(x - y)^2 + 4z(x - y) +3z^2 (and btw ^2 means squared and this is going for 10 points)

Answers

Answer 1

Answer:
(x - y)² = x² + y² - 2xy

4z(x - y) = 4zx - 4zy

3z² = 3z²

Addum all up:

x² + y² - 2xy + 4zx - 4zy + 3z²

(To me, it was a lot simpler before I simplified it.)

Find the unit rate for number of parts manufactured per hour if 1630 parts are made in 6 hours. Round to the nearest integer.291 parts/h
237 parts/h
325 parts/h
272 parts/h

Answers

Unit rate is defined as the amount of work done per unit time. In this case, the "work" refers to the amount of parts made. Unit time is then measured in hours. Since the given problem states the total number of parts manufactured and the total time of manufacturing, we simply have to divide the number of parts by the manufacturing time to obtain the unit rate. This is done as follows:

Unit rate = total number of parts manufactured / total manufacturing time
Unit rate = 1630 parts / 6 hours
Unit rate = 271.667 parts/h

Therefore the unit rate is approximately 272 parts/h.

Answer:

Your answer is 272 parts/h.

Step 1: Subtract 5 from both sides.
−8w+5−5=−43−5
-8w=-48

Step 2: Divide both sides by -8.
-8w/-8 = -48/-8

What is the difference between rational and irrational numbers? And we believe whole numbers are 0 and any number after it to the positive side. What are the negative numbers called, just integers? We are also a little confused about the difference in counting numbers and whole numbers, are they the same?

Answers

Definition:
Every rational number can be written as a fraction with whole numbers
on top and bottom. Irrational numbers can't.

Working method of recognizing them:
Any number that you can write down completely, on paper, using number digits without any symbols, is a rational number, whether you write it as a fraction or as a decimal.

Popular misconception:
A rational number doesn't necessarily produce a decimal that ends, and a decimal that never ends is not necessarily an irrational number.
Examples: 1/3, 1/7, 1/9, 1/11 are never-ending in decimal form.

Whole numbers are the positive integers and zero.

Counting numbers are the whole numbers without zero.

Integers are the whole numbers plus their negatives.

3. Determine whether or not AB is tangent to circle O. Show your work.

Answers

The line AB touching the circle at point B in the considered diagram is not tangent to the circle O.

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

$|AC|^2 = |AB|^2 + |BC|^2$

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

How are radius and tangent to a circle related?

There is a theorem in mathematics that:

If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.

So, if AB is a tangent, then ∠ABO = 90° and therefore satisfies Pythagoras theorem.

Assuming AB is tangent, then ABO is right angled we should get:

$H^2 = P^2 + B^2\n30^2 = 16^2 + 12^2\n900 = 256 + 144\n900= 500$

This statement is false, and therefore, so as our assumption is false that ABis tangent to circle O. Thus, AB is not tangent to circle O.

(so it might be that even if AB looks like touching at one point the circle O, but AB might be intersecting the circle at two points, or not touching it at all)

Thus, the line AB touching the circle at point B in the considered diagram is not tangent to the circle O.
