Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²
so given
center at (9,-8)
(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²
input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r
well, the equation is
(x-9)²+(y+8)²=1000
Answer:
13 egrets
Step-by-step explanation:
According to the Question,
Given That, Molly is birdwatching at the coast. She has seen 2 egrets and 4 other birds. Considering this data.
Therefore, The next 39 birds Molly sees would you expect to be egrets is
⇒ (39/6)×2 = 13 egrets.
"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.
<u>Option: C</u>
<u>Explanation:</u>
When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.
The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.
In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:
120 + 120 + 120 = 360°.
Answer:
x ≤15
Step-by-step explanation:
2x ≤30
Divide each side by 2
2x/2 ≤30/2
x ≤15
First quartile would 65 because....
well first order the numbers around : 55, 65,72,73,88,90,100
the median is 73, the first quartile in the medians of the numbers lower than the whole sets. That means in the subset of the numbers the median would be: 55, 65, 72.
crossing out 55 and 72 you have 65.
