Please discuss the relationship between the value of "a" in a quadratic function [y = a(x - h)2 + k or y = ax2 + bx + c] and the distance the focus is from the vertex. Please give examples to support your conclusion.
Please Help!
Answer:
The given equations are;
y = a·(x - h)² + k or y = a·x² + b·x + c
We have;
(x - h)² = 4·p·(y - k),
Where;
(h, k) are the x, and y coordinates of the vertex
p = The distance from the focus to vertex distance;
Comparing, we have;
y - k = a·(x - h)²
(y - k)/a = (x - h)²
(x - h)² = 4·p·(y - k)
4·p·(y - k) = (x - h)²
∴ 4·p = 1/a
p = 1/(4·a)
Therefore, the focus to vertex distance inversely proportional to the value of a
The distance of every point on the parabola is equidistant from the directrix and the focus
Therefore, the equation of the directrix is y = k - p
For example, we have;
y = 2·x² + 3·x + 1
h = -b/2a = -3/4
k = (4ac - b²)/4a = (4×2×1 - 3²)/(4×2) = -1/8
The coordinate of the focus is (h, k + p) = (-3/4, -1/8 + 1/8) = (-3/4, 0)
The directrix, y = k - p = -1/8 - 1/8 = -1/4
For a point x = 2, we have, y = 2·2² + 3·2 + 1 = 15
The coordinate of the point is (2, 15)
The distance of the point from the directrix = 15 - (-1/4) = 15 + 1/4 = 15.25
The distance of the point from the focus is √((2 - (-3/4))² + (15 - 0)²) = 15.25
Therefore, all points on the parabola have equal distances from the focus and the directrix

Stephanie is giving a presentation to a new client. It took her 1713 minutes to finish a 13-slide presentation. She took the same amount of time on each slide. How long did she spend on each slide?
Answer:
Time taken per slides = 131.77 minutes.
Step-by-step explanation:
Given the following data;
Total time, t = 1713 mins
Number of slides, n = 13
To find the amount of time spent on each slides;
Time taken per slides = t/n
Substituting into the equation, we have;
Time taken per slides = 1713/13
Time taken per slides = 131.77 minutes.
Therefore, the amount of time Stephanie spent on each slide is 131.77 minutes.
It took Stephanie about 1 minute to finish each slide of the 13-slide presentation.
EquationEquation is used to show the relationship between two or more numbers and variables.
Le x represent the amount of time spent on each slide.
Given that she spent 13 minutes to finish a 13-slide presentation. Therefore:
13x = 13Divide through by 13:
13x/13 = 13/13x = 1It took Stephanie about 1 minute to finish each slide of the 13-slide presentation.

Make Sense and Persevere Paxton, a summer camp counselor, has a budget of $300 to spend on caps and T-shirts for a summer camp.
plz help this is due soon!!!
Answer:
9 shirts and 10 caps
Step-by-step explanation:
Buying one t shirt costs 20 dollars, and one cap would cost 12 dollars. If Paxton bought one cap and one shirt, that would cost 32 dollars. If we multiply that by 9, we get 288. So Paxton can buy 9 shirts and 9 caps with 288 dollars. Paxton has 12 dollars left, so Paxton can buy one more cap to entirely spend the budget.

Answer:
x^3−2x2+4x+3=x2−5x+15+−41x+3
Step-by-step explanation:
1.Divide the leading term of the dividend by the leading term of the divisor: x3x=x2.
Write down the calculated result in the upper part of the table.
Multiply it by the divisor: x2(x+3)=x3+3x2.
Subtract the dividend from the obtained result: (x3−2x2+4)−(x3+3x2)=−5x2+4.
2.Divide the leading term of the obtained remainder by the leading term of the divisor: −5x2x=−5x.
Write down the calculated result in the upper part of the table.
Multiply it by the divisor: −5x(x+3)=−5x2−15x.
Subtract the remainder from the obtained result: (−5x2+4)−(−5x2−15x)=15x
3.Divide the leading term of the obtained remainder by the leading term of the divisor: 15xx=15.
Write down the calculated result in the upper part of the table.
Multiply it by the divisor: 15(x+3)=15x+45.
Subtract the remainder from the obtained result: (15x+4)−(15x+45)=−41.
