The translation moves 5 units to the left and 2 units down, so we have:
c = -5
d = -2
How to find the values of C and D?To identify the translation, let's follow a single vertex of the triangle.
The top vertex of triangle A is at (2, -3)
After a reflection about the x-axis only the y-value changes, so after the reflection the coordinates of that vertex will be:
(2, 3).
In now we apply the given translation, the new coordinates will be:
(2 + c, 3+ d)
And the coordinates of this vertex on triangle B is (-3, 1), so we have:
(2 + c, 3+ d) = (-3, 1)
2 + c = -3
c = -3 - 2 = -5
3 + d = 1
d = 1 - 3
d = -2
So the translation is defined by the values:
c = -5
d = -2

Answers
EXPLANATION
Given the line on the graph, we need to find the slope and the y-intercept.
Considering two ordered pairs, as for instance (x₁,y₁)=(50,-90) and (x₂,y₂)=(80,90)
The slope-equation is:
[tex]\text{Slope}=\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]Replacing terms:
[tex]\text{Slope}=\frac{(90-(-90))}{(80-50)}=\frac{180}{30}=\frac{18}{3}=6[/tex]The point-slope form of the line is:
y-y₁= m(x-x₁)
Finally, we need to represent as a point-slope form considering either one ordered pair, as for instance, (x₁,y₁)=(50,-90)
y-(-90) = 6(x-50) [Simplifying terms]
y + 90 = 6(x-50) [ANSWER]
suppose a batch of metal shafts produced in a manufacturing company have a standard deviation of 1.5 and a mean diameter of 205 inches. if 79 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would differ from the population mean by less than 0.3 inches? round your answer to four decimal places.
Answers
The probability that the mean diameter of the sample shafts would vary from the population mean by less than 0.3 inches exists 0.0757.
How to estimate population mean?Let X the random variable that represent the diameters of interest for this case, and for this case we know the following info
Where [tex]$\mu=205$[/tex] and [tex]$\sigma=1.5$[/tex]
Let the probability be
[tex]$P(205-0.3=204.7 < \bar{X} < 205+0.3=205.3)$$[/tex]
For this case they select a sample of n = 79 > 30, so then we have enough evidence to utilize the central limit theorem and the distribution for the sample mean can be approximated with:
[tex]$\bar{X} \sim N\left(\mu, \frac{\sigma}{\sqrt{n}}\right)$$[/tex]
To simplify this problem is utilizing the normal standard distribution and the z score given by:
[tex]$z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}$$[/tex]
To find the z scores for each limit and we got:
[tex]$z=\frac{204.7-205}{\frac{1.5}{\sqrt{79}}}=-1.778$$[/tex]
[tex]$z=\frac{205.3-205}{\frac{1.5}{\sqrt{79}}}=1.778$$[/tex]
To find this probability:
P(-1.778 < Z < 1.778) = P(Z < 1.778) - P(Z < -1.778)
simplifying the above equation, we get
= 0.962 - 0.0377
= 0.9243
The interest exists the probability that the mean diameter of the sample shafts would vary from the population mean by more than 0.3 inches utilizing the complement rule we got:
P = 1 - 0.9243 = 0.0757
The probability that the mean diameter of the sample shafts would vary from the population mean by less than 0.3 inches exists 0.0757.

Using linear functions, it is found that:

b) The equations are:
Point - slope form: y - 5 = -(x - 1).Slope - intercept form: y = -x + 6.c) The systems are consistent independent.
d) The point of intersection is (1, 5).
Linear functionA linear function is defined in slope-intercept formula by the rule presented as follows:
y = mx + b.
In which:
m is the constant rate of change of the function, called slope.b is the value of y when x = 0, called intercept.For Sidewalk 1, it is found that:
When x increases by 2, y increases by 4, hence the slope is of m = 2.When x = 0, y = 3, hence the intercept is of b = 3.Then the rule is:
y = 2x + 3.
For Sidewalk 2, when x changes by 2, y decays by 2, hence the slope is:
m = -2/2 = -1.
The line goes through point (1,5), hence the equation in point-slope form is:
y - 5 = -(x - 1).
Combining the like terms, the slope-intercept form is:
y - 5 = -x + 1
y = -x + 6.
Since the two lines have different slopes, the system is consistent independent.
The x-coordinate of the intersection is:
-x + 6 = 3 + 2x.
3x = 3
x = 1.
The y-coordinate is:
-x + 6 = -1 + 6 = 5.
Hence the intersection point is:

from the question, we were told in 1995, Charter charged a flat rate of
$39.95 for the first twenty hours.
and an additional per hour charge of $5.99
if,
for 20 hours = 39.95
therefore for 1 hour = 39.95/20
so for 18 hours = 39.95/20 X 18.95/20
so for 18 hours = 9
so,
to get the amount Charter bill for 18 hours in 1995 is,

