F(x) = 50,000 (0.8)^x

⇒ y = 50,000 (0.8)^x
⇒ log y = log 50,000 + x log 0.8
⇒ x log 0.8 = log y - log 50,000 = log (y/50,000)
⇒ x = log(y/50,000) / log 0.8
⇒ x = log0.8(y/50,000)

 <span>⇒ f^-1(x)=log0.8(x/50,000)

Answer is D

Hope it helps!

I think that it is B because I'm pretty sure it has to be log of 50,000. But I forgot how to get the rest of it but B is the only one with log of 50k.

A Christmas jar contains 550 m&amp;ms. Of all the m&amp;ms, 2/5 are green and the rest are red. What is the ratio of green to re
vazorg [7]

Answer:

2:3 unless it wants it in total, then 220:330

Step-by-step explanation:

it gives you the answer with the fraction.  A ratio is basically saying with x:y for every x number of one thing there are y number of another.  In this case we know 2/5 will be green, so how many will be red?  3/5.  So for every 2 greens there are 3 reds.

Another way of looking at it is for the totals.  there are 550 total, so 2/5 of that is green.  2/5 of 550 is 220, while 3/5 is 330  so that means of the 550, the ratio is 220:330.  Kinda like simplifying fractions where 220/550 is the same thing as 2/5

The area of a square mural pointed on the side of a building is 110 square feet. What is the best estimate of the side length of
natka813 [3]

Answer:

C

Step-by-step explanation:

Area of a square equals to the square of its side, therefor the side of a given area for a square is the square root of the area.

A = a^{2}\\a = \sqrt{A}\\a = \sqrt{110} = 10.48 ft

R(x)=x^3+5x^2-2x-24 Plot the zero(s) of the function.
nevsk [136]

:) Brainliest pls?

Answer:

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Step-by-step explanation:

I'll find the zeros, aka x-intercepts, and you could probably graph them.

To find the zeros, let's factor this polynomial:

r(x) = (x - 2)(x^2+7x+12)

r(x) = (x - 2)(x + 3)(x + 4)

The zeros are {2, -3, -4} which need to be plotted on the x-axis.
