The tax rounded to the nearest penny would be $2.19 because you would round the 5 up.

1. (f+g)(x) = f(x) +g(x)
.. = (x^2-36) +(x^3+2x^2-10)
.. = x^3 +3x^2 -46

2. (f•g)(x) = f(x)•g(x)
.. = (x^4-9)•(x^3+9)
.. = x^7 +9x^4 -9x^3 -81

3. (f-g)(x) = f(x) -g(x)
.. = (x^3-2x^2+12x-6) -(4x^2-6x+4)
.. = x^3 -6x^2 +18x -10

In two or more complete sentences, compare the number of x-intercepts in the graph of f(t) = 12 to the number of x-

alina1380 [7]

Answer:

Both functions have one x-intercept each.

Step-by-step explanation:

The first function is

$f(t )= {t}^{2}$

This is a parabola with vertices at the origin and has one x-intercept at t=0.

The transformed function is

$g(t) = {(t + 3)}^{2}$

The function g(t) is obtained by shifting the graph of f(t) to the left by 3 units.

This graph also has one x-intercept at x=-3.

Therefore both functions has the same number of x-intercepts

A coat has been marked down 20% to $26.40 what was it's original value?

Gemiola [76]

20% is equal to 0.2
0.2 times 26.40 is equal to 5.28
26.40 minus 5.28 is equal to 21.12

Is the answer 3, 4, 5, or 6? need answer asap please! :)

Don't touch the center. It is already even.
Start anywhere by connecting a dotted line from one vertex to the next. To keep things so we know what we are talking about, go clockwise. Now you have 2 points that are Eulerized that were not before.

Skip and edge and do the same thing to the next two vertices. Those two become eulerized. Skip an edge and do the last 2.

Let's try to describe this better. Start at any vertex and number them 1 to 6 clockwise.
Join 1 to 2
Join 3 to 4
Join 5 to 6

I think 3 is the minimum.
3 <<<< answer
