Answer:
405 cm²/s
Step-by-step explanation:
The dimensions are increasing at the rate of 3 cm/s, so the dimensions in cm can be described as a function of time by ...
3 + 3t
and
6 + 3t
Then the area is the product of these, or ...
A = (3 +3t)(6 +3t)
A = 9t² +27t +18
and the rate of change of area is given by its derivative with respect to t:
A' = 18t +27
When t=21, the value of this is ...
A'(21) = 18·21 +27 = 405 . . . . cm²/s
Final answer: solve for the the dividend and the divisor. Then divide and you should have the answer of 560
Answer:
The surface area of chest 2 would be 32 ft. The area of the base would be 6 ft
Step-by-step explanation:
If the shape is a square then multiplying the base by 6 would work but it is a rectangle in this case which means some sides are uneven. 4 sides are 6 ft and the other 2 are 4. So 6 x 4 plus 4 x 2 would equal 32
