What is the image point of (2,4)(2,4) after a translation left 4 units and down 1 unit?

Answer:

Step-by-step explanation:

f(x) = 2x - 4

g(x) = 1/2x - 4

6)

f(4) means that wherever you see an x on the right, you put a 4.

f(4) = 2x - 4

f(4) = 2*4 - 4

f(4) = 8  - 4

f(4) = 4

7)

g(x) = 1/2x - 4

g(2) = 1/2(2) - 4

g(2) = 1 - 4

g(2) = - 3

8)

f(-5) = 2*-5  - 4

f(-5) = -10 - 4

f(-5) = -14

9)

g(-6) = 1/2 ( - 6) - 4

g(-6) = -3 - 4

g(-6) = - 7

The volume of one fish food cubes is: 1/64 ft³

Using the volume formula, the volume of the shipping box is: 15/4 × 3 × 13/4 = 585/16 ft³

The number of fish food cubes that can be packed in the shipping box is: 2,340 fish food cubes.

The volume of a box = length × width × height

A cube has equal side lengths, therefore, the volume of a cube = (side length)³ = side length × side length × side length.

We are given that the fish food cubes have side lengths of 1/4 ft. Therefore:

Volume of fish food cubes = 1/4 × 1/4 × 1/4

Volume of fish food cubes = (1 × 1 × 1)/(4 × 4 × 4)

Volume of fish food cubes = 1/64 ft³

Using the volume formula, we are given the parameters of the box as:

Length (l) = 3¾ = 15/4 ft

Width (w) = 3 ft

Height (h) = 3¼ = 13/4 ft

Therefore,

Volume of shipping box = 15/4 × 3 × 13/4

Volume of shipping box = (15 × 3 × 13)/(4 × 4) = 585/16 ft³

The number of fish food cubes that can be packed in the shipping box = volume of shipping box/volume of one fish food cube

= 585/16 ÷ 1/64

= 585/16 × 64/1

= (585 × 64)/(16 × 1)

= 37,440/16

= 2,340 fish food cubes.

The limit of the cost for a month as the number of hours approaches 10 is $55.

When a member uses the car for exactly 10 hours, the cost is covered by the $55 per month fee, which includes 10 hours of driving. Since the fee already covers the cost, there are no additional charges for those 10 hours.

To calculate the limit as the number of hours approaches 10, we consider what happens as the number of hours gets closer and closer to 10, but never reaches it. In this case, as the number of hours approaches 10 from either side, the cost remains the same because the fee already includes 10 hours of driving. Thus, the limit of the cost for a month as the number of hours approaches 10 is $55.

Therefore, regardless of whether the number of hours is slightly below 10 or slightly above 10, the cost for a month will always be $55.

Step-by-step explanation:

In this question, we are asked to determine the truth-values of two statements involving sets A and B. For each statement, we need to determine if it is true or false. If it is false, we need to provide specific counterexamples by choosing appropriate sets A and B.

a. (A\B) ⊆ A

The statement (A\B) ⊆ A is true for any sets A and B. This is because the set difference (A\B) contains elements that are in A but not in B. Therefore, by definition, every element in (A\B) is also an element of A. There are no counterexamples to this statement.

b. A^c ⊆ (AUB)

The statement\(A^c\) ⊆ (AUB) is true for any sets A and B. This is because the complement of A, denoted as \(A^c\), contains all elements that are not in A.

On the other hand, the union of A and B, denoted as (AUB), contains all elements that are in A or in B or in both.

Since the complement of A contains all elements not in A, it includes all elements in B that are not in A as well.

Therefore, \(A^c\) ⊆ (AUB) holds true for any sets A and B. There are no counterexamples to this statement.

In conclusion, both statements are true for any sets A and B, and there are no counterexamples.

Answer:

69 degrees

Step-by-step explanation:

1) Find x

The angles measured x degrees and (x-28) degrees have a sum of 180 degrees because straight lines always have a measure of 180 degrees. Knowing this, construct the equation:

\(x+x-28=180\\2x-28=180\)

Add 28 to both sides

\(2x-28+28=180+28\\2x=208\)

Divide both sides by 2

\(\frac{2x}{2}= \frac{208}{2} \\x= 104\)

Therefore, x is equal to 104 degrees.

2) Find the measure of the (x-28) degree angle

Plug x into x-28

\(x-28\\= 104-28\\= 76\)

Therefore, the measure of this angle is 76 degrees.

3) Find y

All the interior angles in any triangle will add up to 180 degrees. Knowing this, we can construct another equation:

\((2y-1)+76+y= 180\)

Open up the parentheses

\(2y-1+76+y= 180\\3y+75= 180\)

Subtract both sides by 75

\(3y+75-75=180-75\\3y=105\)

Divide both sides by 3

\(\frac{3y}{3}= \frac{105}{3} \\y=35\)

Therefore, y is equal to 35 degrees.

