Answer:
see explanation
Step-by-step explanation:
to find the first 4 terms substitute n = 1, 2, 3, 4 into the sequence rule
to find the 10th term substitute n = 10 into the rule
(a)
a₁ = 1² + 3 = 1 + 3 = 4
a₂ = 2² + 3 = 4 + 3 = 7
a₃ = 3² + 3 = 9 + 3 = 12
a₄ = 4² + 3 = 16 + 3 = 19
a₁₀ = 10² + 3 = 100 + 3 = 103
(b)
a₁ = 2(1)² = 2(1) = 2
a₂ = 2(2)² = 2(4) = 8
a₃ = 2(3)² = 2(9) = 18
a₄ = 2(4)² = 2(16) = 32
a₁₀ = 2(10)² = 2(100) = 200
Answer:
C. 5i
Step-by-step explanation:
- The square root of a negative number is computed as the normal square root (square root of 25 is 5), but due to the negative sign, we must account for "i", which stands for the imaginary unit.
Hello!
The fraction is an improper fraction (the numerator is greater than the denominator). The whole number part of the mixed number is found by dividing the 24 by the 9. The fractional part of the mixed number is found by using the remainder of the division, which in this case is 6 (24 divided by 9 is 2 remainder 6).
Answer: 51% and .51
Step-by-step explanation: 51/100 squares are filled. Since it's already of 100, your decimal is 51. Move it twice to the left, your percentage is 51.
Hope this helps :)
