=13 this is the correct answer
I hope this answer help you
Answer:
volume of a cone = 
h/3
= 22/7 or 3.14
r (radius) = 8 ft
h (height) = 16 ft
∴ volume = 22/7 * 8 * 8 * 16/3
= 3.14 * 64 * 16/3
= 1072.76190476

Answer:
9
Step-by-step explanation: 36 divided by 4 is 9.
The given function is
f(x) = 4x - 3/2
where
f(x) = number of assignments completed
x = number of weeks required to complete the assignments
We want to find f⁻¹ (30) as an estimate of the number of weeks required to complete 30 assignments.
The procedure is as follows:
1. Set y = f(x)
y = 4x - 3/2
2. Exchange x and y
x = 4y - 3/2
3. Solve for y
4y = x + 3/2
y = (x +3/2)/4
4. Set y equal to f⁻¹ (x)
f⁻¹ (x) = (x + 3/2)/4
5. Find f⁻¹ (30)
f⁻¹ (30) = (30 + 3/2)/4 = 63/8 = 8 (approxmately)
Answer:
Pedro needs about 8 weeks to complete 30 assignments.
ANSWER:
Y intercept: (0, 2)
X intercept: (6, 0)
STEP-BY-STEP EXPLANATION:
We have the following equation:
The x-intercept is when y is equal to 0 and the y-intercept is when x is equal to 0, therefore:
