Step-by-step explanation:
Volume of cylinder formula:
<h3>Given</h3>
Find r by substituting given values:
- 64π = πr²*4
- 64π = 4r²π
- 16 = r²
- r = √16
- r = 4 m
Correct choice is A.
Answer: 12.
To solve this problem, let's first solve for x. Thi is easiest done by figuring what QR is in terms of x using two equations, both from different lines.
In the first line:
QR = 15 - 4x.
In the third line:
QR = 13x - 1 - x = 12x - 1.
Now, we have to set these equations equal to each other.
15 - 4x = 12x - 1
15 = 16x - 1
16x = 16
x = 1
Next, we take line three, 13x - 1, and substitute x as 1. The answer is 12.
Answer:
quadrant 4
Step-by-step explanation:
Answer:
A = 236,000 (1.04)^t
population in 2009 : 335,902 people
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form) = 4/100 = 0.04
t= years passed from 2000
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04)^t
A = 236,000 (1.04)^t
Population in 2009.
t = 2009-2000 = 9
A = 236,000 (1.04)^9
A = 335,902 people
