Rena used the steps below to evaluate the expression (StartFraction (x Superscript negative 3 Baseline) (y Superscript negative

2 Baseline) Over 2 (x Superscript 4 Baseline) (y superscript negative 4 Baseline) EndFraction) Superscript negative 3, when x = negative 1 and y = 2. Step 1: Substitute x = negative 1 and y = 2 into the expression. (StartFraction (negative 1) Superscript negative 3 Baseline (2) Superscript negative 2 Baseline Over 2 (negative 1) Superscript 4 Baseline (2) superscript negative 4 Baseline) EndFraction) Superscript negative 3 Step 2: Simplify the parentheses. (StartFraction (2) Superscript 4 Baseline Over 2 (negative 1) Superscript 4 Baseline (negative 1) cubed (2) squared EndFraction) Superscript negative 3 Baseline = (StartFraction (2) squared Over 2 (negative 1) Superscript 7 Baseline EndFraction) Superscript negative 3 Step 3: Evaluate the power to a power. StartFraction (2) Superscript negative 6 Baseline Over 2 Superscript negative 3 Baseline (negative 1) Superscript negative 21 baseline EndFraction Step 4: Use reciprocals and find the value. StartFraction 1 Over 2 cubed (2) Superscript 6 Baseline (negative 1) Superscript 21 Baseline EndFraction = StartFraction 1 Over 8 times 64 times (negative 1) EndFraction = Negative StartFraction 1 Over 512 EndFraction In which step did Rena make the first error?

The population of Hannah’s town increased from 1,500 to 2,600 in five years. At what rate is the population increasing?
puteri [66]

The population is increasing at the rate of 220

Explanation:

Given that the population of Hannah's town is increased from 1500 to 2600 in five years.

This can be written in expression as

f(0)=1500  and

f(5)=2600

We need to determine the rate of change of population.

The rate of change can be determined using the formula,

\frac{f(b)-f(a)}{b-a}

where a=0 and b=5

Substituting the values in the formula, we have,

\frac{2600-1500}{5-0}

Simplifying, we have,

\frac{1100}{5}

Dividing, we get,

220

Thus, the population is increasing at the rate of 220

Work out m and c for the line: <br>y = 9x​
Katen [24]

The Equation is already written in the form y=mx+c there is nothing to solve

The m is the coefficient of the equation only if the equation is written in the general form y=mx+c

judging from the given equation m=9 and c=0

I hope I helped you.
