a. As described in the problem you will be paying in the bill $0.15 per minute which means you have a linear relationship where both the total cost of the bill and the minutes will grow at the same rate (the price of the minute times the minutes) like this
where C(t) is the total cost of the cell phone bill and t will be the time in minutes
b. The domain of the function will be the values that we can enter to the function. It is defined in the problem that this cost of the minutes its only up to 600 minutes so there is our limitation for the values that will enter the function. The domain will be between 0 and 600 both included because if he calls 0 minutes the bill will be 0 and if he calls 600 he would pay 0.15 for this last minute as well.
Answer:
area of a square is S^2
s = 5n^4
area = (5n^4)^2 = 25n^8
Step-by-step explanation:
6i + 4j written in component form is < 6, 4 >.
If we factor a 2 out of each component we get this,
2 < 3, 2 >
This now represents a scalar times the vector < 3, 2 >.
Let's just give it a different scalar value to find a vector in the same direction.
1 < 3, 2 > = 3i + 2j
3 < 3, 2 > = 9i + 6j
4 < 3, 2 > = 12i + 8j
So there are some other vectors going in the same direction as 6i + 4j but with different magnitudes. We can see that 3i + 2j is one of our options, ya?
