8. in 1787 the french scientist jacques charles observed that when he plotted the graph of
volume of a fixed amount of air versus the temperature of the air, the points were linear.
suppose that at 27°c a certain amount of air occupies a volume of 500 cm'. when it is warmed
to 90°c it occupies 605 cm”.
a. write the linear equation expressing volume in terms of temperature.
b. predict the volume at 60°c.
c. if the volume is 700 cm? , what is the temperature?

the infinity sign

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
