Answer:

(2^-14 * 5^10)

Step-by-step explanation:

(2^-7 * 5^5)^2

From.the law of indices :

(a^m)^n = a^mn

Such that we multiply both powers

Hence the equation, W will become :

2^(-7*2) * 5^(5*2) = (2^-14 * 5^10)

Jack is mowing a lawn that has a shed. needs to know area of lawn to mow. dimensions of yard are 5x by 13 x-4 . she'd are 2x by

Elena-2011 [213]

The diagram of the lawn and the shed is shown below.

The area of the lawn needed to be mowed equals to the area of the yard minus the area of the shed

The area of the yard = $(5x)(13x-4) = 65 x^{2} -20x$
The area of the shed = $(2x)(2x+4)=4 x^{2} +8x$

The area of the lawn = $65 x^{2} -20x-(4 x^{2} +8x)$
The area of the lawn = $65 x^{2} -20x-4 x^{2} -8x$
The area of the lawn = $61 x^{2} -28x$

A candle burned at a steady rate. After 33 minutes, the candle was 11.2 inches tall. Eighteen minutes later, it was 10.75 inches

Amiraneli [1.4K]

Answer:

9.025 inches

Step-by-step explanation:

Let the length be represented by:

$L = mt+L_0$

Where $L$ is the length of candle at time $t$

$m$ is the rate at which the candle is burning.

And $L_0$ is the initial length of the candle.

As per the question statement, let us put the given values in the equation.

$11.2 = m\times 33 + L_0 .... (1)\\10.75 = m\times 51+L_0 ..... (2)$

Subtracting (1) from (2):

$0.45 = -18m\\\Rightarrow m = -0.025$

Putting the value of $m$ in the equation (1):

$11.2 = -0.025 \times 33+L_0\\\Rightarrow L_0 = 12.025$

Therefore, the equation becomes:

$L = -0.025t + 12.025$

Now, we have to find the height of candle after 2 hours.

2 hours mean 120 minutes.

$L = -0.025 \times 120 + 12.025\\\Rightarrow L = 9.025\ inches$

Therefore, the height of candle is <em>9.025 inches</em>.
