Assuming you're wanting a proportion, ? = 18.75 satisfies the proportion.

5*30/8 = 18.75

\({10}^{-3} = \frac{1}{{10}^{3}} = \frac{1}{1000} = 0.001\)

10^-3 = 0.001

Hope this helps.

Slope intercept form is y=mx + b

The objective is to get the  y  variable all by itself.

For example, 2x+4y=12

First you would subtract both sides by 2x, giving

4y=-2x+12 (the original 12 was positive so give it a plus sign)

Then divide both sides by 4 to isolate that y. That would lead to

y=-2x/4 +3

Which simplifies to

y= -x/2 +3

This is one example. But remember, the way to put the equation into slope intercept form is to isolate the y like I've done above!

cotangent (shorthand, cot) is the reciprocal of tangent (shorthand, tan)

\(cot\theta = \frac{1}{tan\theta}\)

1 N is defined by (1kg accelerated 1m/s²)

8 kg accelerated 32m/6s² or 32/16m/s² or 5.333333m/s²

8xs the weight and 5.333333xs the acceleration should require (8 * 5.333333)xs the force.

It should take about 42.666667 Newtons of force.

0° and multiples of 180°

Like this: 0°, 180°, 360°, 540°, 720°, etc.

edit: multiples of 45° also work.

Math itself is a tool for solving problems. A "math problem" (the generalization) is a form of problem which is described by the method associated with solving it. The problem: "I have $100. How many $4 jars of jelly can I buy?", which is represented by 100 = 4x, can be called a math problem. The problem is solved by math, 100 = 4x, then 25 = x, so I can buy 25 jars of jelly.

The other 'math problem' can be something in math which is not explained or fully understood, or proven, or any combination of the 3. For example, a 'math problem' (better called a "problem in math") would be: "How many twin primes are there?" This is a 'problem' because the answer is not yet known. There are believed to be infinitely many, but its not certain to be the case.

Ultimately, math is to be used by you. A math problem is a problem of itself. A math problem is really your problem, which happens to be described by math.

So, the reason a math probelm can't solve itself, is because it is not its own. It's yours. That's why you solve the math problem, because it is your problem.

"of" means multiply

7/17 * 34 = 34*7 /17 = 7*2 = 14

The homepage of this website is a calculator, which is much faster than someone on the forum for something as simple as this.

edit: I left out an equal sign.

Here's one instance of an angle sequence:

-2π, -3π/2, -π, -π/2, 0, π/2, π, 3π/2, 2π

I'll see what I can do.

2 tan 4x -1/2 = -1/2

(+1/2 to both sides)

2 tan 4x =0

(both sides divided by 2)

tan4x = 0/2 = 0

(inverse tan of both sides)

4x = 0

(divide both sides by 4)

x = 0/4 = 0

0 is your answer.

A general answer would be \(0+\frac{nπ}{2}\)

Shades, I really, truly, hope you found this helpful. I'm sorry it took 2+ hours to get to this question, and I hope you haven't given up.
