Answer:
The value of (gof)(9)=54
Step-by-step explanation:
We are given:
[tex]f(x) = -2x + 14\\g(x) = 2x^2 - 6x - 2[/tex]
We need to find (gof)(9).
To find (gof)(9) first we will find g(f(x)) and then put x=9
Finding g(f(x))
By putting value of f(x) into g(x) i.e
[tex]g(f(x))=2(-2x+14)^2-6(-2x+14)-2[/tex]
Now putting x=9
[tex]g(f(9))=2(-2(9)+14)^2-6(-2(9)+14)-2\\g(f(9))=2(-18+14)^2-6(-18+14)-2\\g(f(9))=2(-4)^2-6(-4)-2\\g(f(9))=2(16)+24-2\\g(f(9))=32+24-2\\g(f(9))=54[/tex]
so, the value of (gof)(9)=54

Use the function f(x)= - 4^x-1 - 2 to answer the questions below.
1.) State the equation for the asymptote.
2.)What is the range?
3.)What is the domain?
4.) Finally which axis is f(x) reflected over and what caused the reflection?
Answer:
See below for answers and explanations
Step-by-step explanation:
I assume the function you wrote was [tex]f(x)=-4^{x-1}-2[/tex]
1) The equation for the horizontal asymptote is y=-2 since a function of the form f(x) = a(b^x) + c always has a horizontal asymptote at y = c, so c=-2, therefore the horizontal asymptote equation is y=-2
2) The range is (-∞,-2) since any real value of y that is less than -2 but doesn't equal -2 (since it's not included) will be a solution.
3) The domain is (-∞,∞) since any real value of x will be a solution.
4) The axis that f(x) is reflected over is the x-axis because when you negate a base in an exponential function, that will occur.

$24 shirt; 6% tax what is the answer please
The tax amount on shirt whose Selling Price is $24 at a tax rate of 6% is $1.44.
What is Tax?
A tax is a financial charge imposed on a taxpayer by a governmental organization in order to fund government spending and public expenditures.
Given is the selling price of shirt as $24. The tax rate is 6%.
Selling price of shirt [S.P.] = $24
Tax rate [R%] = 6%
Therefore, the tax amount = T[A] will be -
T[A] = $(S.P x R/100)
T[A] = $(24 x 6/100)
T[A] = $(24 X 0.06)
T[A] = $1.44
Therefore, the tax amount on shirt whose Selling Price is $24 at a tax rate of 6% is $1.44.

Answer:
[tex] m\angle 1 = 115\degree \\\\
m\angle 2= 130\degree \\\\
m\angle 6= 60\degree \\\\[/tex]
Step-by-step explanation:
[tex] m\angle 1 = m \angle 5\\(corresponding \: \angle s) \\\\
\because m\angle 5 = 115\degree \\
\therefore m\angle 1 = 115\degree \\\\
m\angle 2 = m \angle 7\\(exterior \: alternate \: \angle s) \\\\
\because m\angle 7 = 130\degree \\
\therefore m\angle 2= 130\degree \\\\
m\angle 4 + m\angle 5= 180\degree\\\\
6y\degree + (13y - 10)\degree = 180\degree\\\\
(19y - 10)\degree = 180\degree\\\\

Charles deposited $12,000 in the bank. He withdrew $5,000 from his account after one year. If he receives a total amount of $9,340 after 3 years, find the rate of simple interest.
*SHOW WORK AS SIMPLE AS POSSIBLE*
Answer:
9%
Step-by-step explanation:
12000:
5000 for 1 year
7000 for 3 years
Total interest earned:
9340 - 7000 = 2340
Let x be the irate of simple interst
(5000 x) + (7000(3x)) = 2340
26000x = 2340
x = 0.09
0.09 × 100 = 9%
