Right-angled triangle. Let x be the required angle. Tan x = 8/6. x= 53.1°
Answer:

Step-by-step explanation:
Let
x ----> the number of hours
y ---> the total cost of renting a jet ski in dollars
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to

we have the ordered pair (3,265)
substitute in the linear equation

solve for b

substitute

Answer:
-1/root2
Step-by-step explanation:
7pi/4 radians is the same as -pi/4 radians
sin(-pi/4) is -sin(pi/4) = -1/root2
It would be about 4/10 of a gallon
