Answer: y = -4
Step-by-step explanation:
Based on these three given points, we can tell that this line is a horizontal line because there is no slope. All of the points have the same y-value, -4.
This means the equation of the line is:
y = -4
See attached for a visual representation. I have graphed the given points over the top of the equation we wrote for the line.
what are the coordinates of each point after quadrillateral MNPQ is trans;ated 2units right and 5 units down
The coordinates of each point after the quadrilateral MNPQ is translated 2 units right and 5 units down are:
M' = (x1 + 2, y1 - 5)
N' = (x2 + 2, y2 - 5)
P' = (x3 + 2, y3 - 5)
Q' = (x4 + 2, y4 - 5)
How to calculate the coordinates?To calculate the coordinates, we shall assume that the coordinates of the points of the quadrilateral MNPQ are:
M = (x1, y1)
N = (x2, y2)
P = (x3, y3)
Q = (x4, y4)
Next, we translate the quadrilateral 2 units right and 5 units down by adding 2 to the x-coordinate and subtracting 5 from the y-coordinate of each point.
The new coordinates of the points after the translation will be:
M' = (x1 + 2, y1 - 5)
N' = (x2 + 2, y2 - 5)
P' = (x3 + 2, y3 - 5)
Q' = (x4 + 2, y4 - 5)
Therefore, the coordinates of each point after the quadrilateral is translated 2 units right and 5 units down are:
M' = (x1 + 2, y1 - 5)
N' = (x2 + 2, y2 - 5)
P' = (x3 + 2, y3 - 5)
Q' = (x4 + 2, y4 - 5)

cot0 equals 6, lies in quadrant 3 sin20
The exact value of sin 2θ is 12/37
How to find the exact value of sin 2θ?Trigonometry deals with the relationship between the ratios of the sides of a right-angled triangle with its angles.
We have:
cot θ = 6
Thus, tan θ = 1/6
Using the given information, we can sketch the location of the angle θ in the quadrant (See the attached image).
Thus, we can calculate the value of the hypotenuse using the Pythagoras theorem. That is:
hypotenuse = √((-6)² + (-1)²) = √37
sin θ = -1/√37
cos θ = -6/√37
Using trig. identity:
sin 2θ = 2sinθ·cosθ
sin 2θ = 2 * (-1/√37) * (-6/√37)
sin 2θ = 12/37
Therefore, the exact value of sin 2θ is 12/37

Write the domain using interval notation.
Answer:
[tex](f \circ g)(\text{x}) = \frac{13}{13-\text{x}}[/tex]
Domain: [tex](-\infty,0) \cup (0,13) \cup (13,\infty)[/tex]
=================================================
Explanation:
Let's find the function composition.
The notation [tex](f \circ g)(\text{x})[/tex] is the same as [tex]f(g(\text{x}))[/tex]
[tex]f(\text{x}) = \frac{\text{x}}{\text{x}-1}\\\\\\f(g(\text{x})) = \frac{g(\text{x})}{g(\text{x})-1}\\\\\\f(g(\text{x})) = g(\text{x}) \div \Big( g(\text{x}) - 1\Big)\\\\\\[/tex]
Then,
[tex]f(g(\text{x})) = \frac{13}{\text{x}} \div \left(\frac{13}{\text{x}}-1}\right)\\\\\\f(g(\text{x})) = \frac{13}{\text{x}} \div \left(\frac{13}{\text{x}}-\frac{\text{x}}{\text{x}}\right)\\\\\\f(g(\text{x})) = \frac{13}{\text{x}} \div \frac{13-\text{x}}{\text{x}}\\\\\\f(g(\text{x})) = \frac{13}{\text{x}} * \frac{\text{x}}{13-\text{x}}\\\\\\f(g(\text{x})) = \frac{13}{13-\text{x}}\\\\\\[/tex]
-----------------
Now let's find the domain.
If we plugged x = 0 into g(x), then we get a division by zero error.
This means we must exclude this value from the domain.
For similar reasoning, we must exclude x = 13 because we get a division by zero error in [tex]f(g(\text{x})) = \frac{13}{13-\text{x}}[/tex]
We could have any other real number to be plugged in for x.
Here's what the domain looks like in interval notation.

How many seconds does the ball reach its maximum height using the equation
h(t)= -0.2t^2 + 2t
5 seconds.
Step-by-step explanation:1. Find the "x" position of the vertex of the equation.In a function expressing altitute (h) in terms of time (t), finding the vertex will provide the time and altitute when the object reaches the maximum height. Therefore, let's use the vertex formula to see exactly when this happens:
"x" vertex value: [tex]-\dfrac{-b}{2a}[/tex]
a) For using that equation, first write the given equation on its standard form.
Standard form of quadratic equations: [tex]ax^{2} +bx+c=0[/tex]
b) You can substitute h(t) by 0 on the origina equation:
[tex]-0.2t^{2} +2t=0[/tex]
c) Idenfity the coefficients.
a= -0.2, beacuse "t²" is being multiplied by -0.2.
b= 2, beacuse "t" is being multiplied by 2.
d) Substitute in the formula and calculate.
[tex]\sf X\,value_{Vertex} =-\dfrac{-b}{2a}=-\dfrac{-(2)}{2(-0.2)}=-\dfrac{-(2)}{-0.4}=5[/tex]
2. Answer.So the "x" value of this h(t) equation is located on x= 5, therefore, the maximum point happens at x= 5. Since this is an equation that expresses altitute in terms of time, this means that 5 seconds after the object starts its movement it reaches its maximum altitute.

