Answer:
n = 3 + i√11 , 3 - i√11
Step-by-step explanation:
This is a quadratic equation and the first step is to write it in standard form:
5n^2 - 30n + 100 = 0
Divide through by 5:
n^2 - 6n + 20 = 0
Completing the square:-
(n - 3)^2 - 9 + 20 = 0
(n - 3)^2 = -11
n - 3 = i√11 or - i√11
n = 3 + i√11 , 3 - i√11
(2 complex roots).

Answer:
Step-by-step explanation:
You're incorrect. an angle of 155 degrees is an obtuse angle. the angle is obviously an acute angle, as it is under 90 degrees. the answer is 50 degrees, or A.
Answer:
Step-by-step explanation:
we know that
The exponential function is of the form
where
y ---> the number of trucks
t ----> is the time in years
a ---> is the initial value (number of trucks for t=0)
b is the base
r is the rate
b=(1+r)
In this problem we have
substitute
we have the point (1,110)
For t=1 year, y=110 trucks
substitute
solve for b
The rate of growth is
the exponential equation is equal to
<u><em>Verify for the third point of the table</em></u>
For t=2 years
---->is correct
