I'm pretty sure it's 50°f because the original temperature is 37°f and after 8 minutes it was 42°f and 42 minus 37 is 5, 8 divided by 5 is 1.6 and then multiply that by 5 is 8 and 42 + 8=50°F

Find the volume of the solid of revolution formed by rotating the bounded region about the x-axis.

lana66690 [7]

Answer:

$40.5 \pi$ cubic units

Step-by-step explanation:

Given is a function exponential as

$f(x) =\sqrt{ (x-4)}$

The region bounded by the above curve, y =0 , x =13 is rotated about x axis.

the intersection point is at x=4

The limits for x are 4 and 13

The volume when rotated through x axis is found by

$\pi\int\limits^b_a {f(x)^2} \, dx$

Here a = 4 and b =13

volume = $\pi\int\limits^13_(4) x-4} \, dx$

= $\pi (\frac{x^2 }{2}-4x )\\= \frac{\pi}{2} (153-72)\\= 40.5 \pi$ .cubic units

The graph of a linear function passes

dlinn [17]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.
