To represent the linear function in order for the data the value of a=18.
What is a linear function?
In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
It is given that for a linear function the value is changing at the rate of 5 so we can see in the table as the function independent value is changing then the value of the dependent linear function increases by 5.
So the value of a will be equal to 18.To represent the linear function in order for the data the value of a=18.

A school district is considering a change that would involve switching the daily start times for its elementary and
high schools. Administration wants to take a sample of parents from each type of school and perform a two-
sample test to see if the proportion who support the change is significantly different between the two groups.
Which of the following are conditions for this type of test?
Using the Central Limit Theorem, it is found that each random sample must have at least 10 parents supporting the change and 10 opposing.
What does the Central Limit Theorem state?It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

The function f is given by f(x) = 2*, while the function g is given by g(x) = 4.2%.
Kiran says that the graph of g is a vertical scaling of the graph off. Mai says that the
graph of g is a horizontal shift of the graph off. Do you agree with either of them?
Explain your reasoning.
DO
I agree with Kiran that the graph of g(x) = [tex]4* 2^{x}[/tex] is a vertical scaling of the graph of f(x) = [tex]2^{x}[/tex],
Define the term scaling of the graph?Scaling of the graph refers to the process of stretching or shrinking a graph of a function either vertically or horizontally, while maintaining the shape of the graph.
If the function f is given by f(x) = [tex]2^{x}[/tex],
the function of g is given by g(x) = [tex]4* 2^{x}[/tex]
I agree with Kiran that the graph of g(x) = [tex]4* 2^{x}[/tex] is a vertical scaling of the graph of f(x) = [tex]2^{x}[/tex],
To see this, note that both functions have a base of 2 raised to the power of x. However, the function g has an additional factor of 4 multiplying [tex]2^{x}[/tex]. This means that g is 4 times larger than f for any given value of x.
On the other hand, I disagree with Mai that the graph of g is a horizontal shift of the graph of f. A horizontal shift occurs when a function is moved left or right along the x-axis. However, both f and g have the same base, so the shape of their graphs is the same. The only difference is the vertical scaling due to the additional factor of 4 in g.

A quadrilateral has two angles that measure 222° and 81°. The other two angles are in a ratio of 6:13. What are the measures of those two angles?
Answer:
Other two angles of quadrilateral measures 18° and 39°Step-by-step explanation:
Given that a quadrilateral has two angles that measure 222° and 81°.
Let other two angles of quadrilateral be 6x and 13x. We know that sum of all the angles of quadrilateral is 360°.
➝ 222 + 81 + 6x + 13x = 360°
➝ 303 + 19x = 360°
➝ 19x = 360° - 303
➝ 19x = 57
➝ x = 57/19
➝ x = 3
Hence,
6x = 6(3) = 18° 13x = 13(3) = 39°∴ Other two angles of quadrilateral measures 18° and 39°
Answer:
Measurement of other two angles are 39° and 19°
Step-by-step explanation:
Given :-
Quadrilateral has two angles of measurement 222° and 81° and the other two angles are in ratio of 6:13To find:-
The measurement of other two anglesSolution:-
Let the value of other two angles be 6x and 13x
We know , the sum of angle inside a quadrilateral is 360°
222° + 81° + 13x + 6x = 360°
19x = 360° - 303°
x = 3
So , the value of other two angles are

Find the area of the shaded region.
Answer:
Step-by-step explanation:
Remark
The method of finding the area of the ring is to find the area of the outer ring and subtract the area of the hole in the middle.
Outer ring
r = 10 + 4 = 14 inches
Area = pi * r^2
Outer ring area = pi * 14^2
Outer ring area = 196 pi
Inner hole
Area unshaded part = pi * r^2
r = 10
Area = pi * 10^2
Area = 100 pi
Area of the shaded part
area of the shaded part = outter circle area - inner circle area
outter circle area = 196 * pi
inner circle area = 100 pi
Area of the shaded part = 196 pi - 100 pi
Area of the shaded part = 96 pi
pi = 3.14
Area of the shaded part = 96 * 3.14
Answer area of the shaded part = 301.44
Answer area of the shaded part = 301.4 rounded to the nearest tenth

