3 0

Step-by-step explanation:

  • (8x-38°)=90° {because of being vertically opposite angles}
  • 8x-38°=90°
  • 8x=90°-38°
  • 8x=52°
  • x=52°/8
  • x=6.5°

  • z°+90°=180° {being linear pair}
  • z°=180°-90°
  • z°=90°

match the steps to find the equation of the parabola with focus (-1, -8.75) and directrix y = - 9.25.
choli [55]

Answer:

The matched options to the given problem is below:

Step1: Choose a point on the parabola

Step2: Find the distance from the focus to the point on the parabola.

Step3: Use (x, y).

Find the distance from the point on the parabola to the directrix.

Step4: Set the distance from focus to the point equal to the distance from directrix to the point.

Step5: Square both sides and simplify.

Step6: Write the equation of the parabola.

Step by step Explanation:

Given that the focus (-1,2) and directrix x=5

To find the equation of the parabola:

By using focus directrix property of parabola

Let S be a point and d be line

focus (-1,2) and directrix x=5 respectively

If P is any point on the parabola then p is equidistant from S and d

Focus S=(-1,2), d:x-5=0]

Select the choice that translates the following verbal phrase correctly to algebra:
maria [59]

w + 15 since increased by 15 means add on

12y + 11 since product of 12 and y means multiply 12 and y = 12y

one half n - 16 since one half of n and decreased by 1 6 , subtract 16

2b - 6 since Corinne is 6 years younger represented by b - 6

sum of their ages = b + b - 6 = 2b - 6

9h + 40

$ 9 per hour for h hours = 9 × h = 9h plus the $ 40 from carpool
