Answer:

x < -8¼ or x > 9

Step-by-step explanation:

|8x - 3| > 69

8x - 3 > 69

8x > 72

x > 9

-8x + 3 > 69

-8x > 66

x < -66/8

x < -8¼

x < -8¼ or x > 9

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.

What is the volume of the sphere?
poizon [28]

Answer: 113.1

Step-by-step explanation:

The formula is \frac{4}{3}\pir^{3}

The radius is 3, and 3 cubed is 27.

Then, 27 x \pi is about 84.82

Finally, 84.82 x \frac{4}{3} is about 113.1

Hope this helps. Please mark as brainliest, thanks!
