Answer:

The square root function is the inverse of the squaring function just as subtraction is the inverse of addition. ... The square root could be positive or negative because multiplying two negative numbers gives a positive number. The principal square root is the nonnegative number that when multiplied by itself equals a.

Step-by-step explanation: Hope this helps!!!  Have a good day!!

Answer:

The average rate of change between these times is 68 miles per hour

Step-by-step explanation:

Here, we are to determine the average rate of change between hour 2 and hour 7

The distance traveled at hour 2 is 140 miles

The distance traveled at hour 7 is 480 miles

So we can say we have two points and we want to know the rate of change between these points

Mathematically, we can represent the rate of change as Δ

Thus, between the two different times, we have;

Δ = (D7-D2)/(T7-T2)

where (T7,D7) = (7,480) and (T2,D2) = (2,140) represents the time and distance at hour 2 and hour 7 respectively

Now inputing the values into the equation, we have;

Δ = (480-140)/(7-2) = 340/5 = 68 miles/hour

An inequality can be formed by simply translating the problem statement to numerical expressions.

From the problem we know that 3w added with 52 hours should be equal or greater than 90 (helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

3w+52>=90 (>= is used instead of ≥ for constraints in formatting)

The inequality above best models the situation.
