I am not entirely sure what your asking but i think you mean which will coast the least and that would be 8 since it’s the smallest amount
So the first one is (7x)^(1/2) or square root of 7x minus - 5 square root all squared so
([7x^(1/2)]-[5^(1/2)]) times ([7x^(1/2)]-[5^(1/2)])
or 7x-(35x^(1/2))-5+(35x^(1/2)) or 7x-5
number 2
since 11 is 1/2 of 22 it can be written as
the square root of 3 or 3^(1/2)
The answer would be D.
Curve of the function can't be cut by vertical line more than once at different points.
Solve for a.
y=2x/a+2b
Multiply both sides by a.
ay=2ab+2x
Add -2ab to both sides.
ay+−2ab=2ab+2x+−2ab
−2ab+ay=2x
Factor out variable a.
a(−2b+y)=2x
Divide both sides by -2b+y.
a(−2b+y) / −2b+y = 2x / −2b+y
a = 2x / −2b+y
The force for the case 1 is 64 pounds and the distance is 9 feet, it is:
Now, if the force is 36 pounds, let solve for the distance:
Hence the answer is 12 feet.
