Answer:
31 miles
Step-by-step explanation:
The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. The top of the stratosphere occurs at an altitude of 50 km (31 miles).

The Cosine Law:
c² = a² + b² - 2 a b cos C
14² = 28² + b² - 56 · b · √3/2
196 = 784 + b² - 28√3 b
b² - 28√3 b + 588 = 0
b 1/2 = (28√3 +/- √(2352 - 2352 )) / 2 = 28√3 / 2 = 14√3
Answer:
The given measurements determine one triangle.
Answer:
f(2)=4
Step-by-step explanation:
![\\ \rm\longmapsto f(x)=x^2,x>1](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5Clongmapsto%20f%28x%29%3Dx%5E2%2Cx%3E1)
![\\ \rm\longmapsto f(2)=2^2](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5Clongmapsto%20f%282%29%3D2%5E2)
![\\ \rm\longmapsto f(2)=4](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5Clongmapsto%20f%282%29%3D4)
For question 4: you have to do (y2 - y1) divided by (x2 - x1) to get the rise over run...
5-2
——. = 3/4
11 - 7
For question 5: input the values of x,y and the gradient into the equation of a line.....
y = mx+ c
-8 = 3(-2) + c
-8 = -6 + c
-2 = c
therefore:
y = 3x - 2
