Answer:
-2
Step-by-step explanation:
n(-2) = -1 - (-2) + 4 = -1 + 2 + 4 = -1 + 6 = 5
( - 1 , 6 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [6] is +. So, result is 5)
n(0) = -1 - 0 + 4 = -1 + 4 = 3
n(5) = - 1 - 5 + 4 = -6 + 4 = -2
( -6 , 4 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [-6] is -. So, result is -2)
Answer:
D
Step-by-step explanation:
This is exponential growth, and to my understanding, the format goes:
<em>initial amount (percent growth/ decay)^time</em>
percent growth = (<em>decimal percent + 1)</em>
<em>percent decay = (1 - decimal percent) </em>
Your equation:
1500(1.02)^t
Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.
i think
4h+3=3.5h+6
0.5h+3=6
0.5h=3
h=6
Final answer: 6 hrs
