Answer:
DP=9
Step-by-step explanation:
DS=4
DP=5
DP=DS+DP=4+5=9
DP=9
Convert all the numbers to real numbers:
6√3 = 10.3923
(3.5)^2 = 12.25
√75 = 8.660
9.8 = 9.8
57/5 = 11.4
A) Now order from largest to smallest:
(3.5)^2, 57/5, 6√3, 9.8, √75
B) We found the order by solving the equations to get real numbers.
C)
Since the numbers are multiplied by a negative number, the greatest number would be the smallest number because it would be closer to zero.
The order would be the reverse of part A:
x√75, 9.8x, 6x√3, 57x/5, x(3.5)^2
D) I replaced x with -1 and calculated for real numbers. All the values were the same as A except they were the negative value.
The way the equation is written
Solve for G:F = (G m^3)/r^2
F = (G m^3)/r^2 is equivalent to (G m^3)/r^2 = F:(G m^3)/r^2 = F
Divide both sides by m^3/r^2:Answer: G = (F r^2)/m^3
cost of 1 gallon gas = $2.09
cost of 3.785 litres gas = $2.09 ( 1 gallon = 3.785 litres)
cost of 1 litre gas = 2.09/3.785
cost of 18 litres gas = 2.09/3.785 * 18 = $20.982
