Answer:
At 0.713 second the ball will hit the ground
Step-by-step explanation:
The height of an object t seconds after it is thrown from a height of h feet is modeled by the equation:

The ball is thrown from a point 6 feet above ground with an initial velocity, v, of 30 feet per second, equation becomes:

It is required to find the time when the ball hits the ground. At that point, h(t) =0.
So,

Above is a quadratic equation, the value of time is given by :
t = -0.526 s and t = 0.713 seconds
So, at 0.713 second the ball will hit the ground.
Answer:
The interest is $1512 and the amount is $1519.
Step-by-step explanation:
: Convert interest rate of 7200% per month into a rate per year. Then Convert 3 months into years. Next Find an interest by using the formula, where I interest, P is total principal, i is the rate of interest per year, and t is the total time in years. Lastly, Find an amount by using the formula.
Answer:
72 degrees
Step-by-step explanation:
Because you want subtract both of the number from 180 because triangles angles always have to equal 180 degrees. I hope that helped! :)
