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
Answer:
16 hours
Step-by-step explanation:
company A $800 plus $16 per hour
company B $720 plus $21 per hour
im going to start with 10 and go from there
company A
16 x 10 = 160
800 + 160 = 960
company B
21 x 10 = 210
720 + 210 = 930
it needs to go up so lets try 15
company A
16 x 15 = 240
800 + 240 = 1040
company B
21 x 15 = 315
720 + 315 = 1035
one more maybe 16
company A
16 x 16 = 256
800 + 256 = 1056
company B
21 x 16 = 336
720 + 336 = 10 56
In y = mx + b form, the slope will be in the m position and the y int will be in the b position.
y = mx + b......slope(m) = -2/3....y int (b) = 4
y = -2/3x + 4
The width of the actual yard is 50 feet wide. Since the scale from the drawing to real life is 1 inch for every 10 feet, simply multiply 1:10 by the same number on both sides to get an equivalent ratio using the given scale. Basically, 1 inch : 10 feet * 5:5 equals 5 inches for every 50 feet.
Alternative:
1 inch = 5 inches
10 feet = ? feet
If you multiply the numerator by 5, you multiply the denominator by five to ensure the ratio and scale are still accurate and equivalent. 10 * 5 = 50.
