Answer:
You have to put energy into a molecule to break its chemical bonds. The amount needed is called the bond energy. After all, molecules don't spontaneously break

Answer:
1884.785
Step-by-step explanation:
24.5 × 24.5=600.25
600.25 × 3.14=1884.785
Answer:
The constant of variation is 5.
Step-by-step explanation:
In direct variation, as y varies directly with x, the standard equation is
y = kx,
where k is the constant of variation.
In your case, we use R and S. R varies directly with S, so we have
R = kS
We know that when S = 16, R is 80, so we plug in those values and solve for k, the constant of variation.
R = kS
80 = k(16)
k = 80/16
k = 5
The percent of variation is 85.1%. If you enter the numbers into a calculator and store the regression equation, it will be the r^2 value when calculated.
