A state park charges $5 per car plus $1 per person as an admission fee. The total charged for a car with x people is f(x) = x +

Studentka2010 [4]

Answer:

Given: f(x) = x + 5

If this function changes to $8 per car then

The function: f(x) = x + 8

The concept of equation of straight line: y= mx + b

where b represents the y-intercept

In the equation above, the y-intercept changed from 5 to 8.

Only the circled ones

M must be (0,0) since it coincides with the origin
R must be (a+b, √(a²-b²)).
The x-coordinate is b from A translated to the right by a.
The y-coordinate is the same as A.

(I think the square root is there to confuse you).

R(0,0)
C(a,b) (same x as T, same Y as E)

Not sure how to prove that.

Answer:

The central angle for the cheese sector would be 108 degrees.

Step-by-step explanation:

We know that a pi chart takes the form of a circle so the total angle measure is 360 degrees.

Now we want to find out what ratio of the pie chart that cheese takes up and apply it to the total degree measure.

30 of 100 students voted for cheese:

so the ratio would be 30/100 or 3/10

Now apply that to the total angle measure:
