Answer:
y = 7
Step-by-step explanation:
Use the given ordered pairs to find a and b
Using (0, 7 ), then
7 = a (
= 1 ), thus
a = 7
y = 7
Using (5, 1701 )
1701 = 7 ( divide both sides by 7 )
243 = ( take the fifth root of both sides )
b = = 3 , thus
y = 7
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
