Answer:
p = 17 and -15
Step-by-step explanation:
If q is directly proportional to (p-1)², this can be written as;
q = k(p-1)²
If q = 20 when p = 3
20 = k(3-1)²
20 = 2²k
20 = 4k
k = 5
To get p wen q = 80
80 = 5(p-1)²
16 = (p-1)²
p-1 = ±√16
p-1 = 16 and p-1 = -16
p = 17 and p=-16+1
p = 17 and -15
First find the volume of the cylinder.
The formula is: V=πr²h
Plug the numbers in the figure into the formula.
V=πr²h
V=π×3²×10
V=π×9×10
V=π90
V=282.743
Therefore, the volume of the cylinder is approximately 282.7in³
Find the volume of the rectangluar prism.
V=lwh
V=12×7×4
V=84×4
V=336
Therefore, the volume of the rectangular prism is 336in³
Add the volumes:
282.7+336=618.7
The volume of the composite solid is approximately 618.7in^3
Answer:
A. (x*2.5)*x
B. (32*2.5)*32=2560
Step-by-step explanation:
Exponential change can be modeled by:
N = N(0) x λⁿ; where λ is the rate of change. It is greater than 1 when there is growth and less than 1 when there is decay. n is the number of time periods passed.
λ is 1 + 0.083 = 1.083
N(0) is the initial value of 750
n is 2050 - 2005 = 45 years
N = 750 x (1.083)⁴⁵
= 27,000 fish
