3×50=150
Answer:
Step-by-step explanation:
sin x=a+b
cos x=a-b
sin²x+cos²x=(a+b)²+(a-b)²=2a²+2b²
or 2a²+2b²=1
a²+b²=1/2 which is constant for all values of x
(ii)
![\frac{\sin x}{\cos x}=\frac{a+b}{a-b}\\\tan x=\frac{a+b}{a-b}=2\\a+b=2a-2b\\b+2b=2a-a\\or a=3b](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%20x%7D%7B%5Ccos%20x%7D%3D%5Cfrac%7Ba%2Bb%7D%7Ba-b%7D%5C%5C%5Ctan%20x%3D%5Cfrac%7Ba%2Bb%7D%7Ba-b%7D%3D2%5C%5Ca%2Bb%3D2a-2b%5C%5Cb%2B2b%3D2a-a%5C%5Cor%20a%3D3b)
Based on the rate that Leon's car uses gas, the time that Leon will stop to get gas is 3:36 pm.
<h3>When will Leon stop to get gas?</h3>
Leon will stop to get gas when the tank is 1/4 full which is:
= 1/4 x 12
= 3 gallons
The rate at which the car uses gas is:
= Gallons used / Time traveled
= 5 / 2
= 2.5 gallons per hour
The number of hours till he has to stop is:
= (12 gallons - 3 gallons) / 2.5
= 3.6 hours
The time that Leon will stop is:
= 12pm + 3.6 hours
= 12 pm + 3 hours 36 minutes
= 1536 hours
= 3:36 pm
