Hello!

To find the slope, we use the following formula:

m= $\frac{y2-y1}{x2-x1} \\\frac{4-4}{7-5}$

m= $\frac{0}{2} \\0$

Keep in mind that if the y-coordinates are the same, then the slope is 0.

That's because if the y-coordinates are the same, then the line is horizontal and the rise (how many units we rise up) is 0 units.

Therefore, the slope is: 0.

Hope this helps you!

Answer:

$\implies \dfrac{ -4x+7}{2(x-2) }$

Step-by-step explanation:

The given expression to us is ,

$\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}$

Now take the LCM as ( x - 1 ) and Simplify , we have ,

$\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}$

Simplifying further , we get ,

$\implies \dfrac{ -4x+7}{2(x-2) }$

Hence the second option is correct .

A ball with mass m kg is thrown upward with initial velocity 28 m/s from the roof of a building 17 m high. Neglect air resistanc

Nutka1998 [239]

a. At its maximum height, the ball has zero vertical velocity, so

$-\left(28\dfrac{\rm m}{\rm s}\right)^2=2(-g)(y_{\rm max}-17\,\mathrm m)$

$\implies y_{\rm max}=57\,\mathrm m$

b. The ball's height in the air $y$ at time $t$ is given according to

$y=17\,\mathrm m+\left(28\dfrac{\rm m}{\rm s}\right)t-\dfrac g2t^2$

Solve for $t$ when $y=0$ :

$17+28t-4.9t^2=0\implies t\approx6.3\,\mathrm s$

A recent survey found that 30% of telephone users have switched completely to cell phone use (i.e. they do not have landlines in

Genrish500 [490]

Answer:

The probability that exactly 30% of these 10 telephone users do not have landlines in their homes is 0.2668.

Step-by-step explanation:

We are given that a recent survey found that 30% of telephone users have switched completely to cell phone use (i.e. they do not have landlines in their homes).

A random sample of 10 of these customers is selected.

The above situation can be represented through binomial distribution;

$P(X = r) = \binom{n}{r}\times p^{r} \times (1-p)^{n-r}; x = 0,1,2,3,......$

where, n = number of trials (samples) taken = 10 customers

r = number of success = 30% of 10 = 3

p = probability of success which in our question is the probability

that telephone users do not have landlines in their homes,

i.e. p = 30%

Let X = Number of telephone users who do not have landlines in their homes

So, X ~ Binom(n = 10, p = 0.30)

Now, the probability that exactly 30% of these 10 telephone users do not have landlines in their homes is given by = P(X = 3)

P(X = 3) = $\binom{10}{3}\times 0.30^{3} \times (1-0.30)^{10-3}$

= $120 \times 0.30^{3} \times 0.70^{7}$

= 0.2668
