Answer:
112 ft²
Step-by-step explanation:
The shaded area is the difference of the areas of the outside rectangle and the inside rectangle. Each of those areas is the product of the rectangle dimensions.
shaded area = (14')(12') -(8')(7') = (14')(12') -(14')(4') = (14')(12' -4')
shaded area = 112 ft²
Answer:
5 sqrt(11)
Step-by-step explanation:
sqrt(99) + sqrt(44)
sqrt(9*11) + sqrt(4*11)
sqrt(9)sqrt(11) + sqrt( 4) sqrt(11)
3sqrt(11) + 2 sqrt(11)
5 sqrt(11)
The given equation is -3x²+240x-800
The maximum of the function is given when
where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have
Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
43+t or t+43 more than gives you the clue to add
Answer:
n = 12.546
Step-by-step explanation:
to find the value of n we need to transpose
n ÷ 102 = 0.123
n = 0.123 × 102
n = 12.546
