Answer:
66 coolers
Step-by-step explanation:
C = 0.005x² - 0.3x + 17
When C = $19
19 = 0.005x² - 0.3x + 17
19 - 17 = 0.005x² - 0.3x
2 = 0.005x² - 0.3x
0.005x² - 0.3x - 2 = 0
x = -b ± √b² - 4ac / 2a
= -(-0.3) ± √-0.3² - 4*0.005*-2 / 2*0.005
= 0.3 ± √ 0.09 - (-0.04) / 0.01
= 0.3 ± √ 0.09 + 0.04 / 0.01
= 0.3 ± √ 0.13 / 0.01
= 0.3/0.01 ± √0.13/0.01
= 30 ± 0.36/0.01
x = 30 ± 36
x = 30 + 36 or 30 - 36
x = 66 or -6
Number of coolers can not be negative
Therefore, number of coolers produced when the cost is $19
is 66 coolers
Answer:
+ 6x + 9 ...so x2 + 6x + 9 is a perfect square trinomial. ... The first term, 16x2, is the square of 4x, and the last term, 36, is the square of 6. (4x)2 – 48x + 62.
Step-by-step explanation:
The slope of the given line is -4/3. the slope of any perpendicular line is the negative reciprocals, or 3/4
5/48
3/16
0.5
0.75
This is listen in least to greatest...
The answer is: " 10,000 cm " .
_________________________________________________
Note: 100 cm = 1 m (exact measurement); in which:
"cm" = centimeter(s) ;
"m" = meter(s) ;
_________________________________________________
100 m = ? cm ?
100 m * (100 cm / 1 m) = __?__ cm ;
The units of "m" cancel out; and we have:
(100)* (100 cm) = 10,000 cm .
