4. Consider the following situation: enrollment at a school is initially 322 students and
grows by 4% per year. Write an equation to represent this situation, and use it to predict
the number of students at the school in 5 years.

392 students

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

where

y is the number of students at the school

x is the number of years

r is the rate of change

a is the initial value

we have

substitute

For x=5 years

substitute

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
