Answer:

k = 1.5

Step-by-step explanation:

In order to isolate your variable, k, you need to do inverse operations. Since k is being multiplied by 78, you want to divide both side by 78.

k x 78 = 117

k x 78/78 = 117/78

k x 1 = 1.5

k = 1.5

Answer:

\boxed{\sf x= -29.5}

Step-by-step explanation:

\sf \sqrt{-2x+5}-3=5

\sf \sqrt{-2x+5}=8

\sf -2x+5=64

\sf -2x=59

\sf \cfrac{-2x}{-2}=\cfrac{59}{-2}

Therefore, x = -29.5.

What is the height of spanning tree obtained from Wn by the breadth-first search, starting at the central vertex of Wn?
Alex73 [517]

Answer:

The height of the spanning tree is one by the breadth-first search at the central vertex of Wn.

Step-by-step explanation:

The graph is connected and has a spanning tree where the tree can build using a depth-first search of the graph. Start with chosen vertex, the graph as the root, and root add vertices and edges such as each new edge is incident with vertex and vertices are not in path. If all vertices are included, it will do otherwise, move back to the next level vertex and start passing. It is for depth-first search. For breadth-first search, start with chosen vertex add all edges incident to a vertex. The new vertex is added and becomes the vertices at level 1 in the spanning tree, and each vertex at level 1 adds each edge incident to vertex and other vertex connected to the edge of the tree as long as it does not produce.

A toy rocket is launched from a platform 24ft above the ground. The
jok3333 [9.3K]

Answer:

4 sec

Step-by-step explanation:

let y = 0 which is the height when the rocket hits the ground

-3t^2 + 6t + 24 = 0

-3(t^2 - 2t - 8) = 0

-3(t - 4)(t + 2) = 0

t = 4  or t = -2

time cannot be negative, so t = 4 sec
