This graph represents a quadratic function. What is the function’s equation written in factored form and in vertex form?
Answer:
f(x) = 2x(x - 8)
f(x) = 2(x - 2)² - 8
Step-by-step explanation:
Let the equation of the quadratic function is,
f(x) = a(x - h)² + k
Here, (h, k) is the vertex of the function.
From the graph attached,
Vertex of the parabola → (2, -8)
Therefore, equation of the function will be,
f(x) = a(x - 2)² - 8
Since, the graph passes through origin (0, 0),
f(0) = a(0 - 2)² - 8
0 = 4a - 8
a = 2
Equation of the given parabola will be,
f(x) = 2(x - 2)² - 8
= 2(x² - 4x + 4) - 8
= 2x² - 8x + 8 - 8
= 2x² - 8x
= 2x(x - 8)
Therefore, factored form of the function will be,
f(x) = 2x(x - 8)

made three-point shots in her first game and in her second game. She also made two-point shots in each game. How many total points did score in the 2 games?
Answer:
the total no of points score in the 2 games is 10 points
Step-by-step explanation:
Given that
She made 3 points in her first game and her second game
Also, she made 2 point shots in each game
we need to find out the no of total points did she score in the 2 games
So,
The number of total points is
= 3 + 3 + 2 + 2
= 10 points
Hence, the total no of points score in the 2 games is 10 points

What is the area of the shaded region?
Answer:
42.5 square.cm
Step-by-step explanation:
Find the diagram attached
Area of the shaded portion = area of square - area of circle
Area of square = L²
Area of square = 11 × 11
Area of square = 121 square centimetres
Area of circle = pir²
r is the radius of the circle = 5cm
Area of the circle = 3.14×5²
Area of the circle = 3.14×25
Area of the circle = 78.5 square. cm
Area of the shaded region = 121 - 78.5
Area of the shaded region = 42.5 square.cm
Answer:
397.39cm

Answer:
The answer is 9/10
Step-by-step explanation:
8/10 is the same thing as ⅘, ⅘ is just simplified
⅖ is less than ⅘ so it would come before c
6/5 is more than 1 so it wouldn’t be on that number line.
Answer:
OK.
My answer is based on 2 things.
1. That the furthest point on the left is 0( That other little distance is ignored)
2. That the point C is equidistant from 4/5 and 1.
If so..
Then
4/5 + x + x =1
4/5 +2x = 1
2x= 1-4/5
x=1/10
Now
From 4/5 to C is x...
Then Position C would be
4/5 + 1/10
c= 9/10
Or by simply making guesses...
All Other options are greater than 1... So It can't be those cos C is less than 1

A combined total of $53,000 is invested in two bonds that pay 2% and 8.5% simple interest. The annual interest is $3,335.00. How much is invested in each bond? The amount invested at 2% is $ The amount invested at 8.5% is $
Answer:
8.5 = $35,000
2% = $18,000
Step-by-step explanation:
two equations can be derived from the question
x + y = $53,000 equation 1
0.02x + 0.085y = $3,335.00. equation 2
x = amount invested in 2% bond
y = amount invested in 8.5% bond
multiply equation 1 by 0.02
0.02x + 0.02y = 1060 equation 3
subtract equation 2 from 3
0.065y = 2275
y = 35,000
substitute for y in equation 1
53,000 - 35,000 = 18,000
2. In 1990, there were 1,200 cell phone subscribers in a small-town of Stephenville. The number of subscribers increased by 75% per year after 1990. How many cell phone subscribers were in Stephenville in 1999?
Answer: [tex]184,724.153[/tex]
Step-by-step explanation:
Given
In 1990, there were 1200 cell phone subscriber in small town of stephenville
It is increasing by 75% per year after 1990
In year 1991 it is
[tex]\Rightarrow 1200+1200\times 0.75\\\Rightarrow 122(1.75)[/tex]
In year 1992 it is
[tex]\Rightarrow 1200(1.75)+1200(1.75)\times 0.75\\\Rightarrow 1200(1.75)(1+0.75)\\\Rightarrow 1200(1.75)^2[/tex]
So, it is increasing as [tex]1200(1.75)^x[/tex]
where [tex]x=[/tex]no of years spent
After 9 years, it is
[tex]\Rightarrow 1200(1.75)^9=184,724.153[/tex]
Which set of coordinates follows these two rules x coordinate start with 4 and add 4 to each term y coordinate start with 4 and multiply each term by 2
A (4, 4), (8, 8), (12, 16)
B (4, 4), (8, 8), (16, 16)
C (4, 4), (6, 16),(8, 64)
D (4, 4), (16,2), (64,0)
Answer:
A; (4,4), (8,8) and (12,16)
Step-by-step explanation:
The value x starts with 4 and add 4 to each term
The value y start with 4 and each term next is multiplied by 2
So for x, we have;
4 , (4 + 4) and (4 + 4 + 4)
= 4,8 and 12
For y;
we have ;
4, (4 * 2) , (4 * 2 * 2)
= 4, 8, 16
so pairing up, we have;
(4,4), (8,8) and (12,16)
