Write the component forms of vectors u and v, shown in the graph, and find v − 2u.
Answers (I solved it on my own look in comments):
U=
V=
V-2U=
Answers
Step-by-step explanation:
Vector u has a run of -2 and a rise of -2.
u = <-2, -2>
Vector v has a run of 0 and a rise of -4.
v = <0, -4>
Therefore:
v − 2u
<0, -4> − 2 <-2, -2>
<0, -4> + <4, 4>
<4, 0>

in the figure, △ABC is similar to △DEF. what is m∠1
Answers
Answer:
C. 139°
Step-by-step explanation:
Given:
m<A = 62°
m<B = 77°
Required:
Find m<1
Solution:
Since ∆ABC is similar to ∆DEF, therefore:
<A ≅ <D, which means m<D = 62°
<B ≅ <E, which means m<E = 77°
<C ≅ <F
Therefore, based on exterior angle theorem:
m<1 = m<D + m<E
m<1 = 62° + 77° (substitution)
m<1 = 139°

Answer:
6
Step-by-step explanation:
The way you wrote it, it is already rounded.....
The value I remember for pi is 3.14159. This is rounded to the nearest 10-thousandth. Another way of saying the same thing is that it is "rounded to 5 decimal places".
pi--rounded off in decreasing precision:
3.14159
3.1416
3.142
3.14
3.1
3
Watch out for a trap in rounding:
Suppose I start with 5.49. To the nearest 10th, it would be 5.5. To the nearest whole digit, it is 5, not 6. If the original number were 5.51, then rounded to the nearest whole digit would be 6.

y=-4x+5 or -8/2x+5
Step-by-step explanation:
rise over run, to get the slope. when you do this you get rise is 8 because you count from one point to the other on the y axis and get 13-5=8. Then run is 2 do the same but for the x-axis and get 2-0=2. so you end up with 8/2 or 4 and since the line is going downwards its negative. The y intercept is 5 because that's where it intersects the y-axis. and the 5 is positive because it is a positive y, where the point of intersection is

The measure of base angle of the isosceles right angle triangle is 45°.
What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.
Given that,
Triangle ABC is an isosceles right angle triangle.
In an isosceles triangle, two sides are equal and corresponding angles are equal.
Let the corresponding angles are α and α.
Since, one angle of right angle isosceles triangle is 90°.
Also, the sum of angles of triangle is 180°
Implies that,
α + α + 90 = 180
2α = 180 - 90
2α = 90
α = 45
The required value of angle α is 45°
