(SOMEONE PLEASE HELP ME ) A central angle in a circle has a measure of 1 radian. The length of the arc it intercepts is 3.07 in.

Naddika [18.5K]

The total circle has a measure of 2π radian, so this portion is 1/(2π) of the whole circle
the circumference of the whole circle is 2πr
1/(2π) of 2πr=3.07
r=3.07

To Enter the value of n that makes the equation: 4^5.4^n=4^8 true

irina1246 [14]

$4^2\text{ }\times4^n=4^8$

Since both sides have the same base (4), we can add the exponents

$4^{5+n}=4^8$ $5+n=8$

subtract 5 from both sides:

$5+n-5=8-5$ $n=3$

If there are 512 relation from a set A = [1,2,3] to a set B, then find number of elements in B

kramer

<u>EXPLANATION</u><u>:</u>

Given set A = { 1,2,3}

n(A) = 3

Let the n(B) be n

Total number of relations from A to B = 2^(3×n) =2^3n

According to the given problem

Total relations are = 512

⇛2^3n = 512

⇛2^3n = 2⁹

If bases are equal then exponents must be equal

⇛3n = 9

⇛n = 9/3

⇛n = 3

<h3>So, Number of elements in the set B = 3</h3>
