Assuming that this is a right triangle, then (50 in)^2 = b^2 + (14 in)^2, according to the Pythagorean Theorem.
Then 196 in^2 + b^2 = 2500 in^2. Solving for b^2:
b^2 = (2500-196) in^2, and so b = +48 inches (answer)
X less than or equal to 2
From c=b-5
Independent variable is b, the number of cookies in the jar before your visit
Dependent variable is c, the number of cookies remaining in jar
Any questions please just ask. Thanks!
