A regular octagon is mapped onto itself every time it is rotated.

Answer:

sample response: Since both points have the same x-coordinate, the line would be vertical. A vertical line has no slope because the run of the graph, which is the denominator, is zero and therefore an undefined fraction.

Step-by-step explanation:

Answer:

y = -2x - 4.

Step-by-step explanation:

The points marked are (-2,0) and (0,-4).

The slope of line =  (-4-0) / (0- -2)

= -4/2 = -2.

The y-intercept is at y = -4,

so the equation required is y = -2x - 4.

Answer:

y = - 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line

m = \(\frac{-4-0}{0+2}\) = \(\frac{-4}{2}\) = - 2

The line crosses the y- axis at (0, - 4) ⇒ c = - 4

y = - 2x - 4 ← equation of line

Answer:

6 weeks

Step-by-step explanation:

So the amount b we will have in our account w weeks from now is given by the equation:

\(b=85+(15+7)w\)

To find out after how many weeks from now we will have $210, substitute 210 for b and solve for w:

\(210=85+(15+7)w\)

Subtract 85 from both sides:

\(125=(15+7)w\)

Add within the parentheses:

\(125=22w\)

Divide both sides by 22:

\(w=125/22\approx5.68\approx6\)

In other words, we will have $210 after approximately 6 weeks.

What is fraction ?

A fraction is a numerical representation of a part of a whole or a ratio between two quantities. It is written as a pair of numbers, one above the other, separated by a horizontal line called a fraction bar.

The number above the fraction bar is called the numerator, which represents the number of parts being considered. The number below the fraction bar is called the denominator, which represents the total number of equal parts that make up the whole.

According to the question:
The expression we're given is:
23/5 ? 4(3/5)

We need to fill in the blank with one of the symbols <, >, or = to make the expression true.

To compare fractions, we can cross-multiply and compare the resulting numerators.

Let's start by simplifying 4(3/5) to an improper fraction:
4(3/5) = (4*5 + 3)/5 = 23/5

So, our expression becomes:

23/5 ? 23/5

To make this expression true, we need to fill in the blank with the symbol =, since 23/5 is equal to 23/5:
23/5 = 4(3/5)

Therefore, the correct symbol to fill in the blank is =.

The Null Hypothesis: The mean examination score for the new freshman applications is equal to 950.

The Alternative Hypothesis: The mean examination score for the new freshman applications is not equal to 950.

The Standard Error of the mean = 9.83

The Test Statistic = -1.62

The p-value = 0.106

Using alpha = .05, the outcome of a hypothesis test is to fail to reject the null hypothesis. The p-value of 0.106 is greater than the level of significance, which means that we fail to reject the null hypothesis at the 0.05 level of significance.

The 95% confidence interval estimate of the population mean examination score is 931.67 to 958.33.

Using the confidence interval, we can conclude that the population mean examination score is likely to fall between 931.67 and 958.33 with 95% confidence. Since the null hypothesis is not rejected, we can assume that the mean examination score for the new freshman applications is not significantly different from the historical mean of 950.

Answer:

Thus, it is possible to erect a pole at a point p on the boundary of the park at distances 5m and 12m respectively from gates B and A.

Step-by-step explanation:

Let P be the required location of pole .

A and B are the two gates.

Let the distance of pole at p from gate be 'x' meters

i.e. PB = x m

•°• AP = (x + 7)m and AB = 13 m

•°• AP² + BP² = AB² => (x +7)² + x =13²

Rejecting x =-12, we get x = 5

•°• PB = 5m

the $64 strip loin weighs 13 lbs as purchased.

We can find the cost per pound using the unit price formula as follows:

Total Quantity = 13 lbsTotal Cost = $64Unit Price = Total Cost ÷ Total QuantityUnit Price

= $64 ÷ 13 lbsUnit Price = $4.92 per pound

Step-by-step explanation:

The value of x is 128 degrees, given that two lines intersect at 140 degrees and (x+12) degrees and one of the angles formed by the intersection is (x+12) degrees.

If two lines intersect, the angle formed at the point of intersection is 180 degrees. We are given that the intersection of the two lines creates an angle of 140 degrees. Let's call the other angle formed by the two lines "y". Then we have:

140 degrees + y = 180 degrees

y = 180 degrees - 140 degrees

y = 40 degrees

Now, we are also given that one of the angles formed by the two lines is (x+12) degrees. We can set up an equation using this information:

x + 12 + y = 180 degrees

x + 12 + 40 degrees = 180 degrees

x + 52 degrees = 180 degrees

x = 180 degrees - 52 degrees

x = 128 degrees

Therefore, the value of x is 128 degrees.

The area of the trapezoid is 12 sqrt(39) square centimeters.

To find the area of a trapezoid, you need to use the formula:

Area = (a + b) * h / 2

where a and b are the lengths of the parallel sides, and h is the height or perpendicular distance between them.

In this case, we have three sides of the trapezoid given as 8 cm, 5 cm, and 16 cm. However, we do not know which sides are parallel, so we cannot directly calculate the area.

To find the parallel sides, we can use the fact that opposite sides of a trapezoid are equal in length. Since 5 cm is not equal to either 8 cm or 16 cm, we know that the 5 cm side is not parallel to either of the other two sides. Therefore, the parallel sides must be the 8 cm and 16 cm sides.

Next, we need to find the height or perpendicular distance between the parallel sides. To do this, we can draw a line segment from the 5 cm side to the line connecting the parallel sides. This line segment is perpendicular to both the 5 cm side and the line connecting the parallel sides. The length of this line segment is the height of the trapezoid.

To find the length of this line segment, we can use the Pythagorean theorem. The 5 cm side and the height form the two legs of a right triangle, and the length of the hypotenuse is the difference between the lengths of the parallel sides, which is 16 cm - 8 cm = 8 cm. Therefore, we have:

height^2 + 5^2 = 8^2

height^2 = 39

height = sqrt(39) cm

Now that we know the lengths of the parallel sides and the height, we can plug these values into the formula for the area:

Area = (8 cm + 16 cm) * sqrt(39) cm / 2

Area = 24 cm * sqrt(39) cm / 2

Area = 12 cm * sqrt(39) cm

Therefore, the area of the trapezoid is 12 sqrt(39) square centimeters.

254/324 which is about 78.4%

Step-by-step explanation:

found area of entire square to be 18² or 324

found area of 4-quarter circles - which equals one circle with radius of 9

A = 81π which is about 70

subtracted 324 and 70 to get 254

ratio of shaded to unshaded is 254 : 324

The Probability of point to lie is in the shaded region= \(\frac{254.34}{324}\)

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Area of square=  side x side

                        = 18 x 18

                        = 324 sq. cm.

Area of 4 quadrant =4 x  \(\frac{\pi r^{2} }{4}\)

                                = \(3.14 * 9 * 9}\)
