I cannot see the photo shown, but I think you are able to look it up on Google chrome.
The first integral in the table matches the form in the problem, with
... u = x, a = 2, b = 5.
Then the profit function is
... p(x) = 2(15x-4)/(375)√((2+5x)³) - 1501.09
(Without the added constant, the function p(1) evaluates to about 1.09.)
A graph shows the number of sales required for a $12000 profit is about 47 cars.
Sale of 75 cars per week will result in a profit of about p(75) ≈ $42,263.
Fo points (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
(x,y)
(-26,-37)
(-32,-61)
x1=-26
y1=-37
x2=-32
y2=-61
slope=(-61-(-37))/(-32-(-26))=-24/-6=4
slope is 4
Answer:
Yes! The equation, y = 12x + 28 , work.
Step-by-step explanation:
The line passes through points (-1, 16) and (5, 88)
The slope of the line = change in y ÷ change in x
i.e slope = = 12
Taking another point (x ,y) on the line;
Slope is = 12
y - 16 = 12x + 12
y = 12x + 12 + 16
y = 12x + 28
So the equation, y = 12x + 28, work!
