Answer:
Common difference is 55
Step-by-step explanation:
C(m)=55m
Substitute m=1 to find the distance traveled by Mia in one hour
55m= 55(1)
= 55
Distance traveled in one hour is 55 miles. Substitute m=2 to find the distance traveled by Mia in 2 hours
55m=55(2)
= 110
Distance traveled in 2 hours is 110 miles. Substitute m=3 to find the distance traveled by Mia in 3 hours
55m=55(3)
= 165
Distance traveled in 3 hours is 165 miles. Substitute m=4 to find the distance traveled by Mia in 4 hours
55m=55(4)
= 220
Distance traveled in 4 hours is 220 miles. Then the common difference is
d=110-55=165-110=220-165=55
Answer: the widget would be sold for $84.3
Step-by-step explanation:
The amount of profit, y made by the company, is related to the selling price of each widget, x, by the given equation which is expressed as
y = - x² + 77x - 615
At the point of breaking even, profit = 0. This means that
- x² + 77x - 615 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = - 1
b = 77
c = - 615
Therefore,
x = [- 77 ± √(77² - 4 × - 1 × - 615)]/2 × + 1
x = [- 77 ± √(8389)]/- 2
x = (- 77 + 91.59)/2 or x = (- 77 - 91.59)/- 2
x = - 7.295 or x = 84.3
Since the price cannot be negative, then x = $84.3
70 bc the distance from b and c is 14 then multiply that by five cause that is the distance between c and d
Answer:
12
Step-by-step explanation:
6x2=12 (do the parentheses first) and 12 times 1 is 12
