The simplified polynomial that represents how many more economy cars are rented in w weeks than full-size cars is 53 - w.
<h3>Linear equation:</h3>
Linear equation is an equation in which the highest power of the variable is equals to one.
Therefore, the number of economy-size cars rented in w weeks is represented as follows:
The number of full-size cars rented in w weeks is represented as follows:
where
w = number of weeks
A simplified polynomial that represents how many more economy cars are rented in w weeks than full-size cars is as follows:
- 152 + 3w - (99 + 2w)
- 152 + 3w - 99 - 2w
- 53 - w

Answer:
1/sqrt10
Step-by-step explanation:
1) Find out cosA using formula (cosA)^2+(sinA)^2=1
The module of cosA= sqrt (1- (-3/5)^2)= sqrt 16/25=4/5
So cosA=-4/5 or cosA=4/5.
Due to the condition 270degrees< A<360 degrees, 0<cosA<1 that's why cosA=4/5.
2) Find sinA/2 using a formula cosA= 1-2sinA/2*sinA/2 where cosA=4/5.
(sinA/2)^2= 0.1
sinA= sqrt 0.1= 1/ sqrt10 or sinA= - sqrt 0.1= -1/sqrt10
But 270°< A< 360°, then 270/2°<A/2<360/2°
135°<A/2<180°, so sinA/2 must be positive and the only correct answer is
sin A/2= 1/sqrt10
