X=25cos10+30cos100
y=25sin10+30sin100
v=√(x^2+y^2)
α=tan(y/x)
Rounding to two decimal places in intermediate steps...
x≈19.41, y≈33.89
v≈39.05
α=60.20°
So (39.05, 60.20°)
Your answer is 7.41666666667
Hi there! The answer is D.
Function
f(x) = 7x - 6.
To find the inverse we need to switch the places from x and y.
y = 7x - 6
x = 7y - 6
-7y = -x - 6
7y = x + 6
y = (x + 6) / 7
.026 because 2.6%*100 is 0.026
