Step-by-step explanation:
Try each choice to see which one works.
A.)
a_n = 4n + 10
a_5 = 4(5) + 10 = 30
a_6 = 4(6) + 10 = 34
a_7 = 4(7) + 10 = 38
Answer: A.)
Answer:
log (16)=2 in base 3x-5
==>16=2^(3x-5)
==>2^4=2^(3x-5)
==>4=3x-5
==>3x=9
==>x=3
Step-by-step explanation:
The amount to be paid in rent after 2 years if the rent as of now is $3,000 will be; $3,213.675
The question allows that we choose the amount being paid as rent as of now.
Let the rent paid as of now be; $3,000
In essence; after the first year; the amount increases by 3.5% to become;
After the second year; we have;
Ultimately; the amount to be paid after 2 years will be; $3,213.675.
When given the opportunity to change rent contracts;
- A situation that will be beneficial would be a 3.5% reduction in rent per year
- A situation that will not be beneficial would be a 7% increase in rent per year.

About 92 days are taken for 90 % of the material to <em>decay</em>.
The mass of radioisotopes (
), measured in milligrams, decreases exponentially in time (
), measured in days. The model that represents such decrease is described below:
(1)
Where:
- Initial mass, in milligrams.
- Current mass, in milligrams.
- Time constant, in days.
In addition, the time constant is defined in terms of half-life (
), in days:
(2)
If we know that 
, 
and 
, then the time required for decaying is:
About 92 days are taken for 90 % of the material to <em>decay</em>.

Answer:
One Solution
Explanation:
7(y + 3) = 5y + 8
Simplify both sides of the equation
7(y + 3) = 5y + 8
(7)(y) + (7)(3) = 5y + 8 (Distribute)
7y + 21 = 5y + 8
Subtract 5y from both sides
7y + 21 − 5y = 5y + 8 − 5y
2y + 21 = 8
Subtract 21 from both sides
2y + 21 − 21 = 8 − 21
2y = −13
Divide both sides by 2
2y = −13
2y / 2 = -13 / 2
y = -13 / 2
-13 / 2 = -6.5
y = -13 / 2 or -6.5
