Answer:
![y = \frac{19}{8}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B19%7D%7B8%7Dx)
Step-by-step explanation:
Given
The attached graph
Required
Equations with higher unit rate
First, calculate the unit rate of the graph
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Where:
![(x_1.y_1) = (0,0)](https://tex.z-dn.net/?f=%28x_1.y_1%29%20%3D%20%280%2C0%29)
![(x_2.y_2) = (7,15)](https://tex.z-dn.net/?f=%28x_2.y_2%29%20%3D%20%287%2C15%29)
So:
![m = \frac{15 - 0}{7 - 0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B15%20-%200%7D%7B7%20-%200%7D)
![m = \frac{15}{7}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B15%7D%7B7%7D)
![m = 2.143](https://tex.z-dn.net/?f=m%20%3D%202.143)
For the given options.
The unit rate is the coefficient of x
So: ![y = \frac{19}{8}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B19%7D%7B8%7Dx)
Going by the above definition of unit rate.
![m = \frac{19}{8}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B19%7D%7B8%7D)
![m = 2.375](https://tex.z-dn.net/?f=m%20%3D%202.375)
![y = \frac{27}{13}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B27%7D%7B13%7Dx)
![m = \frac{27}{13}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B27%7D%7B13%7D)
![m = 2.077](https://tex.z-dn.net/?f=m%20%3D%202.077)
![y = \frac{21}{9}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B21%7D%7B9%7Dx)
![m = \frac{21}{9}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B21%7D%7B9%7D)
![m = 2.333](https://tex.z-dn.net/?f=m%20%3D%202.333)
![y= \frac{11}{5}x](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B11%7D%7B5%7Dx)
![m= \frac{11}{5}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B11%7D%7B5%7D)
![m= 2.20](https://tex.z-dn.net/?f=m%3D%202.20)
![y = \frac{15}{7}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B15%7D%7B7%7Dx)
![m = \frac{15}{7}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B15%7D%7B7%7D)
![m = 2.143](https://tex.z-dn.net/?f=m%20%3D%202.143)
![y = \frac{31}{15}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B31%7D%7B15%7Dx)
![m = \frac{31}{15}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B31%7D%7B15%7D)
![y = 2.067](https://tex.z-dn.net/?f=y%20%3D%202.067)
![y=\frac{13}{6}x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B13%7D%7B6%7Dx)
![m=\frac{13}{6}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B13%7D%7B6%7D)
![m=2.167](https://tex.z-dn.net/?f=m%3D2.167)
The unit rates grater than the graph's from small to large are:
![y = \frac{19}{8}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B19%7D%7B8%7Dx)
![m = \frac{19}{8}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B19%7D%7B8%7D)
2 solutions. This is because the parabola will cross the x axis twice. We know this because -5 means the vertex will be 5 units below the x axis. and the parabola opens upwards because the first coefficient is positive. Hope this helped :)
<u>Answer:</u>
Yes,two planes descending at the same angle
<u>Explanation:</u>
Given the angle of deviation as seen by the pilot is equal to 15 degrees,
i.e the angle made by the line of sight with the ground is 15 degrees also the angle of elevation from a person at ground to the other plane is given to be equal to 15 degrees
which means the angle made by line of sight to plane and ground is equal to 15 degrees hence both of these situations refer to the same angle at a point and hence both planes are descending at the same angle.
In order to calculate the value of the hypotenuse we use knowledge on trigonometric functions. For this case, we can use the sine function. We do as follows:
sin 55 = 16 / c
c = 19.5330
Therefore, the correct answer is option B.
