WILL CHOOSE BRAINLIEST!!! A is (2,2). A' is (-1,-1). Which sequence of transformations best describes this transformation?

A. Reflection across the x-axis, dilation using k-1/2
B. Rotation 80°, dilation using k=1/2

Answer:

I think it's the 2nd choice. Hopefully I got this correct :)

Step-by-step explanation:

I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.

It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.

Julia: y = 5x + 30

Kelsey: y = 15x + 10.

Answer:

[tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex]

Step-by-step explanation:

y= mx +c, where m is the slope and c is the y-intercept.

We need to find the value of m and c, which can be done by using the slope formula and by substituting a pair of coordinates respectively. Find m first before finding the value of c.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

[tex]slope = \frac{7 - ( - 4)}{5 - ( - 8)} [/tex]

[tex]slope = \frac{7 + 4}{5 + 8} [/tex]

[tex]slope = \frac{11}{13} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{11}{13} x + c[/tex]

Substitute a pair of coordinates:

When x= 5, y= 7,

[tex]7 = \frac{11}{13} (5) + c[/tex]

[tex]c = 7 - \frac{55}{13} [/tex]

[tex]c = \frac{91}{13} - \frac{55}{13} [/tex]

[tex]c = \frac{36}{13} [/tex]

[tex]c = 2 \frac{10}{13} [/tex]

Thus, the equation of the line is [tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex].

Answer:

1. Sample answer

2. Sample answer

They are already answered

Step-by-step explanation:

Answer:

Assuming the area is made up of a square and a semicircle.

Perimeter

The side length of the square = 18 ft

We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).

⇒ perimeter of the square = (3 x 18) + (18 - 12)

                                                          = 54 + 6

                                                          = 60 ft

Circumference of a circle = [tex]\pi[/tex]d (where d is the diameter)

⇒ arc length of the semicircle = 1/2 circumference

                                                  = 1/2 · [tex]\pi[/tex] · 12

                                                  = 6[tex]\pi[/tex] ft

Total perimeter = 60 + 6[tex]\pi[/tex] = 78.8 ft (nearest tenth)

Area

Area of a square = s² (where s is the side length)

⇒ area of square = 18²

                             = 324 ft²

Diameter = 2r  ⇒  r = 1/2 diameter

Area of a circle = [tex]\pi[/tex]r²  (where r is the radius)

⇒ area of the semicircle = 1/2 · [tex]\pi[/tex] · 6²

                                         = 18[tex]\pi[/tex] ft²

Total area = 324 + 18[tex]\pi[/tex] = 380.5 ft² (nearest tenth)

Answer:

there are three ( 3 ) possible outcomes that are 1,2 and 3

Typically, I would say 3. So there's always that. But it could also be 4 because your spinner could land on a line. So I would say either 3 or 4.

Answer:

Step-by-step explanation:

If you are not altering the triangle in any way and just moving it (translating), they should be the same size and shape. Thus, both triangles are similar (the same shape) and congruent (equal to each other)

The volume is a measurement of three-dimensional space that is utilized.

Let r be the radius and h be the height of the cylinder and cone. Then the volume of the cylinder will be given as,

Volume of A = π r²h cubic units                       ...1

And the volume of the cone will be given as,

Volume of B = (1/3) × r²h cubic units       ...2

From equations 1 and 2

Volume of B = 3 x volume of A

The amount of water in Glass B to equal to 3 times of the amount water in Glass A

Answer:

140.4ft^2

Step-by-step explanation:

since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.

area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2

surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

Answer:

x = 37°

x = 40°

x = 260°

Step-by-step explanation:

To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.

Question 1

[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]

Question 2

To find the bigger arc, subtract the smaller arc from 360°

⇒ 360° - 140° = 220°

[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]

Question 3

The smaller arc can also be found by subtracting the external angle from 180°

Smaller arc = 180° - 80° = 100°

[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]

[tex]160^{\circ}=x-100^{\circ}[/tex]

[tex]x=260^{\circ}[/tex]

#1

#2

Bigger Arc=360-140=220°

#3

Smaller arc=180-80=100°

Answer:

The formula that is used to determine the volume of the cylinder in terms of pi is V = πr2h cubic units where, "V", "r" and "h" are the volume, radius, and height of the cylinder. This formula of volume of the cylinder also shows its dependence on the radius and height of the cylinder.
