Two cars start at the same point and travel in the same direction at average speeds of 70 miles per hour and 40 miles per hour.D
crimeas [40]

The two cars will be 105 miles apart in 3.5 hours.

We can determine this by realizing that the net difference in their speed is 30 miles per hour (70mph - 40mph). This means that every hour that passes, car A moves 30 miles away from car B. To determine the final time, we can divide the total goal distance by the rate.

105miles/30mph = 3.5 hours.

Determine algebraically whether the function is even, odd, or neither even nor odd.
AfilCa [17]

Answer:

Given Function is an even function

Step-by-step explanation:

<u>Explanation</u>:-

<u>Even function</u> :-

A function f is even if the graph of f is symmetric with respective to the y - axis.

Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f.

<u>Odd function</u> : -

A function f is odd if the graph of f is symmetric with respective to the origin

Algebraically, f is odd if and only if f(-x) = - f(x) for all x in the domain of f.

given function is f(x) = 3 x^2-1

f(-x) = 3 (-x)^2-1=3 x^2 -1 = f(x)

therefore f(-x) = f(x)

given function is an even function.
