I’m doing the same thing right now, idk the last 2 but the first few are Pythagorean theorem, substitution, substitution property of equality, and square root property of equality
Good luck!!!
Answer:
negative slope
Step-by-step explanation:
using the slope equation you can see that the slope is -53
Answer: $1,350
Step-by-step explanation:
45 hours x 10 dollars/hour = 45x10 dollars = 450 dollars/week
450 dollars/week x 3 weeks = 450x3 dollars = 1350 dollars
Answer:
1(-4)
Step-by-step explanation:
I think it's 1(-4)
since it's moving 1 number over, four times. and if you multiply, the answer -4.
I'm pretty sure this is the answer.
Let the square base of the container be of side s inches and the height of the container be h inches, then
Surface are of the container, A = s^2 + 4sh
For minimum surface area, dA / ds + dA / dh = 0
i.e. 2s + 4h + 4s = 0
6s + 4h = 0
s = -2/3 h
But, volume of container = 62.5 in cubed
i.e. s^2 x h = 62.5
(-2/3 h)^2 x h = 62.5
4/9 h^2 x h = 62.5
4/9 h^3 = 62.5
h^3 = 62.5 x 9/4 = 140.625
h = cube root of (140.625) = 5.2 inches
s = 2/3 h = 3.47
Therefore, the dimensions of the square base of the container is 3.47 inches and the height is 5.2 inches.
The minimum surface area = s^2 + 4sh = (3.47)^2 + 4(3.47)(5.2) = 12.02 + 72.11 = 84.13 square inches.
