Part A:we know p(t)=6t and also
A(p)=πp2replace p by 6t
A(t)=π(6t)2=36πt2Part B = 7234.56
Answer:
2x^3 + 13x^2 + 26x + 16
Step-by-step explanation:
x(2x^2 + 9x + 8) +2(2x^2 + 9x + 8)
2x^3 + 9x^2 + 8x + 4x^2 + 18x + 16
2x^3 + 13x^2 + 26x + 16
The answer to number 76 is -3n4
If the width is 3 less than the height, we can say that the width is x, and the height is x+3. As the tank is square based, we can say that the length is also x. If the tank has a capacity of 20, this is the volume of the tank. Using the formula for volume, we get (x)(x)(x+3)=20. We multiply this out to get x^3+3x^2=20. If we think this one through, we can realize that 2 works for x, as 8+12 = 20. This means that the dimensions are 2 by 2 by 2+3, or 5.
|a| = a if a ≥ 0
|a| = -a if a < 0
|-9 - 12| = |-21| = -(-21) = 21
<h3>Answer: |-9 - 12| = 21</h3>
