In the year 2006, a company made $2.4 million in profit. For each consecutive year after that, their profit increased by 12%. Ho
Dmitriy789 [7]

Answer:

Step-by-step explanation:

For each consecutive year after that, their profit increased by 12%. The growth is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the profit made after t years.

t represents the number of years.

P represents the initial profit made.

r represents rate of increase.

From the information given,

P = 2.4 × 10^6

r = 12% = 12/100 = 0.12

t = 4 years

Therefore,

A = 2.4 × 10^6(1 + 0.12)^4

A = 2.4 × 10^6(1.12)^4

A = 3776446.5

Hi there!

To find the area of the kite, we find the area of both triangles and add them up.

8.5 + 8.5 = 17

17 × 4.93 = 73.81
73.81 ÷ 2 = 36.905

17 × 10.2 = 173.4
173.4 ÷ 2 = 86.7

36.905 + 86.7 = 126.805

The area is the kite is 126.805 m squared.

Hope this helps!
