If f(x)=3(x+5)+4/x what is f(a+2) ?

1 answer:

7 0

$f(x)=3(x+5)+\dfrac{4}{x}\\\\f(a+2)\to\text{put x = a + 2 to the equation of the function f}\\\\f(a+2)=3(a+2+5)+\dfrac{4}{a+2}=3(a+7)+\dfrac{4}{a+2}$

Setup
45t = 40t + 60
5t = 60
t = 12

car A = 45 * 12 = 540 mi
car B = 40 * 12 = 480 mi

The correct order for bisecting angle ABC is F D E B C A. Option D

<h3>Steps in bisecting angles</h3>

The steps involved in bisecting angles are;

Place compass point on the vertex of the angle (point B).
Stretch the compass to any length that will stay OF the angle
Swing an arc so the pencil crosses both sides (rays) of the given angle. You should now have two intersection points with the sides (rays) of the angle
Place the compass point on one of these new intersection points on the sides of the angle. Stretch the compass to a sufficient length to place your pencil well into the interior of the angle, this should be within the rays of the angle
Place an arc in this interior
Without changing the span on the compass, place the point of the compass on the other intersection point on the side of the angle and make a similar arc. The two small arcs in the interior of the angle should be intersecting
Connect the vertex of the angle (point B) to this intersection of the two small arcs

From the listed steps, the correct order for bisecting angle ABC is F D E B C A. Option D
