Answer:
a₁ = 707 a₂ = 713
Step-by-step explanation:
the nth term of an arithmetic sequence is
= a₁ + (n - 1)d
a₁ is the first term, d the common difference , n the term number
given
a₅₀ = 1001 , then
a₁ + 49d = 1001 ← substitute d = 6
a₁ + 49(6) = 1001
a₁ + 294 = 1001 ( subtract 294 from both sides )
a₁ = 707
and a₂ = a₁ + d = 707 + 6 = 713
When adding numbers in scientific notation, the exponents must be the same. Owen is correct and Toshi is incorrect.
When adding numbers in scientific notation, the exponents must be the same.
Toshi suggests using the expression (490 × 10⁷) + (4.1 × 10⁷), but this is incorrect because the exponents do not match.
Owen suggests using the expression (4.9 × 10⁹) + (0.041 × 10⁹), and this is correct because the exponents are the same.
So, Owen is correct and Toshi is incorrect.

The Distributive Property is applied to -3(8x - 4) by multiplying -3 by each term inside the parenthesis, which gives the expanded form -24x + 12.
To use the Distributive Property to expand -3(8x - 4), you need to multiply each term inside the parenthesis by -3.
Now combine the two products you obtained:
-24x + 12
Therefore, the expanded form of -3(8x - 4) using the Distributive Property is -24x + 12.

Step-by-step explanation:
If Marian travels, by car, on the highway. At 10 and 35 minutes he is at kilometer 25. After a period of time, at 11 and 15 minutes, he is at kilometer 100.
Total distance covered = 25km + 100km
Total distance covered by Marian = 125km
Total time taken by marian = 10hr 35min + 11hr + 15min
Total time taken by marian = (10+11)hr + (35+15)min
Total time taken by marian = 21hr 50mins
Total time taken by marian = 21 * 50/60 hr
Total time taken by marian (Duration) = 21.833hr
Average speed = Total distance covered/Total time taken
Average speed = 125/21.833
Average speed = 5.725km/hr
Convert to m/s
5.725km/hr = 5.725*1000/3600
5.725km/hr = 5725/3600
5.725km/hr = 1.5903 m/s
Hence the average speed expressed in SI unit is 1.5903 m/s
