Step-by-step explanation:

Math Formulas

Math formulas are expressions that have been created after several decades of research that help to solve questions quickly. It is easy to perform simple arithmetic calculations such as addition, subtraction, and so on. However, when it comes to algebraic expressions, geometry, and other topics you need mathematical formulas to simplify the process of reaching the answer and saving time in the process. At Cuemath you will not only find formulas for every topic but will also get an idea of how that equation was developed. Thus, you will not have to memorize formulas, as you understand the concept behind them.

Use these formulas to solve problems creatively and you will automatically see an improvement in your mathematical skills. Given below is the list of formulas alphabetically arranged for your convenience. Hence, you can easily find formulas that need to be revised or require to be referenced.

The links to the list of math formulas available on different topics have been arranged alphabetically for your convenience. So pick a topic and start learning!

Sin(20)=x/670 ????????
mash [69]

Answer:

229.2

Step-by-step explanation:

Remark

There's a lot in this question. The x is not just any x. It is defined and limited by its relationship with the sine function.

The Sin is defined as Opposite over Hypotenuse in a right triangle. The 670 is the Hypotenuse. You know that by the definition of Sine.

So one thing you should always keep in mind: the x because of where it is in the definition, will always be smaller than the Hypotenuse. So you should get a value less than 670.

Formula

Just as you have it

Sin(20) = x / 670

Solution

Multiply both sides by 570

670 * sin(20) = x

sin(20) = 0.3420

x = 670 * 0.3420

x = 229.2

Given the function f(x) = -2x2 + 4x - 7, find f(-4).<br> -55<br> -7<br> 25
Neko [114]

Answer:

f(-4)= -55

Step-by-step explanation:

We want to find f(x), or y, when x is equal to -4.

Therefore, we can substitute -4 in for x in the function.

f(x) = -2x^2 + 4x - 7

Substitute -4 in for x

f(-4) = -2(-4^2) + 4(-4) - 7

Evaluate the exponent

f(-4)=-2(16)+4(-4)-7

Multiply -2 and 16

f(-4)= -32+4(-4)-7

Multiply 4 and -4

f(-4)=-32-16-7

Subtract

f(-4)=-55
