Answer:

The division equation used to find the width is: 45 divided by 9 equals 5.

Step-by-step explanation:

The formula for the area of a rectangle is A = lw, where A is the area, l is the length, and w is the width. We know that the length of Remy’s rectangle is 9 inches and the area is 45 square inches. We can use this information to solve for the width: 45 = 9w To solve for w, we can divide both sides of the equation by 9: 45/9 = w 5 = w Therefore, the width of Remy’s rectangle is 5 inches. The division equation used to find the width is: 45 divided by 9 equals 5.

Hope this helps.

Based on the information about the angles, the value of x is 10.

From the information, n - 2 = 43

Solving for n, we get:

n = 45

The polygon has 45 sides.

sum of interior angles = (n - 2) * 180 degrees

sum of interior angles = (45 - 2) * 180 degrees

sum of interior angles = 7560 degrees

Since the polygon is regular, all of its angles have the same measure, which we are told is (17x+2)°. Let's use this to find x:

sum of interior angles = number of angles * measure of one angle

7560 = 45 * (17x+2)

7560 = 765x + 90

7470 = 765x

x = 10

The present value of the payments that Mason would receive over five years is $37,901.

To find the present value of the payments that Mason would receive over five years, we can use the present value formula for an annuity:

PV = PMT x [1 - (1 + r)^(-n)] / r

Where we have:

PV = present value of the payments

PMT = amount of each payment ($10,000 in this case)

r = interest rate per period (10% or 0.10 in this case)

n = total number of periods (5 in this case)

Plug in the values:

PV = $10,000 x [1 - (1 + 0.10)^(-5)] / 0.10

PV = $10,000 x [1 - 0.6209] / 0.10

PV = $10,000 x 3.7901

To compare 62% and 9/20, we can convert 62% to a fraction with a denominator of 20:

62% = 62/100 = 31/50

Now we can compare 31/50 and 9/20:

31/50 = 0.62

9/20 = 0.45

Since 0.62 is greater than 0.45, we can conclude that 62% is greater than 9/20.

a) The exact solution of the exponential equation [tex]8^{1-x}=9[/tex] in terms of logarithms is:  [tex]x=1-(\frac{2}{3}\times \frac{ln(3)}{ln(2)} )[/tex]

b)  An approximation to the solution rounded to six decimal places = 0.056642

Consider the exponential equation [tex]8^{1-x}=9[/tex]

Taking ln (log to the base e) on both the sides of above exponential equation,

ln([tex]8^{1-x}[/tex]) = ln (9)

We solve this equation for x.

We know that the rule of logarithm that [tex]log(a^m)=m\times log(a)[/tex]

Using this rule we get,

(1 - x) ln(8) = ln(3²)                          ............(3² = 9)

(1 - x) × ln(2³) = 2  × ln(3)

(1 - x) × 3 × ln(2) = 2  × ln(3)

1 - x = (2/3) × (ln(3) / ln(2))

x = 1 - [(2/3) (ln(3) / ln(2))]

x = 1 - [(2/3) × 1.584963]

x = 1 - 1.056642

Step-by-step explanation:

We can solve either by cross-multiplying or by multiplying both sides by the  least common denominator, which is the product of the denominators: (5x + 7)(x - 1) in this case.

Both ways will give us the same answer, although cross-multiplying seems much simpler:

[tex]4(x-1)=5(5x+7)\\4x-4=25x+35\\4x=25x+39\\-21x=39\\x=-39/21=-13/7[/tex]

We can check our answer by plugging in -13/7 for x into the equation and see if we get the same answer on both sides:

[tex]4/(5(-13/7)+7))=5/(-13/7-1)\\4/(-65/7+7)=5/(-20/7)\\4/(-16/7)=-7/4\\-7/4=-7/4[/tex]

Reflection across y-axis: (-x, y)
Reflection across x-axis: (x, -y)

