(3.5, 1.5) are the coordinates
hope this helps
Answer:
r = 18.8
Step-by-step explanation:
We use the circle sector area formula and solve for the radius.
I attached the work to your problem. See the attached file.
For this case we have to define trigonometric relations of rectangular triangles that:
- The cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle.
- The sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle.
Then, according to the figure we have:
![Sin (G) = \frac {15} {17}\\Cos (G) = \frac {8} {17}](https://tex.z-dn.net/?f=Sin%20%28G%29%20%3D%20%5Cfrac%20%7B15%7D%20%7B17%7D%5C%5CCos%20%28G%29%20%3D%20%5Cfrac%20%7B8%7D%20%7B17%7D)
Answer:
![Sin (G) = \frac {15} {17}](https://tex.z-dn.net/?f=Sin%20%28G%29%20%3D%20%5Cfrac%20%7B15%7D%20%7B17%7D)
Option D
You'll reach destination in 1.6 days or rounded to 2 days.
->calculate how much did you pass already 1250×5/7=892 miles traveled (rounded)
->then calculate how much miles you have to go
1250-892=358 miles left to travel
->then calculate speed at which you travel
892/4(how much days you traveled already)=223miles per day
->then just divide miles left with speed
358/223=1.6 or 2 days left to reaching destination.
The equivalent ration is B
