The ratio of change in angular position to change in time is defined as the angular velocity. Thus, the slope of an angular position versus time graph gives the angular velocity of the <span>object being graphed.
The rank of the given graphs can be written as follow,positive graphs are listed first.
The line B is the line with the greater positive slope.
</span><span>The line B is the line with  positive slope but is less than the slope of line B.
</span><span>The lines A,t ,and F are the lines with the zero slope.
</span>The lines D and E are parallel to each other and have same negative slope.<span />

the length of an arc of a circle is 1/5 of its circumference. if the area of the circle is346.5cm²,find the angle subtended by t
dexar [7]

Answer:

72°

Step-by-step explanation:

From the question,

Area of the circle = πr²

A = πr²................. Equation 1

Where r = radius of the circle.

⇒ r = √(A/π)............. Equation 2

Given: A = 346.5 cm², π = 3.14

r = √(346.5/3.14)

r = √(110.35)

r = 10.5 cm.

Therefore,

circumference of the circle = 2πr = 2×3.14×10.5

circumference = 65.94 m

If the length of the arc(s) is 1/5 of its circumference.

Therefore, length of arc (s) = 13.188

⇒ length of arc/circumference = 13.188/65.94 =  1/5

s/2πr = θ/360

Where θ = angle substends at the center of the circle

1/5 = θ/360

θ = 360/5

θ = 72°

Solve this problem 8x + 4(x-1)<br> a. 32x+3<br> b. 12x-4<br> c. 12x+4<br> d. 9x-4
Lilit [14]

Answer:

b

Step-by-step explanation:

8x +4(x -1)

<em>Expand by multiplying 4 into each term inside the bracket:</em>

= 8x +4(x) +4(-1)

= 8x +4x -4

<em>Simplify</em>

= 12x -4

Thus, the answer is b.

Find the value of w<br> A. 141<br> B. 110<br> C. 80<br> D. 100
saw5 [17]

Answer:

141

Step-by-step explanation:

Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)

We know z+70 = 180 since they form a straight line

z = 110

z = 1/2 ( 79+w)

110 = 1/2 ( 79+w)

220 = 79+w

220-79 = w

141 =w
