Answer:

The number of watches made is 8

Step-by-step explanation:

SO the equation is C=15n+85 where C is the total cost and N is the amount of watches

1)plug in C

385=15n+85

2)move 85 to the other side so it would become -85

385=15n+85 → 385-85=15n → 100=15n

3)divide 15 from both sides

100/15=15n/15 → 25/3=n

since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)

The radius of a circle is 3 what is the circumference?
Alika [10]

Answer:

6π

Step-by-step explanation:

You have to use the formula for the circumference of a circe:

Circumference = π(diameter)

However, you do not have the diameter, you have the radius.

Diameter = radius * 2

Diameter = 3 * 2

D = 6

Now you can substitute this value back into the Circumference formula:

C = πd

C = 6π

Find the derivative of f(x)=2arcsin(x-1)
andreev551 [17]
Since \dfrac{\mathrm d}{\mathrm dx}\arcsin x=\dfrac1{\sqrt{1-x^2}, you have

\displaystyle\frac{\mathrm d}{\mathrm dx}2\arcsin(x-1)=2\frac{\mathrm d}{\mathrm dx}\arcsin(x-1)=2\frac{\dfrac{\mathrm d}{\mathrm dx}(x-1)}{\sqrt{1-(x-1)^2}=\frac2{\sqrt{2x-x^2}}
