Answer:
1080
___ rode a plane for 5^2 miles on a flight to ___. She then took a flight to ___ which was 5^4 miles. How much further did she fly on the second flight?
you can decide where she went and what her name was.
Step-by-step explanation:
6^3 = 213
6^4 = 1296
1296 - 216 = 1080
Given:
In triangle ABC, a = 6, c = 4, and B = 75°.
To find:
The measure of b.
Solution:
According to the Law of Cosine:
![b^2=a^2+c^2-2ac\cos B](https://tex.z-dn.net/?f=b%5E2%3Da%5E2%2Bc%5E2-2ac%5Ccos%20B)
Substituting the given values in the above formula, we get
![b^2=(6)^2+(4)^2-2(6)(4)\cos (75^\circ)](https://tex.z-dn.net/?f=b%5E2%3D%286%29%5E2%2B%284%29%5E2-2%286%29%284%29%5Ccos%20%2875%5E%5Ccirc%29)
![b^2=36+16-48(0.2588)](https://tex.z-dn.net/?f=b%5E2%3D36%2B16-48%280.2588%29)
![b^2=52-12.4224](https://tex.z-dn.net/?f=b%5E2%3D52-12.4224)
![b^2=39.5776](https://tex.z-dn.net/?f=b%5E2%3D39.5776)
Taking square root on both sides, we get
![b=\sqrt{39.5776}](https://tex.z-dn.net/?f=b%3D%5Csqrt%7B39.5776%7D)
![b=6.291073](https://tex.z-dn.net/?f=b%3D6.291073)
![b\approx 6.29](https://tex.z-dn.net/?f=b%5Capprox%206.29)
The measure of side b is 6.29 units.
Therefore, the correct option is B.
Answer:
x + y
Step-by-step explanation:
An expression for the average of x,2x and 3y
average = (x+2x+3y)/3
= (3x+3y)/3
= 3(x+y)/3
= x + y
