Check the picture below. Recall, is an open-top box, so, the top is not part of the surface area, of the 300 cm². Also, recall, the base is a square, thus, length = width = x.

so.. that'd be the V(x) for such box, now, where is the maximum point at?

now, let's check if it's a maximum point at 10, by doing a first-derivative test on it. Check the second picture below.
so, the volume will then be at
If you would like to find the numerator of a fraction, you can do this using the following steps:
denominator ... 6 * 5 = 30
numerator ... x = ?
36 = numerator / denominator
36 = x / 30
x = 36 * 30
x = 1080
The correct result would be 1080.
Direct variation has this equation:
y = kx
where k is the constant of variation
y = -5 ; x = -15
y = kx
-5 = k(-15)
-5/-15 = k
1/3 = k
Choice D. y = 1/3 x
Answer:
228
Step-by-step explanation:
Answer:
y = 5/8x - 3
Step-by-step explanation:
(8,2) and (-8,-8)
m=(y2-y1)/(x2-x1)
m = ( -8 -2)/ (-8 - 8)
m = (-10)/(-16)
m = 5/8
y - y1 = m(x - x1)
y - 2 = 5/8(x - 8)
y - 2 = 5/8x - 5
y = 5/8x - 3
