Answer:

Sample Response: Substitute the known circumference into the formula C = πd. Divide by π to find the diameter. Then divide the diameter in half to find the radius. Substitute the radius into the area formula, A = πr2. Square the radius and multiply by π to get the area.

Answer:

24 square units

Step-by-step explanation:

The area of a parallelogram is given by the formula ...

A = bh

where A represents the area, b the length of the "base", and h the "height" measured at right angles to the base.

Here, it is convenient to use one vertical side of the figure as the base. You can count the grid squares to see that it is 8 units long.

The height is then the distance from one vertical side to the other. Again, you can count the grid squares to see that it is 3 units.

The area is the product of these dimensions:

A = (8 units)·(3 units) = 24 units^2

P(n) models the price (in dollars) of a pack of n bulbs at a certain store.
ycow [4]

Answer:

Option A.

Step-by-step explanation:

The given question is incomplete. Here is the complete question.

P(n) models the price (in dollars) of a pack of n bulbs at a certain store.

When does the price of a pack increase faster ?

n             4             10            12

P(n)        12            25           28

When does the price of a pack increase faster ?

A. Between 4 and 10 bulbs

B. Between 10 and 12 bulbs

C. The price increases at the same rat over both the intervals.

To solve this question we will find the rate of increase in the prices per pack in the given intervals.

From n = 4 to n = 10

Rate of increase in price = \frac{25-12}{10-4}

                                         = \frac{13}{6}

                                         = 2.166 ≈ $2.17 per pack

From n = 10 to n = 12

Rate of increase in price = \frac{28-25}{12-10}

                                         = \frac{3}{2}

                                         = $1.5 per pack

Therefore, price per pack increases faster between n = 4 and n = 10 as compared to n = 10 to n = 12.

Option A is the answer.
