The expression is


Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
y is the population
x is the number of years
r is the rate of change
a is the initial value or y-intercept
we have

substitute the given values


For x=5 years
substitute in the exponential equation


a complementary angle is 90 degrees, so, if the angle measures 4 more than a complimentary angle, it is 94 degrees.
