Step-by-step explanation:
the answer for this question is
-2 and 6
If the equation is (-13) x (817), then the product is (-10621).
Answer:
Step-by-step explanation:
Each of the following 17 is 17 more than its corresponding integer in the 1st 17.
---> 306 + 289 = <em>595</em>
Answer:
First step to solving the equation is to subtract 10 on both sides:
10 - 10 + 5x =65 -10
5x = 55
Then, we divide by 5 on both sides!
5x ÷ 5 = 55 ÷ 5
x = 11
Our result is 11, so the answer to the problem is 11

Half-life, h = 13 hours
Mass initial, a = 38 g
B=base for half-life = 2
(a)
I(t)=a*B^(-t/h)=a*(B^(1/h)^(-t)=a*(B^(-1/13))^t
Substituting values,
I(t)=38*(2^(-1/13))^t
a=38 g
b=2^(-1/13)=0.9480775 (approximately)
=>
I(t)=38*0.9480775^t
(b) I(t)=7
solve
I(t)=7=38*0.948077^t
Take log on both sides and solve for t
t=log(7/38)/log(0.948077)
=31.727 hours.
Check: I(31.727)=38*9.948077^(31.727)=7.000 g ok
