The geometry technique that Chee uses to find the height of the goalpost is the equal ratio of the corresponding sides of similar triangles.

Correct response:

  • The eight of the goalpost is approximately <u>16.91 meters</u>.

<h3>Methods used to calculate the height</h3>

The length Chee is using the mirror to measure = The height of her school's football goalpost

The distance of the mirror from the goalpost = 14.35 meters

The distance on the other side of the mirror Chee steps to =  1.4 meters

The distance from her eyes to the ground = 1.65 meters

Required:

How tall is the goalpost.

Solution:

By using similar triangles relationships, we have;

\dfrac{1.65}{1.4} = \mathbf{\dfrac{Height \ of \ the \ goalpost, h}{14.35} }

Which gives;

h = \dfrac{1.65}{1.4} \times 14.35 = 16.9125 \approx \mathbf{ 16.91}

  • The height of the goalpost, h ≈ <u>16.91 meters</u>

The sum of -3 times a number and 0.3 is at most 6.3. What are all the possible
densk [106]

Answer:

Step-by-step explanation:

Lets write an equation for this :)

So, the sum of -3 times a number and 0.3

This would be : -3x +0.3

Is at most, 6.3

so, it is equal to, or less than 6.3

-3x +0.3 <u><</u> 6.3

Now lets solve!

x<u>> </u>-2

the number is greater than or equal to -2

sattari [20]
ANSWER

All real numbers greater or equal to -3.


EXPLANATION

The domain of the given function are values of x that make the function defined.


We can see from the graph that, the domain are x-values greater than or equal to -3.



In other words, we can find a corresponding y-value for all x-values greater than or equal to -3.

The correct answer is option D.
