A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh
NeTakaya

Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle =\dfrac{7\pi}{10}

Arc length = 33 cm

Formula for arc length :

s=r\theta

where, s is arc length, r is radius and \theta is central angle in radian.

Substitute s=33 and \theta=\dfrac{7\pi}{10} in the above formula.

33=r\left(\dfrac{7\pi}{10}\right)

Multiply both sides by 10.

330=7\pi r

Divide both sides by 7\pi.

\dfrac{330}{7\pi}= r

Put \pi=3.14

\dfrac{330}{7(3.14)}= r

15.0136= r

r\approx 15

Therefore, the radius of the circle is 15 cm.

In order for the limit of F(X) to exist at x=a, which of the following must hold true
astra-53 [7]

Answer:

A.

Step-by-step explanation:

Given: limit of f(x) exists at x = a

To choose: the correct option

Solution:

A limit is a value that a function approaches as the input approaches some value.

\lim_{x\rightarrow a}f(x)=L means that as x approaches to value a then f(x) approaches to value L.

A limit of a function f(x) exists at x = a if \lim_{x\rightarrow a^-}f(x)=\lim_{x\rightarrow a^+}f(x)=L

So, option A. is correct.

Answer: y = 1/2x - 6

Step-by-step explanation:

#4 We are going to use slope intercept form, (y = mx+b)

1. The line crossing the y-intercept at (0,-6)

2. The slope is 1/2 (increasing by 1 then over 2 --> RISE OVER RUN)

3. Make the equation: y= 1/2x - 6
