I'm confused by this problem and don't know where to go from here, any would be appreciated.

integral from 0 to 1 of f(t) dt = 28, find integral from -1.5 to -1 of f(3 + 2t) dt.

i set u = 3 + 2t and therefore du = 2 dt, then ended up with 1/2 * the integral from -1.5 to -1 of f(u) du.

Let hh represent the number of hummingbirds and ss represent the number of sunbirds that must pollinate the colony so it can survive until next year. 6h+4s > 746h+4s> 74 this year, 88 hummingbirds pollinated the colony. what is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.

The volume of a box varies directly with its length if a box in the group has a length of 30inches and k=24 what is its volume
