Answer:
C
Step-by-step explanation:
Formula:
d = √(x2−x1)^2 + (y2−y1)^2
plug in
d = √(8−2)^2 + (5−2)^2
d = √(6)^2 + (3)^2
d = √36 + 9
d = √45
This equation is in vertex form. Vertex form is y=a(x-h)^2+k, where (h,k) is the vertex. In this equation, h= -3, and k= -4. So, the vertex would be at (-3,-4). A tells us if the parabola will be positive or negative. In this case, it is positive, so the parabola opens upward. Then, you can solve for x-intercept by letting y=0 and solving for x. Then, you can find the y-intercept by setting x=0 and solving for y. Finally, graph the parabola.
Answer:
Exterior Angle = 36 degrees
Step-by-step explanation:
<u><em>Each interior angle of a regular decagon measures 144 degrees.</em></u>
=> <u><em>We'll subtract 144 from 180 to get the measure of the exterior angle.</em></u>
=> Exterior Angle = 180-144
=> Exterior Angle = 36 degrees
If this is in science terms its a plain if this is in mathematical terms, the answer is the number 0 anything below is negative, anything abouve is pos
