Step-by-step explanation:
Part (a)
<h3>Answer:
</h3>
---------------------
Explanation:
Multiply by 1000 to go from km to meters.
This is because 1000 m = 1 km.
Multiplying by 1000 in scientific notation means we add 3 to the exponent 5. The 3 is because 1000 = 10^3.
So the becomes

Part (b)
Answer in standard form: 960,000 seconds
Answer in scientific notation:
---------------------
Work Shown:
To go from the scientific notation to standard form, move the decimal point 5 spaces to the right. The 5 is from the exponent.
Angles on a straight line add up to 180° so you do 180 take away 115 which gives you Y angle and then angles in a triangle add up to 180 so you do 45 add 65 and you get 110 which then u take away from 180 to get 70 answer D
If you want a sequence that subtracts 6 each time, then we'd have to have a nth term.
125, 119, 113 etc will be your pattern
Since we are subtracting 6 each time, the nth term will start with -6n
Then we see what that equation looks like: -6 as the first term, -12 as the second etc.
So we have to add a certain amount so the sequence starts at 125, which is to plus 131 to get to 125.
So now the pattern starts at 125 and decreases by 6 each term.
So U_n = -6n + 131
