The answer:
first of all, we should know that the expression of a vector V (a, b) can be written as follow:
V = r (Vx i + Vyj), where r is the length of the vector, it is r = sqrt(V²x + V²y)
Vx is the component lying on the x-axis and Vy on the y-axis
<span>v ⃗ lies in Quadrant II, means Vx is less than 0 (negative)
</span>
so Vx= -r sin30° and Vy= rcos30°
r= <span>‖v ⃗ ‖=4√3
</span>
so we have v = - 4√3sin30° i + 4√3 cos30° j
the components are
v(- 4√3sin30°, 4√3 cos30°) = (-2√3, 4√3 cos30°)
Answer:
5/2y - 8
Step-by-step explanation:
Step 1: Add -7 to both sides.
2x+7+−7=5y−9+−72x=5y−16
Step 2: Divide both sides by 2.
2x2=5y−162x=52y−8
Answer:
8,3*0,25=2,10%(2d.p)
Step-by-step explanation:
The total amounts of money which Mrs. Reynolds now has according to the descriptions in the task content is; $68.
<h3>How much does Mrs. Reynolds have now?</h3>
It follows from the task content that;
- Together 105 and m are equal to 153.
- 20 and m is equal to s.
On this note;
Hence, it follows that the amount of money, s she has now is;
