Find a vector of magnitude 3 in the direction of v=4i-3k

pochemuha

Answer:

$\frac{12i}{5} - \frac{9k}{5}$

Step-by-step explanation:

The magnitude of a vector v = ai + bk is

$|v| = \sqrt{a^{2} + b^{2}$

In this problem, we have that:

Find a vector of magnitude 3 in the direction of v=4i-3k:

The first step is finding the unit vector of v, $v_{u}$ .

$|v| = \sqrt{4^{2} + (-3)^{2}} = 5$

$v_{u} = \frac{4i}{5} - \frac{3k}{5}$

Magnitude 3, same direction.

We multiply the unit vector by +3, since it is in the same direction. If it was in the opposite direction, we would have multiplied by -3.

The answer is:

$\frac{12i}{5} - \frac{9k}{5}$

Find angle X on the given figure. m

Andru [333]

Answer:

x = 32°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary.

∠ A and ∠ D are consecutive angles, then

131 + 17 + x = 180

148 + x = 180 ( subtract 148 from both sides )

x = 32°

The width of Maya’s poster is 2 inches shorter than the length. The graph models the possible area (y) of Maya’s poster determin

sp2606 [1]

Width = Length - 2
Area = L x W
y = x * ( x - 2 )
If the point is ( 2, 0 ): x = 2, y = 0
y = 2 * ( 2 - 2 ) = 2 * 0 = 0 ( area )
Answer:
B ) The area is 0 if the length is 2.
