Answer:
Step-by-step explanation:
A
A will give you the roots (the x intercepts) just by reading the numbers and doing a small adjustment.
x + 1 = 0
x = - 1 So one of the roots is (-1,0)
x + 5= 0
x = - 5 The other root is (-5,0)
A is not the answer.
B
I have graphed B so that you can see that A is true. See below, Even so, B is in standard form and it is not the answer.
C
The answer is C. The vertex is at 2,27
x - 2 = 0
x = 2
The maximum value is located at 27 which is just read.
That point (2,27) is plotted on the graph.
Explanation
We are given the following right-angled triangle:
We are required to determine the indicated angle in the given figure.
This is achieved thus:
According to the image, we have:
Therefore, we have:
Hence, the answer is:
