.2 x 150,000 would be the way to find the employee's salary because 20% = .2
Answer:
Try 250 = 70x + 50, or y = 70x + 50.
Step-by-step explanation:
He made 250 total. The variable is how many cars he washes. The y-intercept is 50. Therefore, either 250 = 70x + 50, or y = 70x + 50.
Answer:
Step-by-step explanation:
Domain of a function represents the set of x-values (input values) and y-values (output values) of the function represent the Range of the function.
Given function is,
If Domain (input values) of this function is,
{-12, -6, 3, 15}
Table for the input-output values of this function,
x -6 3 15 -12
y 11 5 -3 15
C(x) should be ;
C(x)=0.9x² - 306x +36,001
Answer:
$9991
Step-by-step explanation:
Given :
C(x)=0.9x^2 - 306x +36,001
To obtain minimum cost :
Cost is minimum when, C'(x) = 0
C'(x) = 2(0.9x) - 306 = 0
C'(x) = 1.8x - 306 = 0
1.8x - 306 = 0
1.8x = 306
x = 306 / 1.8
x = 170
Hence, put x = 170 in C(x)=0.9x²- 306x +36,001 to obtain the
C(170) = 0.9(170^2) - 306(170) + 36001
C(170) = 26010 - 52020 + 36001
= 9991
Minimum unit cost = 9991