A. The slope of the function = 1.5.
a = 15; b = 3; c = 3; d = 1.5
B. y-intercept (b) = 7.5
C. The equation of the function is: y = 1.5x + 7.5.
The height in 10 years is approximately 17.5 feet.
How to Write the Equation of a Linear Function?The equation of a function can be expressed as y = mx + b, if we know the value of the slope, m, and the value of the y-intercept, b.
Part A:
Using the two points on the graph, we can find the slope of the function as shown below:
The two points are (3, 12) and (5, 15):
Slope of the function = (15 - 12)/(5 - 3)
= 3/2
Slope (m) = 1.5.
Thus, the values that represents each letters would be:
a = 15; b = 3; c = 3; d = 1.5
Part B: The y-intercept of the function
The y-intercept of the function can be defined as the initial tree height which is the point where the line intercepts the y-axis of the graph.
Substitute m = 1.5 and (x, y) = (3, 12) into y = mx + b to find the y-intercept (b) of the function:
12 = 1.5(3) + b
12 = 4.5 + b
12 - 4.5 = b
7.5 = b
b = 7.5
y-intercept (b) = 7.5
Part C: To write the equation of the function, substitute m = 1.5 and b = 7.5 into y = mx + b:
y = 1.5x + 7.5.
Therefore, the initiate tree height is 7.5 feet, and it increases at a rate of 1.5 feet per year.
To find the height in 10 years, substitute x = 10 into the equation of the function, y = 1.5x + 7.5:
y = 1.5(10) + 7.5
y = 10 + 7.5
y = 17.5 feet

The slope of line through points (-2, 2) and (-4, -1) is 3/2 by using the slope-point formula that tells that change in y divided by change in x.
What is slope?A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
What is point?A point is a basic concept in classical Euclidean geometry that represents an exact location in space and has no length, width, or thickness. In contemporary mathematics, a point more broadly refers to a component of a set known as a space.
Here,
The points are (-2, 2) and (-4, -1)
m=(y2-y1)/(x2-x1)
m=Δy/Δx

I have two cans of paint. Can a has 9 parts of blue paint to one part of yellow paint. Can b is 20 percent blue paint and the rest is yellow paint. How much paint should i use from each can to obtain 9 liters of paint which is half blue and half yellow.
Answers
The amount of paint that must be used from can A and can B is 3.86 liters and 5.14 liters respectively to obtain 9 liters of paint which is half blue and half yellow.
Can A has 9 parts of blue paint and 1 part of yellow paint, this can be expressed in percentage as;
Can A = 90% blue, 10% yellow
Similarly,
Can B = 20% blue, 80% yellow
Now consider an algebraic expression as follows;
A + B = 9 liters
90% A + 20% B = 50% [Blue]
10% A + 80% B = 50% [Yellow]
Resolving;
90% A + 20% B = 10% A + 80% B
80% A = 60% B
Solving the equation, A + B = 9, for one variable;
A + B = 9
B = 9 - A
80% A = 60% (9 - A)
80% A = 540% - 60% A
140% A = 540%
A = 3.86 Liters
Now solving for B;
B = 9 - A
B = 9 - 3.85
B = 5.14 Liters
Therefore 3.86 liters should be used from can A and 5.14 liters should be used from can B.

Answers
EXPLANATION
Since we know that the number of hours is represented by a periodic function, the appropriate model is the sine function.
As the average number of daylight hours is 12 with a maximum and minimum of 14.4 and 9.6 respectively.
Furthermore, the period is 365.
Thus, the period is as follows:
[tex]\frac{2\pi}{365}=0.017[/tex]The appropiate model is the following:
[tex]H(t)=a\sin(0.017t)+12[/tex]Now, we need to compute the value of a:
Since the sine function reaches its highest value at t=90° and is represented by 14.4, when t=90°, the value of the function is asin(0.017t) = 1
Therefore,
14.4 = a + 12
Subtracting -12 to both sides:
14.4 - 12 = a
Subtracting numbers:
2.4 = a
In conclusion, the final function is the following:
[tex]H(t)=2.4\sin(0.017t)+12[/tex]Since the minimum is at t=0, we want:
[tex]H\left(t\right)=-2.4cos\left(0.017t\right)+12[/tex]In conclusion, the solution is the OPTION C)

