Answer:
Step-by-step explanation:
The formula you wrote has the fraction the other way around. You can find that the range of a projectile is in reality approximated by the equation , where we will use ft for distances.
From the given equation we have then , which means since the arcsin is the inverse function of the sin.
Since we have x = 170 ft and v = 85 ft/s, we can substitute these values from the equation written, and we will have , and from now on we have just to use a calculator, obtaining
Answer:
area=432
Step-by-step explanation:
use the Pythagoras theory now that you know the width and you'll get the length and the width then you multiply both of them hope it helps you.
We see that the total legnth is 9 and 5/8 inches
each piece is 1 and 3/8 inches long
there are 7 pieces
a board that is 9 and 5/8 inches total legnth is cut into pieces that measure 1 and 3/8 inches is cut into 7 pices
not A, should be cut into 7 pices, not 9 and 5/8
not B because the board is 9 and 5/8 long
the answer is C
