100000+200000=300000
28x=300000
X=10714
They would need to make $10714 a night
4n - 3= -2n + 9
add 3n to both sides
4n= -2n +12
add 2n to both sides
6n= 12
divide both sides by 6
n= 2
Check:
4n-3=-2n+9
4(2)-3= -2(2)+9
8-3= -4+9
5=5
Hope this helps! :)
A=22/10
A=integral(a,b) [f(x)-g(x)]dx
Since the function is even (the function is mirrored over the y axis) we can evaluate the integral from 0 to 1 and then multiply our answer by 2 since we have the same area on each side of the y axis.
We get A=2*int.(0, 1)[(x^2)-(-2x^4)]dx
Now we can integrate by term.
2*[int.(0, 1)[x^2]dx+int(0, 1)[2x^4]dx]
Now factor out constants.
2*[int(0,1)[x^2]dx+2int(0,1)[x^4]dx]
Now integrate.
2*[(x^3/3)|(0,1) + 2*(x^5/5)|(0,1)]
Now solve.
2*[(1/3)+2*(1/5)]
=22/10

√16 / √100
= 4 / 10
= 2 / 5
Answer:
156.5375 cm
Step-by-step explanation:
The function used to estimate the height is F(x)
F(x) = 2.75x + 71.48
The humerus is xcm long. When x = 30.93cm, we put x = 30.93 into the function F(x)
F(30.93) = 2.75(30.93) + 71.48
= 85.0575 + 71.48
= 156.5375 cm(4 decimal places)
