<u>Solution:</u> 48cm/s^2
<u>Working:</u>
A = s^2
Derivate s^2 (as it is area formula) which gives
dA/dt = 2s dL/dt
dL/dt = 6cm/s
Hence,
2(6) = 12
Side: 4cm
Hence,
dA/dt = (4)(12) = 48cm/s^2

Take the # in the last week and times it by 3.5 than you should get the next week. ex: if you wanted to find the 9th week you could do 84 times 3.5 8 times
Answer:
<u>The width is 1.67 or 1 2/3 feet approximately</u>
Step-by-step explanation:
Area of the dog pen = 14 1/5 = 14.2 square feet
Length of the pen = 8 1/2 = 8.5 feet
Width of the pen = x
Let's recall that the formula of the area of a rectangle is:
Area = Length * Width
Replacing with the values we know:
14 1/5 = 8 1/2 * Width
14.2 = 8.5 * Width
Width = 14.2/8.5
Width = 1.67 feet (rounding to the next hundredth)
1.67 ≅ 1 2/3
<u>The width is 1.67 or 1 2/3 feet approximately</u>
