3}{4}$ x - $\frac{7}{2}$ ← equation of line d

Answer:

x = 3

Step-by-step explanation:

From the given parallelogram;

m<XWC = m<XYC

Given

m<XWC = 2x+5

m<XYC = 3x+2

Equate

2x+5 = 3x+2

2x - 3x = 2 - 5

-x = -3

x = 3

Hence the value of x is 3

Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

$f(x) = 2x^3 - 3x^2 - 18x - 8$

Substituting x = 2 in the above function,

We get,

$f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8$

$=2(8) - 3(4) - 36 - 8$

$=16 - 12 - 44$

$\implies f(2)= -40$

Hence, the value of f(2) would be -40.
