Answer:
$40.35
Step-by-step explanation:
First, solve for the sales price. Change the percentage into a decimal:
60% = 60/100 = 0.60
Next, multiply 0.60 with the original price, 97:
97 x 0.60 = 58.2
Subtract 58.2 from the original price:
97 - 58.2 = 38.8
Now, change the tax percentage into a decimal.
4% = 4/100 = 0.04
Multiply 0.04 with the sales price:
38.8 x 0.04 = 1.552
Add the sales price (rounded to nearest hundredth) to the sales price:
1.55 + 38.8 = 40.35
$40.35 is your answer.

Answer:
144
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
4(t -1)² = 4(7 -1)² = 4(6²) = 4(36) = 144

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)
