Answer:
The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}
Step-by-step explanation:
The domain is the set of values of the input (x)
The range is the set of values of the output (y)
In the given figure
∵ x is the input
∴ The set of the values of x is the domain
∵ Y is the output
∴ The set of the values of y is the range
∵ The smallest value of y is -6
∵ The greatest value of y is 8
→ That means values of y of the graph are from -6 to 8
∴ -6 ≤ y ≤ 8
∴ The range = {y : y ∈ R, -6 ≤ y ≤ 8}
∴ The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

The length of time, y hours, it takes to put a jigsaw puzzle together is inversely proportional to the number of children, x, working on it. It takes 16 children 6 hours to put the jigsaw puzzle together. How many children are needed to put the same jigsaw puzzle together in 4 hours?
Answers
Answer:
24 children
Step-by-step explanation:
If the length of time, y hours, it takes to put a jigsaw puzzle together is inversely proportional to the number of children, x, this is represented as;
[tex]y \alpha \frac{1}{x}\\y =\frac{k}{x}[/tex]
k is the constant of proportionality
If it takes 16 children 6 hours to put the jigsaw puzzle together, this means at x = 16, y = 6
Substitute:
6 = k/16
k = 6*16
k = 96
W are to find number of children needed to put the same jigsaw puzzle together in 4 hours, this is done by substituting k = 96 and y = 4 into the expression y = k/x
y = 96/4
y = 24
Hence it will take 24 children to put the same jigsaw puzzle together in 4 hours

A line with a slope of 3 passes
through the points (2, -1) and (4, 5).
Which of the following is not an
equation of the line that passes
through those points?
B. y = 3x-11
A. y+1 = 3(x-2)
D. y-5 = 3(x-4)
C. y = 3x-7
Answers
Answer:
We conclude that only the equation y = 3x-11 is not an equation of the line that passes through the points.
Hence, option B is correct.
Step-by-step explanation:
Given the points
(2, -1)(4, 5)Finding the slope between (2, -1) and (4, 5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(4,\:5\right)[/tex]
[tex]m=\frac{5-\left(-1\right)}{4-2}[/tex]
[tex]m=3[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 3 and the point (2, -1)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-2=3\left(x-\left(-1\right)\right)[/tex]
[tex]y-2=3\left(x+1\right)[/tex]
Add 2 to both sides
[tex]y-2+2=3\left(x+1\right)+2[/tex]
[tex]y=3x+5[/tex]
So, y = 3x+5 is one of the equation lines.
We can also check by substituting the values m = 3 and the point (4, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
y - 5 = 3(x-4)
So, y - 5 = 3(x-4) is also one of the equation lines.
Now, let say take the point (4, 5) an substitute in y = 3x-11
y = 3x-11
put x = 4 and y = 5
5 = 3(4)-11
5 = 12-11
5 = 1
FALSE!
Hence, the equation y = 3x-11 does not pass through (4, 5). Thus, the equation y = 3x-11 is not an equation of the line that passes through the points.
Now, let say take the point (4, 5) an substitute in y+1 = 3(x-2)
y+1 = 3(x-2)
put x = 4 and y = 5
5+1 = 3(4-2)
6 = 3(2)
6 = 6
TRUE!
Now, let say take the point (2, -1) an substitute in y+1 = 3(x-2)
-1+1 = 3(2-2)
0 = 0
TRUE!
Thus, the equation y+1 = 3(x-2) is an equation of the line that passes through the points.
Now, let say take the point (2, -1) an substitute in y = 3x-7
y = 3x-7
put x = 2 and y = -1
-1 = 3(2) - 7
-1 = 6-7
-1 = -1
TRUE!
Now, let say take the point (4, 5) an substitute in y = 3x-7
y = 3x-7
put x = 4 and y = 5
5 = 3(4)-7
5 = 12-7
5 = 5
TRUE!
Thus, the equation y = 3x-7 is an equation of the line that passes through the points.
Conclusion:
We conclude that only the equation y = 3x-11 is not an equation of the line that passes through the points.
Hence, option B is correct.

