Answer:
For this case we can model the problem as a rectangle triangle.
We know:
Length of the hypotenuse
Angle between the base of the triangle and the hypotenuse.
We want to know:
Length of the base.
For this we use the following trigonometric relationship:
cos (15) = \frac{x}{500}cos(15)=500x
Clearing x we have:
x = 500 * cos (15) x = 482.96x=500∗cos(15)x=482.96
Rounding to the nearest tenth of a meter:
x = 483.0 mx=483.0m
Answer:
The horizontal distance she has covered is:
x = 483.0 mx=483.0m
Answer k=16
A recipe says to use 3 cups of flour to make 48 cookies.
the number of cookies made, y, to the number of cups of flour used,x .
Than
y = kx
Where k is the constant of proportionality.
48 = 3k
k = 16
Therefore the constant of proportionality is 16.
Lets solve f(5). First, replace all "n"s in the equation with 5s. F(5+1)=F(5)-2. This means that F(6)=F(5)-2, F(5)=F(4)-2, F(4)=F(3)-2, F(3)=F(2)-2, and F(2)=F(1)-2. Because we know F(1)=18, F(2)=16, F(3)=14, F(4)=12, and F(5)=10.

Answer:
$85.50
Step-by-step explanation:
57 * .5 = 28.5
28.5 + 57 = 85.5
therefore, the answer would be $85.50
