Answer:
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.
Step-by-step explanation:
Statement is incorrect. Correct form is presented below:
<em>The height </em>
<em> of an ball that is thrown straight upward from an initial position 3 feet off the ground with initial velocity of 90 feet per second is given by equation </em>
<em>, where </em>
<em> is time in seconds. After how many seconds will the ball be 84 feet above the ground. </em>
We equalize the kinematic formula to 84 feet and solve the resulting second-order polynomial by Quadratic Formula to determine the instants associated with such height:
(1)
By Quadratic Formula:
, 
The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.
Answer:
$2072
Step-by-step explanation:
Note that:
1 year = 12 months
Hence:
1 year = 12 months
3 years = x months
Cross Multiply
x = 3 × 12
x = 36 months
She makes a down payment of $200 and monthly payments of $52 each for three years.
Her total cost is represented by the expression
= $200 + $52 × m
Where m = number of monthly payments.
$200 + $52 × 36
= $200 + $1872
= $ 2072
