Which statements about the hyperbola are true? Check all that apply.

never [62]

Answer:

Only option A is correct.

Step-by-step explanation:

From the given figure it is noticed that the vertices of hyperbola are (0,8) and (0,-8). It is a vertical hyperbola.

It means a=8.

From the rectangle we can say that the value of b is 6.

$c^2=a^2-b^2$

$c^2=(8)^2+(6)^2$

$c^2=100$

$c=10$

The focus of a vertical hyperbola are (0,c) and (0,-c). So, the focus of hyperbola are (0,10) and (0,-10).

Therefore option A is correct.

Asymptotes of a vertical hyperbola are

$y=\pm \frac{a}{b}x$

$y=\pm \frac{8}{6}x$

$y=\pm \frac{4}{3}x$

Directrix of a vertical hyperbola are

$y=\pm \frac{a^2}{c}$

$y=\pm \frac{(10)^2}{6}$

$y=\pm \frac{50}{3}$

Only option A is correct.

If f(x)=2x^3-6x^2-16x-20f(x)=2x *3 −6x *2−16x−20 and f(5)=0, then find all of the zeros of f(x)f(x) algebraically.

mihalych1998 [28]

The zeros of the cubic function f(x) = 2x³ - 6x² - 16x - 20 are given as follows:

x = 5, x = -1 + i, x = -1 - i.

<h3>How to obtain the solutions to the equation?</h3>

The equation is defined by the rule presented as follows:

f(x) = 2x³ - 6x² - 16x - 20.

One solution for the equation is given as follows:

x = 5.

Because f(5) = 0.

Then (x - 5) is a linear factor of the function f(x), which can be written as follows:

2x³ - 6x² - 16x - 20 = (ax² + bx + c)(x - 5).

This is because the product of a linear function and a quadratic function results in a cubic function.

Now we expand the right side to begin finding the coefficients of the quadratic function that we are going to solve to find the remaining zeros:

2x³ - 6x² - 16x - 20 = = ax³ + (b - 5a)x² + (c - 5b)x - 5c.

Then these coefficients are obtained comparing the left and the right side of the equality as follows:

a = 2.

-5c = -20 -> c = 4.

b = -6 + 5a = 4.

Hence the equation is:

2x² + 4x + 4.

Using a quadratic equation calculator, the remaining zeros are given as follows:

x = -1 + i.

x = -1 - i.

Help me!!! What is a equation for this?!?! 25% of 64 Not proportion

vodka [1.7K]

Percent means parts out of 100
so 25%=25/100=5/20=1/4

'of' means multiply

so 25% of 64 means
1/4 times 64 or
64/4 or
32/2 or
16

Im trying to solve this but don’t understand how m-3(-5x+2)+x=42

timofeeve [1]

-3(-5x+2)+x=42
Distribute the -3 to the -5 and 2 so you would be left with
15x-6+x=42
Then you combine like terms and the x’s
16x-6=42
Add the 6 to the 42
16x=48
Then divide by 16 on both sides
X=3

I hope that helped.
