Its A because whenever you see f(x), whatever is in the parenthesis is substituted for x. So if it were f(x)= x and you had to find f(3) then you would plug in the three for x then f(3)=3. The same goes for this. You plug in the whole equation of f(x) into the x in g(x). Since g(x) is just x^2 then you plug in the x-5 and that would be g(f(x))=(x-5)^2. I hope that helped I'm not very good at explaining.

If a grade is 75 of your grade you got 80 what is your final.grade

evablogger [386]

You have to find the mean.

Add up all the points from the assignments and the 80.

Then Divide. For example, if there are 23 assignments in the grade book, divide by 23.

Now you have your final grade.

Example: 80+ 76 + 59 + 79 = 294
There are four assignments so you divide by four: 294÷4= 73.5
Final grade is 73.5

I hoped this helped.

25.Work out the volume of this prism?<br> Please help in for tomorrow

vodomira [7]

Volume equal area of base time height

so than we consider the base this triangle for what is given area and in this way we have the height equal this edge with length equal 6 so the volume will be equal 12*6=72 m^3

hope this is understandably sure easy and will help you

in chemical formulas, there are often subscript numbers (such as the 2 in h2o, or the 6, 12, and 6 in c6h12o6). what do these su

Gnesinka [82]

In a Chemical formula, Subscript figures tell us how numerous of the element to their upper-left there are in the patch.

What is a chemical formula?

In chemistry, a chemical formula is a way of presenting information about the chemical proportions of titles that constitute a particular chemical emulsion or patch, using chemical element symbols, figures, and occasionally also other symbols, similar as hiatuses, dashes, classes, commas, and plus() and disadvantage( −) signs.
These are limited to a single typographic line of symbols, which may include subscripts and subtitles.
A chemical formula may indicate certain simple chemical structures, it isn't the same as a full chemical structural formula.

The subscript number indicates the total number of titles of an element present in a patch.

While witting a chemical formula, first we've to write the symbol of an element and also write the number at the bottom of the symbol.

For illustration,

$C_6H_{12}O_6$ is the chemical formula of the glucose patch. The glucose patch is made up of six carbon titles, twelve hydrogen titles, and 6 oxygen titles.

The number 6 of the carbon snippet is written after and at the bottom ( lower- right) of the symbol of carbon element (C). also, the number 12 is written lower-right of the symbol of hydrogen element (H), and the number 6 is written lower-right of the symbol of oxygen element( O).

thus, the subscript figures tell us how numerous of the element to their upper-left there are in the patch.
