Answer:
29
Step-by-step explanation:
Each number has 4 in difference
So, since the initial fee is $50, and every hour is $15, if h is equal to hour, the equation would be like this:
50 + 15h = 110.
Then, if we want to get the answer, we need to solve the equation.
First we pass the 50 to the other side, like this:
15h = 110 - 50
15h = 60
Then we pass the 15 dividing like this:
h = 60/15
h = 4
And we get four!
So the answer is: 4.

Answer:
8(cos(π) +i·sin(π))
Step-by-step explanation:
The number in parentheses has a magnitude of ...
√(1^2 +(√3)^2) = √4 = 2
Then the cube of that number will have a magnitude of 8, eliminating the 2nd and 4th choices
The angle of the number in parentheses is ...
arctan(-√3/1) = -π/3
Then 3 times that angle will be -π, also π.
The number of interest has a magnitude of 8 and an angle of π, so is written in the desired form as ...
8(cos(π) +i·sin(π)) . . . . . matches the 3rd choice
Step-by-step explanation:
let the eqn be y - y1 = m (x - x1)
sub (-2, 3) and m = -4:
y - (-2) = -4 (x - (-2))
y + 2 = -4 (x + 2)

Answer:
1. L1 = 
2. O2 = 
Step-by-step explanation:
Given: x = 
1. To make L1 the subject of formula;
x =
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
collect like terms,
L2 = xL1(O2 - O1) + L1
factorize the right hand side;
L2 = L1[x(O2 - O1)]
L1 =
2. To make O2 the subject of formula;
x =
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
open the bracket to have;
L2 - L1 = xL1O2 - xL1O1
⇒ xL1O2 = L2 - L1 + xL1O1
O2 = 
=
