Answer:

Option A true is the answer.

Step-by-step explanation:

The given circle there are two arcs AB and CD.

Angles formed by these arcs at the center arc 30°

Formula of length of arc = r × θ

where r = radius of the circle

and θ = angle formed by arc at the center.

mAB = OA × (30°) [ By formula ]

similarly mCD = DC × (30°)

Since OA = OC = r (radii of the circle )

So mAB = mCD

Therefore, statement is true.

Option A true is the answer.

Find the distance between these points: (-3, 8) and (-5,1)
irina1246 [14]

Answer:

7.28011

Step-by-step explanation:

X1 =-3

X2 =-5

Y1 =8

Y2 =1

Distance Formula = √(X2-X1)²+ (Y2-y1)²

Step 1. calculate (X2-X1)²

(-5 - -3)2 = 4

Step 2. calculate (Y2-Y1)²

(1 - 8)2 = 49

Step 3. calculate √4 + 49

                = 7.28011

What is the magnitude of force required to accelerate a car
Drupady [299]

Answer:

8.71 x 10^3N - C

Step-by-step explanation:

Force = mass x acceleration

mass = 1.7 x 10^3 and acceleration = 4.75m/s^2

Force = 1.7 x 10^3 x 4.75 = 8075N = 8.71 x 10^3N

A parallelogram has coordinates A(1, 1), B(5, 4), C(7, 1), and D(3, -2). What are the coordinates of parallelogram A′B′C′D′ afte
saul85 [17]

Hey there! I'm happy to help!

First, we need to rotate our points 180° about the origin. To find the coordinates after such a rotation, we simply find the negative version of each number in the ordered pair, which can be written as (x,y)⇒(-x,-y).

Let's convert this below

A: (1,1)⇒(-1,-1)

B: (5,4)⇒(-5,-4)

C: (7,1)⇒(-7,-1)

D: (3,-2)⇒(-3,2)

Now, we need to translate these new points five units to the right and one unit down. This means we will add 5 to our x-value and subtract 1 from our y-value. This will look like (x,y)⇒(x+5,y-1). Let's do this below.

A: (-1,-1)⇒(4,-2)

B: (-5,-4)⇒(0,-5)

C: (-7,-1)⇒(-2,-2)

D: (-3,2)⇒(2,1)

Therefore, this new parallelogram has coordinates of A'(4,-2), B'(0,-5), C'(-2,-2), and D'(2,1)

Now you know how to find the coordinates of translated figures! Have a wonderful day! :D
