A soccer ball is kicked from the ground with an initial upward velocity of
90 feet per second. The equation h = -1622 + 90t gives the height h of the
ball after t seconds.

b. How many seconds wil it take for the ball to reach the ground?

yes

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

step-by-step explanation:

this is a parabola.
