Answer:
approx 15.5 hours
Step-by-step explanation:
475/30 = 15.83 miles per hour
245 = 15.83·t
t = 245/15.83
t = 15.5 hours
Let us draw a triangle ABC with A=15° ,B=113° and b=7.
Please see the attached image.
We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have
![A+B+C=180\\ \\ 15+113+C= 180\\ \\ C=62^{\circ}](https://tex.z-dn.net/?f=A%2BB%2BC%3D180%5C%5C%0A%5C%5C%0A15%2B113%2BC%3D%20180%5C%5C%0A%5C%5C%0AC%3D62%5E%7B%5Ccirc%7D)
Apply Sine rule in the triangle ABC, we get
![\frac{a}{\sin 15}= \frac{7}{\sin 113}\\ \\ a=\frac{7 \sin 15}{\sin 113}\\ \\ a=1.97\\ \\ \text{Again apply sine rule, we get}\\ \\ \frac{c}{\sin 62}= \frac{7}{\sin 113}\\ \\ c=\frac{7 \sin 62}{\sin 113}\\ \\ c=6.71](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B%5Csin%2015%7D%3D%20%5Cfrac%7B7%7D%7B%5Csin%20113%7D%5C%5C%0A%5C%5C%0Aa%3D%5Cfrac%7B7%20%5Csin%2015%7D%7B%5Csin%20113%7D%5C%5C%0A%5C%5C%0Aa%3D1.97%5C%5C%0A%5C%5C%0A%5Ctext%7BAgain%20apply%20sine%20rule%2C%20we%20get%7D%5C%5C%0A%5C%5C%0A%5Cfrac%7Bc%7D%7B%5Csin%2062%7D%3D%20%5Cfrac%7B7%7D%7B%5Csin%20113%7D%5C%5C%0A%5C%5C%0Ac%3D%5Cfrac%7B7%20%5Csin%2062%7D%7B%5Csin%20113%7D%5C%5C%0A%5C%5C%0Ac%3D6.71)
Therefore, we have
![a=1.97\\ c=6.71\\ C=62^{\circ}](https://tex.z-dn.net/?f=a%3D1.97%5C%5C%0Ac%3D6.71%5C%5C%0AC%3D62%5E%7B%5Ccirc%7D)
Answer: Function g reflected function f across the x-axis.
For function g, as x approaches negative infinity, g(x) approaches negative infinity.
Function f is symmetrical about the point (4,6).
STEP 1: ADD ALL OF THE NUMBERS TOGETHER.
STEP 2: DIVIDE THE TOTAL BY THE AMOUNT OF NUMBERS SHOWN
