Answer:
32w^3 + 16x^2 - 8
Step-by-step explanation:
Perimeter = 2L + 2W
L = 9W^3 + 8W^2, W = 7w^3-4
2(9w^3 + 8w^2) + 2(7w^3 - 4)
= 18w^3 + 16w^2 + 14w^3 - 8
Combine like terms
32w^3 + 16w^2 - 8
Answer:
cp of 55 shares = 3.50 * 55 = 192.5
commission amount = 1% *192.5 = 1.925
Total invest = 192.5 + 1.925 = 194.425
sp of 1 share = 2
sp of 55 share = 2*55 = 110
Earning from shares = 110
since earning is less than invest, Laura has loss of (194.425 - 110) = 84.425
To find the length of the arc, we will use the formula,
arc length = 2πR (C/360)
where,
R is the radius of the arc, which is 8"C is the central angle, which is 45°
pi is approximately equivalent to 3.14
Applying the formula,arc length = 2πR (C/360)
arc length = 2(3.14)R (45°/360)
arc length = (6.28)(8") x (0.125)
arc length = (50.24") (0.125)
arc length = 6.28"
The length of the arc is 6.28". 6.28 is also equivalent to 2π, hence, the answer is 2π.
