The sum or product of a non-zero rational number and an irrational number is always

Anarel [89]

Answer:

Irrational

Step-by-step explanation:

A rational number and an irrational number when added will given another irrational number only.

Example consider a rational number 2 and an irrational number √3.

When we add these two we get

2+√3. an irrational number only

There is no chance of getting a rational number when a non zero rational and irrational is added. In other words, there is nothing to cancel the irrational part when another rational number is added.

Hence the result would be irrational

Thus answer is irrational.

.Calculate the average rate of change of f(x) = 3x + 4 on the interval [2, 6]. Select any oth

makvit [3.9K]

Answer:

Average rate of change= 3

Step-by-step explanation:

Recall the definition of average rate of change of a function $f(x)$ in an interval $[a,b]$ :

Average rate of change = $\frac{f(b)-f(a)}{b-a}$

In your case:

$f(x) = 3x+4$ , and the interval $[a,b]$ i $[2,6]$ , therefore:

Average rate of change = $\frac{f(6)-f(2)}{6-2}=\frac{f(6)-f(2)}{4}$

Now we evaluate the function at the two requested points:

$f(x)=3x+4\\f(6)=3(6)+4=18+4=22\\f(2)=3(2)+4=6+4=10$ , then $f(6)-f(2)=22-10=12$

So finally the Average rate of change is: $\frac{f(6)-f(2)}{6-2}=\frac{12}{4} =3$
