The 10th position is the 6 right after the dot. The numeral right after the 6 is closer to the next number. So by rounding it, it becomes 9.7 If the digit to the right is 5 or more, you go up a numeral. If it is 4 or less, you keep it at the numeral that it is. If it had been 9.64 then we would have kept it at 9.6 Hope this helps
Answer:
3
Step-by-step explanation:
4(a) The first 3 terms are:
₅C₀ (3)⁵ (bx)⁰ = 1 × 3⁵ × 1 = 243
₅C₁ (3)⁴ (bx)¹ = 5 × 3⁴ × bx = 405b x
₅C₂ (3)³ (bx)² = 10 × 3³ × (bx)² = 270b² x²
4(b) The coefficient of x² (the third term) is twice the coefficient of x (the second term).
270b² = 2 (405 b)
270b² = 810b
270b = 810
b = 3

When you have -(-2) it equals +2 and the same goes for any other number. When you have +(-2) it equals -2 and the same goes for any other number. Hope this helps!
