Does a negative exponent result in a negative answer

madam [21]

No! Remember, you see a negative exponent, that just means the reciprocal of the positive exponent. So 1 over negative 2 to the third power, to the positive third power. And this is equal to 1 over negative 2 times negative 2 times negative 2. ... So this is equal to negative 1/8.

Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 fee

Trava [24]

Answer:

Brooke runs the fastest.

Step-by-step explanation:

Brooke runs 13 feet per second.

Therefore, speed of Broke = 13 feet per sec.

Will runs 308 feet in 26 seconds.

Speed of Will = $\frac{\text{Distance}}{\text{Time taken}}$

= $\frac{308}{26}$

= 11.85 feet per second

Ron runs 1 mile in 551 seconds.

1 mile = 5280 feet

Speed of Ron = $\frac{5280}{551}$

= 9.58 feet per second

Debbie runs 658 feet in 1 minute.

1 minute = 60 seconds

Speed of Debbie = $\frac{658}{60}$

= 10.97 feet per seconds

Here, speed of Brooke is the maximum.

Therefore, Brooke runs the fastest.
