The graph cannot be used to complete the table of values and the missing value of a is 7
How to determine the missing value of y's?The graph represents the given parameter
There are no points plotted on the graph
This means that the table of values cannot be completed
Hence, the graph cannot be used to complete the table of values
How to determine the missing value of a?The table represents the given parameter
On the table, we have the following points
(x, y) = (0, -2), (2, 4), (3, a)
Also, we have that the points fall on a line
This means that the points make a linear equation
By analyzing the x and y values, we can see that
As x increases by 2, y increases by 6
This means that as x increases by 1, y increases by 3
So, when x = 3, the value of y is
y = 4 + 3
Evaluate
y = 7
Rewrite as
a= 7
Hence, the missing value of a is 7

At an amusement park, 640 out of 2,000 tickets sold were discount tickets. What percentage of the tickets were discount tickets?
Answer:
32 percent
Step-by-step explanation:
We can set this up as a fraction: because there are 640 out of 2000, it becomes:
640/2000
We can simplify this to get
320/1000
32/100.

Answer:

Step-by-step explanation:
Just took the asignment.
6 math questions, answer all please for all points
Answer:
See below for answers and explanations
Step-by-step explanation:
Problem 1
Recall that the projection of a vector \(u\) onto \(v\) is \(\displaystyle proj_vu=\biggr(\frac{u\cdot v}{||v||^2}\biggr)v\).
Identify the vectors:
\(u=\langle-10,-7\rangle\)
\(v=\langle-8,4\rangle\)
Compute the dot product:
\(u\cdot v=(-10*-8)+(-7*4)=80+(-28)=52\)
Find the square of the magnitude of vector v:
\(||v||^2=\sqrt{(-8)^2+(4)^2}^2=64+16=80\)
Find the projection of vector u onto v:
\(\displaystyle proj_vu=\biggr(\frac{u\cdot v}{||v||^2}\biggr)v\\\\proj_vu=\biggr(\frac{52}{80}\biggr)\langle-8,4\rangle\\\\proj_vu=\biggr\langle\frac{-416}{80} ,\frac{208}{80}\biggr\rangle\\\\proj_vu=\biggr\langle\frac{-26}{5} ,\frac{13}{5}\biggr\rangle\\\\proj_vu=\langle-5.2,2.6\rangle\)
Thus, B is the correct answer
Problem 2
Treat the football and wind as vectors:
Football: \(u=\langle42\cos172^\circ,42\sin172^\circ\rangle\)
Wind: \(v=\langle13\cos345^\circ,13\sin345^\circ\rangle\)
Add the vectors: \(u+v=\langle42\cos172^\circ+13\cos345^\circ,42\sin172^\circ+13\sin345^\circ\rangle\approx\langle-29.034,2.481\rangle\)
Find the magnitude of the resultant vector:
\(||u+v||=\sqrt{(-29.034)^2+(2.481)^2}\approx29.14\)
Find the direction of the resultant vector:
\(\displaystyle \theta=tan^{-1}\biggr(\frac{2.841}{-29.034}\biggr)\approx -5^\circ\)
Because our resultant vector is in Quadrant II, the true direction angle is 6° clockwise from the negative axis. This means that our true direction angle is \(180^\circ-5^\circ=175^\circ\)
