The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
Answer:
4080
Step-by-step explanation:
There are 60 minutes in an hour, so you just need to multiply 68 by 60 and you get 4080
As seen from the graph the y intercept is (0,10)
so if we plug 0 as x in the equation we must get 10 as y
in first equation
y=10 * 4^x
if we plug x as 0 , we get y as 10
So first equation is the correct answer
Multiply each number by 10. The constant of proportionality is 10. You can do it!!
