Answer:

  A' = 6(3t +1)

Step-by-step explanation:

The area is the square of the side length, so ...

  A = (3t +1)²

The derivative with respect to t is then

  A' = 2(3t +1)·(3) = 6(3t +1)

If you like, you can multiply out the area expression first, then differentiate.

  A = 9t² +6t +1

  A' = 18t +6

This can be factored, if you like, to ...

  A' = 6(3t +1)

Answer:

  $6,797.09

Step-by-step explanation:

The area of the floor is ...

  (21 ft)(28 ft) = 588 ft²

Then the cost of the carpet material is ...

  (588 ft²)($10.45/ft²) = $6,144.60

The subtotal with installation fee is ...

  $6,144.60 +149.00 = $6,293.60

Adding the sales tax multiplies this amount by 1 +8% = 1.08, so the final price is ...

  1.08 × $6,293.60 = $6,797.09 . . . total price

Points P, Q, and R are shown on the number line. What is the distance between point P and point Q? P(-76) Q(-24) R(0) A) 52 unit
Amiraneli [1.4K]

Answer:

A) 52 units

Step-by-step explanation:

The length of a line joining 2 points on a number line is given by the difference between the co-ordinates of the 2 points.

Therefore PQ= \left ( Q \right )-\left ( P \right )= \left ( -24 \right )-\left ( -76 \right )= 52

Hence the length of the line is 52 units
