Tan x = 8749/675
x= arctan (8749/675) arctan = tan^-1
x=85.59 degrees
Answer:
y=4
Step-by-step explanation:
Since the slope is constant, and the only y value for each x value is 4, then the equation is y=4.
Answer:
Step-by-step explanation:
From the question we are told that
Arc of 30 cm
10% reduction after each swing
Generally sum of geometric sequence is given by the equation
Mathematically solving for total distance traveled we have
Therefore the total distance traveled by the pendulum after 5 swings
The equation of proportional situation is y = ax.
Therefore your answer is y = -2x + 14
First thing you should do is reduce coefficients.
1st equation has all multiples of '2'. Divide by 2
---> x +3y = -6
2nd equation has multiples of 5. Divide by 5.
---> x - y = 2
Now elimination part is easier.
Eliminate 'x' variable by subtracting 2nd equation from 1st.
x + 3y = -6
-(x - y = 2)
----------------------
4y = -8
Solve for 'y'
4y = -8
y = (-8)/4 = -2
Substitute value for 'y' back into 2nd equation:
x - (-2) = 2
x + 2 = 2
x = 0
Solution to system is:
x=0, y =-2
