Answer:
4 is the answer bc from 2 to 3 the output goes up 4 and from 3 to 5 the in put goes up 2 while the output goes up 8 meaning the input 4 would be up 4 from 3
Step-by-step explanation:
25^(n-3)=5^(n+8)
Remember: 25=5²
Therefore:
5^[(n-3)²]=5^(n+8)
5^(2n-6)=5^(n+8)
Then:
2n-6=n+8
2n-n=8+6
n=14
Answer: n=14

<span>Speed
is calculated as distance covered, divided by the time taken to cover that
distance. In this case, the sales person covered 50KM in 45minutes (which can
also be expressed as 3/4 hours). To calculate the speed he used to cover this
distance, we divide the distance covered by the time taken. So 50km/3/4hours.
This gives us 66.67km/hr. In order to calculate the amount of time the
salesperson used to travel from the office to the sales person, we calculate
as follows 250km/66.67km/hr. This gives us a total of 3.75 hours or 3 hours 45 minutes.</span></span>
22.7%
Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%
