Answer:

Step-by-step explanation:
The magnitude of a vector
is
, which essentially describes the length of the vector itself between the initial and terminal points:

Its 500
because anything that is getting multiplied by one is the same number.
Answer:
y =
or -3.571
x =
or 1.429
Step-by-step explanation:
x - y = 5
x = 5 + y
Solve for y:
y = -6x + 5
y = -6(5 + y) + 5 Substitute x with 5 + y
y = -6(5) - 6y + 5
y = -30 - 6y + 5
y + 6y = -30 + 5
7y = -25
y =
or -3.571
Solve for x:
x = 5 + y
x = 5 + -25/7
x =
or 1.429
Answer:
Increase of 2°F/h..... Option 4.
Step-by-step explanation:
Here in the table time in hours is the independent variable (x) and temperature in °F is the dependent variable (y).
The initial temperature at x = 0 hour is 52°F and then the temperature increases by 2°F per one hour time spent.
Therefore, the temperature is increasing at a constant rate of 2°F per hour from an initial value of 52°F.
Hence, option 4 is correct.
