Answer:
Option A)
Step-by-step explanation:
We are given the following in the question:
V varies jointly as h and the fifth power of r.
Combing the two equations, we get,
Now, removing the sign of proportionality and adding the constant of proportionality, we get,
where k is the constant of proportionality.
Thus, the correct answer is
Option A)
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
If we have:
Thus, the equation is of the form:
We substitute the point:
Finally, the equation is:
Answer:
Change 1 hour 15 minutes = 1.25 hour because 15 ÷ 60 = 0.25 so we add 0.25 hour and change 2 3/4 to 2.75
Equation:
Multiply 2.75 × 1 = 2.75 ÷ 1.25 =
2.2 miles
I'm pretty sure this is correct
Answer:
9.8
Step-by-step explanation:
We have the following formula:
We have that:
So
The total distance traveled in kilometers is 9.8
The answer is -
2x^2 + 2x + 7
