Volume of cylinder = πr²h
= π × 5² × 14

Hey Gary!

The volume of a cylinder is PiR^2h, or 3.14(r^2)h.
Let's define our measures.
Pi is 3.14 (simplified). However, our answer is requested in terms of Pi.
Our radius is 5.
Our height is 14.
Let's plug in our numbers.

5^2 • 14 • Pi
5^2 = 25
25 • 14 = 350.

350Pi is our answer.
However, rememver that we need to end our answer in units cubed, as we are using a 3-dimensional figure. Our answer is 350Pi in^3.
Your answer is B.)

I hope this helps!

Complete the sentences to describe the function f(x) = 2x^2+16x/16x^3-x the function is discontinus at

wel

Answer:

The answer is " $\bold{\frac{2(x+8)}{(4x^2- 1)(4x^2+ 1)}}$ ".

Step-by-step explanation:

$\to f(x) = \frac{2x^2+16x}{16x^3-x}$

$= \frac{2x(x+8)}{x(16x^2-1)}\\\\= \frac{2(x+8)}{(16x^2-1)}\\\\= \frac{2(x+8)}{((4x)^2-(1)^2)}\\\\= \frac{2(x+8)}{(4x^2- 1)(4x^2+ 1)}\\\\$

3x-2y=6 whats the slope, x-int and y-int

Alex Ar [27]

Answer:

Slope: 3/2

X-intercept: 2/3y + 2

Y-intercept: 3/2x - 3

Step-by-step explanation:

For the slope you have to put it in y intercept form to become y = 3/2x - 3

The slope is 3/2. x intercept is the opposite. x = 2/3y - 2

At the city museum, child admission is

Vlad1618 [11]

Let's make
A = adult tickets sold
C = child tickets sold
A + C = 162
5.90C + 9.50A = 1182.60

if .. A+C = 162 then A = 162 - C
substitute (162 - C) for A in the other equation.

5.9C + 9.5(162-C) = 1182.6
5.9C + 1539 - 9.5C = 1182.6
-3.6C + 1539 = 1182.6
-3.6C = 1182.6 - 1539
-3.6C = -356.4
C = -356.4/-3.6
C = 99 tickets

Two hot air balloons are traveling along the same path away from a town, beginning from different locations at the same time. He

Answer:

D. Henry's started farther, went faster

Step-by-step explanation:

Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...

y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value

Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.

Henry started farther from town and traveled faster.
