Devora tested two engines. As each engine's rotation got faster, its temperature increased at a constant rate.

The first engine's temperature (in degrees Celsius) as a function of its rotation speed (in cycles per second) is given by the following table of values:

The Table is for the first engine below
For the second engine, the graph is below

Answer:

The answer to number 1 is B.

The answer to number 2 is B.

Step-by-step explanation:

I did the lesson on khan academy.

The engine whose temperature increased more for each increase of 1 cycles per second is; The second Engine

What is the Increase in Temperature?

1) We want to find the engine whose temperature increased more for each increase of 1 cycles per second.

Now, for the first engine, the increase in temperature is required when there is an increase of 1 cycle of rotation per second we need to find the slope. Thus,

Slope = Δy/Δx = (28.8 - 26.4)/(11 - 8)

Increase in temperature per 1 cycle of rotation increase = 0.8

For the second engine, the slope is;

Slope = (28 - 22)/(5 - 0)

Slope = 1.2

Thus, the second engine has temperature that increased more for each increase of 1 cycles per second.

2) Since the rate of increase in Engine 2 is higher, it menas it will be hotter at 20 cycles rotation per second
