the revenue from selling x shirts is r(x) = 15x.

the cost of buying x shirts is c(x) = 7x + 20.

the profit from selling x shirts is p(x) = r(x) – c(x).

what is p(x)?

a. p(x) = 22x – 20
b. p(x) = 22x + 20
c. p(x) = 8x – 20
d. p(x) = 8x + 20

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
