Answer:

The mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

Step-by-step explanation:

Given the expression

42x = 163

To get the values of x, we are to divide both sides by the coefficient of x i.e 42 as shown;

42x = 163

42x/42 = 163/42

x = 163/42

x = 3.88

Hence the mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

Answer:

$t=-10\log 0.32$

Explanation:

<u>Equation:</u>

$A=1,562.5\times 10^{(-0.1t)}$

This is a decaying exponential function, because the exponent is negative.

Then, the larger the value of t (number of months), the smaller A (the number of hectares).

The factor 1,562.5 is the initial number of hecares, when t = 0.

You must find the value of t when A equals 500, thus solve the equation:

$500=1,562.5\times 10^{(-0.1t)$

Divide both sides by 1,562.5

$\dfrac{500}{1,562.5}=10^{(-0.1t)}$

$0.32=10^{(-0.1t)}$

Take base-10 logarithms on both sides:

$\log 0.32=-0.1t$

$t=-\dfrac{\log 0.32}{0.1}\\\\\\t=-10\log 0.32$

Note that the logarithm of a number decimal number is negative number, thus t will be positive. When you compute that, it is about 4.9 months.
