How do I solve this and what are the rules to solving this

334

(Pemdas rules apply)

Step-by-step explanation:

In order to sole this equation we must use what is called "PEMDAS" which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. This is also known as the order of operations which is the correct sequence of an equation (From left to right).

Now solving the equation itself:

4 [ 2.5 + 3 ( 20 + 7 ) ] <--- First add 20 and 7.

4 [ 2.5 + 3 ( 27 ) ]   <--- Then multiply 27 by 3.

4 [ 2.5 + 81 ]   <--- Then add 81 and 2 together.

4 [ 83.5 ]  <--- Multiply 83.5 by 4.

= 334

Therefore, our final answer is 334, I hope this helps :)

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