In a rectangle FGHI, diagonals FH and GI intersect at E
What is the length of FH?
Answers
Answer:
The length of [tex]\overline {FH}[/tex] is;
D. 38 units
Step-by-step explanation:
The given parameters are;
The type of the given quadrilateral FGHI = Rectangle
The diagonals of the quadrilateral = [tex]\overline {FH}[/tex] and [tex]\overline {GI}[/tex]
The length of IE = 3·x + 4
The length of EG = 5·x - 6
We have from segment addition postulate, [tex]\overline {GI}[/tex] = IE + EG
The properties of a rectangle includes;
1) Each diagonal bisects the other diagonal into two
Therefore, [tex]\overline {FH}[/tex] bisects [tex]\overline {GI}[/tex], into two equal parts, from which we have;
IE = EG
[tex]\overline {GI}[/tex] = IE + EG
3·x + 4 = 5·x - 6
4 + 6 = 5·x - 3·x = 2·x
10 = 2·x
∴ x = 10/2 = 5
From which we have;
IE = 3·x + 4 = 3 × 5 + 4 = 19 units
EG = 5·x - 6 = 5 × 5 - 6 = 19 units
[tex]\overline {GI}[/tex] = IE + EG = 19 + 19 = 38 units
[tex]\overline {GI}[/tex] = 38 units
2) The lengths of the two diagonals are equal. Therefore, the length of segment [tex]\overline {FH}[/tex] is equal to the length of segment [tex]\overline {GI}[/tex]
Mathematically, we have;
[tex]\overline {FH}[/tex] = [tex]\overline {GI}[/tex] = 38 units
∴ [tex]\overline {FH}[/tex] = 38 units.

m∠A = m∠O
m∠A = 65°
AM and SO are congruent sides
AM = SO
AM = 86
m∠S and m∠M are alternate interior angles so they're congruent.
m∠S = m∠M
m∠S = 60°
ON and NA are congruent sides.
ON = NA
ON = 75
m∡SNO, m∠S, and m∠O form a triangle so they should add up to 180°
m∡SNO + m∠S + m∠O = 180°
m∡SNO + 60 + 65 = 180
m∡SNO + 125 = 180
Subtract both sides by 125
m∡SNO = 55°

You are swinging a bucket in a circle at a velocity of 7.8 ft/s. The radius of the circle you are making is 1.25 ft. The acceleration is equal to one over the radius multiplied by the velocity squared.
a. What is the acceleration of the bucket?
b. What is the velocity if the acceleration is 25 ft/sec2?
Answers
Given that,
velocity, v = 7.8 ft/s
Radius, r = 1.25 ft
To find,
a. What is the acceleration of the bucket?
b. What is the velocity if the acceleration is 25 ft/sec²?
Solution,
(a) The centripetal acceleration is given by :
[tex]a=\dfrac{v^2}{r}[/tex]
Put v = 7.8 ft/s and r = 1.25 ft
[tex]a=\dfrac{(7.8)^2}{1.25}\\\\=48.672\ ft/s^2[/tex]
(b) Put a = 25 ft/s² to find velocity.
[tex]v=\sqrt{ar} \\\\v=\sqrt{25\times 1.25} \\\\v=5.59\ ft/s[/tex]
Hence, this is the required solution.

Answer:
∠A = 66.2°
Step-by-step explanation:
The sum of exterior angles of any polygon is 360°, so you have ...
(3x +10)° +(5x)° +(2x +4)° = 360°
10x +14 = 360 . . . . . . . . . . . . . . .collect terms, divide by °
x + 1.4 = 36 . . . . . . . . . divide by 10
x = 34.6
The interior angle at A is the supplement of the exterior angle there:
∠A = 180° -(3x +10)° = 180° -(3(34.6) +10)°
∠A = 66.2°

Sales tax is [tex]7.6\%[/tex]
The license and title charges are [tex]\$125.13[/tex]
To find: The amount that the credit union will finance.
Solution:
We have,
Cost of car[tex]=\$22,346.16[/tex]
Sales tax is [tex]7.6\%[/tex] of [tex]\$22,346.16[/tex]
Therefore,
sales tax [tex]=\frac{7.6}{100}\times22,346.16=\$1698.31[/tex]
The license and title charges [tex]=\$125.13[/tex]
Now, the amount that the credit union will finance is
