At the carnival, 3 rides on the MoonCoaster cost $21. How much<br> do 5 rides cost?

Bogdan [553]

Answer:

$35 dollars

Step-by-step explanation:

So we know that 3 rides costs $21. If you then take 21/3 you get 7, you're then going to take 7x5 and you will get 35. Therefore 5 rides on the MoonCoaster cost $35. Hope this helps!

Consider the quadratic equation below. 4x^2-5=3x+4 Determine the correct set-up for solving the equation using the quadratic for

lidiya [134]

$4x^2-5=3x+4$

$4x^2 - 3x - 5 - 4 = 0$

$4x^2 - 3x -9 = 0$

$x= \dfrac{3 \pm \sqrt{3^2 - 4(4)(-9)}}{2(4)}$

$x = \frac 1 8 (3 \pm \sqrt{9(1 + 16)})$

$x = \frac 1 8 (3 \pm 3\sqrt{17})$

Find Horizontal and Vertical Asymptotes for y=(1)/((x+2)^3)

Usimov [2.4K]

Answer:

Vertical asymptote: $x = -2$

Horizontal asymptote: $y = 0$ or x axis.

Step-by-step explanation:

The rational function is given as:

$y=\frac{1}{(x+2)^3}$

Vertical asymptotes are those values of $x$ for which the function is undefined or the graph moves towards infinity.

For a rational function, the vertical asymptotes can be determined by equating the denominator equal to zero and finding the values of $x$ .

Here, the denominator is $(x+2)^3$

Setting the denominator equal to zero, we get

$(x+2)^3=0\\(x+2)=0\\x=-2$

Therefore, the vertical asymptote occur at $x=-2$ .

Horizontal asymptotes are the horizontal lines when $x$ tends towards infinity.

For a rational function, if the degree of numerator is less than that of the denominator, then the horizontal asymptote is given as $y=0$ .

Here, there is no $x$ term in the numerator. So, degree is 0. The degree of the denominator is 3. So, the degree of numerator is less than that of denominator.

Therefore, the horizontal asymptote is at $y=0$ or x axis.
