What are the resulting coordinates of triangle X′Y′Z′ after rotating triangle XYZ counterclockwise 90° about the origin? Question options:
A) X′ (1, 1), Y′ (1, 4), Z′ (–4, 4)
B) X′ (1, 1), Y′ (4, 1), Z′ (4, 4)
C) X′ (1, 1), Y′ (1, 4), Z′ (4, 4)
D) X′ (–1, 1), Y′ (1, 4), Z′ (4, –4)

Answers

Answer:

Step-by-step explanation:

Rotation 90 degrees counter clockwise rule (x,y) -----> ( -y , x )

In order to find the answer we must first find the coordinates of the pre image

The coordinates are...

x (1,-1)

y (4,-1)

z (4,-4)

Now we apply the rule stated previously

( The rule explanation: the x and y values swap and the y values sign changes. So if the y value was previously positive, after a 90° counter clockwise rotation, the y value will then be negative)

x (1,-1) -----> swap x and y values ( -1,1) ------> flip sign of new x value ( 1 , 1 )

y (4,-1) ------> swap x and y values ( -1,4) -----> flip sign of new x value ( 1 , 4 )

z (4,-4) -----> swap x and y values ( -4,4) ------> flip sign of new x value ( 4,4)

the new coordinates are X' (1,1) , Y' (1,4) , Z (4,4)

Hence the answer is C

find the area of the kite.

A. 27 square units
B. 40 square units
C. 18 square units
D. 36 square units

Answers

Answer:

36 unit^2.

Step-by-step explanation:

The area is the sum of the 2 triangles with each having base between the points (-2,4) and (-2,-4).

The base is4 - -4 = 8.

Area of a triangle = 1/2 * base * height.

Area of the kite = 1/2 * 8 * 3 + 1/2 * 8 * 6

= 12 + 24

= 36.

Answer:

Table 1(red)

Step-by-step explanation:

A proportional relationship will have a constant of proportionality between y and x all through the data given.

Constant of proportionality, k = y/x

Table 1 (red):

y/x = 5/1 = 10/2 = 20/4 = 5

k = 5 all through, therefore, this table show a proportional relationship between x and y

Table 2 (blue):

y/x = 1/6 ≠2/9 ≠ 4/15

This doesn't have a constant of proportionality, k, that is the same all through in the given table of values. Therefore, it doesn't show any proportional relationship between x and y

In the diagram, point C represents the center of the sphere. Diego says that the part of the sphere labeled D is the radius. Gregoire says that the part of the sphere labeled D is the diameter of the sphere.

A sphere. C is the center and D is the diameter.
Who is correct and why?
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Gregoire is correct; the diameter is a chord that is from the center to the surface of the sphere.
Diego is correct; the radius is a chord that passes through the center of the sphere.
Diego is correct; the radius is a chord that is from the center to the surface of the sphere.

Answers

Answer:A

Step-by-step explanation: edg 2021

Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.

What is a sphere?

It is a three-dimensional figure where the volume is given as 4/3 πr³

We have,

The diameter of a sphere is a chord that passes through the center of the sphere and has endpoints on the surface of the sphere.

Therefore, the part of the sphere labeled D in the diagram is the diameter, not the radius.

The radius of a sphere is a chord that is from the center to the surface of the sphere, and it is half the length of the diameter.

Thus,

Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.

A rectangle has a a perimeter of 68 ft. The length and width are scaled by a factor 1.5.

The perimeter of the resulting rectangle is ___ ft.

Answers

Answer and Step-by-step explanation:

Answer and Step-by-step explanation:

Here is the equation for finding the sides (just to show):

68 = (2L + 2W)

We multiply L and W by 2 because there are two of the lengths and 2 of the widths.

Now, we add the scale factor to the outside, but on both sides of the equation.

68 × 1.5 = 1.5(2L + 2W)

Multiply 68 by 1.5.

102 = 1.5(2L + 2W)

The answer is 102.

The perimeter of the resulting rectangle is 102 ft.
