First find the slope, (y2-y1)/(x2-x1)=(20-10)/(40-20)=10/20=1/2
y=mx+b, where m is the slope and b is the y-intercept
y=x/2+b, using any point we can solve for b, I'll use (20, 10)
10=20/2+b
10=10+b
0=b, so the cost function is:
C(m)=m/2 (cost in dollars as a function of minutes is minutes divided by two)

Answer:
12.808 meter is the length should Rickey use for the mural.
Step-by-step explanation:
Area of the mural = A = 
Length of the mural = l
Width of the mural = w
l = 5 + 2w
Area of the rectangle = l × w
Solving above equation with the help of Completing squares method:
w = 3.904 m (accept)
w = -6.404 m (reject)
l = (5 + 2w)m = 5 + 2 × (3.904) m= 12.808 m
12.808 meter is the length should Rickey use for the mural.
Answer:
perimeter = 2*a = 2*54 mm = 108 mm
Step-by-step explanation:
For any geometrical figure, the perimeter is the sum of all his sides.
In a rectangle figure, have four sides, two of them equals: a (upper side), b (lateral side), so the perimeter will be:
perimeter = a+a+b+b = 2*(a+b)
A square is a particular case of rectangle figure, in which: a = b.
So, for a square:
perimeter = 2*(a+a) = 2*(2a) = 4*a
Based on the given situation above about Patrick's savings, I can say that the best option for him in order to keep up with the increase 20 years after would be to utilize a compound interest account. The answer would be option B. Notice that with compound interest account, the amount he gets is around $31,000. Hope this helps.
