The quadratic function which has zeros −3 and 5 and contains the point (4, 14) is 2x²+4x+30 and the vertex points are (-1,28).
What is a quadratic equation?A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.
The standard form of the quadratic equation is,
ax²+bx+c=0
Here,(a,b, c) is the real numbers and (x) is the variable.
A quadratic function has zeros −3 and 5 and contains the point (4, 14). The factored form of quadratic equation is,
f(x)=a(x-z₁)(x-z₂)
Here, z₁ and z₂ are the zeros. Thus,
f(x)=a(x-z₁)(x-z₂)
f(x)=a(x-(-3))(x-5)
f(x)=a(x+3)(x-5)
This equation contains the point (4,14). Thus,
14=a(4+3)(4-5)
14=a(7)(-1)
a=14/-7
a=-2
Put the value in above equation and solve it further:
f(x)=-2(x+3)(x-5)
f(x)=-2(x²-5x+3x-15)
f(x)=-2x²-4x-30
Change the sign,
f(x)=2x²+4x+30
The equation of the quadratic function in standard form is,
f(x)=2(x+1)²+28
Thus, the vertex point are -1 and 28. Similarly, the section equation which contains the point (1, −48) can be solved.
Hence, the quadratic function which has zeros −3 and 5 and contains the point (4, 14) is 2x²+4x+30 and the vertex points are (-1,28).

Adrian's computer cost 20% less than Jocelyn's computer. Adrian's computer cost $640. Adrian's computer cost 15% more than Corbin's computer. (50 Points)
Answer:
640 = .8j
640 = 1.15c
Step-by-step explanation:
Let j = cost of Jocelyn's computer
c = cost of Corbin's computer
We know that Adrian's computer costs $640.
Since Adrian's computer costs 20% less than Jocelyn's computer, the cost of Adrian's computer is 80% of (.8 times)the cost of Jocelyn's computer, so 640 = .8j
Since Adrian's computer costs 15% more than Corbin's computer, the cost of Adrian's computer is 115% of (1.15 times) the cost of Corbin's computer, so 640 = 1.15c
Answer:
640 = .8j
640 = 1.15c

Answer: D. "Number graph ranging from negative three to three on the x axis and negative two to four on the y axis. A line is drawn on the graph that passes through the points (negative one, zero) and (zero, four)."
Step-by-step explanation:
We know that our graph passes through two given sets of points, therefore we can plug in those points to find the correct answer.
Let's test it with choice A. It gives us the points (0,-6) and (3,0). We can plug these into the equation to see if it is true. y-4 = 2(x+1) becomes
-6-4 = 2(3+1), or -10 = 8 which is not true, so we can eliminate it.
Choice B gives us (0,-4) and (1,0) -4-4 = 2(0+1) or -8 = 2, this one is wrong.
Choice C gives us (-1,0), so 0-4 = 2(-1+1) or -4 = 0, this one is also wrong.
Choice D gives us (-3,0) so 0-4 = 2(-3+1) or -4 = -4. This is the only option which has a correct solution, and therefore it is your answer.

Welcome to concept of Inscribed Angle theorem
In the diagram shown above, the inscribed angle m∠SUT intercepts the diameter ST.
Then,
m∠SUT = 90°
In Δ SUT,
m∠S + m∠U + m∠T = 180°
Substitute.
m∠S + 90° + 43° = 180°
m∠S + 133° = 180°
Subtract 133° from each side.
m∠S = 47°
m∠UST = 47°
By Inscribed Angle Theorem,
m∠arc UT = 2 ⋅ m∠UST
Substitute.
(9x - 14)° = 2 ⋅ 47°
(9x - 14)° = 94°
9x - 14 = 94
Add 14 to each side.
9x = 108
Divide each side by 9
x = 12
Hence, we get as x = 12°

The Mean Absolute Deviation for the following data: 6, 1, 3, 8, 5, 11, 1, 5 is 2.5
What is mean absolute deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean.

