Recall that
d/dx sech(x) = - sech(x) tanh(x)
d/dx tan⁻¹(x) = 1/(1 + x²)
Then by the chain rule,
dy/dx = - sech(x) tanh(x) / (1 + x²)
Luis earns a solid $150 and that doesn't change, now you need to calculate 14% of $6,050.
x=150+(0.14x6050)
150+(847)
997
Luis was paid $997.
If all 3 angles of a Triangle MUST equal 180°, then we know that we use the equation (for this triangle) to find the angle measurements as (180-90)/2 which means we are dividing 90/2 which is 45° for each angle. But these angles are different measures, so we have to guess upon this and say that YOUR ANSWER IS D
Answer:
45
Step-by-step explanation:
the left and right side are symetrical
