A6.0 cm high elevation block is placed under one end of a 1.0 m long track. find the angle of elevation of the track.

3.4°

Step-by-step explanation:

A 6.0 cm high elevation block is placed under one end of a 1.0 m long track.

Block is 6 cm high. It would stand vertically.

Stand one end of horizontal track 1 m long.

Please see the attachment for graph.

Let the elevation of block is Ф

In ΔABC, ∠B=90°

AB= 6 cm

BC = 1 m

First we change meter to centimeter. 1 m = 100 cm

So, BC = 100 cm

Hence, The elevation of the track is 3.4°

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
