What is the approximate value of this logarithmic expression?
Licemer1 [7]

The approximate value of log_{8}24 is 1.52832 or 1.53.

What is the logarithmic Expression?

A logarithmic expression is an function that involves the logarithm of an expression containing a variable. To solve exponential equations, first see whether you can write both sides of the equation as powers of the same number.

Here log_{8}24 = log_{2^{3} }24

                   = \frac{1}{3} log_{2}24

                   = \frac{1}{3} log_{2}{8.3}

                   = \frac{1}{3} log_{2}8 + \frac{1}{3} log_{2}3

                   = \frac{1}{3} log_{2}2^3 + \frac{1}{3} log_{2}3

                   = \frac{3}{3} log_{2}2 +\frac{1}{3} log_{2}3

                   =  1 + \frac{1}{3} log_{2}3

                   = 1 + 0.5283

      llog_{8}24  ≈ 1.53

The approximate value of log_{8}24  is 1.52832 or 1.53.

Jamal wants to install a rectangular 2025 cm² window in his garden shed. That area of window comes in several length/width combi
frosja888 [35]

Answer:

The ideal size will be a 45cmx45cm square, giving you a perimeter of 180cm.

Step-by-step explanation:

The shortcut answer here is that the square will always be the most efficient rectangle for border to area, so the sides should be the square root of 2025 cm, or 45 cm each, giving you a total of 180 minimum perimeter.

The full solution is to express the perimeter as a function of the length and width, define either length or width as a function of the other, take the entire expression's derivative and solve for zero.  Let's do it:

So first the area:

2025 = wl

l = 2025 / w

Now the sides:

p = 2w + 2l\\p = 2w + 2(2025 / w)\\p = 2w + 4050 / w

Then we can take its derivative with respect to w

p = 2w + 4050\frac{1}{w}\\\frac{dp}{dw} = 2 + 4050\frac{-1}{w^2}\\

Now we can set the derivative to zero, and solve for w:

\frac{dp}{dw} = 2 + 4050\frac{-1}{w^2}\\0 = 2 + \frac{-4050}{w^2}\\-2 =  \frac{-4050}{w^2}\\2w^2 = 4050\\w^2 = 2025\\w = \sqrt{2025}\\w = 45

So the width being 45, we can get the length by dividing the area by that amount, which of course is also 45.

valina [46]
<span>x = number of domestic stamps

y = number of foreign stamps

Malik collects rare stamps and has a total of 212 stamps.
 
=> x + y = 212

he has 34 more domestic stamps than foreign stamps.

=> x = y + 34


which equation represents the total number of stamps malik collected?

x + y = 212

which equation represents the difference in the number of foreign and domestic stamps malik collected?

x - y = 34

which system of linear equations represents the situation?

x + y = 212
x - y = 34
