Vertex form uses the following formula:
Identify the values of h and k in your function:
The vertex is found with the following point:
The vertex will be found at
(-5, -28).
<span>= -4 ≥ 10 − 7x [ changed 4 to -4 on the request of questioner ]
Subtract 10 from both sides,
= -4 - 10 </span>≥ -7x + 10 - 10
= -14 ≥ -7x
Divide both sides from -7,
= -14/-7 ≤ -7x/-7 [ sign changed as we use "-" here ]
= x ≥ 2
In short, Your Answer would be x ≥ 2 which is Option C
Hope this helps!
Answer:
The shadow length is 125 inches.
Step-by-step explanation:
The triangle that the sun's rays and the fence post form is shown in the figure.
From trigonometry we know that 
is the ratio of the opposite <em>(72-in fence)</em> to the adjacent side 
of the triangle <em>(the shadow length): </em>
<em />
<em />
since
<em />
<em />
we have
<em />
<em />
solving for we get:
Hence, the length of the shadow to the nearest inch is 125 inches.
This is a Linear sorry if I’m wrong
