It would be 2/3 because 2 divided by 3 on a calculator is .6667
Answer:
D
Step-by-step explanation:
If we use the calculator will find out that x= √151/2 ≈ 6.1441
D. 6 < x < 7
x is less then 7 and greater than 6
Without the calculator you can think that 151 is almost 144 that is 12² so
we can approximate √151 to be a bit more then 12
√151/2 = a bit more then 12 /2 = 6 and a bit more
Answer: (i) 1 (ii) 3/4 , √3/3 (iii) 0 (iv) 1
<u>Step-by-step explanation:</u>
ΔRPQ is 1 30°-60°-90° triangle <em>because RQ = 2PQ</em> , where
(i) sin² (90°) = 1² = 1
(iii) sin (90°) × cos (90°) = 1 × 0 = 0
(iv) sin² (90°) - cos² (90°) = 1² - 0² = 1
Answer:
5, 8, 11 and 32
Step-by-step explanation:
For the first 3 terms, substitute n = 1, 2, 3 into the n th term formula
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
a₃ = 3(3) + 2 = 9 + 2 = 11
Similarly for tenth term, let n = 10
a₁₀ = 3(10) + 2 = 30 + 2 = 32
