Answer:

Step-by-step explanation:
A statement is given i.e. "ten to the eighth divided by ten to the negative third."
It means that 10 to power 8 divided by 10 to the power -3.
Mathematically,

We know that, 
Here, x = 10, a = 8 and b = -3
So,

So, the answer is 
Answer:
The speed of the plane is 
Step-by-step explanation:
The vector (5,6) represents a point in the coordinate system time-position.
So, we have that at t = 5 s the position is x = 6.
Let's recall that the slope of this vector is the speed, then using the tangent definition:

The discount was
15%×$275 = $41.25
so the price at which the system was sold was
$275.00 - 41.25 = $233.75
The sales person receives 2% of this, or
2%×$233.75 ≈ $4.68
