T(t)T, models the daily high temperature (in Celsius) in Santiago, Chile, t days after the hottest day of the year. Here, t is entered in radians.

T(t)=7.5cos(2π/365t)+21.5

What is the second time after the hottest day of the year that the daily high temperature is 20 degrees celsius?

Round your final answer to the nearest whole day.

He concluded that a heavier object dropped from the same height as a lighter object will land

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

Simplify. (-2)^-3 a. -8 b. -1/8 c. 1/8 d. 8
