Answer:
You are given a vector in the XY plane that has a magnitude of 87. 0 units and a y component of -66. 0 units. The direction of the vector V is;
<h3>How to know the direction of a vector?</h3>
We know that the formula for 2 vectors like this in the x and y directions is; A = xi^ + yj^
Where A is the magnitude of the resultant
x is the value of the x-component
y is the value of the y-component
We are given;
Magnitude of vector = 84 units
Y-component of the vector = -67 units
Thus,
From A above, let us take the positive value of the x-component and as such our original vector will be;
A = 56.68i^ - 66j^
The direction of the vector V is;
Since it points entirely to the negative x-axis, then the angle is;
180 - (-27.15) = 207.15°

Answer:
12
Step-by-step explanation:
3 divided by .25 equals 12. You move the decimal of 25% twice to the left to get .25.
Answer:
<em>A . 0.85 + (0.15 +(-3)) = -2</em>
<em>B . [(-3)+(-3)]+(-3) = - 9</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Associative property with addition</em>
<em>(a+(b+c)) = (a+b) + c</em>
A)
Given 0.85 + (0.15 +(-3)) = (0.85 +0.15)+(-3)
= 1 - 3
= -2
B) Given [(-3)+(-3)]+(-3) = ( (-3)+[( -3)+(-3))]
= ( -3 +[-3-3]
= -3 -6
= -9
<u><em>Final answer:</em></u>-
<em>A . 0.85 + (0.15 +(-3)) = -2</em>
<em>B . [(-3)+(-3)]+(-3) = - 9</em>
