Answer:
36.9
Step-by-step explanation:
Given that the situation has been modeled by the formula:
B=1000e^(kt)
given that B=8520 after t=15 min
then the value of k will be solved as follows:
plugging in the values in the formula and solving for k
8520=1000e^(15k)
8.52=e^(15k)
solving for k
15k=ln(8.52)
hence
k=ln(8.52)/15
k=0.1428
k=0.143
5÷(4-3)×9-2
= 5÷1×9-2
= 5 × 9 - 2
= 43
You must solve the bracket first.After that,solve the multiplication and division,followed by addition and substraction if any.That's the theory to solve the right step
It would be D. If you add all the numbers (-18, -81, 144) and divide it by 3 then you would get -81. I hope I helped!
