f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Step-by-step explanation:
interchanging the variables
x = 5y^2 + 10
5y^2 +10 = x
5y^2 = x - 10
dividing by 5
5y^2/5 = x/5 + -10/5
y^2 = x/5 + - 10/5
y^2 = x/5 - 2
y = 5 (x-10) 0/5 (sq.rt)
g(5x^2 + 10) = 5x/5
g(5x^2 + 10) = x
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Use long multiplication to evaluate.

<u>Multiple Regression Analysis is the technique used o see if there is any impact of price point, color, or the interaction</u>
<u />
Step-by-step explanation:
- Multiple regression is a statistical technique which is used to predict the value of a variable based on the values of the two or more variables.
- In the above example we want to predict the Purchase value depending upon the value of the price points and the value of the product colors.
Answer:
$70.
Step-by-step explanation:
Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:
(19 x 15) + X = 1615
285 + X = 1615
X = 1330
1330/19 = 70
Thus, the fixed amount Neda receives for each television is $70.
