The height of a fountain’s water stream can be modeled by a quadratic function. Suppose the water from a jet reaches a maximum h

Grace [21]

Answer:

h(d)= -2d^2 +4d +6

Step-by-step explanation:

Vertex (1,8)

Landing Point (3,0)

Applying the vertex formula, a quadratic equation can be described by its vertex v(x,y) as follows:

$h=a*(d-x)^2 +y$

Since the vertex in this situation is at v (1,8):

$h=a*(d-1)^2 +8$

To solve for 'a', apply the other given point (landing point) into the equation:

$0=a*(3-1)^2 +8\\4a= - 8 \\a=-2$

Expanding the equation yields:

$h=-2*(d-1)^2 +8\\h=-2(d^2 -2d +1) +8\\h= -2d^2 +4d +6\\$

Park Jimin paid $125 to have his hair colored and cut. If he tips his hairdresser 15% of his bill, how much was the tip?

Virty [35]

Money paid by Park Jimin = $125

We need to find the tip , so,

→ 15% of the amount paid

→ $ 125 (15/100)

→ $ 18.75

Hence, the tip is of $ 18.75
