I'm assuming the problem is nine to the third power divided by nine to the ninth power, so the answer would be **0.000001882****.**** **Fraction form would be **1****/****531441****.**** **

Sorry about the first answer, I read the problem wrong.

A(w) = 50w-w^2

rewrite it as y = -w^2 +50w

using quadratic formula y = ax^2 +bx +c

a would equal -1, b = 50 and c = 0

find the axis of symmetry using x = -b/2(a)

so x = -50 / 2(-1) = -50/-2 = 25

so the width = 25 m

the greatest area is a square, so area = 25^2 = 625 square meters

**Answer:**

1046 pounds

**Step-by-step explanation:**

The volume of the hemisphere is given by the formula ...

V = 2/3πr³

where r is the radius, or half the diameter.

The radius is (4 ft)/2 = 2 ft, so the volume of the tank is ...

V = (2/3)π(2 ft)³ = 16/3π ft³ ≈ 16.755 ft³

Then the weight of the water in the tank is ...

(16.755 ft³)(62.4 lb/ft³) ≈ 1045.52 lb

**The total weight of the water is about 1046 pounds**.

Answer: Question 3. 1) B=60 degrees

Step-by-step explanation: Angles on a straight line=180 so if u have 120 all you have to do is minus 180 from 120 which gives you 60.