Will the ball sail over the tree? If yes, by how much? If not, by how much?
Answers
a) We will draw the situation.
b) Considering the theory, the vertex of a parabola is represented in (h,k) where h is the x-coordinate, in this case, if our parabola has an amplitude of x=320feet then h=320/2=160feet, and k is the highest y-coordinate 80 feet. So the equation is:
[tex]\begin{gathered} y=a(x-h)^2+k \\ y=a(x-160)^2+80 \end{gathered}[/tex]We have to know the value for a, so we will use a point to replace it in the equation and with that, we will know the value, so in x=0 the y-value is 0 too so:
[tex]\begin{gathered} 0=a(0-160)^2+80 \\ a(-160)^2=-80 \\ a=-\frac{80}{25600}=-\frac{1}{320} \end{gathered}[/tex]So the equation is:
[tex]y=-\frac{1}{320}(x-160)^2+80[/tex]c. To know the answer to this question we will have to replace x=280feet with the y value we will know if at the moment the ball can go over the tree or if it would crash into it.
[tex]\begin{gathered} y=-\frac{1}{320}(280-160)^2+80 \\ y=35feet \end{gathered}[/tex]At that point, the ball would be 35 feet up so if it could pass over the tree 5 feet higher.

Answers
Answer:
B. −0.37; This indicates that the line of best fit is accurate and is an overall good model for prediction.Step-by-step explanation:
y = 0.81x + 6.9
residual value = Measured value - Predicted value
Measured value = actual y-coordinate of the point, y
Predicted value = value of y from the equation, y1
residual value = (actual y-coordinate of the point, y) - (value of y from the equation, y1)
residual value = y - y1
x y y1 residual (y-y1)

Sum of residuals:
sum = (-0.33) +(-2.76)+(2.05)+(0.43)+(2.62)+(-2.38)
sum of residuals = -0.37ANSWER:
B. −0.37; This indicates that the line of best fit is accurate and is an overall good model for prediction.
(Though not very accurate as it should have been if the sum of residuals was equal to 0).
A total discrepancy of -0.37 is not too bad.

Solve each system of the new equations by adding or subtracting
Answers
Given the equations
x + y = 5----------------------(1)
x - 3y = 3-----------------------(2)
Subtract equation (2) from (1)
x - x -3y - y = 3 - 5
-4y = -2
Divide both -4
[tex]\begin{gathered} \frac{-4y}{-4}\text{ = }\frac{-2}{-4} \\ y\text{ = }\frac{1}{2}\text{ = 0.5} \\ \end{gathered}[/tex]Substitute y = 1/2 into equation (1)
x + y = 5
[tex]\begin{gathered} x\text{ + }\frac{1}{2}\text{ =5} \\ x\text{ = 5 -}\frac{1}{2} \\ x\text{ = }\frac{10-1}{2} \\ x=\frac{9}{2}\text{ = 4.5} \\ \end{gathered}[/tex]Hence, the solution to the equations is
[tex]\begin{gathered} x\text{ = }4.5,\text{ y = 0.5} \\ Or\text{ in coordinate form, (4.5, 0.5)} \end{gathered}[/tex]suppose that a tall child with arm span 120 cm and height 118 cm was added to the sample used in this study. what effect will this addition have on the correlation and the slope of the least-squares regression line?
Answers
A tall child with an arm span of 120 cm and height of 118 cm was added to the sample used in this study then the correlation will increase whereas the slope stays the same.
Correlation is a relation between two variables, by shifting one independent variable, how the dependent variable will shift, that's the degree of correlation since Correlation can be fitted in any shape or condition. It can be fitted nonlinear, straight or curvy straight, etc whereas slope is related to a straight variety of two variables, it is characterized as the rate of altering of the dependent variable in order with the independent variable. By and large you'll discover equation incline =( y2-y1)/(x2-x1).

Identify the rule for fg when f(x) = –3x – 6 and g(x) = x2 – x – 6.
Answers
The rule for the given function f /g when the function f(x) = -3x -6 and
g(x) = x² -x - 6 is identified as f(x) / g(x) = -3 / (x -3).
As given in the question,
Given function are:
f(x) = -3x -6
g(x) = x² -x - 6
Rule to identify for the function f(x) / g(x) we get,
Substitute the value of f(x) and g(x) in the required rule we have,
f(x) / g(x) = (-3x -6 ) / ( x² -x - 6 )
Now simplify the function to get the rule:
f(x) / g(x) = -3(x+2) / (x² -3x +2x -6)
⇒ f(x) / g(x) = -3(x+2) /(x-3)(x+2)
⇒ f(x) / g(x) = -3 / (x-3)
Therefore, the rule for the given function f /g when the function f(x) = -3x -6 and g(x) = x² -x - 6 is identified as f(x) / g(x) = -3 / (x -3).
