The vertex of a parabola is (-1, -8) and the zeros are (-5, 3) Determine the equation of the parabola in standard and factored form
Answer:
Part A
The equation of the parabola in standard form is f(x) = 0.5·x² + x - 7.5
Part B
The equation of the parabola in factored form is f(x) = 0.5·(x + 5)·(x - 3)
Step-by-step explanation:
The coordinates of the vertex of the parabola, (h, k) = (-1, -8)
The zeros of the parabola = -5, 3
Part A
The quadratic equation representing the parabola can be written as follows;
y = a·(x - h)² + k
The standard form of the equation is f(x) = a·x² + b·x + c
k = c - b²/(4·a)
h = -b/(2·a)
c = k + a·h² = -8 + a
From the zeros of the parabola, we have;
f(-5) = a × (-5)² + b×(-5) + c = 25·a - 5·b + c = 0
f(3) = a × (3)² + b×(3) + c = 9·a + 3·b + c = 0
Therefore, we have;
25·a - 5·b + c = 0...(1)
9·a + 3·b + c = 0...(2)
From which we have;
25·a - 5·b + c = 25·a - 5·b - 8 + a = 26·a - 5·b - 8 = 0
9·a + 3·b + c = 9·a + 3·b - 8 + a = 10·a + 3·b - 8 = 0
We then have;
26·a - 5·b = 8...(3)
10·a + 3·b = 8...(4)
Making 'b', the subject of both equations (3) and (4), equating the values, we find the value of 'a' as follows;
From equation (3), we have;
26·a - 5·b = 8
∴ b = (26·a - 8)/5
From equation (4), we have;
10·a + 3·b = 8
∴ b = (8 - 10·a)/3
From b = b, by transitive property, we have;
(26·a - 8)/5 = (8 - 10·a)/3
3 × (26·a - 8) = 5 × (8 - 10·a)
78·a - 24 = 40 - 50·a
∴ 128·a = 64
a = 64/128 = 1/2 = 0.5
a = 0.5
∴ b = (26·a - 8)/5 = (26 × 0.5 - 8)/5 = (13 - 8)/5 = 1
b = 1
c = -8 + a
∴ c = -8 + 0.5 = -7.5
c = -7.5
The equation of the parabola in standard form is therefore presented as follows;
f(x) = 0.5·x² + x - 7.5
Part B
The equation of the parabola in factored form is given as follows;
With the aid of a graphing calculator, we have;
f(x) = 0.5·x² + x - 7.5 = 0.5×(x² + 2·x - 15) = 0.5·(x + 5)·(x - 3)
The equation of the parabola in factored form is f(x) = 0.5·(x + 5)·(x - 3)

At what position on the number line is the red dot located, thank you
Answer:
Root under 39
Step-by-step explanation:
Just multiply the times like 5, 5.25, 5.50, 5.75, 6, 6.25 , 6.50....in such way and calculate...
Answer:
D. [tex]\sqrt{39}[/tex]
Step-by-step explanation:
You don’t even need a calculator for this task.
You can see that the dot is 6.2, but lets just think what number should give us 6 in [tex]\sqrt{x}[/tex], and we know it’s [tex]\sqrt{36}[/tex], but since our dot equal 6.2, we see from our choise that the best answer is [tex]\sqrt{39}[/tex].
Select the expression that has a value of 23.
6 + (9 x 3) ÷ 3 + 8
(6 + 9) + 3 ÷ 3 + 8
6 + 9 x 3 ÷ (3 + 8)
(6 x 9 x 3) ÷ 3 + 8

Richie is solving the equation x^2 – 12x = 28 by completing the square. What number should he add to
both sides of the equation to complete the square? Pleaseee Help
Answer:
Richie should add the number 36 to both sides.
Step-by-step explanation:
To complete the square, you need to divide b by 2, square it, then add it to both sides. In this case, you'd do this:
12/2=6
6^2=36

Step-by-step explanation:
The third side of a triangle can be any value in the range of -
1 ≤ a < 17.
What is a triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique planeGiven are two sides of a triangle as b = 7m and c = 10m.
The sum of two sides of a triangle is always greater than the third side. Mathematically -
a < {b + c}
a < {7 + 10}
a < 17
a ∈ [1, 16]
Therefore, the third side of a triangle can be any value in the range of -
1 ≤ a < 17.

4.) A store is having a sale in which all items are marked 30% off.
4a.) Which equation represents the selling price, s, in dollars, of an item originally
priced p dollars after a markdown of 30%?
a.) s=0.3p
b.) s=0.7p
c.) p=0.35
d.) p=0.75
Answer:
0.70p
Step-by-step explanation:
"30% off" means paying only 70% of the original sales price (subtracting 30% from 100% yields 70%). Next, find the decimal equivalent of 70%:
It is 0.70. Finally, multiply the price p by 0.70: 0.70p (Answer b)
