<u>Answer:</u>
She paid 26.35 for something that would usually be 31 dollars. The percentage discount she got is 15%
<u>Solution:</u>
A lady paid $26.35 for something that is usually $31, so she got a discount for the product.
Now, we have been asked to find out how much percentage discount she got.
To do that we first have to check how many dollars she got off the product.
To do so we have to subtract the discounted price from the initial price.
Therefore we get:
31 - 26.35 = 4.65
To find the percentage discount we need to do the following
Therefore she got a discount of 15%
Answer:
Step-by-step explanation:
x = cos θ + sin(10θ)
y = sin θ + cos(10θ)
Take derivative with respect to θ:
dx/dθ = -sin θ + 10 cos(10θ)
dy/dθ = cos θ - 10 sin(10θ)
Divide:
dy/dx = (dy/dθ) / (dx/dθ)
dy/dx = (cos θ - 10 sin(10θ)) / (-sin θ + 10 cos(10θ))
Evaluate the derivative at θ=0:
dy/dx = (cos 0 - 10 sin 0) / (-sin 0 + 10 cos 0)
dy/dx = 1/10
Evaluate the parametric functions at θ=0:
x = cos 0 + sin 0 = 1
y = sin 0 + cos 0 = 1
Writing the equation of the tangent line in point-slope form:
y - 1 = 1/10 (x - 1)
