The number of students at a certain school is 1220 and is increasing at a rate of 10%
per year. Identify the exponential growth function to model this situation. Then find
the number of students in the school after 7 years.
O y= 1220(110) 2000
y=1220(1.1): 2300
y = 1220(1.01): 2343
y = 1220(1.1): 2377

.

Step-by-step explanation:

The general exponential growth equation is given by :-

, where A = Initial value

r= Rate of growth

x = time

Given , The number of students at a certain school is 1220 and is increasing at a rate of 10%  per year.

i.e. A= 1220 , r=10% = 0.1 [In decimal]

Then, the required function would be :

At x= 7 , we get

The number of students in the school after 7 years =2377

Hence, the correct option is .

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
