(2^8 . 5^-5 . 19^0)^-2
using PEMDAS
this = (2^8 * 1/5^5 * 1)^-2
= (5^5 / 2^8)^2
= 5^10 / 2^16
Answer:
24.83 hours
Step-by-step explanation:
Given that :
Let time taken by pumps be :
Pump A = 60 hours
Pump B = 80 hours
Pump C = 90 hours
Recall :
Rate = 1 / time taken
The rates of the pumps are :
Pump A rate = 1 / 60
Pump B rate = 1/80
Pump C rate = 1/90
Combined rate : 1/60 + 1/80 + 1/90
Combined rate = (12 + 9 + 8) / 720 = 29/720
Combined rate = 29/720
The time taken together will be :
1 / combined rate = 1/(29/720) = 720 / 29 = 24.827 hours
Answer:
lcm
Step-by-step explanation:
2 will be the LCM whereas both denominator we can divide by 2
Answer:
-36
Step-by-step explanation:
le x be 2 then
f(x) = -2-2 =-4
g(x)= 2square +1-2 =3
to find:(f×g)(3)
(-4×3)(3)
=-36
Answer:
It’s a graph and we can’t help you but you can plug the equations into desmos (an online graphing calculator) to generate a line
