Point A is at (3, -8) and point B is at (7, 3). What is the midpoint of line segment AB?​

Answers

Answer:

[tex](5, -5/2)[/tex]

Step-by-step explanation:

The midpoint of any line segment is the average of the x- and y-values of the two endpoints.

Therefore, the midpoint of [tex]AB[/tex] is [tex]((3+7)/2, (-8+3)/2)=(10/2, -5/2)=(5, -5/2)[/tex].

So, the answer is [tex]\boxed{(5, -5/2)}[/tex] and we're done!

Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is Taylor's reasoning correct?

Answers

Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.

No, Taylor's resoning is incorrect because  2,800,000 = [tex]2.8 * 10^{6}[/tex]

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  [tex]2.8 * 10^{6}[/tex].  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, Taylor's reasoning is incorrect.

What is the slope of this line?

Answers

The slope of horizontal lines is zero because they are straight with no curve.

The slope is calculates using the rise over the run.

Rise= How many units we move up. Here we move 0 units.

Whatever the run is (NOT 0) if we divide 0 by the run, we will get 0.

Diagonal lines always have slope.

A polynomial is a factor of another polynomial if when divided they have a remainder of zero. True or False.

Answers

Answer:

True

Step-by-step explanation:

The Factor theorem states that  for any polynomial f(x) if f(c)=0 then x-c is a factor of the polynomial f(x).

If any polynomial f(x) is divided by x-a and remainder is 0 that means f(a)= 0 .In other words we can say x-a is a factor of the polynomial f(x).So the statement :If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial is True.
