EastWind [94]
For x\neq a, we have

\dfrac{x^2-a^2}{x-a}=\dfrac{(x-a)(x+a)}{x-a}=x+a

So for g(x) to be continuous at x=a, we require that the limit as x\to a is equal to 4.

\displaystyle\lim_{x\to a}g(x)=\lim_{x\to a}(x+a)=2a=4\implies a=2

Which phrase describes a nonlinear function?
Lorico [155]
The only non-linear equation from your choices is the area of a circle as it is:

A=πr^2  and if you take the derivative of A you have:

dA/dr=2πr

So the rate of change changes as r changes, it is not constant thus the function has acceleration, so velocity changes.

This is in contrast to any linear equation which is of the form:

y=mx+b  now taking the derivative you see that:

dy/dx=m, now m is a constant value, which means that there is no acceleration and the velocity remains constant.

Alina is able to swim at a rate of about 2.5 miles per hour. Talia is able to swim at a rate of 1.8 meters per second. Which sta
Masja [62]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Rate at which Alina swim = 2.5 miles per hour

Rate at which Talia swim = 1.8 meters per second

First we need to change meters per second into miles per hour

As we have given that

1\text{ miles}=1609\text{ meters}

and

1\text{ hour}=3600\text{ seconds}

So, to change into miles per hours, we'll apply this,

\frac{1.8\times 3600}{1609}\\\\=4.02\text{ miles per hour}

So,

Difference between their rates will be given by

4.02-2.5=1.52\text{ miles per hour}

Hence, Talia swims about 1.5 miles per hour faster than Alina.

So, Option 'D' is correct.
