Suppose you start with a full tank of gas (20 gallons) in your truck. After driving 6 hours, you now have 6 gallons left.
If x is the number of hours you have been driving, then y is the number of gallons left in the tank.
At what rate is the gas left in the tank changing? State your answer as a reduced fraction.
gallons per hour
Find an equation of a line in the form y = mx + b that describes the amount of gas in your tank.
y =

step-by-step explanation:

107 units

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

it is only things thain can be deafeated
