Answer:

Step-by-step explanation:

The graph passes through the origin. It could either open up or open down. The quadratic has two zeros, both at (0, 0).

If it is the same as the Y- intercept, then that makes the quadratic function equal. The line passes through the origin ( 0,0 ).

How do you graph 193 + y is greater than or equal to 201

Travka [436]

Answer:

The correct answer is y ≥ 8

Step-by-step explanation:

In order to graph this, we must first solve the equation for y.

193 + y ≥ 201

y ≥ 8

Now that we have the solved version, we can graph on a number line. Draw a closed circle on the point 8 and then draw an arrow to the right to show that it is greater.

5. A monument casts a 78 ft. shadow at the same time that a vertical yardstick casts a 4.5 ft. shadow. How high is the monument?

rodikova [14]

Hello,

Using Thalès 's theorem:

Let's h the height of the monument.

$\dfrac{1}{h} =\dfrac{4.5}{78} \\\\h=\dfrac{78}{4.5} =\dfrac{156}{9} \approx{17.3\ (ft)}$

If you don't know what is the Thalès's theorem,

imagine that the similar triangles.
