Answer:
y we use y
Step-by-step explanation:
Answer:
6π
Step-by-step explanation:
The period indicates after which time the sine wave repeats.
You divide 2π by the factor in front of your function variable. This is 1/3 for your function.
So 2π/(1/3) = 6π
Answer:
Step-by-step explanation:
Let "s" be the the speed of the car taking the shorter route in
,
Let "s-2" the speed of the cat taking the longer route in
,
Let "d" be the distance of the shorter route in miles and "d+43" be the distance of the longer route in miles.
Now, Equation for car taking the shorter route is given as:
(1)
and Equation for car taking the longer route is given as:
(2)
Now, substitute equation (1) in (2), we get

⇒
⇒
Therefore, equation (1) becomes,

Thus, the shorter route is =275 miles and the longer route is =d+43=275+43= 318 miles.
Multiplying a vector
by a constant
gives you a new vector whose components are the same as
, but scaled by
:

So we have


Vector addition is just a matter of adding the corresponding components together:

Then


denotes the norm/magnitude of the vector
:

We have


56 miles : 1 hour
/2. /2
28 miles : 30 minutes
56+28. 1h+30m
84 miles : 1 hour 30 minutes
84 is the answer
