Which description of the graph of y=110x is most accurate?
hodyreva [135]

Answer:

The correct option is;

The graph is a line that rises steeply from left to right and passes through the origin

Step-by-step explanation:

The given equation is y = 110·x

Comparing the given equation to the general equation of a straight line, y = m·x + c

Where;

m = The slope of the straight line graph

c = The y-intercept

We have;

The slope of the given equation, y = 110·x = 110

The y-intercept, which is given by the constant c in the given equation = (0, 0)

Therefore, by the slope of the equation, for each unit increase in x, y increases by 110, therefore, the graph is a straight line that rises steeply and passes through the origin

Sarah walks 20 feet away from her house and places a mirror on the ground. She backs 5 feet away from the mirror so that she can
Vikki [24]

Answer:

16 feet

Step-by-step explanation:

As said in the problem statement, the angles between the top of the house, the mirror, and the ground and between Sarah's eyes, the mirror, and the ground are congruent.

We also know that Sarah and the house are perpendicular to the ground.

So if we draw a triangle from the top of the house, to the mirror, to the bottom of the house, and another triangle from Sarah's eyes, to the mirror, to Sarah's feet, we get two triangles that have the same angles.  Therefore, the triangles are similar, and we can write a proportion:

4 / 5 = h / 20

h = 16

The house is 16 feet tall.

Who was Radius helping when he discovered that the "magic number was more than 3"?
Strike441 [17]

Answer:

Radius was helping his father Sir Cumference.

Explanation:

The question above is related to the mathematical adventure story entitled <em>"Sir Cumference and the Dragon of Pi."</em>

Radius was the<u> son of Sir Cumference and Lady Di of Ameter</u>. One day, Sir Cumference drank a potion which turned him into a dragon. In order to restore his father's shape, radius needed to find the magic number called "pi."  

In mathematics, the value of pie is more than 3<em> (3.14 to be exact)</em> and it is represented by the Greek symbol "\pi."

So, this explains the answer.