Showing all work solve for x and y in this special right triangle
Answer:
x = 4√3
y = 8√3
Step-by-step explanation:
The interior angles of the given right triangle are 30°, 60° and 90°.
Therefore, the triangle is a special 30-60-90 triangle.
In a 30-60-90 triangle, the measures of its sides are in the ratio 1 : √3 : 2.
Therefore, the formula for the ratio of the sides is b : b√3 : 2b where:
b is the shortest side opposite the 30° angle.b√3 is the side opposite the 60° angle.2b is the longest side (hypotenuse) opposite the right angle.From inspection of the given triangle, the side opposite the 60° angle is 12 units in length. Therefore:
[tex]b\sqrt{3} = 12[/tex]
Solve the equation for b:
[tex]\begin{aligned}b&=\dfrac{12}{\sqrt{3}}\\\\b&=\dfrac{12 \cdot \sqrt{3}}{\sqrt{3} \cdot \sqrt{3}}\\\\b&=\dfrac{12\sqrt{3}}{3}\\\\b&=4\sqrt{3}\end{aligned}[/tex]
"x" is the side opposite the 30° angle. Therefore:

A printer is printing photos. For every 6 photos, the printer takes 3 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
We can start by finding the rate at which the printer is printing photos. Since it takes 3 minutes to print 6 photos, we can calculate the rate as 6 photos / 3 minutes = 2 photos/minute. This means that for every minute that passes, the printer prints 2 photos.
Now that we know the rate, we can use it to find out how long it will take to print 16 photos. Since the rate is 2 photos/minute, we can set up an equation to solve for y (time) when x (photos) is 16: 2 = 16/y. Solving for y, we get y = 16/2 = 8.
Therefore, when x (photos) is 16, y (time) is 8 minutes. This means that it will take the printer 8 minutes to print 16 photos.
If y (time) is 5 minutes, we can use the rate we calculated earlier to find out how many photos the printer will print in that time. Since the rate is 2 photos/minute, we can multiply it by the time to find out how many photos will be printed: 2 photos/minute * 5 minutes = 10 photos.
Therefore, if y (time) is 5 minutes, the printer will print 10 photos.
If y (time) is 7 minutes, we can use the rate we calculated earlier to find out how many photos the printer will print in that time. Since the rate is 2 photos/minute, we can multiply it by the time to find out how many photos will be printed: 2 photos/minute * 7 minutes = 14 photos.
Therefore, if y (time) is 7 minutes, the printer will print 14 photos.
The answer is B I just don't know the percentage.
The correct choice is: B. The statement is false because the reference values for the decrease and increase are not the same. The true improvement over the past two years is 8.56%.
What is a percentage?In Mathematics, a percentage can be defined as any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.
Mathematically, percentage increase can be calculated by using this mathematical equation (formula):
Percentage increase = [Final value - Initial value]/Initial value × 100
Based on the information provided about the high school test scores, we have the following:
True improvement = (100% - 8%) × (100 + 18)
True improvement = (92%) × (100 + 18)
True improvement = (0.92) × (118)

A researcher claims that the proportion of smokers in a certain city is less than 20%. To test this claim, a random sample of 700 people is taken in the city and 150 people indicate they are smokers.
The following is the setup for this hypothesis test:
H0:p=0.20
Ha:p<0.20
In this example, the p-value was determined to be 0.828.
Come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%)
Answer:
Based on the hypothesis test conducted with a significance level of 5%, we fail to reject the null hypothesis that the proportion of smokers in the city is 20%. This means that we do not have sufficient evidence to conclude that the proportion of smokers is less than 20%. The p-value of 0.828 suggests that there is a high probability that the observed proportion of smokers in the sample is due to chance and not a true difference in the proportion of smokers in the population. Therefore, we cannot conclude that the city has a lower proportion of smokers than 20%.
In this hypothesis test set up by the researcher, the p-value is 0.828, which is greater than the significance level (0.05). Therefore, we do not reject the null hypothesis, meaning there is not enough statistical evidence to validate the researcher's claim that the proportion of smokers is less than 20%
Explanation:A hypothesis test in statistics uses test statistics based on sample data to accept or reject a null hypothesis. In this scenario, the null hypothesis (H0) states that the proportion of smokers (p) is 20%. The alternative hypothesis (Ha) claims that the proportion of smokers is less than 20%. The p-value is a measure of the probability that the observed data could occur under the null hypothesis. In our case, a p-value of 0.828 means that there is an 82.8% chance of observing the data if the true proportion of smokers is 20%, or higher.
Usually a threshold known as the significance level (in this case 5% or 0.05) is used to determine whether the null hypothesis should be rejected or not. If the p-value is less than or equal to the significance level, it suggests that the observed data is inconsistent with the null hypothesis, and the null is usually rejected. However, since our p-value is greater (0.828 > 0.05), we would not reject the null hypothesis, suggesting that there is not enough evidence to support the researcher's claim that the proportion of smokers is less than 20%.
Therefore, the conclusion is that the researcher's claim cannot be validated using the provided data.

