So here, you just put in the value inside the parenthesis of the function into the actual function itself.

Here, for h(f(2)), the first one to put in is the one in f, which is 2.

Since f(x) = 3*2^x, and since x here is equal to 2, (because h(f(2)), we can just put in the 2 in place of the x.

3 * 2 ^ 2

And then you get:

3 * 4

Or 12.

So now you have

h(12)

Now do the same thing.

2 * 12 - 7

24 - 7

17

Answer: $569.91\ ft^2$

Step-by-step explanation:

From the given picture, the radius of the base of the cylinder = 5.5 ft.

The height of the cylinder = 5 ft.+6 ft.=11 ft.

We know that the surface area of a cylinder is given by :-

$\text{Surface Area}=2\pi r (r+h)\\\\\Rightarrow\text{Surface Area}=2(3.14)(5.5)(5.5+11)\\\\\Rightarrow\text{Surface Area}=569.91\ ft^2$

Hence, the surface area of the given cylinder = $569.91\ ft^2$

Find the results combining these functions.

vodomira [7]

Given $f(x) = x^2 + 6x + 9, g(x) = x^2 - 9$ :

$(f+g)(x) = (x^2 + 6x+9)+(x^2-9) =2x^2+6x=2x(x+3)$ , which is the second expression

$(f-g)(x) = (x^2 + 6x+9)-(x^2-9) =6x+18=6(x+3)$ , which is the first second expression

$(fxg)(x) = (x^2+6x+9)(x^2-9) = (x^4-9x^2)+(6x^3-54x)+(9x^2-81)=x^4+6x^3-54x-81$ , which is the fourth expression

$(f/g)(x) = (x^2+6x+9)/(x^2-9) = \frac{(x+3)^2}{(x+3)(x-3)} = \frac{x+3}{x-3}$ , which is the third expression

Belle is going to make chili for a football party. It will take 1 hour and 10 minutes to prepare all the ingredients and assembl

MrRa [10]

Answer:

1:10pm

Step-by-step explanation:

1st, you add all the time needed to make the chili & cook it.

1 hour + 10 minutes + 1 hour + 40 minutes = 2 hours & 50 minutes.

Now you work backwards from 4:00pm.

You go back 2 hours & you would be at 2:00pm

Now you go back another 50 minutes & you would be at 1:10pm

To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm
