50 POINTS! Plot function h on the graph.<br><br> NO LINKS
tangare [24]

See attachment for the graph of the piecewise function h(x)

<h3>How to plot the function?</h3>

The function is given as:

h(x) = | -4,    x < 3

         | x + 5,    x >= 3

The above function is a piecewise function.

It has 2 separate functions at two domains

This means that we plot the sub-functions in the piecewise function at their respective domain

See attachment for the graph of the piecewise function h(x)

Joe has a bag of marbles. There are 2 purple, 1 red, and 3 green marbles in the bag. Joe selects a marble, does not replace it b
STALIN [3.7K]

Answer:

1/10

Step-by-step explanation:

There are 6 marbles in the bag. 3 out of 6 are green.

3/6 = 1/2

So, he has a 1/2 of picking a green marble.

After getting a green marble, Joe doesn’t replace it meaning there are now only 5 marbles in the bag.

Since there’s one red marble in the bag the chance of trying one is 1/5.

Now to find the chance or drawing a green and red marble you need to do the equation:

1/2 x 1/5

This equals 1/10.

The probability is 1/10

A right pyramid with a square base has a base edge length of 24 feet and a slant height of 20 feet.
4vir4ik [10]

Answer:

10.583

Step-by-step explanation:

If the height = h

Distance between the slant edge to center is 24 Cos 45

Therefore

h^{2}  = 20^{2}  - (24 Cos 45)^{2}

h = \sqrt{400-288} = 10.583
