The least positive integer will be 17.
Explanation
Lets assume, the integer is
As the square root of this integer needs to greater than 4, that means....
Thus, the integer should be greater than 16
So, the least positive integer with a square root greater than 4 will be 17.
Step-by-step explanation:
given,
total membersin grp =20
no.of boys =7
no.of girls=20-7=13
so,
the ratioof girlsto boys is =13:7
hope this answer helps youdear...take care and may u have a great day ahead!
Answer:
After 7 months months the population of both the town will be equal.
Step-by-step explanation:
Let's assume, the population of both towns will be equal after x number of months.
Every month 125 people move out of the town and 200 people move into the town, where already 43,425 people are living. So, the population of the former town after x months is,
Every month 150 people move out of the town, where already 45,000 people are living. So, the population of the latter town after x months is,
when the population of both of the towns are same,then
Answer:
At t = 3, pilot can hit the target located at the origin.
Step-by-step explanation:
We have been given displacement vector:
r(t) = 5 - t, 21 - t², 3-t³/27
so, in this case r(t) and r'(t) should be in the parallel but opposite direction.
In order to get r'(t) we need to differentiate r(t).
r(t) = 5 - t, 21 - t², 3-t³/27
r'(t) = -1, -2t, -t²/9
Now perform the cross product among these two r(t) and r'(t).
r'(t) x r(t) =
= i ((-6t + )+ ( - )) -j ((-3 + + - )) + k ((-21 + + 10t -2))
= ( + - 6t )i + ( - +3) j + (-t² + 10t -21)k
In order to find the value of t, we need to put
+ - 6t = 0
-t² + 10t -21 = 0
So, after solving for t, we will get
- ( t-3) (t-7) = 0
t = 3 or t = 7
In this case, only t = 3 satisfies the other two equations as well. t=7 is not satisfying. So take t =3 as the time. and for further assurance, we need to check are our vectors r(t) and r'(t) opposite at t = 3 or not. Let's check it out.
r(3) = 5-3, 21 - 3², 3 - 3³/27
r (3) = 2, 12, 2
r'(3) = -1, -2(3) , -3²/9
r'(3) = -1, -6 -1
Here, we can easily see that, r(3) = -2 r'(3) which is opposite and hence it is proved that, at exactly t = 3, pilot can hit a target located at the origin.
