Answer:

  10%

Step-by-step explanation:

Using the given formula with the given data, we have ...

  efficiency = output work / input work

  = (10 J)/(100 J) = 0.10 = 10%

The volume of water remaining in a hot tub when it is being drained satisfies the differential equation dV/dt = −3(V)^1/2 , wher
dimaraw [331]
The given function is a variable separable differential equation. Combine like terms, integrate, apply the appropriate limits, and express V in terms of t. This is done as follows:

dV/dt = -3(V)^1/2
dV/-3V^1/2 = dt
\int\limits^V_m { \frac{1}{03 \sqrt{V} } } \, dV = \int\limits^t_0 {} \, dt

m here is the initial V which is 225. Then after integrating,

-2/3 (√V - √225) = t
-2/3 (√V - 15) = t

V= \sqrt{ \frac{-3}{2}t+15 }

That is the expression for V at time t. I hope I was able to help. Have a good day.

If f(x) = 2x2 + 1 and g(x) = x2 – 7, find (f – g)(x).
nadya68 [22]

Answer:  The required value is

(f-g)(x)=x^2+8.

Step-by-step explanation: The given functions are:

f(x)=2x^2+1,\\\\g(x)=x^2-7.

We are given to find the value of (f-g)(x).

We know that, if s(x) and t(x) are any two functions of a variable x, then we have

(s-t)(x)=s(x)-t(x).

Therefore, we have

(f-g)(x)\\\\=f(x)-g(x)\\\\=(2x^2+1)-(x^2-7)\\\\=2x^2+1-x^2+7\\\\=x^2+8.

Thus, the required value is

(f-g)(x)=x^2+8.

A spinner numbered 1 through 5 is spun 3 times. what is the probability of spinning a number less than 3 each time? are these ev
olya-2409 [2.1K]
Prob(spinning a number < 3on 1 spin)  = Prob( spinning 1 or 2) = 2/5

Prob( spinning <3 3 times) =  2/5 * 2/5 * 2/5  = 8/125

These events are independent so we multiply the probabilities.
