All computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that rep

prohojiy [21]

So the original price is "x".

the discounted price by 10% is P(x) = 0.9x.

the price minus a $150 coupon is C(x) = x - 150.

so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.

C( P(x) ) = P(x) - 150

C( P(x) ) = 0.9x - 150

Tranh dives off a 9 m platform. He reaches a maximum height of 9.2 m after 0.26 s. How long does it take him to reach the water

777dan777 [17]

He will reach the ground after 2.023 seconds.

To start, write a quadratic equation in vertex form with the given information about the vertex.

$y=a(x-2.6)^2+9.2$

All that we need to solve for is a. Plug in the point (0, 9) and you will be able to solve for a and write the complete equation.

Now, just use the quadratic formula and you will get 2.023 seconds for when he hits the ground.
