You would multiply the amount by 1.70 for example increasing £50 by 70% would be £85
Answer:

Step-by-step explanation:
The temp is 100 at time t = 0
After 1 sec, the temp difference would be:

After 2 sec, the temp difference would be:

Similarly for 3 seconds, 4 seconds etc.
We notice that the parenthesis part is 40% of it, so we can also write:
100(40%)^t,
where
t is the time
40% can be written as 40/100 = 0.4
SO, the function is:

Answer:
C=9 or c=-7
Step-by-step explanation:
|-5c+5|=40
-5c+5=-40 or - 5c+5=40
-5c=-40-5. - 5c=40-5
-5c=-45. - 5c=35
C=9. C=-7
Slope = (y2 - y1)/(x2 - x1) = (-1 - 17)/(-8 - (-10)) = -18/(-8 + 10) = -18/2 = -9
Answer:
2m^4 - 11m³ + m + 8
Step-by-step explanation:
(2m - 5m³) - (5m + 3m³ - 7m^4) + (8 - 3m³ - 5m^4 + 4m)
2m - 5m³ - 5m - 3m³ + 7m^4 + 8 - 3m³ - 5m^4 + 4m
7m^4 - 5m^4 - 5m³ - 3m³ - 3m³ + 2m - 5m + 4m + 8
2m^4 - 11m³ + m + 8
