second question:
January: 32 · 22 + 38 · 18 = 704 + 684 = 1388
December: 18 · 22 + 40 · 18 = 396 + 720 = 1116
1388 - 1116 = 272
Answer: $272.
Follow these 3 steps to convert a mixed number to a percent:<span>1. Convert the fraction part of the mixed number to a decimal: Divide the numerator by the denominator.
2. Add the decimal to the whole number part of the mixed number.
<span>3. Convert the decimal to a percent: Multiply the decimal number by 100.</span></span>
The function f (x) = x ^ 2 - 2 is given
It is asked to find the graph of f (5x)
So where the x goes we must now place "5x"
In this way the function is as shown below:
f (5x) = (5x)² -2
f (5x) = 25x² -2
The graph of this function is shown in the attached image.
Answer: 512MB of Memory
Step-by-step explanation:
How I approach solving a problem such as this is:
First, I start with what I like to call the "knowns". So we know the available memory left on the computer after the installing the new software is:
475.2MB
2.) Once I have my first "known" identified I write it down on a piece of paper. The next thing I do is look for any more remaining "knowns" in the problem. With this particular problem we see that the second and final "known" is of course the 36.8MB of memory the newly installed software used. So I take the 36.8MB and I add it to the amount of memory remaining on the computer after installing the new software. We already identified the amount of memory remaining as 475.2
On paper for example, it should look something like this:
475.2
+ 36.8
Once you add those two numbers together you get 512.
Lastly, you just need to add abbreviation "MB" immediately after the number 512. Once that has been done, you are left with the correct amount of Memory the computer had available before installing the new software, which is:
512MB
I hope I was clear and consise enough with that explanantion. Good luck to you!
Step-by-step explanation:
A number between points A and B is number -0,5 or we can write it -1/2
First, you find a average and solve that
= (A + B) ÷ 2
= (-0,8 + -0,2) ÷ 2
= -1,0 ÷ 2
= -1 ÷ 2
= -1/2 or -0,5
Option → C
