Answer: The length of flagpole is 24 feet.
Step-by-step explanation:
Since we have given that
Length of shadow =40 feet
Angle of elevation to the sun =
In ΔABC,
We can apply "trigonometric rules ",
Hence, the length of flagpole is 24 feet.
The total number of books is the sum of the chapter books and picture books, 11+7 =18
Thus 18 is the total number of books
If she gave away 1/3 of the books, 6 books were given away as 1/3 of 18 is 6
=> Ella gave 6 books to her cousin
The statements about the function that are true are
- The vertex of the function is at (–3,–16).
- The graph is increasing on the interval x > –3.
- The graph is positive only on the intervals where x < –7 and where x > 1.
<h3>How to interpret the graph?</h3>
The equation of the graph is given as
f(x) = (x - 1)(x + 7)
The graph of the function is added as an attachment
On the graph, we have
Vertex = (-3, -16)
This is so because the graph has a minimum point of (-3, -16)
Also, the graph crosses the x-axis at x = 1 and x = -7
This means that the graph is positive at x >1 and x >-7
Because the vertex is a minimum, the graph is increasing at the left of its symmetry i.e. x > -3
