Answer:
3
Step-by-step explanation:
(3/4)x-(5/4)=(1/3)x
(3/4)x-(1/3)x=(5/4)
x((3/4)-(1/3))=(5/4)
(5/12)x=(5/4)
x=(5/4)/(5/12)
x=3
A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola y = 7 − x 2 y=7-x2. what are the dimensions of such a rectangle with the greatest possible area?
Answer:
(0,-4)
Step-by-step explanation:
We need to cancel out the discontinuity in x = 4
In order to do that, factorize the numerator:
5x⁴ - 20x³ = 5x³(x-4)
This way, your function will be:
f(x) = <span>5x³(x-4) / (x-4)
and the two parentheses cancel out, leaving
</span>f(x) = <span>5x³
</span>
which at x = 4 gives:
f(4) = <span>5·4³</span> = 5 · 64 = 320
Therefore K = 320.
Answer:
1 hour
Step-by-step explanation:
It takes 1 hour and 45 minutes to get from 11:30 to 1:15. If you take 45 minutes to have lunch, then that leaves you with 1 hour to shop.
