Answer:
C. Hyperbola opening up and down
Step-by-step explanation:
A graph tells the tale.
___
The term with the positive coefficient identifies the axis along which the hyperbola opens. Here, that is the y-axis, so the figure opens up and down.
The minus sign between the squared terms indicates it is a hyperbola, rather than a closed curve (ellipse or circle). The fact that both terms are squared indicates it is <em>not</em> a parabola.
Hi there!
From what I know, when you multiply one number in a ratio, you must also multiply the other number by the same number. This allows for the ratio to stay the same, thus keeping it correct. If both terms were not multiplied by n, the ratio would no longer be the correct ratio.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Just ask some one else this is to much u should know this u are really smart and i belive in u
Answer:
59.38 ft
Step-by-step explanation:
The person and his shadow form a triangle. The tree and its shadow also form a triangle. The triangles are similar triangles, so the lengths of corresponding sides are proportional.
Let the unknown tree height be h.
(person's height)/(person's shadow) = (tree height)/(tree's shadow)
(75 in.)/(48 in.) = h/(38 ft)
(25)/(16) = h/(38 ft)
16h = 25 * 38 ft
16h = 950 ft
h = 59.375 ft
h = 59.38 ft
The Answer is <em>C </em>