Thus, C is the correct answer
Problem 3
We identify the initial point to be \(R(-2,12)\) and the terminal point to be \(S(-7,6)\). The vector in component form can be found by subtracting the initial point from the terminal point:
\(v=\langle-7-(-2),6-12\rangle=\langle-7+2,-6\rangle=\langle-5,-6\rangle\)
Next, we find the magnitude of the vector:
\(||v||=\sqrt{(-5)^2+(-6)^2}=\sqrt{25+36}=\sqrt{61}\approx7.81\)
And finally, we find the direction of the vector:
\(\displaystyle \theta=tan^{-1}\biggr(\frac{6}{5}\biggr)\approx50.194^\circ\)
Keep in mind that since our vector is in Quadrant III, our direction angle also needs to be in Quadrant III, so the true direction angle is \(180^\circ+50.194^\circ=230.194^\circ\).
Thus, A is the correct answer
Problem 4
Add the vectors:
\(v_1+v_2=\langle-60,3\rangle+\langle4,14\rangle=\langle-60+4,3+14\rangle=\langle-56,17\rangle\)
Determine the magnitude of the vector:
\(||v_1+v_2||=\sqrt{(-56)^2+(17)^2}=\sqrt{3136+289}=\sqrt{3425}\approx58.524\)
Find the direction of the vector:
\(\displaystyle\theta=tan^{-1}\biggr(\frac{17}{-56} \biggr)\approx-17^\circ\)
Because our vector is in Quadrant II, then the direction angle we found is a reference angle, telling us the true direction angle is 17° clockwise from the negative x-axis, so the true direction angle is \(180^\circ-17^\circ=163^\circ\)
Thus, A is the correct answer
Problem 5
A vector in trigonometric form is represented as \(w=||w||(\cos\theta i+\sin\theta i)\) where \(||w||\) is the magnitude of vector \(w\) and \(\theta\) is the direction of vector \(w\).
Magnitude: \(||w||=\sqrt{(-16)^2+(-63)^2}=\sqrt{256+3969}=\sqrt{4225}=65\)
Direction: \(\displaystyle \theta=tan^{-1}\biggr(\frac{-63}{-16}\biggr)\approx75.75^\circ\)
As our vector is in Quadrant III, our true direction angle will be 75.75° counterclockwise from the negative x-axis, so our true direction angle will be \(180^\circ+75.75^\circ=255.75^\circ\).
This means that our vector in trigonometric form is \(w=65(\cos255.75^\circ i+\sin255.75^\circ j)\)
Thus, C is the correct answer
Problem 6
Write the vectors in trigonometric form:
\(u=\langle40\cos30^\circ,40\sin30^\circ\rangle\\v=\langle50\cos140^\circ,50\sin140^\circ\rangle\)
Add the vectors:
\(u+v=\langle40\cos30^\circ+50\cos140^\circ,40\sin30^\circ+50\sin140^\circ\rangle\approx\langle-3.661,52.139\rangle\)
Find the magnitude of the resultant vector:
\(||u+v||=\sqrt{3.661^2+52.139^2}\approx52.268\)
Find the direction of the resultant vector:
\(\displaystyle\theta=tan^{-1}\biggr(\frac{52.139}{-3.661} \biggr)\approx-86^\circ\)
Because our resultant vector is in Quadrant II, then our true direction angle will be 86° clockwise from the negative x-axis. So, our true direction angle is \(180^\circ-86^\circ=94^\circ\).
Thus, B is the correct answer

