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

P(d) = 10 * 1.08^{d} ......equation 1

Substituting into the formula, we have;

P(1) = 10 * 1.08^{1}

P(1) = 10 * 1.08

P(1) = 10.08

Therefore, option (a) and (b) are incorrect.

c. To find the growth factor per day;

An exponential function is given by the formula;

y = mg^{x} .....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;

P(1) = 10 * 1.08^{\frac {1}{2}}

Therefore, option e is correct.

How do i factor s^2+9s=-20
Talja [164]
To factor you have to do this: 

s^2 + 9s = -20
      + 20    +20

s^2 + 9s + 20 = 0

now you need to numbers that multiplied give you 20 
and then those same 2 numbers have to add to 9

5 x 4 = 20
5+ 4 = 9

(x + 4) (x+ 5)

that means that x= -4, and -5
