There's no equation represent the pythagorean theorem in the options. The option A is closed to pythagorean theorem, except the b² should be under root.

Pythagorean Theorem is supposed to be like this
c= \sqrt{a^{2}+b^{2}}

(x²+10x+7)(2x-1) = 2x³+19x²+4x-7 show the steps
sasho [114]
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

Why is the growth factor +1 plus r for an exponential growth function?
Serga [27]

Answer:

The exponential growth model is given by this general expression:

y = a (1+r)^t

And the exponential model decay model is given by:

y = a (1-r)^t

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 t_1 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:

y = a(b)^x

Where:

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

The exponential growth model is given by this general expression:

y = a (1+r)^t

And the exponential model decay model is given by:

y = a (1-r)^t

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 t_1 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.

Jeanette's sister charges $5.50 per hour before 9:00 pm for babysitting and $8 per hour after 9:00 pm. She finished babysitting
Sati [7]

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
