Answer:
1) 5×5×5
2) False
3) False
Step-by-step explanation:
5³ basically means 5 is multiplied thrice, i.e
5 × 5 × 5
4² = 4×4 = 16
4² is 16, not 8
(-3)² = -3 × -3 = 9
-(3)² = -9
Answer:
Step-by-step explanation:
<u>Sum of infinite GP is</u>:
<u>The second term is</u>:
<u>Eliminate r in the system:</u>
- a/(1-r) = 16 ⇒ a = 16 - 16r ⇒ 16r = 16 - a ⇒ r = 1 - a/16
- ar = -0.5 ⇒ r = -0.5/a
<u>Compare the two equations and solve for a:</u>
<u>Multiply both sides by 16a:</u>
- 16a - a² = -8
- a² - 16a = 8
- a² - 16a + 64 = 72
- (a - 8)² = 72
- a - 8 = ±√72
- a = 8 ± √72
- a = 8 + 6√2
- a = 8 - 6√2, excluded as it is negative and makes common difference positive and so an increasing function
a = 8 - 6√2 = -0.4852 ⇒ r = -0.5/a = -0.5/-0.4852 = 1.03 > 1
PART A)
multiply total weight by percentage:
eagle eats 8 pounds 70% is fish
8 x 0.70 = 5.6 pounds of fish
bear eats 110 pounds 35% is fish
110 * 0.35 = 38.5 pounds of fish
5.6 + 38.5 = 44.10 pound total
Part B) 125 - 110 = 15
15 / 110 = 0.136 = 13.6% increase
