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:
25
Step-by-step explanation:
To calculate rate, divide the number of cans by the time to get "Cans per minute".
300/15min = 20/min
Let m represent minutes and c for cans.
We write an equation for the problem:
c = 20m
We want to know the time for 500 cans, so substitute 500 for c.
500 = 20m
Isolate m and solve:
m = 500/20
m = 25
It will take 25 minutes to put 500 labels.
X = 0 or x = -1
You can solve this by using the second equation, which is already solved for y and subbing that in for y in the first equation.
14x + (3x^2 - 11x - 4) = -4
14x + 3x^2 - 11x = 0
3x^2 + 3x = 0
Then you can solve by pulling out the greatest common factor
3x(x + 1) = 0
Then set each part equal to 0
3x = 0
x = 0
x + 1 = 0
x = -1
