Part A- The vertex form of the question of horizontal parabola is given x=1/4p(y-k)^2+h, where (h, k) is the vertex of the parabola and the absolute value of p is the distance from vertex to focus, which is also the distance from the vertex to the directrix. You will use GeoGebra to create a horizontal parabola and write the vertex form of its equation. Open GeoGebra and complete each step below. Mark the focus of the parabola you are going to create at F(-5,2). Draw a vertical line that is 8 units to the right of the focus. This line will be the directrix of your parabola. What is the equation of the line?

step-by-step explanation:

ask goog great chance of finding the solution there

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

you need to give us more information since we can't answer

h= 12 inches
