In circle R with QRS=90 and QR= 3 units find the length of arc QS round to the nearest hundredth
luda_lava [24]

Hello, I Am BrotherEye

Answer:

27.92 units

Step-by-step explanation:

Radius (qr) = r = 16 units

<QŘS = θ = 82°

Length of an arc = (Θ / 360) * 2πr

L = (θ / 360) *2πr

L = (82 / 360) * 2π * 16

L = 0.2777 * 100.53

L = 27.917 units

L = 27.92 unit

Best Of Luck

What is -5.3125 in The real Number System?
Irina18 [472]

Answer:

It'd be a rational number

Step-by-step explanation:

<em>Real numbers are a set of numbers containing all of the rational numbers and all of the irrational numbers. </em>

Types of numbers <u>in the rational number "section" are decimals, whole, mixed, and fraction numbers whether they are negative or positive they are rational numbers.</u>

Irrational numbers are numbers that cannot be expressed as the ratio of two integers. So they would be square root, pi and more.

Find the average rate of change of f ( x ) = 9 x 2 − 7 on the interval [ 2 , a ] . Your answer will be an expression involving a
aleksandrvk [35]

Answer:

9a + 18

Step-by-step explanation:

so the first step is to evaluate the value of f(2).

f(2) = 9(2)^2-7\\f(2)=9(4)-7\\f(2)=36-7\\f(2)=29

Now that we have this value we can use the slope formula (y2 - y1) / (x2 - x1) where y2 is f(a), y1 is 29, x2 is a, and x1 is 2

\frac{f(a)-29}{a-2}\\\\\frac{(9a^2-7)-29}{a-2}\\\frac{9a^2-36}{a-2}

Now from here we can use long division to simplify it further

9a^2/a = 9a\\9a(a-2)=9a^2-18a\\(9a^2-36)-(9a^2-18a)\\18a-36\\\\18a/a=18\\18(a-2)=18a-36\\(18a-36)-(18a-36)\\0\\\\9a+18
