Answer:
Step-by-step explanation:
16 feet
Answer:
Option C.
Step-by-step explanation:
Let x be the distance from holes center in feet and y be the depth from level ground in feet.
The given table represents a quadratic functions.
x : -2 0 2
y : -6 -8 -6
The depth from level ground in feet is same at x=-2 and x=2 it means the hole is symmetric about the line x=0.
The value of a quadratic function is on its extreme at line of symmetry.
In the given function the line of symmetry is x=0. So, the depth of the hole is defined on x=0.
From the table it is clear that at x=0 the depth from level ground is 8 feet.
Therefore, the correct option is C.
If f(x) = 1/x+1 and g(x) = x^2, what does f(g(-1)) equal?
A. -1
B. -1/2
C. 0
D. 1/2
E. 1
Answer:
D: f(g(-1)) = 1/2
Step-by-step explanation:
f(x) = 1/(x + 1)
g(x) = x²
g(-1) = 1
f(g(-1)) = 1/(1 + 1)
f(g(-1)) = 1/2

How many times does the quadratic function below intersect the x-axis?
y = 2x2 +7x+6
Answer:
once
Step-by-step explanation:
since the equation is liner, with x simply to the first power, it will only cross the x axis once. x^2 would cross the x axis twice, x^3 would cross it three times, and so on
Given quadratic function [tex]y = 2x^{2} +7x+6[/tex] intersects the x-axis two times.
What is quadratic function?" Quadratic function is defined as the function which has variables with highest degree two."
According to the question,
Given quadratic function,
[tex]y = 2x^{2} +7x+6[/tex]
If quadratic function intersect x-axis value of [tex]y=0[/tex] we have,
[tex]2x^{2} +7x+6 =0\\\\\implies 2x^{2} + 4x+3x + 6=0\\ \\\implies 2x(x+2) + 3(x+2)=0\\\\\implies (2x+3) (x+2)=0\\\\\implies 2x+3 =0 \ or \ x+2=0\\\\\implies x = \frac{-3}{2} \ or \ x =-2\\\\\implies x = -1.5 \ or \ x =-2[/tex]
As shown in graph , quadratic function intersect x-axis at two points [tex](-2,0)[/tex] and [tex](-1.5,0)[/tex].
Hence, given quadratic function [tex]y = 2x^{2} +7x+6[/tex] intersects the x-axis two times.

Answer:
(5, 2), (14, -7), (5, -16), (-4, -7)
Step-by-step explanation:
There is an infinite number of possibilities. However, I suspect "they" are thinking of integral coordinates and equally spaced points.
In that case, you could move up nine units to (5, 2).
This puts eight points between A and B. I have numbered them in the diagram below.
Any point on a circle with radius 9 and centred at (5, -7) is 9 units from A, but only these four points have integral coordinates for themselves and for the points in between:
Up from A: (5, 2)
To the right: (14, -7)

3. Your father gives one-half of the money in his pocket to your mother, one-fourth of what is left to your brother, and one-third of what then remains to your sister. He then splits the rest with you. If you get $4.00, how much did your father start with?
Answer:
The father start with $16
Step-by-step explanation:
Let
x -----> the original amount of money
step 1
Your father gives one-half of the money in his pocket to your mother
[tex]\frac{1}{2}(x)=\frac{1}{2}x[/tex]
The remaining is
[tex]x-\frac{1}{2}x=\frac{1}{2}x[/tex]
step 2
Your father gives, one-fourth of what is left to your brother
[tex](\frac{1}{4})\frac{1}{2}x=\frac{1}{8}x[/tex]
The remaining is
[tex]\frac{1}{2}x-\frac{1}{8}x=\frac{3}{8}x[/tex]
step 3
Your father gives one-third of what then remains to your sister
[tex](\frac{1}{3})\frac{3}{8}x=\frac{3}{24}x[/tex]
The remaining is
[tex]\frac{3}{8}x-\frac{3}{24}x=\frac{6}{24}x=\frac{1}{4}x[/tex]

Solve y = x + 4 for x.
x = y − 4
x = y + 4
x = −y + 4
x = −y − 4
Answer:
x=y-4
Step-by-step explanation:
y=x+4
-4
y-4=x
Answer:
Option A.
Step-by-step explanation:
y = x + 4
As we know if we perform a similar operation on both the sides of the equation it doesn't affect the parent equation.
So we subtract 4 on both sides of the equation
y - 4 = (x + 4) - 4
x = y - 4
Therefore, option A. will be the answer.

In a community garden (shown to the right) you want to plant and fence in a vegetable garden that is adjacent to your friend’s garden. You have at most 54 ft of fence, and the fence must surround all four sides of your garden. What are the possible lengths of your garden
To find the possible lengths of the garden, use the perimeter formula and solve the inequality x <= 27 ft.
Explanation:To find the possible lengths of your garden, you need to determine the perimeter of the garden. Since you have at most 54 ft of fence, the perimeter must be less than or equal to 54 ft.
Let's assume the length of your garden is 'x', then the width would be (54 - 2x)/2.
The perimeter formula is P = 2L + 2W, so substituting the values we have, 2x + 2[(54 - 2x)/2] <= 54.
Simplifying this inequality, we get x + 54 - 2x <= 54. Solving for 'x', we get x <= 27.
Therefore, the possible lengths of your garden are any value less than or equal to 27 ft.

Nine less than a number is between 3 and 8. Find the range of numbers that make this true.
Answer:
The range of the numbers make this true is (12 , 17)
Step-by-step explanation:
Lets explain how to solve the problem
The statement is:
→ Nine less than a number is between 3 and 8
Assume that the number is x
∵ The number is x
∴ Nine less than a umber is x - 9
→ The difference is between 3 and 8
∴ 3 < x - 9 < 8
∴ Nine less than a number is between 3 and 8 ≡≡≡ 3 < x - 9 < 8
Lets solve the inequality to find the range of x
∵ 3 < x - 9 < 8
Add 9 to each side
∴ 3 + 9 < x - 9 + 9 < 8 + 9
∴ 12 < x < 17
∵ There is no mention about the type of the number that is integer or
rational number or real number
∴ The range of x is any number between 12 and 17
The range of the numbers make this true is (12 , 17)
Remember you can use any number between 12 and 17 but you
cannot use 12 or 17
The range of numbers that make this true is (12, 17).
Let the numbers be represented by x.
Therefore, based on the information given, the number will be:
x - 9 = 3
x = 3 + 9
x = 12
The first number is 12.
x - 9 = 8.
x = 8 + 9
x = 17
Therefore, the range of numbers that make this true is (12, 17).

A rectangle has a length of 27 feet less than nine times its width. If the area of the rectangle is 972 find the length of the rectangle
The length of Rectangle is 81 feet's.
We have a rectangle which has a length of 27 feet less than nine times its width and the area of the rectangle is 972.
We have the length of the rectangle.
State the formula to calculate the Perimeter and Area of Rectangle?The Area of a Rectangle = A = L x B
The Perimeter of a Rectangle = P = 2(L + B)
According to the question, we have -
Area = 972 square feet's.
Let the length of rectangle be x and width be y.
Then -
x = 9y - 27
Now -
Area = 972
xy = 972
y(9y - 27) = 972
9y(y - 3) = 972
y(y - 3) = 108
[tex]$y^{2} -3y -108 = 0[/tex]
(y - 12)(y + 9) = 0
y - 12 = 0 or y + 9 = 0
y = 12 or y = - 9
But width cannot be negative. Therefore -
y = 12.
Now, length = x = 9y - 27 = 12 x 9 - 27 = 108 - 27 = 81.
Hence, the length is 81 feet's.
