What is the average rate of change for this function for the interval from x=3 to x=5

sveta [45]

Answer:

A. 16

Step-by-step explanation:

We have to find rate of change of function from x=3 to x=5

The average rate of change for the interval a≤x≤b is given by:

Rate of change= (f(b)-f(a))/(b-a)

In our question,

a=3

and

b=5

We can see from the table that at x = 3, the value of function is 18

So,

f(a)=18

and

At x=5, the value of function is 50

f(b)=50

Rate of change=(50-18)/(5-3)

=32/2

=16

So the rate of change of function between x=3 and x=5 is 16 ..

Option A is the correct answer..

Given the following sets.

Solnce55 [7]

$A=\{0,\ 1,\ 2,\ 3\}\\\\B=\{a,\ b,\ c,\ d\}\\\\A\ \cap\ B=\O\ (empty\ set)$

The intersection of A and B, denoted by A ∩ B, is the set of all things that are members of both A and B.

The ratio of the number of men to the number of women in a sports club is 5:2.

user100 [1]

Let the number of men and the number of women in the beginning be x and y

Now, $\sf \frac{x} {y} =\frac{5}{2} \\\\\sf=2x=5y \\\\\sf=x=\frac{5y}{2}$

Now, In 2nd case,

No. Of men=x-63 and no. Of women =y-12

Now,the ratio becomes $\frac{x-63}{y-12}=\frac{7}{4} \\\\\sf=4(x-63)=7(y-12) \\\\\sf=4x-252=7y-84 \\\\\sfPutting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf10y-252=7y-84 \\\\\sf=10y-7y=252-84 \\\\\sf=3y=168 \\\\\sf=y=56 \\\\\sf=\boxed{Y=56}$

Now,we have, 2x=5y

Putting the value of Y=56 in 2x=5y,we get,

$\sf 2x=5\:x\:56 \\\\\sfx=\frac{5\:x\:56}{2} \\\\\sfx=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf=x=5\: x\: 28 \\\\\sfx=140 \\\\\sf\boxed{x=140}$
