Answer:
A
Step-by-step explanation:
2x² - 12x - 14
2(x² - 6x - 7)
2(x² - 7x + x - 7)
2(x - 7)(x + 1)
Answer:
s(t) = 10000·1.65^t
Step-by-step explanation:
The general form of an exponential model is ...
f(t) = (initial value) × (1 +(fractional change))^t
where the fractional change can be positive or negative and t is the number of time units. Each time unit will correspond to the period required for the fractional change.*
__
For your problem, you have (initial value) = 10,000 and (fractional change) = 65% = 0.65 with time units of 1 year. Your function for sales (s) will then be ...
s(t) = 10000·1.65^t
_____
* The business regarding time units has to do with problems where you get a description like "increased 30% in 4 hours." Then, if t is in hours, the multiplier of the initial value looks like 1.30^(t/4).
Solutions
1) Find the least common denominator of 7/10 and 1/5.
10: 10
5 : 5 , 10
The least common denominator is 10.
2) Make the denominator of 1/5 to 10. Multiply numerator and denominator by 2.
1 x 2 = 2
5 x 2 = 10
3) New fraction
7/10 + 2/10
4) Add
7+2 = 9
9/10 is answer
9/10 can not be simplified. It is already in reduced form.
