Yes it is
it’s the 41st term
EXPLANATION:
the nth term would be 15n+35
because the terms go up by 15 and you add 35 to get to the term.
1. 2. 3. 4.
50. 65. 80. 95
1000- 35= 965
965/15=41

<h3>
Exponential function</h3>
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the amount of the substance after t hours.
From the equation, a = 100 mg
Also, after 6 hours:

After 24 hours:
y = 100(0.9966)²⁴ = 92.15 kg
The amount of radioactive material remaining after 24 hours is 92.15 kg.

First, use distributive property:
5(2r+6)-12r <em>The original expression; multiply 5 by 2r, and 5 by 6.</em>
10r+30-12r <em>Keep the -12r, just add it on to the end of the number(s) you found</em>
Next, use communitive property:
10r+30-12r <em>What we found in the previous step</em>
-2r+30 <em>Combine the like terms; 10r-12r=-2r, then place the 30 at the end</em>
Done! Your answer is -2r+30.
Hope that helps!
