Hi Friend,
Solution is as follows!
Pupils in ROSE SCHOOL = 2185
GIVEN THAT,
there are 307 people more in lily school
HENCE,
people in LILY school will be = 2180 + 307 =<span>2487.
</span>
ROUNDING OFF TO NEAREST 10 we get
<span>2490.
</span>____________________________________________________________
(ii)TOTAL NUMBER OF PUPIL IN BOTH ROSE AND LILY SCHOOL=
2185+2487=<u><em>4672</em></u>
ROUNDING OFF TO nearest 100 we get
<u>2500
</u>
HOPE THIS HELPS!!!
D= (12)/(3)(4)
d = 12/12
d = 1
3)Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years
Formula for compounding is:

Using the values, we get:

Therefore, the compounded amount will be $9853.70
4)Principal Amount = P = $7200
Compounded Amount = A = $9853.70
Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70
Therefore, $2653.70 will be earned as interest over a period of 8 years.
Treat this as you would the quadratic equation x^2 - 4x - 3 + 0. Solve this by completing the square:
x^2 - 4x + 4 - 4 - 7 = 0
(x^2 - 4x + 4) = 11
(x-2)^2 = 11, and so x-2 = plus or minus sqrt(11).
Graph this, using a dashed curve (not a solid curve). Then shade the coordinate plane ABOVE the graph.
Answer:
to the right of zero if postive if negative left
