Answer:


Step-by-step explanation:
We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.
First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the hypotenuse is:

So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.
Then it follows that:

And that:

9514 1404 393
Answer:
y = 697
Step-by-step explanation:
Put the value of x into the equation and do the arithmetic.
y = 3·225 +22 = 675 +22
y = 697
Answer:
Presuming the 4.2 cm is the radius the diameter would be 8.4 cm
Step-by-step explanation:
Radius is half the diameter
So it would be 4.2 X 2 for the diameter
Correct me if I'm wrong
Let n be the original price. Then 15.20=(1-0.24)n
0.76n=15.20
n=$20.00 as the original price of the photograph
