What is the equation of the parabola with vertex (-5, 4) and focus (-2, 4)?

Step-by-step explanation:

In this problem we have that

The vertex and the focus has the same y-coordinate, therefore, is a horizontal parabola

The equation of a horizontal parabola is of the form

where

(h,k) is the vertex

The coordinates of the focus are equal to

we have in this problem

substitute

so

Find the value of a

The equation of the horizontal parabola is equal to

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
