First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
I can't see photo so pls put one
Answer:
1.65%
Step-by-step explanation:
We will assume the percentage was the same over the 5 years. The number of passengers using a railway is expressed by the formula
Where
P(t) is the number of passengers after 5 years
P(t) = 174,989
P₀ is the number of the passengers at the beginning of the period
P₀ = 190,205
r is the rate in percentage r = ?
t is time duration t = 5 years
Substituting these given values into the formula,
![1 - r = \sqrt[5]{ \frac {174,989}{190,205}}](https://tex.z-dn.net/?f=1%20-%20r%20%3D%20%5Csqrt%5B5%5D%7B%20%5Cfrac%20%7B174%2C989%7D%7B190%2C205%7D%7D)
![1 - r = \sqrt[5]{0.920}](https://tex.z-dn.net/?f=1%20-%20r%20%3D%20%5Csqrt%5B5%5D%7B0.920%7D)
r = 1.65%
The annual percentage decrease over the period of 5 years is 1.65%
