The marketing research department of a computer company used a large city to test market the firm's new laptop. the department found the relationship between price p (dollars per unit) and the demand x (units per week) was given approximately by the following equation. pequals1836 minus 0.17 x squared 0less thanxless than75 so, weekly revenue can be approximated by the following equation. upper r (x )equalsxpequals1836 x minus 0.17 x cubed 0less thanxless than75 use this information to answer parts (a) and (b).

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

f(x) = y

f(-3) = -5
