Answer:
Step-by-step explanation:
The standard vertex form of a quadratic (which is what your graphs are) is
where h and are the coordinates of the vertex. The vertex is really all we need to fill in this equation. Looking at the blue graph, the vertex is located at (-4, 1), so h = -4 and k = 1. Filling in the equation:
which simplifies down to
. It's that simple.I think that's choice C (I'm not sure; it's very tiny!)
Can you give me some hint please
The height of the tree based on the information is 229.23.
<h3>How to calculate the height?</h3>
Based on the information given,
tan 50 = h/x + 60
h = (x + 60)tan 50°
x tan 60 = (x + 60)tan 50°
x(tan 60° - ta 50°) = 60 ta 60
x = 132.34
Therefore, the height will be:
= x tan60°
= 132.34 × tan 60
= 229.23
Therefore, the height is 229.23.

Yes, f(x) = 16 - 7x is a linear function because there are no exponents and the rate of change (which is the slope) only adds or subtracts a certain number each time.
Answer:
no as all fractions are rational numbers and that is a mixed fraction
