Answer:
Step-by-step explanation:
Cos(65°) = √(1 + cos(130°)) / 2
0.42=√(1 - 0.64)/2
0.42=√(0.36)/2
0.42²=√0.18²
Answer:
A set of parametric equations for the line y = 4x - 5 is;
x = t
y = 4t - 5
Step-by-step explanation:
To find a set of parametric equations for the line y = 4x - 5;
We can assign either variable x or y equal to the parameter t, in this case we can easily let x = t
We then substitute x = t in the original equation;
y = 4t - 5
Therefore, a set of parametric equations for the line y = 4x - 5 is;
x = t
y = 4t - 5
