The graph shows the volume of water in a sink x minutes after the faucet is turned on. Graph of a diagonal line on a coordinate plane going up and to the right with Time (min) on x-axis and Volume (gal) on y-axis. When min is 0, gal is 0. When min is 8, gal is 4

Part A
What is the slope of the line?

plz yuo

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
