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 
You did not provide any question. I will give general advice.
Pythagorean Theorem: a² + b² = c²
If you know two sides, you know ll three sides.
A house sits in the shade.
The house is 18 feet tall. The shadow is 24 feet long. What is the hypotenuse of this triangle?
We know a and b here! a=18, b=24.
18 * 18 = 324.
24 * 24 = 576.
324+576 = 900
The square root of 900 is what will be your answer:
18*18 + 24*24 = 30*30.
I hope this helps!
Answer:
(x+3)² + (y+4)²=25
Step-by-step explanation:
The question is on equation of a circle
The distance formula is given by;
√(x-h)²+ (y-k)²=r
The standard equation of circle is given as ;
(x-h)²+ (y-k)²=r²
The equation of this circle with center (-3, -4) and radius 5 will be;
(x--3)² + (y--4)²=5²
(x+3)² + (y+4)²=25
