Answer:
Option b.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
h(t) = cos (t +1)
Please, see attached picture below.
By looking at the picture, we can tell that the amplitude is equal to 1
The function has a period of T = 2π
We can see there is no vertical shift.
It has a phase shift of +1. (Which moves the graph to the left)
Answer:
Option b.
Answer:
a
the displacement of the plane is
b
The displacement of plane from Portland to Akron with layover at Houston is
c
the vector which defines this displacement is
Step-by-step explanation:
From the question we are the
The displacement from Portland, Oregon to Houston, Texas. is
The displacement from Houston, Texas to Akron, Ohio. is a
a
The motion of the plane in question a is in the opposite direction to vector
So the displacement of the plane is
b
The motion of Portland to Houston to Akron is in the direction of both vector and
so
The displacement of plane from Portland to Akron with layover at Houston is
c
From the question we are told that the plane flies over Portland to get to Anchorage, Alaska which implies that it is moving in opposite direction to the vector
Give that distance from Portland to Houston is
and the distance from Portland to Anchorage is km
Then the vector which defines this displacement is mathematically represented as
