Notice that 50 minutes is twice the half-life.
After 25 minutes, half of the starting amount remains, so that 88g decays to 44g.
After another 25 minutes (a total of 50 minutes), the 44g will decay to 22g.
(-4, 3, 10). I'm not really sure tho
Answer:
Step-by-step explanation:
25b * (3a² - 1) = 25b * 3a² - 25b * 1
= 75ba² - 25b
Distributive law upon subtraction:
a(x - y) = ax - ay
It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
The answer is $4270
add 9500+1500+1870=12870 then subtract your savings 12870-6100=6770 then subtract your scholarship 6770-2500=4270
