can someone help me with this problem? Thank you!

Answer:

20

Step-by-step explanation:

First, consider (0,2) and (8,2).  The y-value is the same for both points.  x ranges from 0 to 8, so the length of this horizontal side of the triangle is (8-0), or 8.

Again, this horiz. side has a y-value of 2.

The third point is (4,-3).  Therefore the vertical distance from the horizontal line to the third point is 2 - (-3), or 5.

Thus, the "base" of the triangle is 8 and the "height" is 5.

The area is  A = (bh)/2.  Substitute the values 8 and 5.  Simplify your result.  Answer:  20 square units.

Answer: The resulting parallelogram is congruent to the original parallelogram regardless of the order of the transformations.

Step-by-step explanation:

A reflection and a translation are both rigid motions, meaning both transformations preserve congruency.

Answer:

The resulting parallelogram is not congruent to the original parallelogram regardless of the order of the transformations.

Step-by-step explanation:

According to the Empirical Rule (68-95-99.7% Rule), approximately 68% percent of the values will be between 75 and 85.

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

Here, we had  where mean of distribution of X is [tex]\mu[/tex] and standard deviation from mean of distribution of X is [tex]\sigma[/tex].

A distribution of scores on an aptitude test is Normally distributed with a mean of 80 and a standard deviation of 5.

[tex]\mu=80\\\sigma=5[/tex]

The percentage for the interval of values between 75 and 85 has to be found out. From the 68%, the interval is,

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(80 - 5 < X < 80+ 5) = 68\%\\P(75 < X < 85) = 68\%[/tex]

Thus, according to the Empirical Rule (68-95-99.7% Rule), approximately 68% percent of the values will be between 75 and 85.

The legs of a right triangle are lengths 48cm and 55cm. So, the length of the hypotenuse is 73 cm.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

The legs of a right triangle are lengths 48cm and 55cm.

Let ABC be the right angle triangle and AB is the hypotenuse.

To find the length of the hypotenuse we will use the Pythagoras theorem,

[tex]AB^2 = BC^2 + AC^2\\\\AB^2 = 48^2 + 55^2\\\\AB^2 = 2304 +3025\\\\AB^2 = 5329\\\\AB = \sqrt{5329} \\\\AB = 73[/tex]

The area of the parallelogram is the product of length and height. Then the area of the parallelogram will be 51 square cm.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

A parallelogram has a base that is 10.2 centimeters long and a height that measures 5 centimeters.

Then the area of the parallelogram will be

Area = bh

Area = 10.2 x 5

Area = 51 square cm

A quadrilateral is defined as a closed shape and a type of polygon that has four sides, four vertices and four angles.

Now, we are told that at least  at least two pairs of consecutive sides are congruent, diagonals are perpendicular to one another.

The only quadrilaterals that fit into thus definition are square and rhombus.

Now, we are told that the quadrilateral cannot be inscribed in a circle. A square can be inscribed in a circle but not a rhombus and as such we can say that the quadrilateral with the given properties is a rhombus,

The angle OBC is 90 degrees, the equation is 18r = 144, r = 8 feet, and the length of the AB is 16 feet which is the length of the red sail in the logo.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have the figure shown in the picture with dimensions.

a) As we can see, the AOB is the diameter of the circle which is perpendicular to the CBD

So the angle ∠OBC will be a right angle.

∠OBC = 90 degree.

b) Length OE is the radius of the circle.

Let's suppose OE = r

Then in a right angle triangle OBC where ∠OBC = 90 degrees.

Applying Pythagoras theorem:

OC² = CB² + OB²

(CE + OE)² = CB² + OB²

CE = 9 ft, OE = r, CB = 15 feet, and OB = r (radius of the circle)

(9 + r)² = 15² + r²

81 + 18r + r² = 15² + r²

18r = 144

r = 8 feet

OE = r = 8 feet

c)

As the angle ∠OBC = 90 degrees, that's why the triangle OBC becomes a right angle triangle and OB⊥CB.

d)

In the circle, there is a red triangle, we can find one of the lengths of the triangle which is AB.

AB is the diameter of the circle

r = 8

Diameter AB = double the radius = 2(8) = 16 feet

AB = 16 feet

Thus, the angle OBC is 90 degrees, the equation is 18r = 144, r = 8 feet, and the length of the AB is 16 feet which is the length of the red sail in the logo.
