A ball is dropped from a ledge, and its height is given by the formula ℎ = −16t + 15t + 1050. How long will it take to hit the ground?

1050 s

Step-by-step explanation:

When the ball hits the ground, height will be zero hence the time taken, considering the equation given as ℎ = −16t + 15t + 1050.

Substituting 0 for h then

0 = −16t + 15t + 1050

-t+1050=0

t=1050

If the formula was in terms of seconds then the time is 1050 seconds

answer: b.36 feet

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
