Given:
<span>F= $335,000
n = 30 years at a fixed rate of i = 7.5%
Required:
the total cost of the principal
Solution:
F = P(1+i)^n
P = F/(1+i)^n
P = 335,000 / (1.0.075)^30
P = 38,264.05</span>
Answer:
8 to 53;45
Step-by-step explanation:
This is because 8 is the smallest and 53 is the biggest and the difference of 53-8 = 45

Answer:
The form of the sum of cubes identity is a³ + b³ = (a + b)(a² - ab + b²) ⇒ A
Step-by-step explanation:
To find the form of the sum of cubes identity ⇒ x³ + y³
- find the cube root of each one and add them in a small bracket ⇒ (x + y)
- square the first term in the small bracket and put it as the 1st term in a big bracket ⇒ (x² ....)
- put (-) after the 1st term ⇒ (x² - .....)
- multiply the 1st and 2nd term in the small bracket and put the product as the 2nd term in the big bracket ⇒ (x² - xy .....)
- square the 2nd term in the small bracket and add it to the terms of the big bracket ⇒ (x² - xy + y²)
Then the form of the sum of cubes identity is x³ + y³ = (x + y)(x² - xy + y²)
∵ a³ + b³ is a sum of two cubes
→ By using the same steps above
∵ = a and = b
∴ The small bracket is (a + b)
∵ Square a = a² and square b = b²
∵ a × b = ab
∴ The big bracket is (a² - ab + b²)
∴ The form of the sum of cubes identity is a³ + b³ = (a + b)(a² - ab + b²)
