<u>We are given:</u>

a right angled triangle with the angle of elevation = 20 degrees

Hypotenuse of the Triangle = 500 m

<u>Finding the change in Elevation:</u>

We will use trigonometry in the given triangle to find the length of the perpendicular of the triangle

Using trigonometry, we found that the perpendicular = 500 * Sin 20 degrees

Perpendicular = 500 * 0.342           <em>[sin(20 degrees) = 0.342]</em>

Perpendicular = 171 m

The closest value to 171m in the given options is 170m

Therefore, 170m <em>(option B)</em> is correct

Doctor better than teacher debate<br>​
Jet001 [13]

Answer:

A doctor sees more different patients each year than a teacher sees different students. The doctor can affect those people in ways that are much more personal and have much more of an immediate impact on their life.

After all, these specialists have knowledge and skills to diagnose, treat, and control the course of various diseases. Doctors save our lives.A teacher is better because he/she gives you the first advice on what to do and a doctor follows. Teachers are more knowledgeable than doctors. A teacher has knowledge about politicians, nurses and other professions yet doctors only treat patient. a teacher They encourage students to understand the importance of dedicating themselves to passion projects or endeavors. And success builds upon success. The more a student pushes themselves to accomplish their goals, the more they realize what they are capable of doing.

The equation(function):10.00+.75x
valentinak56 [21]

Answer:

Answer:

b. -75x+57=-75x+57

Step-by-step explanation:

If an equation after solving does not give the solution but give a true statement then the equation has infinitely many solution,

In option a.

57x+57=-75x-75

57x + 75x = -75 - 57

132x = -132

⇒ x = -1

i.e. it has only one solution,

In option b.

-75x+57=-75x+57

-75x + 75x = 57 - 57

0 = 0  ( True )

i.e. it has infinitely many solution.

In option c.

75x+57=-75x+57

75x + 75x = 57 - 57

150x = 0

⇒ x = 0

i.e. it has only one solution,

In option d.

-57x+57=-75x+75

-57x + 75x = 75 - 57

18x = 18

⇒ x = 1

i.e. it has only one solution.

What is the rate of change shown in the graph
ahrayia [7]

Answer:

-4/3  (Answer A)

Step-by-step explanation:

Here we go from the point (-3, 3) on the left to the point (0, -1) on the right.  It is immediately apparent that x (the run) increases by 3 from -3 to 0 and that y (the rise) decreases by 4 from 3 to -1.  Thus, the slope of this line (which is also the rate of change) is

m = rise / run = -4/3  (Answer A)
