Ooooppppppp— homie not gettin nun at home I see
Fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.
Any polynomial's graph cannot have two simultaneous maxima, so they must contain a minima between them. Thus, the total number of turning points of the graph is 3. Generally, when plotting a polynomial, the number of turning points is:
n = d -1; where d is the degree of the polynomial and n is the number of turning points. Thus, this function's degree must be at least 4. The answer is b.
The percent markup would be 40%. 10+40%=14
Hope this helps!
Can u plz mark me as brainliest? I really need it!
2)
(-3, 3) (2,0)
slope = (3-0)/(-3-2) = -3/5
3)
y = 3
so slope = 0
