Answer:

The range is 17

Step-by-step explanation:

First order the data from least to greatest.

25, 14, 9, 20, 16, 8, 12, 8

                 ↓

8, 8, 9, 12, 14, 16, 20, 25

Now the range R is defined as the difference between the highest and the lowest value of the data set:

Once the data is ordered from least to greatest, it can be clearly seen that the highest value is 25 and the lowest value is 8. Then the R is: R=25-8

R=17

A chess player moves a knight from the location (3,2) to (5,1) on a chessboard. if the bottom-left square is labeled (1,1), the
lora16 [44]

The translation mode are-

  • On a chessboard, moving a knight from (3, 2) to (5, 1) results in a translation of 2 squares up and 1 square left.
  • The translation produced is 2 squares right, 1 square up, if a player advances his knight from (5, 1) to (6, 3).
<h3>What is translation?</h3>

In mathematics, a translation is the up, down, left, or right movement of a shape.

Some key features regarding translation are-

  • Because the translated shapes appear to be identical in size as the original ones, they are consistent with one another.
  • Just one or maybe more directions have been altered.
  • There has been no change in its form because it is simply being moved from one location to another.
  • The object may initially travel left, then turn right, and so on.
  • The direction or the course of this shift in the object's position can also alter.
  • Each point on the shape will move by the same number of units during translation.
  • For instance, all of the points will move two units to that same right if one point moves two units to that same right.

Dividing whole numbers 22 divided by 300
dezoksy [38]

Answer:

22 divided by 300 will be equal to 0.07333.

Step-by-step explanation:

Dividing 22 by 300

\frac{22}{300}=\frac{2\times 11}{2\times 2\times 5\times 5\times 3}

\frac{22}{300}=\frac{11}{2\times 5\times 5\times 3}=\frac{11}{150}

\frac{11}{150}=\frac{11}{15}\times \frac{1}{10}

The value of \frac{11}{15}=0.7333

\frac{22}{300}=\frac{11}{150}=0.7333\times \frac{1}{10}=0.07333

So, the value of 22 divided by 300 will be equal to 0.07333.

Answer:

See below for answers and explanations (along with a graph)

Step-by-step explanation:

<u>Part A</u>

Set f(x)=0 and factor the expression by grouping:

f(x)=2x^2-3x-5\\\\0=2x^2-3x-5\\\\0=2x^2+2x-5x-5\\\\0=2x(x+1)-5(x+1)\\\\0=(2x-5)(x+1)

Use the Zero Product Property to find the x-intercepts:

0=2x-5\\5=2x\\x=\frac{5}{2}

0=x+1\\x=-1

Hence, the x-intercepts for the graph of f(x) are x=-1 and x=\frac{5}{2}.

<u>Part B</u>

Find the x-coordinate of the vertex:

x=-\frac{b}{2a}\\ \\x=-\frac{(-3)}{2(2)}\\\\x=\frac{3}{4}

Find the y-coordinate of the vertex:

f(\frac{3}{4})=2(\frac{3}{4})^2-3(\frac{3}{4})-5=-\frac{49}{8}

Hence, the vertex is (\frac{3}{4},-\frac{49}{8}). We can see from the positive leading coefficient of the function that the vertex will be a minimum because the parabola will open faced-up.

<u>Part C</u>

You can use the x-intercepts and vertex to plot points of the graph of the function. Additionally, you can throw in the y-intercept in as well. The y-intercept, in this case, is f(0)=2(0)^2-3(0)-5=-5, or (0,-5) as an ordered pair. See attached graph.
