Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx


Answer:
46 hours
Step-by-step explanation:
1. add all the hours you've worked (41+49+48+46=184)
2. divide the sum by the number of weeks (184/4=46)
<span>Volume = 4/3*pi*r^3
As diameter = 6 inches
Radius = Diameter / 2
Radius = 6/ 2
Radius = 3 inches
Putting the value of r in the formula :
=4/3*pi*3^3
</span><span> =4/3*pi*27
</span>= 36*pi
So according to above explanation,
<span>B) V = 36 π cubic inches , is the correct answer.</span>
(x - 8)^2 = 144
take the sq rt of both sides
x - 8 = 12
x = 12 + 8
x = 20
20 feet by 20 feet
