Answer:
C 13.3 units
Step-by-step explanation:
The Pythagorean theorem is used to find the distance between two points. On a graph like this, you can count the number of squares between points horizontally and vertically, so can fill in the calculation for the hypotenuse directly from the graph.
... hypotenuse length = √((horizontal distance)² +(vertical distance)²)
... JK = √(2²+2²) = √8 ≈ 2.83
... KL = √(2²+5²) = √29 ≈ 5.39
... LM = √(2²+2²) = √8 = 2.83
... MJ = √(2²+1²) = √5 ≈ 2.23
The perimeter is the sum of these distances around the figure:
... perimeter = JK +KL +LM +MJ
... perimeter = 2.83 +5.39 +2.83 +2.23 = 13.3
468/18 = 26
Therefore they need at least 26 boxes to hold all the golf balls.
Hope this helps :)

Step-by-step explanation:
Answer:
f(g(x)) = 15x³ - 5
Step-by-step explanation:
how confusingly described.
let me try and summarize what I understood :
f(x) = 3x² - 5
money earned when baking x cookies.
g(x) = sqrt(5x³)
the amount of cookies baked in x hours.
f(g(x)) now calculates how much money she earns when baking for x hours.
it is basically very simple : instead of f(x) we have f(g(x)), so g(x) is used as argument/variable in f instead of just plain x.
therefore,
f(g(x)) = 3×(sqrt(5x³))² - 5
with x now representing the baking hours, but f(...) calculating the overall money earned, by implicitly (!) calculating the amount of cookies baked in that time and taking that result automatically to calculate the earned money.
let's simplify this a little bit more.
f(g(x)) = 3×(sqrt(5x³))² - 5 = 3×(5x³) - 5 = 15x³ - 5
