Answer:
The y-intercept is (0,-6), the vertex is (4,2)
Step-by-step explanation:
Answer:
y = √55
Step-by-step explanation:
All the triangles are similar, so the ratio of short side to hypotenuse is the same for all:
5/y = y/(5+6)
y^2 = 55
y = √55
_____
<em>Comment on the geometry</em>
There are three "geometric mean" relationships that apply to this geometry.
- the altitude BD is the geometric mean of BC and BA (√30)
- the long side of the large triangle is the geometric mean of the longer segment of the hypotenuse and the whole hypotenuse (x = √66)
- the short side of the large triangle is the geometric mean of the shorter segment of the hypotenuse and the whole hypotenuse (y = √55)
If you were aware of the last of these relationships, you could write down the answer without any "work."
y = √(5(5 +6)) = √55
__
The geometric mean is the n-th root of the product of n numbers. When there are 2 numbers, it is the square root of their product.
An equivalent statement is CD overbar congruent to EF overbar.
What is a line segment?
The line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.
Here,
Line segment CD is congruent to line segment EF and in geometry, an overbar represents a line segment.
So, we can say that the CD overbar means line segment CD and the EF overbar means line segment EF.
Hence, An equivalent statement is CD overbar congruent to EF overbar.

Responda:
48,5
Explicação passo a passo:
Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5
