Answer:
The Answer is -2
Step-by-step explanation:
Given f(x) = -2
and g(x)= x-3
Now fog(x) is a composite function
i.e. A function that depends on another function
Here domain of f(x) is g(x)
i.e. g(x) is substituted in place of x
i.e. we substitute x with x-3
So f(g(x))
=f(x-3)
= -2
If Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail then the efficiency of the hammer is 70%
<h3>What is efficiency ?</h3>
Efficiency is the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
Given that Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail.
Efficiency of hammer can be calculated as
efficiency = output obtained / input given
E=105/150
E=7/10
E=0.7
Converting into percentage
If Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail then the efficiency of the hammer is 70%

Following order of operations:
3^2 = 9
(10-2) = 8
Now you have :
9 + 8 x 5 -4
Multiplication is next:
9 + 40 -4
Now just add and subtract from left to right:
9 + 40 = 49
49-4 = 45
The answer is 45
C: the third one
Step-by-step explanation:
Answer: is smaller than .
Step-by-step explanation:
- Find the least common denominator or LCM of the two denominators:LCM of 3 and 10 is 30
- For the 1st fraction, since 3 × 10 = 30,
- <em><u>Likewise, for the 2nd fraction, since 10 × 3 = 30,</u></em>
- <u><em>Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction</em></u>
