Here are some transformation rules. For each transformation, first predict what the image of triangle ABC will look like. Then compute the coordinates of the image.


(x, y) —-> (x -4, y -1)

A’ = ???
B’ = ???
C’ = ???


(x, y) —-> (y, x)

A’ = ???
B’ = ???

(x, y) —-> (1.5x, 1.5y)

A’ = ???
B’ = ???
C’ = ???

Based on the information in the graph, it can be inferred that Josephine must have painted 1/4 of the painting.

To find the amount (fraction) of the paint, Josephine should have painted the section marked on the image. To know how much that section is equivalent to, we must take as a reference that the entire painting would be 1.

So, if we divide the painting in half, it would be 1/2, that is, we paint 1 of 2 possible parts. However, in the case of Josephine there are 4 possible parts and she only painted one. From the above, what she should have painted was 1/4.

Answer:

1. x = 0.75

2. p = 4

3. L = 11

4. t = 42

Step-by-step explanation:

1. The price of pen is x, then

=> 6x + 24 = 28.5

=> 6x = 4.5

x = 4.5/6 = 0.75

2. p is the number of lbs

=> 2p + 50 = 58

2p = 8

p = 4

3. Perimeter = 2(L + W)

2(L + 4) = 30

A triangular fence having dimensions 2x + 3, y − 6, and 4x − 3, has a perimeter of Option D: 6x + y - 6 feet.

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

A triangular fence has measurements -

a = (2x + 3) feet

b = (y - 6) feet

c = (4x - 3) feet

The formula for perimeter of a triangle is -

Perimeter = sum of all three sides

So the equation will be -

Perimeter = a + b + c

Substitute the values in the equation -

Perimeter = (2x + 3) + (y - 6) + (4x - 3)

Perimeter = 2x + 3 + y - 6 + 4x - 3

Perimeter = 6x + y - 6

Therefore, the value for perimeter is 6x + y - 6 feet.

Answer:

the length of the edge of the cube is 5 meters

Step-by-step explanation:

The surface area of a cube can be found using the formula:

Surface Area = 6 x (side length)^2.

Since the surface area of this cube is 150 square meters, we can set up an equation to solve for the side length:

150 = 6 x (side length)^2

Dividing both sides by 6, we get:

25 = (side length)^2

Taking the square root of both sides, we find the side length:

side length = sqrt(25) = 5 meters.

So the length of the edge of the cube is 5 meters.

The new position of minute hand if it starts from 1 and turns 210°  will be at the 40 minutes mark on the clock face.

The minute hand of a clock completes a full rotation every 60 minutes, or 360°. This means that each minute on the clock face corresponds to an angle of 6 degrees. (360 divided by 60 minutes). If the minute hand starts from the 1 and turns 210 degrees, we can calculate the number of minutes it has moved by dividing 210 by 6, which gives us 35. Therefore, the new position of the minute hand will be 35 minute mark on the clock face. However, since the minute hand started at the 1, we need to add 5 minutes in the final answer.

Answer:

Step-by-step explanation:

The formula to calculate the future value of an investment with compounded interest is:

Future value = Principal * (1 + rate/compoundings per year)^(number of years * compoundings per year)

In this case, the principal is $10,000, the interest rate is 2.5%, compounded annually, and the number of years is 20. So, the future value can be calculated as follows:

Future value = $10,000 * (1 + 2.5%/1)^(20 * 1)

Future value = $10,000 * (1.025)^20

Future value = $10,000 * 1.62897526

Future value = $16,289.75

Therefore, $10,000 deposited in an account earning 2.5% interest compounded annually would be worth $16,289.75 in 20 years.

The required interior angle of 20-gon measures 162 degrees.

The interior angle measure for the n-sided polygon is given by
Interior angle measure = (n-2) x 180° / n, where n is the number of sides (or vertices) of the polygon.

Here,

To find the measure of each interior angle of a 20-gon (icosagon), we can use the formula:

For a 20-gon, n = 20. Substituting this into the formula, we get:

Interior angle measure = (20-2) x 180° / 20

= 18 x 180° / 20

The value of P(-3) is -12, Quotient is (-2x² + x - 3) and Remainder is 6.

Remainder Theorem is a method for dividing polynomials according to Euclidean geometry. This theorem states that a polynomial P(x) divided by a factor (x - a) is not really an element of the polynomial.

Given:

P(x) = -2x³-5x²-3.

Using the remainder theorem, the value of P(3) is given by:

P(-3)=  -2x³-5x²-3.

P(-3) =  -2(-3)³-5(-3)²-3

P(-3) = -2(-27) -5(-9) -3

P(-3) = -54 + 45 - 3

P(-3) = -12

As, the divisor of P(x) is (x+3).

The area of the trapezoid is approximately 42.5 square meters. So, the answer closest to this value is 38 m^2.

What is trapezoid ?

A trapezoid is a quadrilateral with at least one pair of parallel sides. In a trapezoid, the parallel sides are called the bases of the trapezoid, and the non-parallel sides are called the legs. The height of a trapezoid is the perpendicular distance between the bases.

There are several types of trapezoids, including isosceles trapezoids, where the legs are of equal length, and right trapezoids, where one leg is perpendicular to both bases. Trapezoids are commonly used in geometry and can be used to find the area of various shapes, such as triangles and rectangles.

To find the area of the trapezoid, we can use the formula:

Area = (1/2) x (sum of bases) x height

Since the trapezoid is isosceles, the length of the two parallel sides are the same. Let's call that length "x". We can use this information to set up an equation:

3 + 4 + 7 + x = 2x

Simplifying, we get:

14 + x = 2x

x = 14

So the length of both parallel sides is 14 meters.

Now we can plug in the values into the area formula:

Area = (1/2) x (3 + 14) x 5

Area = 8.5 x 5

Area = 42.5

Therefore, the area of the trapezoid is approximately 42.5 square meters. So, the answer closest to this value is 38 m^2.

I took the test and got this question correct.

The t-test yields the probability (p value) that the null hypothesis is option (B) incorrect

The p-value in a t-test represents the probability of obtaining the observed test statistic (or one more extreme) assuming that the null hypothesis is true. The null hypothesis is typically a statement of "no effect" or "no difference" between two groups being compared in the test.

Therefore, a low p-value (generally less than 0.05) indicates that the observed data is unlikely to have occurred by chance under the null hypothesis and suggests that the null hypothesis is likely to be false.

In other words, a low p-value provides evidence against the null hypothesis and in favor of the alternative hypothesis (which typically represents the hypothesis that the researchers are interested in testing).

Thus, the p-value does not directly tell us whether the null hypothesis is correct or incorrect, but rather whether the evidence supports rejecting it or not.

Therefore, the correct option is (B) incorrect

The area of the shaded region is 12.5 square inches.

First we can subtract the area of the smaller triangle from the area of the larger triangle.

The larger triangle has a base of 8 inches and a height of 5 inches, so its area is:

(1/2) * base * height = (1/2) * 8 in. * 5 in. = 20 in²

The smaller triangle has a base of 3 inches and a height of 5 inches, so its area is:

(1/2) * base * height = (1/2) * 3 in. * 5 in. = 7.5 in²

Subtracting the area of the smaller triangle from the area of the larger triangle, we get:

20 in² - 7.5 in² = 12.5 in²

Therefore, the area of the shaded region is 12.5 square inches.
