N! = n*(n-1)* (n-2)* ...... right down to 1

For example 5! = 5*4*3*2*1

it means to multiply all the numbers below n together

example 5! would be 5*4*3*2*1 = 120

Write a equation in standard form that represents the points (1, -4) and (3,-5) Answer for

serious [3.7K]

Answer:

Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.

9x+3y = 36

3y= - 9x + 36

y = -3x + 12

The slope, m = -3

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

The slope of lines parallel is the same.

The slope of lines perpendicular is the negative inverse, m = +1/3

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

Use y = mx + b and the point (1,2) to find b.

2 = (1/3)*1 + b

b = 5/3

The equation is y = (1/3)x + 5/3 (slope-intercept form)

x - 3y = -5 (standard form)

If angle A =90 degree , b=1 cm and a =2 cm then solve the following right angled triangle ABC

Kruka [31]

Answer:

Angle A = 90 degrees, side a = 2.
Angle B = 30 degrees, side b = 1.
Angle C = 60 degrees, side c = $\sqrt{3}$ .

Side c:

If angle A is 90 degrees, side a is the hypotenuse.
$c^{2} + b^{2} = a^{2}$ <--- <em>this is NOT the correct way to write the Pythagorean theorem. I changed it to fit the side lengths. Normally, it is </em> $a^{2} + b^{2} = c^{2}$ <em>, where c is the hypotenuse. Since a is the hypotenuse, I switched the variables.</em>
$c^{2} + (1)^{2} = (2)^{2}$
$c^{2} + 1 = 4$
$c^{2} = 3$
$c = \sqrt{3}$

Finding the angles:

<em>In a 30-60-90 right triangle, the...</em>
<em>Shortest leg = x</em>
<em>Longest leg = </em> $x\sqrt{3}$ <em> </em>
<em>Hypotenuse = 2x </em>
In this case, the shortest leg is 1, the longer leg is $\sqrt{3}$ (or $1*\sqrt{3}$ ), and the hypotenuse is 2 (or $2*1$ ).
As a result, this is a 30-60-90 triangle -- angle B is 30 degrees while angle C is 60 degrees.

Part A: What is the s-intercept, and what does it represent in this situation? What is the t-intercept, and what does it represe

dusya [7]

Part A: The s-intercept is (0,6). The s-intercept represents the amount of shirts sold in the hundreds. There t-intercept in this problem. And Since there is no t-intercept, t represents the year of 2000

Part B: How the graph reacts is as it starts, it starts out as a steady, strait line. Then when it hits (-4,5) it start to incline slightly. What it means is it is doing really well.

Part C: The average rate of change is 0.333333 over a distance of 6.32456.

Part D: The graphs would differ greatly, because f(t) inclines slowly where g(t) would be way steeper and be vertical way before f(t)

What is the midpoint of the segment shown below? (5,4) (5,-3)

Monica [59]

The midpoint is (5, ¹/₂).

<h3>Further explanation</h3>

The midpoint is the coordinates of a point right in the middle of a line segment or two endpoints.

The Midpoint Formula $\boxed{\boxed{ \ M = \bigg( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \bigg) \ }}$

So, abscissa and ordinate of the midpoint are the averages of both endpoints. i.e., (x₁, y₁) and (x₂, y₂).

Given (x₁, y₁) = (5, 4) and (x₂, y₂) = (5, -3).

Let's calculate the midpoint.

$\boxed{ \ M = \bigg( \frac{5 + 5}{2}, \frac{4 + (-3)}{2} \bigg) \ }$

$\boxed{ \ M = \bigg( \frac{10}{2}, \frac{1}{2} \bigg) \ }$

$\boxed{ \ M = \bigg( 5, \frac{1}{2} \bigg) \ }$

We get the midpoint between the two endpoints, that is, (5, ¹ / ₂).
