You plug the x value into whichever function it applies to. X represents the number of shirts ordered. So for example, the first question asks the total cost if you order 57 shirts. Look at the piecewise function. If says is x>50 (or equal), you use the equation 14x + 20. 57 is greater than 50 so plug it into the equation. (14)(57) + 20 = 818. You should be able to do the rest now. If you have any more questions, you can ask.
Answer:
If a scatter plot shows a linear association, then there is a line that describes the relationship between the two measured quantities reasonably well. This means that there is a clear pattern in the data, and that the data points tend to follow a straight line when plotted on a graph. This does not necessarily mean that there is a line that passes through all of the plotted data points or that there is a tendency for relatively high values for one measured quantity to be paired with relatively high values for the other measured quantity.
Step-by-step explanation:
Answer:
y = 40
x = 70
Step-by-step explanation:
y = tan39° × 57
y = 46,16
y = 40
x= 57/ cos39°
x= 73,35
x =70
$2(x) +$8.50 so that is the correct answer.
The answer is : f= -0.14467690+k\1888
