Answer:

6

Step-by-step explanation:

Arc length = radius * central angle

s = rθ

A circle is 2π radians, so 1/3 of that is 2/3 π.

Given that s = 12 and θ = 2/3 π:

12 = r (2/3 π)

r = 18/π

r ≈ 6

You’re given two side lengths of 3 centimeters and 5 centimeters. Which measurement can you use for the length of the third side
mrs_skeptik [129]

Answer:

You could use a measurement of 4 centimeters.

The valid range is  2  < x < 8  cms.

Step-by-step explanation:

The third side must either be less than 3+5, that is less than 8 cms and  it must be greater than (5-3) = 2 cms. If it is any other length we could not construct a triangle.

Graph ΔABC and its image after a rotation of 180º about the origin.
ValentinkaMS [17]

Answer:

The vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5). The graph of image and preimage is shown below.

Step-by-step explanation:

From the given figure it is noticed that the vertices of  triangle ABC are A(0,0), B(1,5) and C(-4,5).

If a figure rotated at 180º about the origin, then

P(x,y)\rightarrow P'(-x,-y)

The vertices of image are

A(0,0)\rightarrow A'(0,0)

B(1,5)\rightarrow B'(-1,-5)

C(-4,5)\rightarrow C'(4,-5)

Therefore the vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5).

The graph of image and preimage is shown below.

EleoNora [17]
We want to find 9.5% of $50.

First put 9.5% in decimal form. 9.5% = 0.095.

Then multiply 0.095 by 50. 50 * 0.095 = $4.75 fee

The money Kennedy will recieve is going to be 50 dollars minus the $4.75 fee.

50 - 4.75 = $45.25 with the fee subtracted
