Find the vertex of the quadratic function:
y=1/2x^2 + 8x – 50
Answer:
definition
The vertex form of a quadratic function is given by
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.
FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form". To avoid confusion, this site will not refer to either as "standard form", but will reference f (x) = a(x - h)2 + k as "vertex form" and will reference f(x) = ax2 + bx + c by its full statement.
When written in "vertex form":
• (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.
• the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).
• the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).
• notice that the h value is subtracted in this form, and that the k value is added.
If the equation is y = 2(x - 1)2 + 5, the value of h is 1, and k is 5.
If the equation is y = 3(x + 4)2 - 6, the value of h is -4, and k is -6.

button To Convert from f (x) = ax2 + bx + c Form to Vertex Form:
Method 1: Completing the Square
To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example.

Answer:
Transitive property
Step-by-step explanation:
Refer to the picture given below;
Answer:
transitive property
Step-by-step explanation:
it not complementary angles because it not 90 degree
it not vertical angles because it doesn't show pair angles formed when two lines intersect.
it not reflexive property because it doesn't shown a number is always equal to itself.
so, for the reason above i think transitive property is the answer.

1) Azalee loves stuffed animals! Initially she had 10 stuffed animals. Her collection continues to grow at a rate of 24% per year. How many stuffed animals will she have in 6 years? Group of answer choices 51 stuffed animals 24 stuffed animals 47 stuffed animals 36 stuffed animals
Answer:
B. 24 stuffed animals
Step-by-step explanation:
Initial amount of animal = 10
If her collection continues to grow at a rate of 24% per year, then increment in number of animal after 1 year will be:
24% of 10
= 0.24×10
= 2.4
Total increment after 6years will be:
= 2.4×6
= 14.4
Total stuffed animal that she will have after 6years = initial amount + increment = 10+14.4
Total stuffed animal that she will have after 6years = 24.4 ≈ 24 stuffed animals

Answer:
[tex]y = \frac{2}{3} x + 12[/tex]
Step-by-step explanation:
[tex]y = - \frac{3}{2} x - 1[/tex]
The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.
Thus, gradient of given line=[tex] - \frac{3}{2} [/tex].
The product of the gradients of perpendicular lines is -1.
(Gradient of line)(-3/2)= -1
Gradient of line
[tex]- 1 \div ( - \frac{3}{2} ) \\ = - 1( - \frac{2}{3} ) \\ = \frac{2}{3}[/tex]
Substitute m=[tex]\frac{2}{3} [/tex] into y=mx+c:
[tex]y = \frac{2}{3} x + c[/tex]
To find the value of c, substitute a pair of coordinates.
When x= -6, y= 8,
[tex]8 = \frac{2}{3} ( - 6) + c \\ \\ 8 = - 4 + c \\ c = 8 + 4 \\ c = 12[/tex]
Thus, the equation of the line is [tex]y = \frac{2}{3} x + 12[/tex].
M is the midpoint of point A (5,4) and point B (15,0)
What is the x- coordinate of M
Answer:

Here (x₁, y₁ ) = A(5, 4) and (x₂, y₂ ) = B(15, 0) , then
M = ( [tex]\frac{5+15}{2}[/tex], [tex]\frac{4+0}{2}[/tex] ) = ( [tex]\frac{20}{2}[/tex], [tex]\frac{4}{2}[/tex] ) = (10, 2 )

Cecil sold vegetables at the farmers market on Saturday and Sunday. On Saturday, he collected twenty $1 bills, six $5 bills, four $10 bills, and five $20 bills. On Sunday, he collected thirty $1 bills, four $5 bills, five $10 bills, and one $20 bill. How much money did Cecil collect in total?
Answer:
$250.00
Step-by-step explanation:
twenty $1 bills- 20 x 1 = 20
six $5 bills- 6 x 5 = 30
four $10 bills- 4 x 10 = 40
five $20 bills- 5 x 20 = 100
thirty $1 bills- 30 x 1 = 30
four $5 bills- 4 x 5 = 20
five $10 bills- 5 x 10 = 50
one $20 bill- 1 x 20 = 20
Add the bold totals together and get the final answer of $250.00
Which are true if figure DEFG is reflected across the x-axis? Check all that apply.
Answer:
1.D(0, 4) → D'(0, –4)
2.E(–2, 0) → E'(–2, 0)
3.The perpendicular distance from G' to the x-axis will equal 2 units.
4.The perpendicular distance from D' to the x-axis will equal 8 units.
5.The orientation will be preserved.
Step-by-step explanation:
D(0, 4) becomes D'(0, –4) and E(–2, 0) becomes E'(–2, 0).
We know that the rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
The coordinate of D(0, 4) becomes D'(0, –4) and coordinate of E(–2, 0) becomes E'(–2, 0).
3.The perpendicular distance from G' to the x-axis is 2 units.
4.The perpendicular distance from D' to the x-axis is 8 units.
Hence D(0, 4) becomes D'(0, –4) and E(–2, 0) becomes E'(–2, 0).

use 3.14 for PI
Answer:
153.86 inches²
Step-by-step explanation:
How do we find the radius of a circle?
The radius of a circle is 1/2 of the diameter, so 14/2 = 7 inchesHow do we find the area of a circle?
We can find the area of a circle by using πr², where r = radius. We're given the radius as 7 inches and pi as 3.14.Solving
[tex]3.14*7^2[/tex] [tex]3.14*49[/tex] [tex]153.86[/tex]Therefore, the answer is 153.86 inches².
Have a lovely rest of your day/night, and good luck with your assignments! ♡
The area of the circle is 153.86 square inches.
We have,
Diameter = 14 inch
Radius= 14/2 = 7 inch
Now, the formula for area of a circle,
Area = π (radius)²
Now we can calculate the area using the radius:
Area = 3.14 x (7 inches)²
Area = 3.14 x 49 square inches
Area ≈ 153.86 square inches
Therefore, the area of the circle is 153.86 square inches.

Since the 2 angles equal 180, and we already know one is 112, we can subtract that. and because it is 2 times a number, we need to get half of whatever that number is, which was 68, and we got 34. this would be the value of y, because when plugged in, 112+2(34)=180.
