Answer:
0.42
Step-by-step explanation:
divide 100÷42 then the answer is 0.42
-x + y = 4
2x + y = 1
-3x = 3
-3 -3
x = -1
2x + y = 1
2(-1) + y = 1
-2 + y = 1
+ 2 + 2
y = 3
(x, y) = (-1,3)
The dependent variable is y
the dependent variable is usually isolated on one side of the equation

The distance from the bottom of the wheel to a point on the ground can be modeled by a sine function. h(t)=a*sin(kt)+b. b is the height of the wheel, or 4m. a is the radius of the wheel, 50/2=25m. 2pi/k is the 5sinof thw revolution, so 2pi/k=6/3=2, k=pi. h(t)=25sin(pi*t)+4.
