15x+10z is equivalent to 5(3x+2z)
Answer:
What do you mean a radius equal to 12 feet? What is your question?
Step-by-step explanation:
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)
This question is worded weirdly, but it means:
8 / (5/2)
= 8 * (2/5)
= 16/5
