Step-by-step explanation:
i just did the assignment and got it right
Answer:
2u + v - 4w = <40 , -4>
6u - 8v = <-78 , 58>
4v - 7w = <101 , -36>
11u + 3w = <-88 , 89>
Step-by-step explanation:
* Lets find the value of each operation to find its resultant vector
# 2u + v - 4w
∵ u = <-5 , 7>
∴ 2u = <-10 , 14>
∵ v = <6 , -2>
∵ w = <-11 , 4>
∴ 4w = <-44 , 16>
∴ 2u + v - 4w = <-10 + 6 - -44 , 14 + -2 - 16>
∴ 2u + v - 4w = <40 , -4>
# 6u - 8v
∵ u = <-5 , 7>
∴ 6u = <-30 , 42>
∵ v = <6 , -2>
∵8v = <48 , -16>
∴ 6u - 8v = <-30 - 48 , 42 - -16>
∴ 6u - 8v = <-78 , 58>
# 4v - 7w
∵ v = <6 , -2>
∴ 4v = <24 , -8>
∵ w = <-11 , 4>
∴ 7w = <-77 , 28>
∴ 4v - 7w = <24 - -77 , -8 - 28>
∴ 4v - 7w = <101 , -36>
# 11u + 3w
∵ u = <-5 , 7>
∴ 11u = <-55 , 77>
∵ w = <-11 , 4>
∴ 3w = <-33 , 12>
∴ 11u + 3w = <-55 + -33 , 77 + 12>
∴ 11u + 3w = <-88 , 89>
<h2>
Radius of a Circle Given Center and Point</h2>
To find the radius of a circle when we're given the coordinates of its center and a point it contains, we can use the following formula for distance:
is one point and 
is another
<h2>Solving the Question</h2>
We're given:
- Center: (-2,1)
- Point: (2,-1)
Plug these given points into the formula for distance:
<h2>Answer</h2>
Therefore, the radius of the circle is 
units, or approximately 4.47 units.
Answer:
34
Step-by-step explanation:
8+8=16
9+9=18
16+18=34
Volume = l x w x h
Volume = 1x1x1/4
Volume = 1/4 cm^3
