Answer:

2

Step-by-step explanation:

Given

< x₁, y₁ > and < x₂, y₂ > , then

the dot product is calculated as

x₁ x₂ + y₁ y₂

Given u = < 7, 4 > and v = < 2, - 3 > , then

u • v

= (7 × 2 ) + (4 × - 3 )

= 14 + (- 12)

= 14 - 12

= 2

Solving linear systems of substitution
never [62]
Example: 2x+2y=8 and 3y+2x=6
Okay so u first want to put on of the equations into a y= form. So let's use 3y+2x=6. Subtract 2x from both sides. 3y=6-2x divide by 3. Y= 6-2/3x or y= -2/3x + 6. Now just plug this new equation in for Y since "y=" into the other equation.
2x + 2(-2/3x + 6) = 8.
Then you would distribute the 2 into the parenthesis and simplify to solve for x.
After you solve for x, plug x into one of the original equations to find y.

Will mark Brainlest help me to multiply it step by step without using calculator​
Fynjy0 [20]

Answer:

\displaystyle\theta =   {30}^{ \circ}

Step-by-step explanation:

we would like to solve the following equation:

\displaystyle\sin( \theta)  =  \frac{5}{10}

notice that, the fraction can be reduced therefore reduce fraction:

\displaystyle\sin( \theta)  =  \frac{ \cancel{5 \: }}{ \cancel{1 0} _{2} }

\displaystyle\sin( \theta)  =  \frac{1}{2}

by trigonometric value table we obtain:

\displaystyle\sin( \theta)  =   \sin( {30}^{ \circ} )

get rid of sin:

\displaystyle\theta =   {30}^{ \circ}

and we are done!
