A) To find the edge length from the volume you use the formula:
e = V¹ˡ³ (to the power of 1/3) where e is the edge length.
Substitute in the volume:
e = 64000¹ˡ³
Solve:
Edge length = 40 inches
b) To find the surface area from the volume you use the formula:
s = 6V²ˡ³ (to the power of 2/3) where s is the surface area.
Substitute in the volume:
s = 6 x 64000²ˡ³
Solve:
s = 384000²ˡ³
Surface area = 9600 square inches
The answer is 87,455
P(x) = P(0) * nˣ
P(x) - the final population after period x
P(0) - the initial population
n - the growth factor in decimal
x - period of time
x = 3 hours
P(3) = 25,143
P(0) = ?
n = 100- 34% = 66% = 0.66
P(x) = P(0) * nˣ
25,143 = P(0) * 0.66³
25,143 = P(0) * 0.287496
P(0) = 25,143 / 0.287496
P(0) ≈ 87,455
Answer:
c. (3, 2)
Step-by-step explanation:
Equating the values of y :
- -x + 5 = x - 1
- x + x = 5 + 1
- 2x = 6
- <u>x = 3</u> [x-coordinate of the solution]
Finding y by substituting x in one of the equations :
- y = x - 1
- y = 3 - 1
- <u>y = 2</u> [y-coordinate of the solution]
Solving :
- Solution = (x, y)
- Solution = (3, 2)
