Answer:
Independent: miles travelled
Dependent: gallons of gas
Gas remaining after 68 miles: 7.2 gallons
Step-by-step explanation:
Looking at the table, it appears that after every 17 miles of driving, 1 gallon of gas is used.
- 68 miles would be the next 17 miles after driving 51 miles
- this means another gallon of gas would be used, so 8.2 - 1 = 7.2 gallons left
The <u>dependent variable</u> is the variable that depends on that of another
- In this case, the dependent variable is the gallons of gas, because in order for the car to drive, it needs gas
The <u>independent variable</u> is the variable that does not depend on that of another
- In this case, the independent variable is the miles travelled
Step-by-step explanation:
we use the law of sine :
sin(A)/a = sin(B)/b = sin(C)/c
with the related angles being opposite of the lines.
so, we have
sin(A)/1 = sin(A) = sin(90)/ sqrt(10) = 1/ sqrt(10) =
= 0.316227766...
cos²(A) + sin²(A) = 1
cos(A) = sqrt(1 - sin²(A)) = sqrt(1 - 0.1)) = sqrt(0.9) =
= 0.948683298...
tan(A) = sin(A)/cos(A) = 0.333333333...
cot(A) = 1/tan(A) = 3
sec(A) = 1/cos(A) = 1.054092553...
csc(A) = 1/sin(A) = 3.16227766...