we conclude that the difference quotient for the function f(x), we get:
[-3*(2x + h) + 4]
How to find the difference quotient for the function f(x)?
For any function f(x), we define the difference quotient as:
( f(x + h) - f(x))/h
In this case, we have:
f(x) = -3x^2 + 4x + 10
Then f(x) is a quadratic function.
Now we replace that in the difference quotient formula so we get:
[ -3(x + h)^2 + 4*(x + h) + 10 - (-3x^2 + 4x + 10)]/h
Now we can simplify that:
[ -3(x + h)^2 + 4*(x + h) + 3x^2 - 4x ]/h
[ -3(x + h)^2 + 4*h + 3x^2 ]/h
[ -3(x^2 + 2xh + h^2) + 4*h + 3x^2 ]/h
[ -3(2xh + h^2) + 4*h]/h = [-3*(2x + h) + 4]
So we conclude that the difference quotient for the function f(x), we get:

Write the slope-intercept form of the equation for each line.
Step-by-step explanation:
points on the line: (4, -2) & (-5, 3)
gradient of the line = -5/9
general equation for all straight lines: y = mx + c
substitute one coordinate and the gradient into the equation. 3 = (-5/9)(-5) + c
therefore, c = 2/9
so the general equation is y = (-5/9)x + 2/9
A rocket is shot from an underground bunker. The height of the rocket after t seconds is given by y= -16t^2 + 176t -384 (measured in feet relative to the surface). Determine how long after the rocket is launched that is will emerge from the ground, and determine how much longer it will be for the rocket to hit the ground.
Solving the quadratic equation, it is found that:
It emerges from the ground after 3 seconds.5 seconds after that, that is, 8 seconds after being launched, it hits the ground.What is a quadratic function?A quadratic function is given according to the following rule:
\(y = ax^2 + bx + c\)
The solutions are:
\(x_1 = \frac{-b + \sqrt{\Delta}}{2a}\)
\(x_2 = \frac{-b - \sqrt{\Delta}}{2a}\)
In which:
\(\Delta = b^2 - 4ac\)
If a < 0, the graph, which is a parabola, is concave down, that is, it is positive only between the two roots.
In this problem, the equation is:
\(y = -16t^2 + 176t - 384\)
Then, the solution is:
\(-16t^2 + 176t - 384 = 0\)
The coefficients are \(a = -16, b = 176, c = -384\), then:
\(\Delta = (176)^2 - 4(-16)(-384) = 6400\)
\(x_1 = \frac{-176 + \sqrt{6400}}{-32} = 3\)
\(x_2 = \frac{-176 - \sqrt{6400}}{-32} = 8\)
Considering that the parabola is concave down, we have that:
It emerges from the ground after 3 seconds.5 seconds after that, that is, 8 seconds after being launched, it hits the ground.You can learn more about quadratic equations at https://brainly.com/question/24764843

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y > −2x + 10 y > 1 over 2x − 2
The shaded area represents the solution of the inequalities. Hence, points A, C, D and K are the solution of the system.
How to graph system of inequalities?Get y first when graphing a linear inequality with two variables, such as x and y alone on one side. Then, take into account the associated equation that was created by switching the inequality sign for an equality sign. This equation has a line as its graph.
The last step is to choose a point that is not on either line (usually (0, 0) is the simplest) and determine whether or not these coordinates satisfy the inequality. If so, shade the portion of the half-plane that contains that point. If not, shade the opposite half-plane.
Create a comparable graph for each of the system's inequalities. The place where all of the system's solutions overlap is known as the system's solution.
Given that, the inequality is:
y ≤ −2x + 10 & y > 1/(2x − 2)
The given points: A(-5,4), B(4,7), C(-2,7), D(-7,1), E(4,-2), F(1,-6), G(-3,-10), H(-4,-4), I(9,3), J(7,-4) and K(2,3).

Select all the correct answers. If the measure of angle is is , which statements are true? The measure of the reference angle is . The measure of the reference angle is . The measure of the reference angle is . cos(0)=-3/10
The measure of angle is θ cannot determine the statements that are true about its reference angle.
There are two issues with the given statement.
First, it does not specify the measure of angle θ.
Second, the statement cos(0)=-3/10 is not related to the reference angle of θ.
The reference angle of θ is the acute angle between the terminal side of θ and the x-axis.
It is always positive and its measure is between 0 and 90 degrees or between 0 and π/2 radians.
The measure of the reference angle of θ is denoted by θ'.
To determine the reference angle of θ, we need to know the quadrant in which θ lies.
The reference angle of θ in standard position is the acute angle between the terminal side of θ and the x-axis.
If θ is in the first quadrant, then θ' = θ.
If θ is in the second quadrant, then θ' = π - θ.
If θ is in the third quadrant, then θ' = θ - π.
If θ is in the fourth quadrant, then θ' = 2π - θ.
The measure of angle θ, we can determine its reference angle using the above rules.
The statement cos(0)=-3/10 is not related to the reference angle of θ.
It is the value of the cosine function at 0 radians or 0 degrees.
This value does not correspond to any angle that has a reference angle.
The measure of angle θ cannot determine the statements that are true about its reference angle.

A research study showed that a sample of 25 dosages from a medicine dispensing machine averaged 24.1 mg of a certain drug. The sample standard deviation was 1.8 mg. a) Form a 99% confidence interval of the population average of drug dosage dispensed. b) Explain what this interval means to someone unfamiliar with this research.
Answer:
a) The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.
b) It means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
a)
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of \(1 - \frac{1 - 0.99}{2} = 0.995\). So we have T = 2.797
The margin of error is:
\(M = T\frac{s}{\sqrt{n}} = 2.797\frac{1.8}{\sqrt{25}} = 1\)
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 24.1 - 1 = 23.1 mg
The upper end of the interval is the sample mean added to M. So it is 24.1 + 1 = 25.1 mg
The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.
b)
The interval means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.

