Answer:
±11.18
Step-by-step explanation:
the function is:

and to find the roots we need to find which values of
makes the function result in zero:

solving for
:

A square root has two solutions, one positive and one negative, so the solutions are:
±
≈ ±11.18
the roots of the quadratic equation are +11.18 and -11.18

Answer:
I think it is A, or ,D
Step-by-step explanation:
Answer:
c) The growth factor per days is 1.08
e) The growth factor per hour is 1.08^{1/24}
Step-by-step explanation:
Given the following data;
P(d) = 10 * 1.08^{d} in thousands.
a. To find the number of insects on day 1;
Day, d = 1
......equation 1
Substituting into the formula, we have;



Therefore, option (a) and (b) are incorrect.
c. To find the growth factor per day;
An exponential function is given by the formula;
.....equation 2
Where;
g is the growth factor of a population.
Comparing eqn 2 with eqn 1;
g = 1.08
Therefore, option (c) is correct.
e. To find growth factor per hour;
From equation 1 above;

Therefore, option e is correct.
First, you multiply $7.50 by 0.2 (20%) to get 1.5. Then, you just add 1.5 to 7.5, and your answer is $9.00.
