Answer:Yes,No,No,Yes
Step-by-step explanation:
Complete question is;
Suppose that a dimension x and the area A = 2x² of a shape are differentiable functions of t. Write an equation that relates dA/dt to dx/dt.
Answer:
Step-by-step explanation:
Since A = 2x²
Let's differentiate both sides with respect to x.
dA/dx = 4x
Now, we want to find the relationship between dA/dt and dx/dt
dA/dt can be expressed as;
(dA/dt) = (dA/dx) × (dx/dt)
Thus;
dA/dt = 4x(dx/dt)
Thus, the equation that relates dA/dt to dx/dt is;
dA/dt = 4x(dx/dt)

Answer:
$13.25
Step-by-step explanation:
First you add everything up to get you to $15.70, then the 20% is changed to .2 which you then multiply 15.70 by .2 giving you 3.14. You then take 15.70 minus 3.14 which then gets you to 12.56. Then you take the tax of 5.5% and times $12.56 by it, giving you 69 cents, as your tax. Add those together to get 13.25, and then your finished.
