Janye stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which equation relates the to
AlexFokin [52]

Answer: y = x + 4

Step-by-step explanation:

Since the total number of gasoline is given to be "y", with an initial quantity of filled gasoline to be "4" and the quantity of unfilled gasoline to be "x".

Therefore, the summation of the filled and unfilled quantity of gasoline will be "x + 4" which is equal to the total capacity of the tank "y".

What is the domain and range for the following function and its inverse?
Basile [38]

Answer:

"f(x)  

domain: all real numbers, range: all real numbers  

f–1(x)  

domain: all real numbers, range: all real numbers"

Step-by-step explanation:

We can use the fact that the domain of a function and the range of its inverse are equal.

Also, the range of the function and the domain of its inverse are equal as well.

<em>Looking at the function f(x/ = -x + 5, we see that this is a line with a negative slope of 1 and a y-intercept of +5. </em>

As we know from the graph of lines, there is no restricting values in x and y. So for the original function,  domain is the set of all real numbers and the range is the set of all real numbers.

For the inverse, the range is set of all real numbers and domain is also the set of all real numbers.

First answer choice is right.

Answer:

  12.0 cm

Step-by-step explanation:

Use the formula for the volume of a cylinder. Fill in the given values and solve for the height.

  V = πr^2h

  1846 cm^3 = π(7 cm)^2·h

  h = 1846/(49π) cm ≈ 12.0 cm . . . . . . divide by the coefficient of h

The height of the can is about 12.0 cm.
