Answer:
Vertex: (-2, 0)
Axis of symmetry: x = -2
Direction of opening: Upwards
Min: 0
Y-intercept: 4
Step-by-step explanation:
Let us graph this line, and then pull out the details we need. <em>See attached</em>.
What do all of these different things mean?
<u>Vertex:</u> This is where the graph intercepts the axis of symmetry (x = -2, see below) and is at point (-2, 0) for this graph.
<u>Axis of Symmetry:</u> This is the line that the graph is symmetrical across. The "center" of the graph. Here, it is x = -2.
<u>Direction of Opening:</u> The direction that the graph is going/opening towards. In this case, it is upwards.
<u>Min:</u> The minimum (in this case) value, the lowest y-coordinate. This is 0 here.
<u>Y-intercept:</u> The point at which the line intercepts the y-axis. This is 4 here.
Step-by-step explanation:
From your problem statement, I believe the equation will look like this:
The slash means "divided by" -- you should use division to solve this equation.
For division involving exponents with the same base, you can use the following rule:
Subtituting for
,
for
and
for
, we get the following:
Answer:
104.127 m
Step-by-step explanation
In the question instead of chi, it would be kite.
Given: Distance of Brooke from the base of tree is 50 meters.
The kite is directly above the 10 m tree in the 125 m string is fully extended.
Lets assume the height of the kite be "x".
Its making the Right angle triangle with length of string as hypotenuse, height of kite above tree.
Using Pythagorean formula:
h²= a²+b²
⇒
⇒
⇒
Subtracting both side by 2500
⇒
Square rooting both side, we know√a²=a
⇒
∴ x= 114.127 meter.
Next, we know the value of x include the height of tree.
∴ Height of kite flying above tree=
⇒ Height of kite flying above tree=
Hence, the height of kite above the tree is 104.127 meters.