4) Find the measure of the (2y-1) degree angle

Plug y into 2y-1

\(2y-1\\= 2(35)=1\\= 70-1\\= 69\)

Therefore, y is equal to 69 degrees.

I hope this helps!

Answer:

Degrees = Radians x 180/π

or

Degrees = 57.2958  x radians

Step-by-step explanation:

1 radian = 180/π degrees

1 radian = 57.2958 degrees

Multiply radians by this factor of 57.2958  to get the equivalent measure in degrees

π radians = 180°

2π radians = 360° which is the number of degrees in a circle

For anything greater than 2π radians you will have to subtract 360°

For example, 7 radians using the formula is 7 x (57.2958  ) ≈ 401.07°

But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°

====================================================

Explanation:

First we make a copy of AB. Then we tack on a copy of CD onto AB. Check out the diagram below to see what I mean. The segments AB and CD glue together to form the larger segment AD. We can say AB+CD = AD. Dividing that larger segment in half will locate the midpoint and it will help us average the lengths of AB and CD. It's the visual or geometric meaning of what "average" means.

To find the midpoint of any segment, we involve the process of finding the perpendicular bisector. Recall that "bisect" means to "cut in half". The perpendicular bisector of XM is point Y, and XY is exactly half that of segment AD.

------------

Check out the diagram below.

Figure 1 is the two segments separated, and figure 2 has us glue them together to form segment AD. Segment AD is renamed to XZ. Finding the perpendicular bisector of XZ leads to point Y at the midpoint and \(\text{XY} = \frac{\text{AB+CD}}{2}\), which is shown in figure 3.

The correct option is c) Easier interpretation. One of the main advantages of simple models is their ease of interpretation. Simple models tend to have fewer parameters and less complex mathematical equations, making it easier to understand and interpret how the model is making predictions.

This interpretability can be valuable in various domains, such as medicine, finance, or legal systems, where it is important to have transparent and understandable decision-making processes.

Complex models, on the other hand, often involve intricate relationships and numerous parameters, which can make it challenging to comprehend the underlying reasoning behind their predictions. While complex models can sometimes offer higher accuracy or make more detailed predictions, they often sacrifice interpretability in the process.

Alana paid a total of $5,899.50, including the simple interest and the original loan amount.

Given information:

Loan amount (Principal): $5,700

Interest rate: 3.5%

Time: 1 year

To find the simple interest, we can use the formula:

Simple Interest = Principal * Interest Rate * Time

Simple Interest = $5,700 * 3.5% * 1

Simple Interest = $5,700 * 0.035

Simple Interest = $199.50

Now, let's calculate the total amount that Alana paid by adding the principal and the simple interest:

Total Amount Paid = Principal + Simple Interest

Total Amount Paid = $5,700 + $199.50

Total Amount Paid = $5,899.50

Therefore, Alana paid a total of $5,899.50, including the simple interest and the original loan amount.

As the sample size gets larger, the z value increases therefore we will more likely to  less likely to fail to reject the null hypothesis, thus the power of the test increases.

Statistical tests provide a mechanism for making quantitative decisions about one or more processes. The intent is to determine whether there is sufficient evidence to "reject" speculations or hypotheses about the process. If you want to keep pretending that you "believe" the null hypothesis is true, then not rejecting it can do you good. Alternatively, it may indicate that there is not yet enough data to "prove" something by rejecting the null hypothesis. A classic application of statistical testing is process control studies. Suppose a manufacturing process is interested in  a photomask with an average linewidth of 500 microns. The null hypothesis in this case is that the average linewidth is 500 microns. This statement implies the need to characterize photomasks with average linewidths much larger or  smaller than 500 microns. This leads to the alternative hypothesis that the average linewidth is not equal to 500 microns. This is a two-way substitution as it protects against substitution in the opposite direction. In other words, the line width is either too small or too large.

The probability that the first candy selected is butterscotch and the second candy is taffy can be calculated as the product of the probabilities of these two events occurring.

First, let's calculate the probability of selecting a butterscotch candy as the first candy. There are 9 butterscotch candies out of a total of 15 candies, so the probability is 9/15.Next, for the second candy to be taffy, we need to consider that one butterscotch candy has already been selected and removed from the box. Therefore, there are 14 candies remaining in the box, including 2 taffy candies. Hence, the probability of selecting a taffy candy as the second candy is 2/14.

To find the probability of both events occurring, we multiply the probabilities together: (9/15) * (2/14) = 18/210.Simplifying this fraction, we get 3/35.Therefore, the probability that the first candy selected is butterscotch and the second candy is taffy is 3/35, which is approximately 0.086 or rounded to three decimal places.

A = [5 -2]

[0 6]

To apply T to any vector x, we simply multiply it by A:

T(x) = Ax

So, if we have a vector x = [x1, x2], we can calculate T(x) as follows:

T(x) = [5x1 - 2x2, 6x2]
