The radian measure of central angle is 0.8 radians
<em><u>Solution:</u></em>
Given that we have to find the radian measure of central angle
From given figure in question,
Arc length = 60 units
Radius = 75 units
<em><u>The radian measure of a central angle θ of a circle is given as:</u></em>
Where,
"r" is the radius of circle
"s" is the length of arc
= central angle in radians
<em><u>Substituting the known values,</u></em>
Thus radian measure of central angle is 0.8 radians
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
Answer:
identity property of addition-
a+0=a
identity property of multiplication-
a*1=a
Step-by-step explanation:
i cant give u an exact answer as u didnt give Micheals answers so i just gave some examples about what addition and multiplication identity property should look like. Identity property's concept is to keep the same identity. Basically, "a" shouldnt change. In addition, to keep a the same all u hv to do is add 0 as anything plus 0 is the same. for multiplication, just multiply by 1. Hope this helps!!
