Step-by-step explanation:
5^2 + b^2 = 9^2
25 + b^2 = 81
b^2 = 56
square root both sides and b = 7.48 cm
Hope this helps, if not sorry.
Your answer should be -8y + 6.6z + 10
The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
We are given
Ronaldo delivers the papers at the rate of 6 papers in 24 minutes
so, number of papers =6 in time =24 minutes
so, firstly we can find rate
rate = ( number of papers)/( time taken)

now, we can find times
Time for 56 papers:
we are given
number of papers =56
rate is

now, we can find time



Time for 41 papers:
we are given
number of papers =41
rate is

now, we can find time



now, we can find time difference

so, we can plug values
