For this case we have the following vector:
v = 2 * (cosine (45) i + sine (45) j)
Rewriting we have:
v = 2 * (cosine (45) i + sine (45) j)
v = 2 * ((0.707107) i + (0.707107) j)
v = (1.414214) i + (1.414214) j
Answer:
the vector of length 2 making an angle of 45 with the x-axis is:
v = (1.414214) i + (1.414214) j
D=vt, distance is equal to velocity times time.
4v+3(v+3)=149 perform indicated multiplication
4v+3v+9=149 combine like terms on left side
7v+9=149 subtract 9 from both sides
7v=140 divide both sides by 7
v=20
So the ship traveled at a speed of 20 mph when heading east.
Answer:
9 batches
Step-by-step explanation:
(Found the full problem online)
1 batch : 4 liters of orange juice and 5 liters of soda water
How do we get from 4 and 5 to 36 and 45? For both we multiply by 9.
4 * 9 = 36
5 * 9 = 45
Therefore, they would be able to make 9 batches.
Hope this helps, please mark brainliest if possible :)
Answer:
32
Step-by-step explanation:
this expression cannot be simplified because there are no like terms to combine with the numbers in the expression.
the number that goes in the ? is 32
