Answer:
452 cubic inches
Step-by-step explanation:
In terms of diameter, the volume of the cylinder is ...
V = (π/4)d^2h
Filling in the given numbers, we get ...
V =(3.14/4)(8 in)^2(9 in) = 452.16 in^3
The cylinder volume is about 452 cubic inches.
If you change 3^x to 3^(x+4) you get

Step-by-step explanation:
I won't be answering all of them because that's a lot, but I'll try and help you on how to do them.
So, factorising means you put the equation into brackets.
The easiest way to work these out would be to look at the pairs of numbers that multiply to make the last number in the equation (so for 2a: 1x2 is the only option, for 2b: 1x4, 2x2, 4x1 for 2c: 1x30, 2x15, 3x10, 5x6 etc)
The next step is to look at the pairs and see which ones could add or subtract to make the number in the middle of the equation
(So for 2a: 1+2=3, 2b: 1+4=5, 2c: 3+10=13)
Then put those numbers into the brackets, with the + or - that you just did
So 2a: (x+1)(x+2)
2b: (m+1)(m+4)
2c: (a+3)(a+10)
etc

<u><em>The correct answers are: </em></u>1) f(x)=1/2x;
2) f(x)=2x+1;
3) f(x)=x^3;
4) f(x)=6x.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>Let x be the input. In function notation, the output is denoted by f(x).
For #1, since the output is half of the input, we want to take half of x; this would give us
f (x)=</span></span>
<span><span>x.
For #2, twice the input is 2x; one more than this is 2x+1, which gives us
f (x)=2x+1.
For #3, the cube of the input is x</span></span>³<span><span>, which gives us
f (x)=x</span></span>³<span><span>.
For #4, six times the input is 6x, which gives us
f (x)=6x.</span></span>
