Can someone me with this question

(x−4)² + (y−5)² = 36

Step-by-step explanation:

The equation of a circle is:

(x−h)² + (y−k)² = r²

where (h, k) is the center and r is the radius.

If the center is (4, 5) and the radius is 6, then the equation is:

(x−4)² + (y−5)² = 6²

(x−4)² + (y−5)² = 36

The mechanical advantage of the hammer is 4.

Step-by-step explanation:

We know that the mechanical advantage of the hammer is is given by the ratio between the force applied on the hammer and the force required to overcome the given force.

Force applied = 40 N

Force required= 160 N

Mechanical advantage =

Mechanical advantage =

Hence, the mechanical advantage of the hammer is 4.
