Answer:
15i and 4i
Step-by-step explanation:
i is an imaginary number also shown as
.
Since we have 
, thats 15* . Substitute for i and we get 15*i or 15i.
We do the same for 
. This is 4* or 4*i or 4i.
An easy way to do this is to take the negative inside the square root like 
, take the absolute value -6 absolute value=6 and times it by i. So now it becomes 6i
2t + 8 ≥ -4t - 4
2t+4t ≥ -8-4
6t ≥-12
t ≥ -12/6
t ≥ -2
We would be talking about velocity.
Scalar refers to a speed, but not a given direction.
For me, the easiest way to distinguish a scalar from velocity is to think about the mechanism of scales. A scale can go up and down, left and right, but it doesn't give a specific direction. In a Cartesian plane, the scale of (-4, 0) has the same scale as (4, 0) from the origin at (0, 0) because scale doesn't define a specific directional change in the same way magnitude doesn't have a specific direction.
Velocity, on the other hand, requires a direction because it is defined as the rate of change of an object from its initial position to its final position. In this instance, a direction is required as we need to define an object's acceleration or deceleration.
Answer:
1/6
Step-by-step explanation:
There are 6 possible outcomes when you roll a die
1,2,3,4,5,6
P(5) = number of outcomes with a 5/ total outcomes
=1/6
