A perfect cube is a number that resulted from multiplying a number three times by itself. A perfect cube is also a number that has an exact cube root.
8x^12 ⇒ 2x^4 * 2x^4 * 2x^4
27x^9 ⇒ 3x³ * 3x³ * 3x³
Only two monomials are perfect cubes.
Answer:
1. ∠1 = 60
2. ∠2 = 40
3. ∠3 = 80
4. ∠4 = 80
5. ∠5 = 60
6. ∠6 = 120
7. ∠7 = 100
8. ∠8 = 60
9. ∠9 = 120
10. ∠10 = 100
Step-by-step explanation:
Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860
