B. 49 cm 2
c. 96 cm 2
D. 24.5 cm 2
Answer:
Option A. 191cm²
The area of the circle is 191 cm²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 7.8cm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (7.8cm)²
a = 3.14 * 60.84cm²
a = 191.03 cm²
The area of the circle is 191.03 cm²

D. n= 1.25(2.5^t)
Answer: Hello mate!
The initial number produces is 1,250,000 toys per year, and you expect to increase by 150% per year.
an increase of 150% (1.5 in decimal form) means that after a year, the amount of toys produced are:
1,250,000 + 1.5*1,250,000 = 1,250,000*(1 + 1.5) = 1,250,000*2.5
and each year, you multiply the previous quantity by 2.5
then the model (in millions) is, as a function of years:
p(0) = 1.25
p(1) = 1.25*2.5
p(2) = 1.25*2.5*2.5
and so on; you can see that:
p(t) = 1.25*(2.5^t)
So the right option is D.
