Answer:
1464
Step-by-step explanation:
(110-85)/2 * (85+110)/2 + (((110-85)/2)^2*pi)/2 using Calculus lvl 5.6
thus getting 1464 rounded
A) A straight line.
This is so because the equation is of the first degree (the largest power of x is one). Thus making it a linear equation. The gradient in the equation here (3/4) shows that when you increase the value of x by 1, they value for y increases by 3/4. Since the increments are constant, you will see that the function is a straight line if you draw it.
Answer:
Mixed Number Form:
-1 3/7
Step-by-step explanation:
Y = base pay + (variable pay * x)
37.50 = base pay + (variable pay * 5)
75 = base pay + (variable pay * 20)
let v be the variable pay:
base pay = y - variable pay * x
37.50 - 5v = 75 - 20v
-5v + 20v = 75 - 37.50
15v = 37.50
v = 37.50/15
v = 2.5
37.50 - 5(2.5) = 75 - 20(2.5)
37.50 - 12.50 = 75 - 50
25 = 25
base pay is 25 ; variable pay is 2.50 per newspaper delivered.
y = 25 + 2.50x
