Answer:
405500 x 1.24^18 =$19479651.89
$19479651.89 - $405500=$19074151. 89
$19074152
Answer:
Logan's average swimming speed = 0.625 metres/second
Mia's average swimming speed0.833 metres/second
Step-by-step explanation:
Speed is obtained by dividing the distance covered by the time taken to cover such a distance.
<em>It will be necessary to make sure we are working in seconds for our time units.</em>
Logan's swimming time: 1/3 hours will be = 20 minutes = 1200 seconds
Mia's swimming time: 1/4 hours will be = 15 minutes = 900 seconds
Logan swam 750 metres. Logan's swimming speed will be
750metres / 1200 seconds = 0.625 metres/second
Mia's distance swam is 3/3 of Logan's. If we reduce the fraction 3/3 to its lowest term, we will have that it will be = 1/1.
1/1 X 750metres = 750 metres.
This means that Mia swam exactly the same distance as Logan.
Mia's swimming speed = 750 metres/ 900 seconds = 0.833 metres/second
Answer:
x = 5, -5, 4i, -4i ;
Step-by-step explanation:
assume
Now the above equation is a quadratic equation.
There are two solutions of any quadratic equation. Solution of a quadratic equation is given by:
similarly there are two solutions of the quadratic equation which are:
Since
Therefore
; where (the numbers with 'i' are called imaginary numbers)
Therefore
4x + 2x< 5x-13
solve
6x < 5x-13
subtract 5x
x< (-13)
