Answer:
1. x=11
Step-by-step explanation:
2x+5=27
Subtract 5 from both sides
2x=22
Divide 2 from both sides
x=11
7 - 3 = 4....so there is a $ 4 profit for every unit sold
4x = 3600
x = 3600/4
x = 900....so 900 units have to be sold to earn a profit of $ 3600
8 divided by 1/4 (25%) is 2. Therefor, it would be 10 meters.
Answer:Ok, we have:
d(t) = 3*t^2 + 5*t - 2.
The first interval is:
(2, 3)
and remember that, for an interval (a,b), the difference quotient is:
D = (f(b) - f(a))/(b -a)
Then in this first interval we have:
So the average rate of change in (2,3) is 20.
now, in (2, 2.5) we have:
So here the rate of change is 9.25
And in the interval (2, 2.1) we have:
So in this interval the rate of change is 1.73
