inches.

Step-by-step explanation:

First, let us split this figure into two parts, a parallelogram and a semi-circle. The perimeter of the parallelogram will be

inches. We do not add the additional 5 inches due to it being stuck to the semi-circle, and hence that additional 5 inches is not part of the perimeter.

To find the curved perimeter of the semi-circle, we use the formula

and then divide it by two as the above formula is used for a whole circle. The diameter is 5 inches and thus the curved perimeter is

The total perimeter is then

Using a calculator, we get

and the answer is

inches when corrected to the nearest hundredth.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
