Consider a trapezoid GJKF with:
GH=JH (hypothesis)
FL=KL (hypothesis)
so HL is the median of trapezoid GJKF
so: HL=1/2(2.5+1.2)=1.85
Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages
It will be b im ask my teacher
It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954
Answer:
Yes, see below.
Step-by-step explanation:
Convert the equation to vertex form to find the maximum height:
h = -16t2 + 64t + 5
= -16(t^2 - 4t) + 5
= -16 [(t - 2)^2 - 4] + 5
= -16( t - 2)^2 + 64 + 6
= -16(t - 2)^2 + 69.
So the maximum height the rock reaches is 69 feet.
This height is reached at 2 time seconds.
