Signs are placed at the beginning and at the end of a 4-kilometer hiking trail. Signs are also placed every 500 meters along th

il63 [147K]

Answer:

9 Signs

Step-by-step explanation:

The hiking trail is 4 kilometer long.

Signs are placed at the beginning and at the end of the trail.

4km = 4000m

We can solve this using simple arithmetic progression.

The first term,a= 0
The common difference,d= 500.
The last term,l= 4000.

Therefore:

Last term, l=a+(n-1)d

4000=0+500(n-1)

4000=500n-500

4000+500=500n

4500=500n

Divide both sides by 500

n=9

Therefore, there are a total of 9 signs on the entire trail.

CHECK

The signs are placed at this marks

0m,500m,1000m,1500m,2000m,2500m,3000m,3500m and 4000m

Find the equation of the median shown:

qwelly [4]

Hey there! I'm happy to help!

The median is the line cutting the triangle in this graph. In general, a median connects any of the triangle points to halfway across the side opposite to that point. This median connects R to halfway across the side across from R.

We want to find the equation of this median. We see that T is at (-2,3) and R is (3,-3). The first thing to do when looking for the equation of the line is to find the slope, or incline. Since we have two points, we can do this very easily. You simply divide the difference in the y-values by the difference in the x-values.

DIFFERENCE IN Y-VALUES

3-(-3)

3+3

DIFFERENCE IN X-VALUES

-2-3

-5

Now, we divide the two answers, giving us -6/5.

So, we have our slope, which gives us the equation so far y=-6/5x+b. We just need to find the b, which is our y-intercept. Well, to do this, we plug in one of our points and we can solve for b. We will use (3,-3)!

-3=-6/5(3)+b

-3=-3 3/5+b

We add 3 3/5 to both sides to isolate the b.

b=3/5

This means that this median should hit the y-axis at (0,3/5), and it looks like it does. Therefore, the equation of this median is y=-6/5x+3/5.

Now you can find the slope of a median! Have a wonderful day! :D

Find the zeros of the function in the interval (-2 pie, 2 pie). f(x) = 3 cos x

Fantom [35]

Answer:

Roots are -π/2 and π/2

Step-by-step explanation:

${ \bf{f(x) = 3 \cos(x) }}$

when x is -2π:

${ \sf{f( - 2\pi) = 3 \cos( - 2\pi) }} \\ { \sf{ = 3}}$

hence -2π is not a zero of the function

when x is 2π:

${ \sf{f(2\pi) = 3 \cos(2\pi) }} \\ { \sf{ = 3}}$

hence 2π is not a zero of the function

when x is π/2:

${ \sf{f( \frac{\pi}{2}) = 3 \cos( \frac{\pi}{2} ) }} \\ { \sf{ = 0}}$

Hence ±π/2 is the zero of the function.
