First, find the circumference of the circle and divide it by 4. Then add lines AB and BC to that (these two lines are both radiuses of the circle).

P = πd/4 + 4 + 4
= π(8)/4 + 4 + 4
= 25.12/4 + 4 + 4
= 6.28 + 4 + 4
= 14.28

Therefore, the perimeter of the shaded region is 14.28.

Answer:

perimeter = 14.28

Step-by-step explanation:

Since a diameter of the circle has length 8, then a radius has length 8/2 = 4.

We have r = 4.

For a circle of radius, r, circumference = 2(pi)r.

The shaded area is a quarter circle.

Its perimeter is the length of 2 radii plus the length of a quarter circumference of the circle.

perimeter = radius (segment AB) + radius (segment BC) + arc length (arc AC)

perimeter = r + r + (1/4)(2)(pi)r

perimeter = 4 + 4 + 0.5 * pi * 4

perimeter = 14.28

On a coordinate plane, how are the locations of the points (-4 , 8) and (-4 , -8) related?
STALIN [3.7K]

Answer:

A. reflection across the y-axiss

Step-by-step explanation:

Given:

The locations of the two points are (-4 , 8) and (-4 , -8).

To find:

The relation between two points.

From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.

If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,

(x,y)→(-x,y)

For (-4,8)

(-4,8)→ (-4,-8)

So, it is reflection across the y-axis.

Therefore, the correct option is A.

Write the equation of the line that passes through (−3, 5) and (2, 10) in slope-intercept form
BigorU [14]
Slope = (10 -5)/(2+3) = 5/5=1

y = mx + b
5 = 1(-3) + b
b =8

so equation y = x +8

answer: <span>y = x + 8(first choice)</span>

15.3+x=1.3-x so how do I solve it
anzhelika [568]

Answer:

-7

Step-by-step explanation:

Let's try getting rid of the numbers to isolate the x.

Add x on both sides to get rid of the x on the right side and to get 2x on the left side. This leaves us with 15.3 + 2x = 1.3

Subtract 15.3 on both sides to get rid of the 15.3 on the left side.

This would leave us with 2x = -14

Divide 2 on both sides to isolate the x.

The answer is x = -7
