Answer:
log (25 x^5)
Step-by-step explanation:
2 log 5 + 5 log x
We know alog b = log b^a
log 5^2 + log x^5
We know log a + log b = log (a*b)
log ( 5^2 * x^5)
5^2 = 25
log (25 x^5)
Answer:
It would be a rational number.
Step-by-step explanation:
An easy way to tell if a number is rational is by seeing if it can be put in fraction form. As you can see, 27/100 is a fraction, so it is rational.
Answer:

along the direction 68.19° from north.
Step-by-step explanation:
Given,
- speed of the boat, u= 2 miles/hour along north
- speed of the river, v= 5 miles/ hour along east
Since, north and east are perpendicular to each other, so we can write the resultant velocity in vector form as,

Hence, the magnitude of resultant velocity can be written as



Hence, the magnitude of resultant vector is \sqrt{29} moles/hour.
And the direction of the boat can be given by,



= 68.19°
Hence, the resultant velocity of boat is
miles/hour along the direction making an angle 68.19° with the north.
So you subtract 40 from the original time and do that for each and so o. But the beginning time will be thet time minus 40
Answer:
78
Step-by-step explanation:
42+36=78
