The weight of the books carried in a backpack depends on the number of books in the backpack. susan’s books weigh from 1 pound to 3.5 pounds each and she carried at most 4 books. find a reasonable domain and range for the situation. (, a little here? )

4 - 14 lbs

Step-by-step explanation:

Ok, so the most she can carry is 4 books. and they weigh 1 - 3.5 lbs. so you take 1 times 4. and thats well 4. then you do 3.5 times 4. thats 14 so your range would be 4 -14 lbs

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