Inner Circle area hole = 324 pi
Area of the shaded part = outter circle - inner circle
Area of the shaded part = 676 pi - 324 pi
Area of the shaded part = 352 pi

A car tyre has a diameter of 60 cm.
How far will the wheel travel in one revolution?
Answer:
Step-by-step explanation:
If 60cm is the outer diameter of the rim, then the rim without a tire would travel 188.50 (not 188.4) cm per revolution. There will of course be a tire, and the extra diameter of wheel+tire will increase the distance traveled by the bike. If e.g. the tire is 3cm from bead to outermost tread (and is properly inflated), then the extra circumference would be 2 x 3cm x pi = 18.850cm of distance traveled, for a total of just over 207.3 cm per revolution.

Having some trouble with this question, any help? A wire supporting a radio tower is secured to the ground 14 m from the base of the tower. If the angle between the ground and the wire is 57°, what is the height of the tower, to the nearest tenth of a metre?
By using what we know about right triangles, we will see that the height is 11.7 m.
How to find the height of the tower?We can view this as a right triangle, such that the wire is the hypotenuse of said triangle.
We know that the hypotenuse measures 14 m, and the angle between the ground and the wire si 57°. The height would be the opposite cathetus to that angle, so we can use the rule:
Sin(a) = (opposite cathetus)/hypotenuse
Replacing the values we get:
Sin(57°) = H/14m
Sin(57°)*14m = H = 11.7m
The height of the tower is 11.7 meters.

Answer:

Step-by-step explanation:
In this problem, we don't know the length or width. All we do know is that the length is 5 feet longer than the width, and that the perimeter is 54 feet. Both lengths plus both widths equals the perimeter. To solve this problem, you must give the width, the value of x.
Step 1: Draw a rectangle where the width is x and the length is x + 5.
Step 2: Find the sum of the lengths and the sum of the widths
2 times the length plus 2 times the width equals the perimeter
2(x + 5) + 2(x) = 54
Step 3: Solve for the width
2(x + 5) + 2(x) = 54
2x + 10 + 2x = 54 (Distributive Property)
4x + 10 = 54 (Group Like Terms)
4x = 44 (Subtraction Property of Equality)
4x/4 = 44/4
x = 11 (Division Property of Equality)
x = width = 11
Step 4: Solve for the length
x + 5 = length
11 + 5 = 16
Length = 16. So (3) must be the answer.
Find an equation for the inverse for each of the following relations. y= (2/3)x-5
Answer:
y = 3/2x + 15/2
or
y = [tex]\frac{3x+15}{2}[/tex]
Step-by-step explanation:
To solve inverse functions, switch the x and y in the equation, then
solve for y.
original equation :
y = (2/3)x - 5
switch x and y
x = (2/3)y - 5
add 5 to both sides
x + 5 = (2/3)y
Multiply both sides by the reciprical of (2/3)
(3/2)(x+5) = (3/2)(2/3)y
distribute and simplifiy
(3/2x +15/2) = y
or
y = (3/2x) +(15/2)
Which equation has only one solution? |x – 5| = –1 |–6 – 2x| = 8 |5x 10| = 10 |–6x 3| = 0
The linear equation which has only one solution would be |–6x + 3| = 0
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0.
|x – 5| = –1
The absolute function cannot be equal to the negative. so we cannot solve this absolute function.
|–6 – 2x| = 8
For this absolute function, we make two equations here
-6-2x= 8 and -6-2x= 8. So we will get two solutions for x.
|5x + 10| = 10
For this absolute function, we make two equations here
5x+10= 10 and 5x+10= -10. So we will get two solutions for x
|–6x + 3| = 0
For this absolute function we make two equations
-6x+3=0 and -6x+3=-0.
Both have the same 0 on the right side. So we will get only one solution for x
