F(x) = V2x<br> g(x) = V18x<br> Find (f .g)(x). Assume x2 0.
Nina [5.8K]

Answer:

fog(x) is D = 6\sqrt{x}

Step-by-step explanation:

I. square all value, so f(x) is 2x then g(x) is 18x

II. Replace x.value in f(x) with g(x).value = 2(18x)

III. If x is 1, 2(18*1) will be 36; find root, so answer is 6

If x is 2, 2(18*2) will be 72; find root, so answer is 6\sqrt{2}

Hope it help, sorry if I'm done it wrong, but I think it's gonna be the right answer. :)

Solve this inequality and write the solution using interval notation:
grandymaker [24]

The solution to the inequality in discuss involving a rational expression as indicated in the task content is; t (9, infinity).

<h3>What is the solution to the inequality as indicated in the task content in which case, the solution is expressed using interval notation?</h3>

The inequality given in the task content as evident is; (2t +22)/(2t +2) <= 2.

On this note, the inequality can be solved by cross-multiplication as follows;

2t +22 <= 4t +4

Hence, we have;

-2t <= -18

t >= 9.

Hence, when expressed as an interval notation, we have; t (9, infinity).

Use a net to find the surface area of the cone to the nearest square centimeter. Use 3.14 for pi.
Lerok [7]

The surface area of the cone is given by:

SA=\pi r^2+\pi Lr

where r is the radius and L is slant height.

In this case r=5 and L=12. Then the surface area is:

\begin{gathered} SA=(3.14)(5)^2+(3.14)(12)(5) \\ =267 \end{gathered}

Therefore the surface area is 267 squared centimeters,
