37.1
35 * .06 = 2.1
35 + 2.1 = 37.1
Answer:
radius = 13
Step-by-step explanation:
Look at the attached picture below. We can calculate radius with the help of the Pythagorean theorem. But first we have to find out the values of the two legs.
First let's find the shorter leg.
<u>Equidistant Chords Theorem</u>
Two chords are congruent if they are equidistant from the center.
Chords in the picture are congruent and that means that the distance from the center to each of them is the same!
Let's calculate the distance. But to get the distance we have to find x first.
Since the distances are the same:

Therefore:

Let's focus on the longer leg. Since part of the radius is perpendicular to the chord, it actually bisects the chord! That means that the long leg is going to be a half of the length of the chord.
Therefore:

All that is left is the Pythagorean Theorem in the right triangle.
<u>Pythagorean Theorem</u>

Hypotenuse in our case is the radius.

Answer:
(5,-3) is a solution of -x-y=-2
Step-by-step explanation:
You just plug in the numbers in the equation
x=5 y=-3
-5(5)+2(-3)=-25-6 which doesn't equal -21
-5-(-3)=-5+3=-2
Hope this helps!! I just distributed when needed and solved for the unknown variable
It actualy gives you the minimum of the function
it helps you because fonding the minimum y will give you the range
