A rectangle initially has dimensions 3 cm by 6 cm. All sides begin increasing in length at a rate of 3 cm divided by s 3 cm/s. A
Setler [38]

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

Consider the following sequence of numbers.
Leto [7]

Answer:

Blank 1 is -3

Blank 2 is 183

Step-by-step explanation:

Let r be common ratio

r =  \frac{ - 9}{3}  \\ r =  - 3

Sum of first 5 terms

s =  \frac{a( {r}^{n}  - 1)}{r - 1}  \\ s =  \frac{  3( {( - 3)}^{5} - 1)  }{ - 3 - 1}  \\ s = 183