7 - Correct
8 - Correct
9 - Correct
10 - This is correct, but your work is incorrect. The formula for reflection across the y-axis is (-x, y). So, you have to take all the points and make their x-values negative. A is located at (-2, -5). -2 = x, so -(-2) = 2 because negative x negative = positive. A' is located at (2, -5), D' is not. C' = (2, 0) is correct, because C is located at (-2, 0). B' = (3, 0) is correct because B was originally at (-3, 0). D' is located at (-2, -2) because D was originally located at (2, -2). So, all you have to do is swap what you wrote for A and D next to the graph, but the graph is completely correct.
11 - Correct
12 - Your answer for 12 isn't visible. I can see you said that P is located at (3, -2) and that P' is located at (-4, -1) which is correct. This means that (x - 7, y + 1) is the correct rule for this question because 3 - 7 = -4 and -2 + 1 = -1.
13. Your answer for 13 is incorrect. This is a reflection across the x-axis, not a translation. So there should be no adding/subtracting in the rule. The formula for reflection across the x-axis is (x, -y). We can find if this graph is a reflection across the x-axis by seeing if each of the prime versions of the original coordinates are a negative y version of the original coordinates.

U is located at (-4, 4), V is located at (-2, 4), and T is located at (-5, 2).

U' is located at (-4, -4), V is located at (-2, -4), and T is located at (-5, -2).

Since U' is located at (-4, -4) and U is located at (-4, 4), the y value turned negative, meaning that U' was a reflection across the x-axis because of (x, -y). Since V' and T' have negative y values of their corresponding original coordinates, Triangle U'V'T' is a reflection over the x-axis.

So, the correct rule you should put for question 13 is (x, -y).

14 - Correct

15 - Incorrect. All y-values turned negative, meaning this is another case of reflection over the x-axis. The correct rule is (x, -y).

16 - Correct

17 - Correct

18 - Correct

19 - Correct

20 - Incorrect. This was a translation over the x-axis, because all y-values turned negative. The correct rule is (x, -y).

For example, J is located at (-1, -1). J' is located at (-1, 1). The y-value turned negative because -(-1) = 1.


--Suggestion: Keep the formulas for the reflection across the x-axis and y-axis by you while doing homework like this.

Reflection across the x-axis formula: (x, -y).
Reflection across the y-axis formula (-x, y).
Translation up/down: (x, y +/- __)
Translation right/left: (x +/-, y)

Apply these formulas to each coordinate, not just one, to see if they all match up.

Step-by-step explanation:

Think of a vertical number line with sea level being 0.  Town A is +692 ft and Town B is -7 ft.

Difference in elevation = 692 - (-7) = 699

The transformations that could be used are: D. a translation of 6 units down, a rotation, and then a reflection.

If two shapes are congruent to each other, it means they have the same shape and size. The only series of transformation that can be used to produce an image that is congruent to a preimage of a shape is either a translation, rotation, or a reflection. This therefore implies that any transformation that involves a dilation will not produce congruent images of a shape but would rather produce similar images.

Therefore, option A, B, and C, which involves dilation cannot produce quadrilateral H' that is congruent to quadrilateral H.

o determine whether there is a significant difference in weight loss between two levels of exercise program, regardless of gender, we would need to conduct a statistical hypothesis test. We would use a two-sample t-test to compare the mean weight loss between the two levels of exercise program.

The null hypothesis would be that there is no significant difference in weight loss between the two levels of exercise program, while the alternative hypothesis would be that there is a significant difference in weight loss between the two levels of exercise program.

We would then calculate the p-value, which represents the probability of observing a test statistic as extreme as the one calculated from the sample data, assuming the null hypothesis is true. If the p-value is less than the significance level (usually set at 0.05), we would reject the null hypothesis and conclude that there is a significant difference in weight loss between the two levels of exercise program.

Without knowing the data, it is not possible to determine the appropriate p-value or make a decision about the significance of the difference in weight loss between the two levels of exercise program.
