Find (g • f) ^(3) PLEASE HELLPP

Mathematics

spayn [35]4 years ago

The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=g(f(x))=g(3x-2)=(3x-2)^2=9x^2-12x+4

Now, we can evaluate (g°f) at 3:
g(f(3))=9(3)^2-12(3)+4
g(f(3))=9(9)-36+4
g(f(3))=81-32
g(f(3))=49

We can conclude that the correct answer is c. 49

What choices are equivalent to 48/64
Harrizon [31]
There are no choices so I’m going to assume this is simplification.

Answer:
3/4 —> this is the most simplified version of that fraction.

Explanation:
48/64 can be divided by multiple things to gain fractions. You could divide it by 2 repeatedly until arriving to a fraction wherein you couldn’t split anymore.
Ex.) 48/64 = 24/32 = 12/16 = 6/8 = 3/4
All of the above answers are equivalent to 48/64.
An easier way to reach the final answer of 3/4 would be to find the greatest common factor of 48/64. You can divide both by 16 and then get to 3/4.

Hope this helps!

Answer:

y = −55x + 275

The initial value is 5

Mike's distance from home when he begins cycling

Step-by-step explanation:

The equation of a line is

y= mx+b where m is the slope and b is the y intercept

The y intercept is 275

Two points are (0,275) and (5,0)

The slope is (y2-y1)/(x2-x1) = (0-275)/(5-0) = -275/5 =-55

y = -55x+275

The initial value is when x = 0

When x = 0 , y = 5

y = 12-2x

Rewriting

y = -2x+12

This is in the form y = mx +b where the slope is -2 and the y intercept is 12

12 is the initial value or when x = 0.  It would be the distance that he needs to cover.  He needs to go from the library to his house.
