Given the following : f(x)=3x^ 1 2 +7x^ - 1 4 +8x^ -4 ;g(x)=- 7 4 x^ 1 2 +12x^ - 1 4 -1 ; and h(x) = 8x ^ 3 + 12x ^ (- 1/2) + 8x ^ (1/4) - 14x ^ - 4

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

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).
