The graph of this sinasoid wave is B) f(x) = 3cos(x) + 3
We can tell this for two reasons. Firstly, the multiplier in the beginning is always equal to half of the height of the graph. Since the graph goes as high at 6 and as low as 0, we know the overall height is 6. Half of that is 3. This means that we have a 3 for the multiplier.
Next, we can decide between sin and cos by determining that it starts up and ends down. Sin starts moving up at the beginning and cos moves up at the beginning. Therefore, it must be the cos.
Answer:
2:1
Step-by-step explanation:
w:x = 4:6
y:x = 1:3
if w = 4 and x = 6, y = 1/3x = 2
If w = 4 and y = 2, then the ratio is;
w:y = 2:1
For this, we will be using the pythagorean theorem, which is 
. Since we have the hypotenuse and one of the legs, we can solve for the other leg. Our equation will look like this: 
Firstly, solve the exponents: 
Next, subtract 3600 on both sides: 
Next, square root both sides, and your answer will be x = 80 units
Answer:118
Step-by-step explanation:
It has to equal 180 degrees in total so 48+14=62
180-62=118
So the answer is 118
