Answer:

y = -1/4(x +4)² +4

Step-by-step explanation:

The equation of a parabola with focus (a, b) and directrix y=d can be written using the form ...

y = 1/(2(b-d))(x -a)² +(b+d)/2

<h3>Application</h3>

We are given (a, b) = (-4, 3) and d=5. Using these values in the above form gives the equation ...

y = 1/(2(3-5))(x -(-4))² +(3+5)/2

y = -1/4(x +4)² +4

Ian bought a discounted item for $50, if it was originally $75. What was the discount rate ? round to the nearest percent

kogti [31]

Answer:

Discount rate=33%

Step-by-step explanation:

Step 1

Determine the discounted amount as shown;

A=I-F

where;

A=discounted amount

I=initial price/original price

F=final price after discount

In our case;

A=unknown

I=$75

F=$50

replacing;

A=(75-50)=25

The discounted amount=$25

Step 2

Determine the discount rate using the formula;

Discount rate=(discount amount/original amount)×100

Discount rate=(25/75)×100=33.33%

Discount rate=33%
