Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a horizontal quadratic function, of vertex (h,k), is given by:
(y - k)^2 = 4p(x - h)
The directrix is given by:
x = h - p.
In this problem, the equation is given by:
(y - 2)² = 0.25(x - 5).
Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:
x = h - p = 5 - 0.0625 = 4.9375.

Answer:
She missed her goal, because she made less than $75 on coffee today.
Step-by-step explanation:
Gabriela, did not meet her goal because she only mad 72$ today
if you do
80 cents times 90 cups you only get 72$
meaning that she was 3$ short from meeting her goal.
.80 * 90
Answer:
- 525 into a percent is 525%. Or 5.25.
Step-by-step explanation:
<u>It's pretty simple.</u>
<u>All you have to do is this:</u>
All we did was put a percentage sign at the end at the number.
If you want to do it the hard way,
<u>Do this:</u>
What we did was move a decimal point 2 spaces to the left.
This also counts as a percentage.
Use TrianCal to draw a triangle with phi as Great Piramid (minimum perimeter given 2 equal heights) = maximun stability.
NOTE: Phi=(1+√5)/2≈1.62 and acos(1/Phi)≈51.83º
Answer:
34.12
Step-by-step explanation:
9.99x4 is 39.96
39.96x20%=7.99
39.96-7.99= 31.97
31.97x6.75%= 2.16
2.16+31.97= $34.12
