Answer:
0,00027 grams!
Step-by-step explanation:
This is a scientific notation problem.
When a number is followed by a 
, it means that said number has one zero at the beginning.
In this case, the number is followed by 
, so that means that 2.7 has four zeros at the beginning. So, 2.7x grams is equal to 0,00027 grams! (always the comma goes after the first zero).
Answer:
Either 10+5 or 10-5
Step-by-step explanation:
Coefficient- the number that is multiplied by the variable
Constant- a number that stays the same and is not changed no matter what x or y equals.
The area of a rectangle is Base x height whereas the area of a triangle is Base x height divided by 2
The falling stone is a certain instant 230 feet above the ground. 3 seconds later it is only 14 feet above. The height that it was dropped is 32 feet. The equation for the answer is;
<span>16<span>t2</span>+<span>h0</span>=230</span>
<span>−16(t+3<span>)2</span>+<span>h0</span>=14</span>

Answer: (n-1)^2</h3>
This is because we have a list of perfect squares 0,1,4,9,...
We use n-1 in place of n because we're shifting things one spot to the left, since we start at 0 instead of 1.
In other words, if the answer was n^2, then the first term would be 1^2 = 1, the second term would be 2^2 = 4, and so on. But again, we started with 0^2 = 0, so that's why we need the n-1 shift.
You can confirm this is the case by plugging n = 1 into (n-1)^2 and you should find the result is 0^2 = 0. Similarly, if you tried n = 2, you should get 1^2 = 1, and so on. It appears you already wrote the answer when you wrote "Mark Scheme".
All of this only applies to sequence A.
side note: n is some positive whole number.
