A to D - 2 letters in between
D to I - 4 letters in between
I to P - 6 letters in between
P to Y - 8 letters in between
the answer should be Y.
hope this helps :)
Answer:
A
Step-by-step explanation:
Given
u = <6, -1>
u = 6i-j
and
v=<7,-4>
v=7i-4j
The formula for angle is:
Let x be the angle
where ||u|| is the length and u.v is the dot product or scalar product of both vectors
So,
The calculated angle will be in radians. To find the angle in degrees:
Hence Option A is correct ..
X=1, because they both have the same height (y), so they'll cross each other!
Answer:(4,1)
Step-by-step explanation:
Given that (p - 1/p) = 4, the value of p² + 1/p² is 18. Detail below
<h3>Data obtained from the questio</h3>
- (p - 1/p) = 4
- p² + 1/p² = ?
<h3>How to determine the value of p² + 1/p²</h3>
(p - 1/p) = 4
Square both sides
(p - 1/p)² = (4)²
(p - 1/p)² = 16 ....(1)
Recall
(a - b)² = a² + b² - 2ab
Thus,
(p - 1/p)² = p² + 1/p² - (2 × p × 1/p)
(p - 1/p)² = p² + 1/p² - 2
From equation (1) above,
(p - 1/p)² = 16
Therefore,
p² + 1/p² - 2 = 16
Rearrange
p² + 1/p² = 16 + 2
p² + 1/p² = 18
Thus, the value of p² + 1/p² is 18
