Which expression is equivalent to the given expression? Assume the denominator does not equal zero.
ipn [44]

The expression equivalent to given expression is \frac{b^4}{a}

<em><u>Solution:</u></em>

Given expression is:

\frac{a^3b^5}{a^4b}

We are asked to find the expression equivalent to given expression

Assume that denominator does not equal to zero

We can apply the exponent rule in given expression

\frac{x^a}{x^b} = x^{a - b}

Apply the above rule in given expression

\frac{a^3b^5}{a^4b} = a^{3-4} \times b^{5-1} = a^{-1}b^4

a^{-1}b^4 = \frac{b^4}{a}

Thus the equivalent expression is found

What is the average rate of change for this function for the interval from x= 1
Usimov [2.4K]

Answer:

  C. 8

Step-by-step explanation:

The average rate of change is the slope of the line between the two points of interest. It is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

For points (1, 2) and (3, 18), the average rate of change is ...

  m = (18 -2)/(3 -1) = 16/2 = 8

The average rate of change between x=1 and x=3 is 8.

40 POINTS AND BRAINLIEST
ladessa [460]

Answer:

120

Step-by-step explanation:

As x goes from 1 to 2, y increases by 4 from 4 to 8

As x goes from 2 to 3, y increases by 4 from 8 to 12

We increase by 4 each time

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term which is 4

d is the common difference or the number we add each time which is 4

n is the term we are looking for which is 30

a30 = 4 +4 (30-1)

a30 = 4+4(29)

       = 4+116

      = 120
