The number of subscribers y to a newspaper after t years is shown by the equation , where 75 is the initial number of subscribers to a newspaper and t is the time period is years.
The above equation can be rewrite as
which is equivalent to the exponential decay function with rate r=0.05=5%
⇒ The number of subscribers to a newspaper decreased by 5% every year.
2,567 / 4 = 641.75 Hope this helps.
Answer:
He raised $25.50 over his fund raising goal
Step-by-step explanation:
Here, we want to calculate his fund raising goal.
Let his fund raising goal be $x
We are told that he raised 151% of his fundraising goal;
Thus,
mathematically;
151% of x = 75.5
151/100 * x = 75.5
151x = 100 * 75.5
151x = 7550
x = 7550/151
x = $50
So the amount he raised over his fund raising goal will be $75.50 - $50 = $25.50
Answer:
No solutions
Step-by-step explanation:
Isolate the absolute value:
|x−1| + 5 = 2
Subtract 5 from both sides:
|x-1| = -3
Since an absolute value can never be equal to a negative number, there are no solutions.
