MATH: Composition of two functions...help needed with this problem

The equation of Q(n) is $Q(n) = \frac89 * (88n + 23)$

<h3>How to determine the formula of Q(n)?</h3>

The functions are given as:

$R(d) = \frac89 d$

$P(n) = 88n + 23$

From the question, we understand that:

d = P(n)

This means that:

d = 88n + 23

Substitute d = 88n + 23 in R(d)

$R(n) = \frac89 * (88n + 23)$

Also, from the question

Q(n) = R(n)

So, we have:

$Q(n) = \frac89 * (88n + 23)$

Hence, the equation of Q(n) is $Q(n) = \frac89 * (88n + 23)$

Adante begins to evaluate the expression 3 1/3 * 5 1/4

goldenfox [79]

For this case we must find the product of two mixed numbers:

$3 \frac {1} {3} = 3 + \frac {1} {3} = \frac {9 + 1} {3} = \frac {10} {3}\\5 \frac {1} {4} = 5 + \frac {1} {4} = \frac {20 + 1} {4} = \frac {21} {4}$

So, we have:

$\frac {10} {3} * \frac {21} {4} = \frac {10 * 21} {3 * 4} = \frac {210} {12} = \frac {105} {6} = \frac {35} {2}$

If we go to a mixed number we have:

$\frac {35} {2} = 17 \frac {1} {2}$

Answer:

$17 \frac {1} {2}$
