Answer:
- 3.9 hours
- 90 mph
Step-by-step explanation:
<h3>1.</h3>
The sum of the rates of painting, in fences per hour, is ...
1/9 + 1/7 = (9+7)/63 . . . . fences per hour
The total rate in hours per fence is the inverse of that:
63/16 = 3 15/16 ≈ 3.9 . . . hours to paint the fence
__
<h3>2.</h3>
The relevant relationship is ...
distance = speed × time
Let t represent Tom's speed in miles per hour. Then George's speed is (t-36). They both have traveled the same total distance at the point where Tom catches up.
(2+3)(t-36) = 3t
2t = 180 . . . . . . . add 180-3t
t = 90 . . . . . . divide by 2
Tom's average speed is 90 miles per hour.
Answer:
There are 5 turning points at x = -3, -1.11, 0, 1.44 and 4.
Step-by-step explanation:
The product rule for 3 terms is
F' (x) = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
F(x) = x^2(x - 4)^7 (x + 3)^6
F' (x) = 2x(x-4)^7(x+3)^6 + x^2 7(x - 4)^6 (x + 3)^6 + x^2(x-4)^7 6(x+3)^5 = 0 at the turning points.
That is some equation!!
By observation, 3 roots are x = 0 , x = 4 and x = -3 so there are turning points at these values of x.
I'll use software to graph it to find any more real solutions - they are -1.11 and 1.44 to nearest hundredth.
