Answer:
The vertex is located on the x-axis between the second and third quadrants
Step-by-step explanation:
Whereby the function is f(x) = (x + 3)², we have;
f(x) = (x + 3)² = x² + 6·x + 9
The vertex, (h, k), of the quadratic function given in general form, a·x² + b·x + c is found as follows;
h = -b/(2·a) and k = f(h)
Therefore by comparison of the given quadratic function and the general form of a quadratic function, we have;
a = 1, b = 6, c = 9
h = -6/(2 × 1) = -3
k = f(-3) = (-3)² + 6 × (-3) + 9 = 0
The vertex (h, k) = (-3, 0)
Therefore, the location of the vertex is on the x-axis axis between the second and the third quadrant.
Mario was shopping for a new camera. He found one with an original price of $125.00 and is marked 45% off. Sale tax for the item is 5.2%. What is the final price of the camera, including tax?
Answer:
72.33
Step-by-step explanation:
45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

The function g(x) represents the amount of money in a savings account x years after it is opened.
What does the statement, g(10) - g(9) = $5,000, represent?
A.
The initial balance of the account was $5,000.
B.
Between nine and ten years after opening the account, the balance shrank by $5,000.
C.
Between nine and ten years after opening the account, the balance grew by $5,000.
D.
Ten years after opening the account, the balance was $5,000.
Answer:
C
Step-by-step explanation:
Between nine and ten years after opening the account, the balance grew by $5,000.
Between nine and ten years after opening the account, the balance grew by $5,000. The correct answer would be an option (C)
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function g(x) represents the amount of money in a savings account x years after it is opened.
The statement g(10) - g(9) = $5,000 represents the difference in the balance between 9 and 10 years after opening the account, and since the difference is positive, it means that the balance grew by $5,000.
Hence, the correct answer would be an option (C)

If the triangle is reflected over the y axis what coordinate pair would be contained within the triangle
Answer:
(-4,-4)
Step-by-step explanation:
The reflected triangle will be in the third quadrant. Option 2 is in the first quadrant, option 3 is in the first quadrant as well, and option 4 is in the second quadrant. That leaves option 1, which you can see is in the third quadrant. Option 1, (-4,-4), is the only plausible solution.

If you take the square root of 9, it's 3
if you take the square root if 16, it's 4
I would guess it to be about 3.2
Answer:
Step-by-step explanation:
Lily , we know that [tex]3^{2}[/tex] =9 and [tex]4^{2}[/tex] = 16 so we know that [tex]x^{2}[/tex] = 10 , where 10 is an answer to x squared, then X lies between 3 and 4 , see?
Shirlee cleans house as a side job, this weekend she made $425. If she puts 15% towards her savings how much will she put in her savings account?
Answer:
$63.75
Step-by-step explanation:
Find how much she will put in her savings account by finding 15% of 425
Multiply 425 by 0.15:
425(0.15)
= 63.75
So, Shirlee will put $63.75
Answer:
$63.75
Step-by-step explanation:
Since percent is out of 100. 15% divided by 100%, multiplied by 425.

76 cm a 52 cm Find the area of the regular pentagon (the answer has one digit after the decimal point)
Answer:
98.8 cm²
Step-by-step explanation:
Hi there!
[tex]A=\frac{1}{2} Pa[/tex] where P is the perimeter of the pentagon and a is the apothem (the line going from the center of the pentagon one edge)
1) Find the perimeter
[tex]P=5l[/tex] where l is the side length
Plug in the side length 7.6 cm
[tex]P=5(7.6)\\P=38[/tex]
Therefore, the perimeter of the pentagon is 38 cm.
2) Find the area
[tex]A=\frac{1}{2} Pa[/tex]
Plug in the perimeter (38) and the apothem (5.2)
[tex]A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (38)(5.2)\\A=\frac{1}{2} (197.6)\\A=98.8[/tex]
Therefore, the area of the pentagon is 98.8 cm².

Solve the following quadratic by
completing the square.
y = x2 – 8x + 5
Answer:
x = 4 ± √11
Step-by-step explanation:
hello :
x²-8x+5= x² -2(4 )(x)+5
x²-8x+5= x² -2(4 )(x)+5 = ( x² -2(4 )(x) +4²) -4²+5
= (x-4)²-11 .....( completing the square )
x²-8x+5= 0 means : (x-4)²-11 = 0
(x-4)²=11 but : 11 = (√11)² = ( - √11)²
x-4 =√11 or x-4 = -√11
x = 4 ± √11
Answer:
x = 4 ± [tex]\sqrt{11}[/tex]
Step-by-step explanation:
To solve the equation let y = 0 , that is
x² - 8x + 5 = 0 ( subtract 5 from both sides )
x² - 8x = - 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 5 + 16
(x - 4)² = 11 ( take the square root of both sides )
x - 4 = ± [tex]\sqrt{11}[/tex] ( add 4 to both sides )
x = 4 ± [tex]\sqrt{11}[/tex]

The school that Shawna goes to is selling tickets to a spring musical. On the first day of ticke sales the school sold 7 adult tickets and 7 student tickets for a total of $91. The school took ir $170 on the second day by selling 14 adult tickets and 12 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answer:
price of an adult ticket = a = $7
price of a student ticket = s = $6
Step-by-step explanation:
price of an adult ticket = a
price of a student ticket = s
7a + 7s = 91 (1)
14a + 12s = 170 (2)
Multiply (1) by 2
7a + 7s = 91 (1) × 2
14a + 14s = 182 (3)
14a + 12s = 170 (2)
Subtract (2) from (3) to eliminate x
14s - 12s = 182 - 170
2s = 12
s = 12/2
s = 6
Substitute s = 6 into (1)
7a + 7s = 91 (1)
7a + 7(6) = 91
7a + 42 = 91
7a = 91 - 42
7a = 49
a = 49/7
a = 7
price of an adult ticket = a = $7
price of a student ticket = s = $6

The Golden Gate bridge was built in San Francisco, California, in 1937. Until 1964, it was the longest suspension span in the world. The length of the cable from the top of the tower to where it anchored in the concrete is 2332 m, and the height of each tower is 152 m. Assuming the cable forms a straight line, how far from the base of the tower is the cable anchored?
the value of y varies directly x, and when x = 5y=25. What is the value of y when x is 20?
Pls ASAP T.T
Answer: i don't think its possible for 20 to equal 5y and 25 the reason why is because for 5y to equal 20 y=4 that may be the answer but im not completely sure if it was supposed to be 20=x and 5y+25=x
Step-by-step explanation:
if it was supposed to be 20=x and 5y+25=x the new equation would be 5y+25= 20 you then divide 5 from both sides. and get y=4
but if the equation was supposed to be x+5y=25 and x equals 20 then y would equal 1

Members of a student council are designing a school float for a parade. They decide to poll 10% of the student body to get feedback about the
theme they have chosen.
What would most likely happen if they decided to randomly sample 5% of the student body instead?
Answer: The sample portion would less closely model the population proportion
Answer:
Answer is that is will less closely model to the total population.
Step-by-step explanation:
This is because there are less numbers to be chosen and will be harder to find a proper medium and mean.
