Answer:
y = [tex]\frac{4}{3}[/tex][tex]x[/tex] [tex]-7[/tex]
Step-by-step explanation:
Use the points (9, 5) and (6, 1) to identify the slope of the graph
[tex]m[/tex] = [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
m = [tex]\frac{1-5}{6-9}[/tex]
m = [tex]\frac{-4}{-3}[/tex]
m = [tex]\frac{4}{3}[/tex]

See below...
Step-by-step explanation:
Zeros of the function: [tex]f(x)=(x-8)(x+2)[/tex]
The zeros are 8 and -2
The coordinates of the vertex: [tex]f(x)=(x-3)^2-25[/tex]
The vertex is the point (3, -25)
The y-intercept: [tex]f(x)=x^2-6x-16[/tex]
The y-intercept is -16
The axis of symmetry: [tex]f(x)=(x-3)^2-25[/tex]

A. [tex]y=\frac{1}{8}x^2[/tex]
B. [tex]y=\frac{1}{3}x^2[/tex]
C. y = –2x2
D. y = –3x2
Answer:
D. y = –3x2
Step-by-step explanation:
Answer:
y = -3x^2
Step-by-step explanation:
A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.

Carter needs to wrap seven presents. He lays the ribbon out flat and says that I'll have just enough pieces if I make six equally spaced cuts, I can use one piece for each package. And I won't have any pieces left over. Does he have enough pieces to wrap all the presents?
Answer:
Yes, he has enough pieces to wrap the present
Step-by-step explanation:
Given
[tex]Presents = 7[/tex]
[tex]Cuts = 6[/tex]
Required
Is there enough pieces to wrap all presents
As a general rule;
When a piece is cut in 1 place, you get 2 pieces
When a piece is cut in 2 places, you get 3 pieces
When a piece is cut in 3 place, you get 4 pieces
This implies that:
n cuts gives n + 1 pieces
i.e.
[tex]n \to n + 1[/tex]
So, we have:
[tex]6\ cuts \to (6 + 1) pieces[/tex]
[tex]6\ cuts \to 7\ pieces[/tex]
Hence, there are enough pieces.

The second doughnut glazing machine can glare 78 dozen doughnuts in
2 hours
Based on this rate, what is the total number of hours it will take the second
machine tolar 135 doren doughnuts Show or explain how you got you
answer
Answer:
t = 3.46 hours, or 3 hours 28 minutes
Step-by-step explanation:
78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.
Donuts produced as a function of time: D(t), where t is the number of hours the macine runs.
Set D(t) = 135 dozen = (39 dozen/hr)t.
Solving this equation for t, we get:
t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes
There are 345 rows of flowers in a garden. Each row contains 48 flowers. Find the estimated number of flowers in the garden.
Please give the statements and explanation
Answer:
total no. of rows in garden= 345 each row contains= 48 flowers
total no. of flowers in the garden= 345*48=16560
Answer:
16,560
Step-by-step explanation:
No of rows = 345
No. of flowers in each row = 48
Estimated no of flowers in the garden
= No of rows * No of flowers in each row
= 345*48
= 16,560

Applying the 30-60-90 Theorem, Solve this.
Answer:
'y' would be 24
'x' would be 12[tex]\sqrt{3}[/tex]
Step-by-step explanation:
the ratio of sides in a 30-60-90 triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2
so the side across from the 60 degree angle is [tex]\sqrt{3}[/tex] times the side of the 30°
the side across from the 90 degree angle is double the side of the 30°
so in this problem 'y' would be 24 and 'x' would be 12[tex]\sqrt{3}[/tex]
Answer:
Step-by-step explanation:
take 30 degree as reference angle

use a formula to find the area of the figure
Answer: C. 13.5
Step-by-step explanation:
9x3= 27
27 divided by 2= 13.5
The formula for the area of a triangle is: A = 1/2 * b * h
In this problem, we are given the base (9 ft) and the height (3 ft). Therefore, we can use the formula.
A = 1/2 * 9 * 3
A = 1/2 * 27
A = 13.5 ft^2

Rowena and Arlene are going to make a triangular path in her garden. The sides will be 20 feet, 36 feet, and 18 feet. What is the total length of the path? Answer the questions that follow using AGONSA.
Answer: 74feet
Step-by-step explanation:
In this case, to calculate the total length of the path, we have to find the perimeter of the shape which is a triangle.
It should be noted that the perimeter of a triangle is the addition of all of its sides. The sides given here are 20 feet, 36 feet, and 18 feet. Therefore, the total length will be:
= 20ft + 36ft + 18ft
= 74ft
The perimeter of a triangle is the sum of all sides of the triangle. Then the path length is 74 feet.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Rowena and Arlene are going to make a triangular path in her garden.
The sides will be 20 feet, 36 feet, and 18 feet.
The length of the path is given by the perimeter of the triangle. Then we have
Length of path = 20 + 36 + 18
Length of path = 74 ft.

Answer:
a. 12
b. 15
c. (2, -2.5)
Step-by-step explanation:
a. The points lie on a horizontal line, so the distance between them is the difference of their x-coordinates: 4 -(-8) = 12 units.
__
b. The length BD is the diagonal of the rectangle. Its length is given by the distance formula as ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((-8 -4)^2 +(-7 -2)^2) = √((-12)^2 +(-9)^2) = √(144 +81) = √225
d = 15
The distance between B and D is 15 units.
__
c. The midpoints of AC and BD are the same:
(A +C)/2 = ((-8, 2) +(4, -7))/2 = (4, -5)/2 = (2, -2.5)
(B +D)/2 = ((4, 2) +(-8, -7))/2 = (4, -5)/2 = (2, -2.5)
Point (2, -2.5) can be used to locate the lake.

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-6,3). What is the vertex of the function defined as
g(x) = f(x - 2) – 5?
Answer:
The vertex of g(x) is (-4, -2)
Step-by-step explanation:
Let's define general translations:
Vertical translation:
For a function f(x), a vertical translation of N units (So the whole graph of f(x) is translated N units in a given direction) is defined as:
g(x) = f(x) + N
such that:
If N is positive, the translation is upwards
if N is negative, the translation is downwards.
Horizontal translation:
Similar than before, for a function f(x) a horizontal translation of N units is written as:
g(x) = f(x + N)
Where, if N is positive, the translation is to the left
If N is negative, the translation is to the right.
Here, we have the transformation:
g(x) = f(x - 2) - 5
This is a transformation that moves the whole graph of f(x):
2 units to the right
5 units downwards.
So, if a point like (x, y) was in the graph of f(x)
After the translation, that point will be (x + 2, y - 5)
Then, if the original vertex was (-6, 3), the new vertex will be:
(-6 + 2, 3 - 5)
(-4, -2)
The vertex of g(x) is (-4, -2)
