V = s/t ⇒ s = vt

25 mi/h · th + 45 mi/h · mh = 25mi · t + 45mi · m = (25t + 45m)mi

Answer: The expression represent the distance that car traveled.

Answer: The expression represent the distance that car traveled.

Velocity= Speed/Time meaning that Speed= Velocity x Time

(25 miles per hour x t hours ) + (45 miles per hour x m hours)= 25 miles x t +45 miles x m= (25t + 45m) miles

(25t + 45m) miles

The expression above represents the distance that the car travelled.

Standard equation of circle with center of (6,8) that passes through point (-1,4)

dezoksy [38]

Answer:

The result should be:

$(x-6)^2+(y-8)^2=\sqrt{65}$

Step-by-step explanation:

-The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$ where the center is $(h,k)$ , the point $(x,y)$ and the radius known as $r$ .

-Use the center (6,8) and the point (-1,4) for this equation:

$(-1-6)^2+(4-8)^2=r^2$

-Then, you solve for the radius and get the equation:

$(-1-6)^2+(4-8)^2=r^2$

$(-7)^2+(-4)^2 =r^2$

$49 + 16 = r^2$

$65 = r^2$

$\sqrt{65} =\sqrt{r^2}$

$\sqrt{65} = r$

-Result:

$(x-6)^2+(y-8)^2=\sqrt{65}$
