(18.6 + 9.4) x 1/2^2= 7 hope it helps!
For, f(1) = 2-3x =2-3 =-1
and, for, g(1) = | 2-3x | =| -1 | = 1 (The symbol | | determines the abstract value i.e, positive value)
Answer: work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
Step-by-step explanation:
We know that
f(x) = kx
given that;
Natural length L = 5
x = 8.4 - 5 = 3.4
force F = 4.0 lb
f(x) = kx
we substitute
4 = k × 3.4
k = 4 / 3.4
k = 1.1764 = 20/17
Now work done from natural length to 12.8
x = 12.8 - 5 = 7.8
work done = ₀∫^7.8 f(x) dx
= ₀∫^7.8 kx dx
we substitute value of k
= ₀∫^7.8 (20/17)x dx
= 20/17 [ x²/2 ]
= 20/17 [ (7.8)²/2 - 0 ]
= 1.1764 × 30.42
= 35.786 ≈ 36 lb.In
Therefore work is done in stretching it from 5.0in. to a length of 12.8in is 36 lb.In
40 hours * 52 weeks = 2080 hours total worked that year.
2080 hours * 25.21 paycheck = 52,436.80
In reality you would have to subtract out holidays, any vacation, any sick days and taxes. All of that information varies by location and company.
-10 divided by -2/5
The answer is 25 to it works because the quotient is greater than 10.
Remember that when dividing by a fraction you gotta flip the second fraction and then multiply.
So -10/1 divided by -2/5 turns into
-10/1 x 5/-2
-50 / -2 = 25
