235 x 40 = 9400
235 x 5 = 1175
9400 + 1175 = 10575
235 x 45 = 10575
Answer:
Step-by-step explanation:
a = -1
b = 2
c = 3
a + (-c) = -1 + (-3) = -4
Both numbers have same sign(-Ve).So add and the result will have the -Ve sign.
c - (-b) = c + b = 3 + 2 = 5
b = 2
Least to greatest: a +(-c) , b , c-(-b)
<span> half life i= 78 hours
amount after 78 hours is 395 kg:
395 = 790e^(k*78)
Dividing by 790 and taking natural log
ln (395/790) = (k*78)
-0.6931 = 78k
-0.00888 = k
lets calculate how much is left after 18 hours:
Amount(18)
= 790e^(-0.00888*18)
Amount = 673.301 kg
