Answer: $\frac{12}{x}$ is an asymptote

Step-by-step explanation:

Apply a table, and plug in values of x into the equation. For example f(2)= $\frac{12}{2} =6$ . That's one of the points on the graph that we just found (2,6)

Finding the inverse function of $f(x) = 5\sqrt{x + 3} - 2$ , it is best described by graph B.

<h3>How to find the inverse of a function?</h3>

Supposing we have a function y = f(x), to find the inverse, we exchange x and y, and isolate y.

In this problem, the function is:

$f(x) = 5\sqrt{x + 3} - 2$

$y = 5\sqrt{x + 3} - 2$

Exchanging x and y:

$x = 5\sqrt{y + 3} - 2$

Working through the function to isolate y:

$5\sqrt{y + 3} = x + 2$

$\sqrt{y + 3} = \frac{x + 2}{5}$

$(\sqrt{y + 3})^2 = \left(\frac{x + 2}{5}\right)^2$

$y + 3 = \frac{(x + 2)^2}{25}$

$y = \frac{(x + 2)^2}{25} - 3$

$f^{-1}(x) = \frac{(x + 2)^2}{25} - 3$

Which is best represented by graph B.

Part A: Vertical asymptote is $x=0$

Part B: Domain is $\left(-\infty \:,\:0\right)\cup \left(0,\:\infty \:\right)$

Part C: Horizontal asymptote is $y=4$

Part D: Range is $\left(-\infty \:,\:4\right)\cup \left(4,\:\infty \:\right)$

Explanation:

Part A: We need to determine the vertical asymptote

The vertical asymptote of a function can be determined by equating the denominator equal to zero.

Thus, we have,

$x=0$

Hence, the vertical asymptote is $x=0$

Part B: We need to determine the domain

The domain of the function is the set of all independent x - values for which the function is real and well defined.

Let us take the denominator and equate to zero.

Hence, we have, $x=0$

Therefore, the function is undefined at the point $x=0$

Thus, the domain of the function is $\left(-\infty \:,\:0\right)\cup \left(0,\:\infty \:\right)$

Part C: We need to determine the horizontal asymptote

The horizontal asymptote of the function can be determined by dividing the leading coefficient of the numerator by leading coefficient of the denominator.

Thus, we have, $y=4$

Hence, the horizontal asymptote of the function is $y=4$

Part D: We need to determine the range

The range of the function is the set of all dependent y -values of the function.

In other words, the range of the function can be determined by substituting the values for x.

Thus, we have,

$\left(-\infty \:,\:4\right)\cup \left(4,\:\infty \:\right)$

Therefore, the range of the function is $\left(-\infty \:,\:4\right)\cup \left(4,\:\infty \:\right)$

During a race, Bernie ran 9meters every 4 seconds, while Wendel ran 2 meters every second and got a 9-meter head start. If the r

sdas [7]

Answer:

Step-by-step explanation:

No, because Bernie had to run 9 meters 7.77777778 time (70/9) and each of those 9-meter sections took 4 seconds, so her time was 31.1111111 (7.77777778*4). While Wendel had to run 61 meters 70-his headstart (9 meters) (70-9). So he only had to run 30.5 blocks of 2 meters (61/2). And since they're only 1 second long, it's 30.5*1=30.5.

So the answer is a NO because (Bernie) 31.1111111 seconds > 30.5 seconds (Wendel).

Find the area of the complex figure below.

xxTIMURxx [149]

Ok so you have to do the area of three different shapes then add them together so to find the area for the square and rectangle you need to find the sides to be equal so the square is already set you would do 6 times 5 and get 30 so how to do the rectangle is add 7 and 5 and get 12 so you would do 10 - 6 and get 4 and then do 12 times 4 which is 48 so, so far you have 78 for an area but you a triangle so you have a base of 3 because we found that the rectangle is 12 so 15-12 is 3 then we did the side for the rectangle which was 10-6 is 4 so for the triangle you would do 1/2 times 3 times 4 which would be 6 so 78 plus 6 and you would get 84 so A is your answer
