Answer:
y = x^2 - 2x - 8
Step-by-step explanation:
First we can put it into vertex form, the vertex is at (1, -9)
y = a ( x − h )^2 + k .
y = 1 (x - 1)^2 - 9
Then distribute:
y = x^2 - 2x + 1 - 9
y = x^2 - 2x - 8
Answer:
A. Both triangles contain right angles and a corresponding angle of equal measure. Thus, two angles of the large triangle are equal in measure to two angles of the small triangle
x = 3 m
Step-by-step explanation:
The figure given shows two right angles triangles having corresponding angles that are congruent and of the same measure.
If we find the ratios of their given corresponding side lengths, their ratios would be the same.
Thus: ratio of the side of the smaller ∆ to the larger ∆ = 4:8 = 5:10 = 4/8 = 5/10 = ½
½ is the scale factor. Therefore, both triangles are similar.
To find x, multiply the corresponding side length of the other triangle by the scale factor.
x corresponds to side length that is 6 m in the other triangle.
Therefore,
x = 6*½ = 3 m
