Using the given equation, replace s with 4 and solve for t:

t = 0.0119s^2 - 0.38s -0.0003

t = 0.0119(4)^2 - 0.38(4) - 0.0003

t = 0.0119(16) - 1.52 - 0.0003

t = 0.1904 - 1.52 - 0.0003

t = -1.3299

Rounded to the nearest hundredth t = -1.33

This means the runner would finish 1.33 seconds faster. ( Lower time)

Answer:

1/9 = 1/45*5

Step-by-step explanation:

When you divide by something, you multiply by its reciprocal so...

1/9 * 1/5=1/45

Now we need to know what 1/9 equals so we can divide both sides by 1/5

1/9=1/45 divided by 1/5

Again you need to multiply by its reciprocal

1/9 = 1/45*5
