            3x^2 - 2x - 1

x + 2 Γ 3x^3 + 4x^2 - 5x - 2
            3x^3 + 6x^2
                      -2x^2 - 5x - 2
                      -2x^2 - 4x
                                  -x - 2
                                  -x - 2
                                     0

Therefore, solution is 3x^2 - 2x - 1

A regular square pyramid just fits inside a cube (the base of the pyramid is congruent to a face of the cube and
zlopas [31]
Volume of reg sq. pyramid = vp
vp = 1/3×s^2×h, where s = side and h = height
Volume of cone = vc =1/3×h×pi×r^2
Now we know that h is the same for both, and the cones diameter = s of square base, so radius (r) = 1/2 s
so now vc = 1/3×h×pi×(1/2s)^2
let's remove the same items for both vc and vp
so 1/3 and h
now let's plug an arbitrary number into each:
vc = pi (10/2)^2 = 3.14×25 = 78.54
vp = s^2 = 10^2 = 100
So any square pyramid has slightly more volume than the cone

cara works at a fine jewelry store and earns a commission on her total sales for the week. her weekly paycheck was in the amount
Gekata [30.6K]

Cara's rate of commission is 12%.

Step-by-step explanation:

Given,

Paycheck = $6500

Salary = $1000

Commission = Paycheck - Salary

Commission = 6500-1000 = $5500

Total sales for the week = $45000

Commission rate = \frac{Commission}{Total\ Sales}*100

Commission\ rate=\frac{5500}{45000}*100\\\\Commission\ rate=\frac{550000}{45000}\\\\ Commission\ rate=12.22\%

Rounding off to nearest whole number.

Commission rate = 12%

Cara's rate of commission is 12%.

How many pounds of carbon dioxide would you prevent from entering the atmosphere in one year, if you were to replace a 100-watt
VikaD [51]
That's an excellent question but we don't have enough information to answer it. We would need to know how the electrical energy is generated. Nuclear, hydroelectric, coal burning, wind, and natural gas burning all produce different amounts of carbon for the same amount of electrical energy. If the utility that supplies your house uses nuclear or wind, then you can leave both bulbs shining 24/7 and they're not responsible for any carbon.
