<h3>Answer: Choice A) </h3>

No, the piecewise graph is NOT a function because it does NOT pass the vertical line test.

The vertical line test is where we try to pass a line through more than one point on the curve. If it is not possible to do this, then the graph is said to "pass the vertical line test".

In this case, the given graph fails the vertical line test. Look at something like x = -2. We can draw a vertical line through here to pass through more than one point. One point is on the upside-down V shape, and the other point is on the parabolic shape. Plugging x = -2 into this leads to more than one y outputs.

A function is only possible if any valid x input (from the domain) leads to exactly one output y value (in the range).

The first angle given is not needed. it is extra info.
so to start off you need to see that it is a subtraction problem. it is angle BEF minus angle GEF
90 degrees minus 39 degrees then it is all math.
angle BEG = 51 degrees

14. Find the average of the 1000 whole numbers
steposvetlana [31]

Answer:

500.5

Step-by-step explanation:

The average of a set of numbers is the sum of the numbers divided by the number of numbers.

The sum of all whole number form 1 to n is n(n + 1)/2.

The sum of all whole numbers from 1 to 1000 is

1000(1000 + 1)/2 = 1000(1001)/2 = 500,500

The average is the sum of the numbers divided by the number of numbers.

average = 500,500/1000 = 500.5

A sporting good store is offering an additional 30% off all clearance items and she purchases a pair of running shoes on clearan
Talja [164]

Answer:

Total discount = $39.50

                  or 46.47 %

Step-by-step explanation:

First we need to figure out what she will pay for the shoes.  She is getting 30 percent off the 65 dollars.

Discount = price * percent off

                = 65*.3

                = 19.50

The cost of her shoes is the price minus the discount.

Cost = 65- 19.5

        = 45.50


To find the total discount, take the original price and subtract the final cost.

Total discount = 85-45.50

                        = 39.50

To find the total percent discount, we use the formula

      total percent discount = (original - final)/original * 100

                                             = (85- 45.50)/85 * 100

                                             = 39.5/85*100

                                              = 46.47%

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack
BARSIC [14]

Answer: 4*p=8

Step-by-step explanation:

<em>You can use inverse operation to answer this equation.</em>

  • <em>write out you problem: 4 x p =8</em>
  • <em>The inverse of multiplication is division</em>
  • <em>you do 4/4 which gives you one but the 4 will cancel itself out</em>
  • <em>Do 8/4 which gives you 2</em>
  • <em>under the equation write p = 2</em>
  • <em>And be sure to line the p up with the p, the equal sign with the equal sign, and  the 2  stays where it is ( which should be already lined up with the 8)</em>
