Answer:

Not necessarily. If picture is drawn to scale, no.

Step-by-step explanation:

Line segment EF is certainly perpendicular to line segment AC, but we don't know if it bisects or not.

If the picture isn't drawn to scale, there is no way to know if EF is a perpendicular bisector to AC or not because we do not know if AD = CD.

If the picture is drawn to scale, EF is not a perpendicular bisector to AC because we can see that AD ≠ CD and therefore EF cannot be a perpendicular bisector.

What is the volume of a hemisphere with a radius of 61.9 m, rounded to the nearest
ZanzabumX [31]

Answer:

The volume of the hemisphere is 496741.6 m³

Step-by-step explanation:

The volume of an sphere is given by:

V_{s} = \frac{4\pi r^{3}}{3}

In which \pi = 3.14 and r is the radius.

An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So

V_{h} = \frac{V_{s}}{2} = \frac{2\pi r^{3}}{3}

In this question:

r = 61.9. So

V_{h} = \frac{2\pi (61.9)^{3}}{3} = 496741.6

The volume of the hemisphere is 496741.6 m³

How do i evaluate a piecewise function
yulyashka [42]

Answer:

Piecewise functions are those where the behavior of the functions is dependent on the value of x.

For example the absolute value function f(x) = |x| is the same as

f(x) = -x , x<0

= x, 0<=x

To evaluate the value of f(x) = |x|, first determine if x is less than 0, equal to 0 or greater than 0. If x is less than 0, the value of |x| is equal to the negative value of x. In all other cases it is equal to the value of x.

This is the simplest piecewise function. There are other more complex functions where the function can take on more than 2 different behaviors based on the value of x.

Piecewise functions can also be identified from their graph. These have breaks in their graph, and each segment has a different behavior that is dependent on the value of x.

The evaluation of piecewise functions is done in the following way.

  • First, look at x and determine from the available behaviors which one would be followed for that particular value of x.
  • Next, we substitute x in that sub-function and determine the value obtained.

This complexity of this process varies with the piecewise function being evaluated. There are many functions which have a graph of infinite pieces.

A piecewise function is a function made up of different parts. More specifically, it’s a function defined over two or more intervals rather than with one simple equation over the domain. It may or may not be a continuous function.

How do I graph 6x - 3y = 12
igor_vitrenko [27]

Answer:

You will have to change this equation into slope intercept form which will be y=2x-4.

Step-by-step explanation:

To change this equation into slope-intercept form, you have to move the x. Do that by minus 6x on both sides. Once you move the x value, your equation will look like -3y=-6x+12. Now you have to divide all your three numbers by -3. Therefore your answer should be y=2x-4. Then going from there you will be able to graph this simple equation by going two spots to the right on the x-axis, and moving 4 spaces down in the y- axis.
