Step-by-step explanation:

I can give you the formulas and how to do it.

The formula for finding the slope is

y²-y¹ all over(divided by) x²-x¹.

You take the order pairs and you label them.

For example, the first one.

(4,2) 4 can be x¹ and 2 can be y¹

(7,6.5) 7 can be x² and 6.5 can be y²

So then you plug it in.

(6.5-2) all over/divided by (7-4)

That ends up being 4.5 over 3. Fraction form.

That is your slope.

Then you plug the slope into the point-slope formula which is

y-y¹=M(x-x¹).

You plug your slope in for M.

You pick either of the given points and plug it in for y¹ and x¹.

Then you solve.

If done right, your formula will end up matching the slope-intercept formula

y=Mx+b.

M is your slope.

b is your y-intercept.

Dont freak out when you start doing it with fractions. Just because it looks wierd, doesnt mean it's wrong.

Use this process for all four.

Hope this helps.

Chris & Maya are looking at three companies in the motorbike industry- Honda, Hero & Yamaha. They identified three stren

luda_lava [24]

Answer:

1/ Zamaha

2/ Hero

3/ Honda

Step-by-step explanation:

unweighted method is used which means the 3 mearsure are accounted for the same poportion in competitive strength assesment, 1/3 for each criteria.

So, we caculate the avergae points of each brand;

Honda = 1/3*(7+5+8) = 20/3
Hero = 1/3*(8+6+7) = 21/3
Zamaha = 1/3*(6+8+9) = 23/3

The order of the companies from highest to lowest is:

1/ Zamaha

2/ Hero

3/ Honda

Given cosine of x is equal to negative square root of 3 over 2 comma what is the value of cos(x π)?

slamgirl [31]

Value of cos(x+π) = $\bold{\frac{\sqrt{3} }{2}}$

Given cosine of x = $-\frac{\sqrt{3} }{2}$

i.e., cos(x) = $-\frac{\sqrt{3} }{2}$

Also cos( $\frac{\pi}{6}$ ) = $\frac{\sqrt{3} }{2}$ . So x = $\frac{\pi}{6}$ .

We need to find cos(x+π) = cos( $\frac{7\pi}{6}$ ).

But its value is not easy to find. So we use trigonometric formulas.

We have the trigonometric formula, cos (x+π) = - cos(x) = - $-\frac{\sqrt{3} }{2}$ = $\bold{\frac{\sqrt{3} }{2}}$

Cos(x+π) lies in the 3rd quadrant. So there cosine has negative values. That is why, cos (x+π) = - cos(x).

If a train traveled at 50 meters within 120 seconds, what is its speed?

Alja [10]

Answer:

v = 0.416 m/s

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

$v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s$

So, the speed of a train is 0.416 m/s.