Which function has the same range as f (x) = negative 2 StartRoot x minus 3 EndRoot + 8?
g(x) = -2√x + 8 is the function that has the same range as f(x) = -2√(x - 3) + 8. Both functions have the range of y ≤ 8
The function that has the same range as f(x) = -2√(x - 3) + 8 is g(x) = -2√x + 8. Both functions have the range of y ≤ 8.There are a few steps involved in determining which function has the same range as f(x) = -2√(x - 3) + 8. The range of a function refers to all the possible output values that the function can produce.Let's begin by examining the original function:f(x) = -2√(x - 3) + 8The square root symbol (√) implies that x-3 must be greater than or equal to 0. If x-3 is negative, then the function would produce an imaginary result.
Let's solve for x when f(x) = 0:0 = -2√(x - 3) + 8-8 = -2√(x - 3)4 = √(x - 3)16 = x - 3x = 19This tells us that the x-value that produces an output of 0 is x = 19. To determine the range, we need to find the maximum and minimum output values. We can use a graphing calculator or sketch a graph to determine the shape of the function and the range.The shape of the function suggests that the range is y ≤ 8, which means that the maximum value of the function is 8. This tells us that any function with the same maximum output value of 8 will have the same range as f(x).

12\(x^{2}\) + 15x + 4
Step-by-step explanation:
(f ° g)(x) means a composition of functions. It can also be written as f(g(x)).
This means that you are taking g(x) and plugging it into f(x) anywhere there is an x in the equation.
f(x) = 3x + 4
f(g(x)) = 3(g(x)) + 4
= 3(4\(x^{2}\) + 5x) + 4
= 12\(x^{2}\) + 15x + 4

Right triangle with a hypotenuse of 159 ft and Angle A = 34 degree
Calculate the length of the sides they should be rounded to the nearest whole foot. The rounded for the legs (side) should be used to calculate the area of the triangle
the length of side a is 91 ft (rounded to the nearest whole foot) and the length of side b is 132 ft (rounded to the nearest whole foot). The area of the triangle is approximately 6007 sq ft.
Given: The hypotenuse of the right triangle,
c = 159 ft; angle A = 34°
We know that, in a right-angled triangle:
\($$\sin\theta=\frac{\text{opposite}}\)
\({\text{hypotenuse}}$$$$\cos\theta=\frac{\text{adjacent}}\)
\({\text{hypotenuse}}$$\)
We know the value of the hypotenuse and angle A. Using trigonometric ratios, we can find the length of sides in the right triangle.We will use the following formulas:
\($$\sin\theta=\frac{\text{opposite}}\)
\({\text{hypotenuse}}$$$$\cos\theta=\frac{\text{adjacent}}\)
\({\text{hypotenuse}}$$$$\tan\theta=\frac{\text{opposite}}\)
\({\text{adjacent}}$$\) Length of side a is:
\($$\begin{aligned} \sin A &=\frac{a}{c}\\ a &=c \sin A\\ &= 159\sin 34°\\ &= 91.4 \text{ ft} \end{aligned}$$Length of side b is:$$\begin{aligned} \cos A &=\frac{b}{c}\\ b &=c \cos A\\ &= 159\cos 34°\\ &= 131.5 \text{ ft} \end{aligned}$$\)
Now, we have the values of all sides of the right triangle. We can calculate the area of the triangle by using the formula for the area of a right triangle:
\($$\text{Area} = \frac{1}{2}ab$$\)
Putting the values of a and b:
\($$\begin{aligned} \text{Area} &=\frac{1}{2}ab\\ &=\frac{1}{2}(91.4)(131.5)\\ &= 6006.55 \approx 6007 \text{ sq ft}\end{aligned}$$\)
Therefore, the length of side a is 91 ft (rounded to the nearest whole foot) and the length of side b is 132 ft (rounded to the nearest whole foot). The area of the triangle is approximately 6007 sq ft.
