The number of animals in a population is 775, and it increases by of 51% each year. a. model the situation with an exponential function. b. find how many animals there will be in 10 years. c. how many years will it take for the population to become 1150. show all work!

Answer(a):

Exponential growth formula is given by

Where preset population = P= 775

Rate of increase = r = 51% = 0.51

t= number of years

A= Future value.

Plug these values into above formula:

Hence required exponential function is

Answer(b):

plug t=10 years

which is approx 47761.

Answer(c):

Plug A=1150

0.957643654334=t

Which is approx 1 year.

1) is right

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
