Dy/dx=(139-196)=(82-139)=(25-82)=constant=-57
So this is just a line with a slope of -57, and we can see that the y-intercept (the value of y when x=0) is 25, thus the line is:
y=-57x+25
Answer: 0.123456
Step-by-step explanation:
The restaurant would have to give the free samples to its customers so that they would provide a feedback for the business.
<h3>What is feedback?</h3>
This is the word that is used to refer to the information that one has to create or give as way of reacting to the use of a product or of a new service.
This is a way of bringing about improvements or about bringing a new line into a new market. The customers in this case would have to tell the restaurant what they think about the new dish.

Step-by-step explanation:
So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.
So we set up the equation
cos θ = adj/hype
cos θ = 5/8
θ =
θ=51.3178125...
θ=51°
