Answer: 9/8
Step-by-step explanation:
- Vertex form: , with (h,k) as the vertex.
For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:
Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:
Putting our equation together,<u> it's </u>
<u>*Additional section*</u>
- Standard form:
Converting to standard form as such:
Answer:
21
Step-by-step explanation:
47.67 divided by 2.27 = 21
Given:
In the given triangle,
With respect to y, Perpendicular = 10 cm and Base = 8 cm
To find the value of y.
Formula
By Trigonometric Ratio we get,
Now,
Putting the values of perpendicular and base we get,
or,
or,
Rounding off to the nearest tenth, we have;
Hence,
The value of y is 51.3°.
We can write a proportion: 15 m is to 12 m as some other height
is to 20 m
So we get
So the second tree is 25 m tall.
