x=40
General Form is the most basic form of an equation and is used as a template to form equations designed to solve a specific problem.
The equation given is "<span>(x- -1)^2 +(y-1)^2 =225.0".
The general form of this Equation would be presented as
</span>·X (+/-) Y = Z
·X^2 (+/-) Y^2 = R1

Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
Answer:
20 rides
Step-by-step explanation:
Let x represent how many rides you take.
Option A's cost can be represented by 0.8x + 30.
Option B's cost can be represented by 2.3x.
Set these expressions equal to each other, then solve for x:
0.8x + 30 = 2.3x
30 = 1.5x
20 = x
So, the costs will be the same at 20 rides
Amount of increase = 95-80 = 15
Percent increase = (15/80) x 100
Percent increase = 18.75%
