Answer:
D
Step-by-step explanation:
Cos(D) = adjacent / hypotenuse
The adjacent side is the one making up angle D
adjacent side = f
hypotenuse = e
Cos(D) = f/e
D = cos-1(f/e)
The answer would be 20
A squares sides are equal and there are 4 of them so you take 80 (the total perimeter) and divide that number by 4 (number of sides) and you get 20
Answer: x = 4
Step-by-step explanation:
To solve this problem, make use of the fact that you may add anything to an equation, as long as you do it to both sides.
Simply add 4x to both sides to get:
13 = 1 + 3x
Then simply add -1 to both sides to get:
12 = 3x
Then, divide both sides by 3 to get:
4 = x
Hope it helps :) and let me know if you want me to elaborate.
Answer:
Pease check my assumptions.
Step-by-step explanation:
I will assume that f(x)=x2 is actually f(x) = x^2.
Same for g(x)=(12x)^2 [Is it g(x)=12x^2 ???]
See the attached image.
Note that (12x)^2 results in a narrower, steeper graph. That's because (12x)^2 can be rewritten as 144x^2, so every value is multiplied by 144, compared to just x^2.
