Answer:
19.08
Step-by-step explanation:
c² = a² + b² - 2ab×cos(C)
a=10
b=22
C=60
cos(60) = 0.5
c² = 10² + 22² - 2×10×22×cos(60) =
= 100 + 484 - 20×22×0.5 = 584 - 20×11 = 584 - 220 =
= 364
c = sqrt(364) ≈ 19.08
Answer:
Option A is correct.
4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5
Step-by-step explanation:
Given the expression: 
If n = -5
then, by substituting in given expression we get;

Option A:
4n + 8
Substitute the value of n = -5 we have;

Option B:
2n + 2
then;
2(-5) + 2 = -10 + 2 = -8
Option C :

then;

Option D:
n + 8
then;
-5 + 8 = 3
Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5

Answer:
92
Step-by-step explanation:
83*4 = 332
And 80*3 = 240
332-240 = 92
So you would need 92
ANSWER

EXPLANATION
From the graph, the coordinates of Y are:

We want to find the image of this point after a dilation by a scale factor of -½ about the origin.
The rule for the dilation is :

To find the coordinates of Y', we plug the coordinates of Y.


The first choice is correct.
