What is 9/11=?/22 need help with this problem

Answers

Answer 1

Answer: When you solve proportions, you have to cross multiply.

   9   x
  --- = --- Multiply each numerator by the opposite denominator.
  11 22

(9)(22) = 11x Then, multiply.

198 = 11x Then, divide.

18 = x

Okay so I'm trying to find the volume of a sphere with the radius of 3/4k. When I cube 3/4 do I only cube the top number?

Answers

No, you cube all of the numerator and denominator. This is because when you cube anything you do the number multiplied by the number 3 times. So you do the same with fractions.
$(3)/(4) * (3)/(4) * (3)/(4) = (3)/(4) ^(3)$

What is the standard equation of the circle in the graph?

Answers

Answer:

Standard Equation Of Circle is $(x-h)^2+(y-k)^2+r^2$

Step-by-step explanation:

Let we are given a circle in graph with center P whose coordinate are ( h , k ) and radius of the circle is r units.

Then the standard equation of circle is written as ,

$(x-h)^2+(y-k)^2=r^2$

If center becomes origin then, Equation become

$x^2+y^2=r^2$

x^2 + y^2 = radius^2
Is that what your adking for? This is for a circle around the origin.

Where does f(x)=3x2-11x-4 intersect the x axis?The negative x-intercept is at (___,0)
The positive x-intercept is at (___,0)

Answers

we know that

The x-intercept is the value of x when the value of the function is equal to zero.

in this problem we have

$f(x)=3x^(2)-11x-4$

To find the x-intercepts equate the function to zero

$3x^(2)-11x-4=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$3x^(2)-11x=4$

Factor the leading coefficient

$3(x^(2)-(11x/3))=4$

Complete the square. Remember to balance the equation by adding the same constants to each side

$3(x^(2)-(11x/3)+(121/36))=4+(121/12)$

$3(x^(2)-(11x/3)+(121/36))=(169/12)$

$(x^(2)-(11x/3)+(121/36))=(169/36)$

Rewrite as perfect squares

$(x-(11/6))^(2)=(169/36)$

square root both sides

$(x-(11/6))=(+/-)(13/6)$

$x=(11/6)(+/-)(13/6)$

$x=(11/6)+(13/6)=24/6=4$

$x=(11/6)-(13/6)=-2/6=-1/3$

therefore

the answer is

The negative x-intercept is at $(-1/3,0)$

The positive x-intercept is at $(4,0)$

The negative x-intercept is (-1/3, 0) and the positive x-intercept is (4,0)

Intercepts

Given the expression 3x²-11x-4, the x intercept occur that the point where f(x) = 0.

The function will become 3x²-11x-4 = 0

factorising expressions

Factorize the result to have:

3x² -12x + x - 4 = 0

Group the function to have;

(3x²-12x)+(x-4) = 0

Factor out the GCF

3x(x-4) + 1(x-4) = 0

(3x+1) (x-4) = 0

Get the x-intercepts

3x+1 = 0

x = -1/3

Hence the negative x-intercept is (-1/3, 0)

Also, x-4 = 0

x = 4

Hence the positive x-intercept is (4, 0)
