= C(12,2)/C(52,2) = 66/1326 = 11/221
Answer:
{-9,1,11}
Step-by-step explanation:
Just place the domain values to your x value in the function.
Answer:
x = 65.03°
Step-by-step explanation:
To solve for x, we have to apply trigonometric ratio.
Recall: SOH CAH TOA
From the diagram, we know the following:
Reference angle = x
Hypotenuse = 45
Adjacent = 19
Since we know the Hyp and Adj, we would apply CAH, which is:
Cos x = Adj/Hyp
Plug in the values


x = 65.0250346°
x = 65.03° (nearest hundredth)
Your answer for -16 divided by 2 will be -8, because half of 16 is 8, but you are just in the negative numbers:)! So your answer is -8
Answer:
15
Step-by-step explanation:
