Answer:
10 * 20 cm.
Step-by-step explanation:
Let the width of the base = x, then it's length is 2x cm and the area = 2x^2 cm^2.
Volume = 1/3 * height * area of the base
4000 = 1/3 * 60 * 2x^2
2x^2 = 4000 / (1/3 * 60)
2x^2 = 4000 / 20 = 200
x^2 = 200/2 = 100 cm.
x = 10 cm.
So the dimension of the rectangle = 10 * 20 cm.
Answer:
4x(5)+1×(3.20)= 20+3.20=23.20
Step-by-step explanation:
Answer:
A) x= -9
B) x=5
C) x=5
D) x=5
Step-by-step explanation:
Answer: D
Step-by-step explanation: Plug in for x, since g(x) represents y we can set it up as y = (1/4x) ^ 2 . 4 /4 = 1 and 1 ^ 2 = 1, so y=1, which fits it.
