When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0 = -(x-2)^2 + 16

(x-2)^2 = 16

x-2 = 16

x-2 = 4

x = 6

This means the ball will hit the ground 6 seconds after Amir threw it.

A retail store is offering a series discount of 10/10 on a dishwasher with a list price of $346. Find the net cost after the ser

lutik1710 [3]

$346/100=$3.46 =1% of $346. So, giving 10% discount we $3.46*90=$311.40

Again, $311.40/100=$3.114, providing, 10% discount we get $3.114*90=$280.26.

The net cost after the series discount is $280.26
