290 million = 290,000,000
scientific notation would be 2.9 x 10^8
the 8 comes from the number of spaces you need to move the decimal point to the left to get 2.9
Answer:
5x^7 + 4x^4 - 2x^2 + 5x - 19
Step-by-step explanation:
Start by copying 5x -10 +3x^4 - 2x^2 here. Next, add x^4 to +3x^4, -9 to -10, and 5x^7:
5x - 10 +3x^4 - 2x^2
- 9 +x^4 + 5x^7
-----------------------------------------
5x - 19 + 4x^4 - 2x^2 + 5x^7
Now rearrange these terms in descending order by powers of x:
5x^7 + 4x^4 - 2x^2 + 5x - 19 (answer)
A1=-15
a2=a1+d→-4=-15+d→d=11
Answer:
17.32