( There is also another method to solve this but I choose this one cause this one is easy to understand....)
A) find the value of x
B) find the value of y
Answer:
a) x = 9.
b) y = 61.
Step-by-step explanation:
As the 2 weighing scales balance:
4 + 4x = 31 + x
3x = 31 - 4 = 27
x = 9.
Also 4 + 4x + x + 31 = y + 2x + 1
Substituting for x:
4 + 4(9) + 9 + 31 = y + 2(9) + 1
80 = y + 19
y = 80 - 19 = 61.
Answer:
x = 9
y = 61
Step-by-step explanation:
The main scales are balanced.
The left side of the main scales comprises another scale, which is also balanced.
From this and the values given, we can construct two equations.
Equation 1
Balancing the scales on the left of the main scales:
⇒ 4 + 4x = 31 + x
Solving this for x:
⇒ 4 + 4x - 4 = 31 + x - 4
⇒ 4x = 27 + x
⇒ 4x - x = 27 + x - x
⇒ 3x = 27
⇒ 3x ÷ 3 = 27 ÷ 3
⇒ x = 9
Equation 2
Balancing the main scales:
4 + 4x + 31 + x = y + 1 + 2x
Rearranging to make y the subject:
⇒ 5x + 35 = y + 1 + 2x
⇒ 5x + 35 - 1 = y + 1 + 2x - 1
⇒ 5x + 34 = y + 2x
⇒ 5x + 34 - 2x = y + 2x - 2x
⇒ 3x + 34 = y
Substituting the found value of x (from Equation 1) and solving for y:
⇒ y = 3(9) + 34
⇒ y = 27 + 34
⇒ y = 61
Therefore:
x = 9y = 61N

Step-by-step explanation:
Finding volume :
V = LWH/2V = 1/2 x 14 x 8 x 8V = 7 x 64V = 448 cm³Answer: 448 cm³
Step-by-step explanation:
Volume of a triangle prism can be found with;
V = [tex]\frac{1}{2}[/tex] * W * L * H
V = [tex]\frac{1}{2}[/tex] * W * L * H
V = [tex]\frac{1}{2}[/tex] * 8 cm * 14 cm * 8 cm
V = [tex]\frac{1}{2}[/tex] * 8 cm * 14 cm * 8 cm
V = 448 cm³

The general form of a circle is given as x^2+y^2+4x - 12y + 4 = 0. A) What are the coordinates of the center of the circle? B) What is the length of the radius of the circle? ( Please Do Not Repost Someone Else's Answers On Brainly Or Any Other Websites Please If So You'll Be Reported). Will Mark Brainliest if answered correctly and please be honest .
Answer:
center = (-2, 6)
radius = 6
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.
Given equation:
[tex]x^2+y^2+4x-12y+4=0[/tex]
Collect like terms and subtract 4 from both sides:
[tex]\implies x^2+4x+y^2-12y=-4[/tex]
Complete the square for both variables by adding the square of half of the coefficient of [tex]x[/tex] and [tex]y[/tex] to both sides:
[tex]\implies x^2+4x+\left(\dfrac{4}{2}\right)^2+y^2-12y+\left(\dfrac{-12}{2}\right)^2=-4+\left(\dfrac{4}{2}\right)^2+\left(\dfrac{-12}{2}\right)^2[/tex]
[tex]\implies x^2+4x+4+y^2-12y+36=-4+4+36[/tex]
Factor both variables:
[tex]\implies (x+2)^2+(y-6)^2=36[/tex]
Therefore:
center = (-2, 6)radius = √36 = 6Read the following actions and decide if they are risks or costs.

The cost in dollars of making x items is given by the function C(x) = 10x + 900. The fixed cost is 900 dollars. C(25 ) = $1150. The Range is 250.
What is a function?The function is a type of relation, or rule, that maps one input to specific single output.
The cost in dollars of making x items is given by the function
C(x) = 10x + 900
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
The fixed cost
C(0) = 10(0) + 900
= 0 + 900
= $900
b. What is the cost of making 25 items?
C(25) = 10(25) + 900
= 250 + 900
= $1150
Therefore, C(25 ) = $1150
c. Suppose the maximum cost allowed is $1900. What are the domain and range of the cost function, C(x)?
The domain is the set of values for which the given function is defined.
Range = Maximum value of the data set - Minimum value of the dataset
Range = C(25 ) - C(0)
