Your answer would be 0.2x + 7.5
Answer:
Step-by-step explanation:
Suppose x and y are nonzero vectors in an inner product space.
Let us assume that x and y are orthogonal
i.e. innter product is 0.
This implies dot product of x and y is 0
Then x.y =0
i.e.
Proved
Converse part:
Let
Square also would be equal
Hence inner product of x and y is 0
The answer is B, 7i.
sqrt(-49)
Pull out an i.
i*sqrt(49)
Take the square root to get 7i.

Answer:
x=95
Step-by-step explanation:
Angles on a line add to 180. Therefore, finding
180=85+x
Will result in the correct answer. Also, solving
180=35+2x
for x will get you 95.
