Answer: See below
Explanation:
(x^2+10x+7)(2x-1) = 2x^3+19x^2+4x-7
2x^3-x^2+20x^2-10x+14x-7 = 2x^3+19x^2+4x-7
2x^3+19x^2+4x-7 = 2x^3+19x^2+4x-7
The answer is A. True hope this right
Answer:
The exponential growth model is given by this general expression:

And the exponential model decay model is given by:

Where a the initial amount r the growth factor of rate anf t the time.
The reason with we need to add 1+r in the base of the model is because each period of time
we have an increase of the initial amount by a factor of (1+r) so after n periods we will have (1+r)^n times the initial amount.
Step-by-step explanation:
In general an exponential model is given by this formula:

Where:
a = the constant, b = the base and x x the exponent.

Hey there! :D Jeanette's sister started at 5:00 PM. To get that answer, here's what I did: From 5-9 PM, she earned $22. That's because 5.50 x 4 = 22, then from 10-11, she charged $8 which is 8 x 2 = 16 + 22 = $38. Again, she started at 5 PM.
Hope it Helps and makes sense! :D
