<u>Number one rule of multiplication:</u>

<em>Anything times zero always equals zero.</em>

Solve (-6) * 0=0

Solve 8*(-2)=

To solve this, just multiply 8 * 2 and then make the answer negative:

8*2=16\\8*(-2)=(-16)

Solve 9*(-4) =

Use the same strategy you used above to solve this equation:

9*4=36

9*(-4)=(-36)

Hope this helps!

Explanation:
HI, so it’s very simple if you read this it will be really easy for you in the future! So basically, looking at it, it’s basically multiplying but what confuses you are the signs (-)(negative) and (+)(positive). All you have to know is:
Positive number x positive number = positive answer
Negative number x negative number= positive answer
Positive number x negative number= negative answer
Negative number x positive number= negative answer
And as long as you know this it will be really easy for you. So just multiply as usual normally and then according to the rules find out if the answer will be negative or positive.
Look at the following picture to understand the rules more clearly>>

A right triangle has side lengths a, b, and c as shown below.
Musya8 [376]

Answer:

\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}

Step-by-step explanation:

Given that

A right triangle has side lengths a, b, and c

Because you did not attached photo of the right triangle so I will assume that:

  • Side a is the adjacent (A)
  • Side b is the opposite (O)
  • Side c is the hypotenuse (H)

(Please have a look at the attached photo)

To solve for the trigonometric functions of x, we need to recall the ratios they represent as shown below.

\sin x = \frac{O}{H}\\\cos x = \frac{A}{H}\\\tan x = \frac{O}{A}

EX: the sine of x is equal to the side opposite of angle x over the hypotenuse. Hence, we have the expressions of the trigonometric functions as shown below:

\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}

Hope it will find you well

Plz help! Don’t understand this question
solniwko [45]

Answer:

11.91

Step-by-step explanation:

The question says there is a new line that connects V and T. If this line is drawn, the diagram would have a right-angle triangle. This triangle is called TUV.

In triangle TUV, the side length created by the points VT is the hypotenuse.

For right-angle triangles, you can use the Pythagorean theorem to find any side.

It's in the format side² + side² = hypotenuse².

To use the formula, you need to know the length of the other two sides. The length of these sides, because they are exactly horizontal or vertical, is found by subtracting the smaller coordinate from the other (that is not the same).

The lengths of other sides:

VU:

-3 is the same. The length is 3.5 - (-5.75) = 9.25

UT:

-5.75 is the same. The length is 4.5 - (-3) = 7.5

Substitute the lengths into the Pythagorean theorem:

a² + b² = c²

9.25² + 7.5² = c²  Simplify

141.8125 = c²  Find the square root of both sides to isolate c

c = 11.91  Final answer, length of VT
