Answer:
(4, -8)
Step-by-step explanation:
The components of a vector are found by subtracting the tail from the head.
__
Head - Tail = (1, -6) -(-3, 2) = (1 -(-3), -6 -2) = (4, -8)
⇒ The component form is (4, -8), or maybe 4<em>i</em> -8<em>j</em>.
_____
<em>Additional comment</em>
There are many ways that the components of vectors can be described. The particular format you are expected to use will likely be found in your curriculum materials.
Answer:
35
Step-by-step explanation:
210/10=21 pens per friend
21+27=48 pens for benjamin
48-13=35 pens left
benjamin has 35 pens now
The correct answer would be 3.
1+(-1)-(-3)
1+(-1)=0
0-(-3)
0+3= 3
Answer:
756π cm^3.
Step-by-step explanation:
Volume of the cone
270π = 1/3 π r^2 h
270π = 1/3 π r^2 * 10
r^2 = 270 / ( 10/3 )
r^2 = 81
r = 9 cm.
So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3
= 486π cm^3.
So the volume of the whole solid = 270π + 486π
= 756 π cm^3.
Answer:
201.06ft^2
Step-by-step explanation:
The formula for the area of a circle is pi*r^2
We just plug in 8 for r and we get our answer.
