Answer:
Therefore,
Step-by-step explanation:
Given:
GF = 12
GE = 16
DF = 12
CF = v
To Find:
v = ?
Solution:
In Δ GFC and Δ GED
∠ E ≅ ∠ F …………..{ measure of each angle is 90° given }
∠ G ≅ ∠ G ……….....{Reflexive Property}
Δ GFC ~ Δ GED ….{Angle-Angle Similarity test}
If two triangles are similar then their sides are in proportion.
On substituting the given values we get
Therefore,
Answer:
Step-by-step explanation:
we have that
Using a graph tool
see the attached figure
The function represent a vertical parabola that open up
the vertex is a minimum-------> is the point (-0.5, -9.3)
The x-intercepts are the points when the y coordinate is equal to zero
The x-intercepts are the points (-3.5, 0) and (2.5, 0)
so
the function cross the negative x-axis at point
therefore, the answer is
(-4, 0) and (-3, 0)
