Answer:
Step-by-step explanation:
I am assuming that you are asking what is [x] - 5 if f(86).
When you have this kind of question, what you do is to substitute the variable inside the parenthesis, so like what is says, f(x). If the question replaces the variable x with 86, that means you input the number into the equation.
So [x] - 5, if f(86).
Substitute:
86 - 5
The answer is B. because if you take 4.20 and divide it by 3.5 you get 1.20
Answer:
The answer is B
Step-by-step explanation:
Its B because Y= x+3 means that the Y is 3 more then the X value so B is correct
Basically you have to use trigonometry to solve this. You will be using a sine ratio. Type sin-1(36/43). Use the 2nd button to do this. Your answer should be 56.84659158 but round to 57.
