Well, if it is increasing at a fixed rate of 2 mm/s, then the volume would still be increasing at a rate of 2 mm/s when the diameter is 80 mm, if I understand your question correctly.
Answer:
the total surface area is 40 + 12 + 15 = 67 square units
Step-by-step explanation:
Refer to the diagram:
the combined area of the top and bottom is 2(5·4) = 40:
the combined area of the ends is 2(1.5·4) = 12; and
the combined area of the front and back is 2( 5 · 1.5) = 15
and so the total surface area is 40 + 12 + 15 = 67 square units

Step 1: Distribute each term of the first polynomial to every term of the
second polynomial. In this case, we need to distribute the 4x and the
–5.

Step-by-step explanation:
When two lines are perpendicular to each other, the product of their slopes is equal to - 1
Here, slope of one line is -2/5
let the slope of another line be m
Therefore, m(-2/5)= -1
=> m = 5/2
option B
Answer:
(0,-5)
Step-by-step explanation:
Terminal minus initial. (3-3, -7+2) = (0,-5)
