Answer:
v = 2√2i -2√2j
Step-by-step explanation:
v = ||v||·cos(θ)i +||v||·sin(θ)j
v = 4cos(315°)i +4sin(315°)j . . . . . . fill in the numbers
v = 2√2i -2√2j . . . . . . . . . . . . . . . put in desired form
Answer:
B
Step-by-step explanation:
In an isosceles trapezoid any lower base angle is supplementary to any upper base angle, thus
6x + 2x + 4 = 180, that is
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22 → B
Answer:
x = 8
Step-by-step explanation:
- Write it out:
- Add 5 to each side, so it now looks like this: 3/2x = 12
- Divide each side by 3/2 to cancel out the 3/2 next to x. It should now look like this: x = 8

Answer:
B
Step-by-step explanation:
Our values are:
N = 100,000 (We assume it)
Proportion is p = 0.6
Margin of error (E) = 0.05
confidence-level (cl) = 0.95
Z-value = 1.96
We need to approach through Proportion,

Substituting,
