Answer:

Step-by-step explanation:

f(x)=-2x+4\\g(x)=2x^2-2x-8\\(g\circ f)(x)=g(f(x))\\=g(-2x+4)\\=2(-2x+4)^2-2(-2x+4)-8\\=2(4x^2-16x+16)+4x-8-8\\=8x^2+(-32x+4x)+(32-8-8)\\=8x^2-28x+16

Geometry, SEMI-EASY question. I will give brainliest. Just want to double-check.
SashulF [63]

Answer:

Option B

Step-by-step explanation:

Let the point O is the origin.

Then the coordinates of the vertices A,B and C will be,

A → (-12, -8)

B → (-8, 0)

C → (-6, -4)

Rule for the dilation of a point (x, y) by scale factor 'k' about the origin is,

(x, y) → (kx, ky)

By this rule, coordinates of the vertices of the image triangle will be,

If k = \frac{1}{2},

A(-12, -8) → A'(-6, -4)  

B(-8, 0) → B'(-4, 0)

C(-6, -4) → C'(-3, -2)

From the given options,

Option B is the answer.

Emily designed a robot that could climb down steps. She drew a graph to show the results from a test of her new robot. The graph
mamaluj [8]
The answer is A.) \frac{-1}{10}x+15 

To find this answer the first thing we need to do is look at the equation of a straight line: y=mx+b

What I did first was look at b. b represents the y-intercept. By looking at the graph we can tell that the line crosses the y-axis at (0,15), so the y- intercept is 15. So our answer should at least have b=15. Using this we can go ahead and eliminate answers B & C 

Next we look at the slope (m). One way you can figure out slope is using the rise over run method. Since this line has a negative slope our rise should be a negative number. So, the only answer that should be left is A.) \frac{-1}{10}x+15

(3 x 10^6) x (3 x 10^ 5)
OleMash [197]

Answer:

9*10^{11}

Step-by-step explanation:

we have

(3*10^{6})*(3*10^{5})

we know that

(a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)} -----> the bases are multiplied and the exponents are added up

so

in this problem

(3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}

=9*10^{11}