Use the unit circle to find exact value of the trig function

write the standard equation of a circle with its centre in the fourth quadrant tangent to x=7, y=-4 and x=17
Answer:
Step-by-step explanation:
To write the standard equation of a circle with its center in the fourth quadrant tangent to x=7, y=-4 and x=17, we can first find the center of the circle.
Since the center is in the fourth quadrant and tangent to x=7, y=-4 and x=17, the center must lie on the line x=12 (the midpoint between 7 and 17) and y=-4 (the point of tangency).
So the center of the circle is (12, -4).
Next, we need to find the radius of the circle. Since the circle is tangent to x=7 and x=17, the radius is the distance from the center to either x=7 or x=17.
The radius is thus 12 (the difference between 12 and 7) or 5 (the difference between 12 and 17).
So the standard equation of the circle is:
(x - 12)^2 + (y + 4)^2 = 25

The function limit of f(x) as x approaches 2 is 67 and the limit of f²(x) as x approaches 2 is 4489.
The function f(x) can be rewritten as:
f(x) = (5x³ + 3x² - x)/(x+2)
Using direct substitution, we see that f(2) is undefined, as the denominator of the function becomes 0.
To evaluate the limit, we can use L'Hopital's rule:
[tex]\lim_{x \to 2\[/tex] f(x) = lim x→2 (5x³ + 3x² - x)/(x+2)
= [tex]\lim_{x \to 2\[/tex] (15x² + 6x - 1)/(1)
= (15(2)² + 6(2) - 1)/(1)
= 67
To find the limit of f²(x) as x approaches 2, we can simply square the limit:
f(x) = [tex]\lim_{x \to 2\}[/tex]f²(x)

The inverse of the function f(x) = x^7 can be found by following these steps:
Step 1: Replace f(x) with y. The equation becomes y = x^7.
Step 2: Interchange x and y in the equation, so it becomes x = y^7.
Step 3: Solve the equation for y by taking the seventh root of both sides. This yields y = x^(1/7).
Therefore, the inverse function of f(x) = x^7 is g(x) = x^(1/7), which maps any given value of x to its seventh root.
It's important to note that the domain and range of the inverse function are the opposite of those of the original function. The domain of the inverse function is all real numbers, while the range is only positive real numbers. The domain of the original function is all real numbers, while the range is also all real numbers.

To find the inverse of the function f(x) = (-2/5)x^3, we can follow these steps:
Step 1: Replace f(x) with y. The equation becomes y = (-2/5)x^3.
Step 2: Solve the equation for x in terms of y.
Multiply both sides by -5/2:
(-5/2) y = x^3
Take the cube root of both sides:
x = [(-5/2) y]^(1/3)
Step 3: Replace x with f^-1(y) to obtain the inverse function.
f^-1(y) = [(-5/2) y]^(1/3)
Therefore, the inverse function of f(x) = (-2/5)x^3 is f^-1(y) = [(-5/2) y]^(1/3).
It is important to note that the domain and range of the inverse function are the opposite of those of the original function. The domain of the inverse function is all real numbers, while the range is also all real numbers. The domain of the original function is all real numbers, while the range is only negative real numbers if x is negative and only positive real numbers if x is positive.
ACTIVITY 3: Solve the following equations.
The value of x in each expressions are:
1) 6

5) -4
We have,
The expressions are:
1)
[tex]3^x = 9^3[/tex]
And,
9³ = (3²)³ = [tex]3^6[/tex]
So,
[tex]3^x = 3^6[/tex]
And,
x = 6
2)
[tex]4^{x + 1}[/tex] = 16
16 = 4²
So,
x + 1 = 2
x = 2 - 1
x = 1
3)
[tex](1/3)^x[/tex] = 27
27 = 3³
So,
[tex]3^{-1x}[/tex] = 3³
-x = 3
x = -3
4)
[tex]5^{3x}[/tex] = [tex]25^{x - 1}[/tex] =
[tex]5^{3x}[/tex] = [tex]5^{2x - 21}[/tex]
3x = 2x - 21
3x - 2x = -21
x = -21
5)
[tex]2^{-x}[/tex] = 16
16 = [tex]2^4[/tex]
So,
-x = 4
x = -4
