Answer:
x=2.25hrs
Step-by-step explanation:
1/9 =1/4hr
9/9=x
(9/9)/(1/9)=1/4.xhr
1/9=1/4.xhr
cross multiplying
4x=9
x=9/4
x=2.25hrs
Answer:
There is no relationship, except they do intersect at the point (1, -1). Hope this helps :)

Option C:
x = 90°
Solution:
Given equation:
<u>To find the degree:</u>
Subtract 1 + cos²x from both sides.
Using the trigonometric identity:
Let sin x = u
Factor the quadratic equation.
u + 2 = 0, u – 1 = 0
u = –2, u = 1
That is sin x = –2, sin x = 1
sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.
sin x = 1
The value of sin is 1 for 90°.
x = 90°.
Option C is the correct answer.
First let’s establish a few things, The first car can travel 300 miles with 20 gallons of gas, if 14 gallons of gas costs 49.49 then for ever gallon of gas Sam is paying 3 dollars and 53.5 cents. That means for 20 gallons, Sam will need around 71$ for the entire trip if he uses the first car.
