\left(2^8\cdot \:3^{-5}\cdot \:1\right)^{-2}=\left(1\cdot \frac{256}{243}\right)^{-2}=\left(\frac{256}{243}\right)^{-2}=\left(\frac{243}{256}\right)^2

\left(2^8\cdot \:3^{-5}\cdot \:6^0\right)^{-2}\left(\frac{3^{-2}}{2^3}\right)^4\cdot \:2^{28}

=2^{28}\left(\frac{3^{-2}}{2^3}\right)^4\left(3^{-5}\cdot \:2^8\cdot \:1\right)^{-2}

Consider

\left(2^8\cdot \:3^{-5}\cdot \:1\right)^{-2}=\left(1\cdot \frac{256}{243}\right)^{-2}=\left(\frac{243}{256}\right)^2=\frac{243^2}{256^2}

=2^{28}\left(\frac{3^{-2}}{2^3}\right)^4\frac{243^2}{256^2}

=2^{28}\cdot \frac{1}{2^{12}\cdot \:3^8}\cdot \frac{243^2}{256^2}

=\frac{243^2\cdot \:1\cdot \:2^{28}}{256^2\cdot \:3^8\cdot \:2^{12}}

=\frac{2^{16}\cdot \:243^2}{3^8\cdot \:256^2}

=\frac{2^{16}\cdot \:3^{10}}{2^{16}\cdot \:3^8}

=3^2

=9

Given the definitions of f(x) and g(x) below, find the value of (g o f)(0).
Mamont248 [21]

Answer:

its 3

so its

(4x+4)^2-2(4x+4)-5

so first you have to do

(4x+4)(4x+4)

the answer is 16x^2+32x+16

and then you do -2(4x+4) and then you add them so then its

16x^2+32x+16-8x-8-5

and then you just add like terms so its

16x^2+24x+3

and then you insert 0 for x

so the answer is 3

Point A is located at (5, 6) and point B is located at (8, −2) . What are the coordinates of the point that partitions the direc
alekssr [168]

Answer:

(6, 3 1/3)

Step-by-step explanation: Split this problem into x and y parts. In x direction, the length of the AB is (8-5)=3. So 1/3 from A would be 5+1/3(8-5)=6

In y, AB goes from 6 to -2, so the coordinate changes by (-2-6)=-8 units.

1/3 along this ling will be 6 + 1/3 (-2-6)=6-2 2/3=3 1/3

A- Veronica —> v=5+2m
Total —> v+m=32

B- since you already know that to get veronica’s number of stuffed animals, you need to use v=5+2m, you need to substitute it in the total equation. So it’ll be:

(5+2m)+m=32

(5+2m) represents veronica’s stuffed animals
m represents Mariposa’s stuffed animals


C- Mariposa —> 9
Veronica —> 23
