Answer
This is how too apply it in trig when trying to find a side with only the degree and the side.
Answer:
3
Step-by-step explanation:
The constant of proportionality (or the slope) is 3. Observe that if x increases by 2 (from 1 to 3), y increases by 6 from 3 to 9, so that m = rise/run = 6/2, or 3.
Answer:
f(x) + g(x) = 2x² - 5x - 8 ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- We can add to functions by adding the like terms in them
∵ f(x) = 2x² + 3x - 4
- f(x) is a quadratic function because the greatest power of x is 2
∵ g(x) = -8x - 4
- g(x) is a linear function because the greatest power of x is 1
∵ f(x) + g(x) means (f + g)(x)
∴ f(x) + g(x) = (2x² + 3x - 4) + (-8x - 4)
- Add the like terms
∵ 3x + -8x = -5x
∵ -4 + -4 = -8
∴ f(x) + g(x) = 2x² + -5x + -8
- Remember (+)(-) = (-)
∴ f(x) + g(x) = 2x² - 5x - 8
* f(x) + g(x) = 2x² - 5x - 8
Answer:
8 pi m
Step-by-step explanation:
area of a circle is 2r pi
2(4) pi = 8 pi
I think this is false. You should probably try reading the question first, otherwise you can't try to figure out what the question is asking you to solve in the first place!
