Step-by-step explanation:
5x4-3x2+2x-4/x-3
=2x+5×4-3×2-4/x-3
=2x+32/x-3

Answer:
To use division to find the decimal equivalent of a rational number, divide the top number by the bottom number. You will get a decimal number.
We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write
... d = 75-12sin(π·t/12)
