Learn the unit circle to understand better, but basically its just a reformed circle that goes up and down on an  y = ? line on a graph.

Answer:

The answer is B.

Step-by-step explanation:

Recall that lines are one of the three undefined terms in geometry, the other two being points and planes. If I had two, I would describe it as a "one-dimensional figure infinitely pointing in both of its directions", but that definition in itself is hard to grasp.

The good thing about undefined terms, though, are that they're easy to describe. Specifically, lines have two key attributes: the slope and the y-intercept.

Slope is "a number that describes both the direction and the steepness of [a] line". It's denoted by m, and it's usually called "rise over run" because slope is also the relationship between the vertical compoenent y and the horizontal component x.

The y-intercept is "the point where [a] line intercects the y-axis". Plain and simple. It also describes the position of a line, and it is denoted by b.

So, we know what slope and the y-intercept are, but how does this help us solve the problem?

Well, we are provided a graph, so let's make sense of the problem.

A line is defined by the slope and the y-intercept, which is why we always write the equation in slope-intercept form (y = mx + b). But this must mean a line must have a unique m and b as well!

So, let's start with b (the y-intercept). The line intersects the y-axis where the 2 margin is, so I can already say that the y-intercept is (0,2). We already have one piece of the puzzle filled: y = mx + 2. We can already rule out A and D.

Now let's find m. Remember that slope is "rise over run". Also, two points can always form a line. This means that at one point, I can move both vertically and horizontally to the next point of the line and use that to write the slope! So let's do that.

From the y-intercept (0, 2), I can move -1 units up and 5 units right to reach the next point on the line, (5,1). For simplicity's sake, we'll just say that rise is y, run is x, and m = y/x. This means that m = -1/5, which is our slope. We can rule out C.

Therefore, our answer is B.

If you are trying to find the missing measures of a rectangle, you should know that all rectangles have four sides, and each side has a length.

In other words, if you have a rectangle, two of the angles must be 90 degrees, and the other two angles must also be 90 degrees. To find the missing measures of a rectangle, you need to use the properties of rectangles.

First, find the length of each side. The length of all sides of a rectangle should be the same. Then, calculate the area of the rectangle. You can do this by multiplying the length of one side with the length of the other side.

Finally, you can use the Pythagorean Theorem to find the missing measures.

The Pythagorean Theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

Using this theorem, you can find the length of the hypotenuse of the rectangle.

A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.

What theory directly contradicts concept of absolute zero?

All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).

Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.

Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

Radius of the semicircle is 8 km and diameter is 16 km.

What is area of the semicircle?

The area of the semicircle can be determined using the formula,\(A = 1/2 * \pi * r^2\)

The area of a semicircle is given by the formula:

\(A = 1/2 * \pi * r^2\)

where A is the area and r is the radius.

We are given that the area of the semicircle is 32π km². So, we can set up the equation:

\(32\pi = 1/2 * \pi * r^2\)

Simplifying this equation, we get:

r² = (2 × 32π) / π = 64

Taking the square root of both sides, we get:

r = 8 km

So, the radius of the semicircle is 8 km.

The diameter of the semicircle is twice the radius, so:

d = 2r = 2 × 8 km = 16 km

Therefore, the diameter of the semicircle is 16 km.

\( \sf \: 2 \left( 4- \frac{ 1 }{ 3 } u \right) = -u+2\)

Use the distributive property to multiply 2 by \(\sf 4-\frac{1}{3}u\).

\( \sf \: 8+2\left(-\frac{1}{3}\right)u=-u+2 \)

Express \(\sf2\left(-\frac{1}{3}\right)\) as a single fraction.

\( \sf \: 8+\frac{2\left(-1\right)}{3}u=-u+2 \)

Multiply 2 and -1 to get -2.

\( \sf \: 8+\frac{-2}{3}u=-u+2 \)

Add u to both sides.

\( \sf \: 8-\frac{2}{3}u+u=2 \)

Combine \(\sf-\frac{2}{3}u\) and u to get \(\sf\frac{1}{3}u\).

\( \sf \: 8+\frac{1}{3}u=2 \)

Subtract 8 from both sides.

\( \sf\frac{1}{3}u=2-8 \)

Subtract 8 from 2 to get -6.

\( \sf\frac{1}{3}u=-6 \)

Multiply both sides by 3, which is the reciprocal of 1/3.

\( \sf \: u=-6\times 3 \)

Multiply -6 and 3 to get -18.

Answer:

C

Step-by-step explanation:

The absolute value function always gives a positive value, however the expression inside can be positive or negative, that is

0.5x + 1 = 5 ( subtract 1 from both sides )

0.5x = 4 ( divide both sides by 0.5 )

x = 8

OR

- (0.5x + 1) = 5

- 0.5x - 1 = 5 ( add 1 to both sides )

- 0.5x = 6 ( divide both sides by - 0.5 )

x = - 12

There are 2 solutions to the equation

x = 8 or x = - 12

a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)

To divide the polynomial a(x) by b(x), we can use long division as follows:

    3x - 6

-------------------

x² + 2 | 3x² - 4x² + x

- (3x³ + 0x²)

---------------

-4x² + x

- (-4x² - 8)

-------------

8x - 8

Therefore, the quotient is 3x - 6, and the remainder is 8x - 8.

a(x) = b(x) * (3x - 6) + (8x - 8)

   -2 | 3 -4  1  0

      |    -6 20 -42

      |-------------

      | 3 -10 21 -42

The numbers on the bottom row represent the coefficients of the quotient, which are 3, -10, 21. The last number on the bottom row, -42, is the remainder. Therefore, the quotient is:

3x² - 10x + 21

8x - 8

a(x) = b(x) * (3x² - 10x + 21) + (8x - 8)

Answer:  Choice C.   \(f(x) \le 1\)

=========================================================

Reason:

The f(x) represents the y output, and the range is the set of all possible y outputs of a function.

The largest y can get is y = 1, which is at the highest point of the graph, aka the vertex.

We can have y = 1 or y < 1.

Therefore, the range is \(y \le 1\) which translates to \(f(x) \le 1\)

Answer:

p = (2h-W)/-3

Step-by-step explanation:

2h - W = -3p

divide both sides by -3

(2h-W)/-3 = p

The value of p is w/3 - 2h/3.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S

Given:

2h = W-3p

For p move w

2h - w = -3p

Now,  divide both side by 3

2h/3 - w/3 = -3p/3

2h/3 - w/3 = -p

p= w/3 - 2h/3

Hence, the value of p is w/3 - 2h/3.
