Answer:

$Nick's\ earning=\$ 176.25$

Step-by-step explanation:

Let total meal served $=\$x$

$Tip=15\%\ of x=\frac{15}{100}x=0.15x\\\\Nick's\ earning=75+0.15x\\\\Here\ x=\$675\\\\Nick's\ earning=75+0.15\times 675=75+101.25=\$ 176.25$

Your answer is D.
Because there are no negative reciprocals, therefore there are no right angles.

Find the equation of a circle with a center at (7,2) and a point on the circle at (2,5)?

monitta

Answer:

$(x-7)^2+(y-2)^2=34$

Step-by-step explanation:

We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).

First, recall that the equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

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

Since our center is at (7, 2), h = 7 and k = 2. Substitute:

$(x-7)^2+(y-2)^2=r^2$

Next, the since a point on the circle is (2, 5), y = 5 when x = 2. Substitute:

$(2-7)^2+(5-2)^2=r^2$

Solve for r:

$(-5)^2+(3)^2=r^2$

Simplify. Thus:

$25+9=r^2$

Finally, add:

$r^2=34$

We don't need to take the square root of both sides, as we will have the square it again anyways.

Therefore, our equation is:

$(x-7)^2+(y-2)^2=34$
