CaHeK987 [17]

1. Factor out the greatest common factor (GCF). (There will not always be one). 2. Count the number of terms.
3. Check to be sure each factor is prime, if not, repeat 1-3.
4. Check by multiplying the factors out to see if you get the original polynomial.

T²= 4π² (M+m) ÷ ug

inessss [21]

Starting with ...

$T^2=\dfrac{4\pi^2(M+m)}{ug}$

1) Multiply by the inverse of the coefficient multiplying the sum with M, then subtract m.

$\dfrac{T^2ug}{4\pi^2}=M+m\\\\M=\dfrac{T^2ug}{4\pi^2}-m$

2) Multiply by g/T²

$g=\dfrac{4\pi^2(M+m)}{T^2u}$

Kiran starts at 9:00 am by bicycle to reach office. She cycles at the speed of 8 km/hour and reaches the office at 9:15 am. By h

Ivenika [448]

Answer:

v = 12 km/h

Step-by-step explanation:

To find how much she should increase the speed first we need to find the distance traveled:

$d = v*t$

Where:

d: is the distance traveled =?

v: is the velocity = 8 km/h

t: is the time = 15 min (9:00 to 9:15)

$d = v*t = 8 km/h*15 min*\frac{1 h}{60 min} = 2 km$

Now, we can find the speed:

$v_{f} = \frac{d}{t} = \frac{2 km}{10 min*\frac{1 h}{60 min}} = 12 km/h$

Therefore, she should increase the speed to 12 km/h to reach the office at 9:10 am.

I hope it helps you!
