Answer:

use the equation y2-y1/x1-x2 or the equation mx+b so 4x is the slope and 8 is the intercept...can u give me brainliest please and ill asure u of my fast response always

Write out the first few terms of the series Summation from n equals 0 to infinity (StartFraction 2 Over 3 Superscript n EndFract

anyanavicka [17]

Answer:

$\sum\limits_{n=0}^{\infty} \frac{2}{3^n}\frac{(-1)^n}{5^n} = 15/8$

Step-by-step explanation:

The sum you are trying to understand is this.

$\sum\limits_{n=0}^{\infty} \frac{2}{3^n}\frac{(-1)^n}{5^n}$

Remember that in general when you have a geometric series

$\sum\limits_{n = 0}^{\infty} a*r^n$ you have that

$\sum\limits_{n = 0}^{\infty} a*r^n = \frac{a}{1-r}$ and that equality is true as long as $|r| < 1$ .

Therefore here we have

$\sum\limits_{n=0}^{\infty} \frac{2}{3^n}\frac{(-1)^n}{5^n} = \sum\limits_{n=0}^{\infty} 2* \big(\frac{-1}{3*5} \big)^n = \sum\limits_{n=0}^{\infty} 2* \big(\frac{-1}{15} \big)^n$ and $\big|\frac{-1}{15} \big| = \frac{1}{15} < 1$

Therefore we can use the formula and

$\sum\limits_{n=0}^{\infty} 2* \big(\frac{-1}{15} \big)^n = \frac{2}{1-(-1/15)} = \frac{2}{1+1/15} = 30/16 = 15/8$

What is the y-intercept of the line perpendicular to the line...

Dominik [7]

Answer:

D) 5

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes.

The line: $y=\frac{3}{4} x+3$ has a slope of $\frac{3}{4}$ as it is in y=mx+b form, where m is the slope, and b is the y-intercept.

Since the slope is $\frac{3}{4}$ , we see that the negative reciprocal slope is $-\frac{4}{3}$ , as $\frac{4}{3}$ is the reciprocal (flip the numerator and denominator).

From here, we can use point slope form: $y - y1 = m(x- x1)$ , where $(y1, x1)$ is the point. In this case, (3, 1) is the point.

Thus, we have: $y-1 =-\frac{4}{3}(x-3)$ as our final equation.

Simplifying: $y-1 = -\frac{4}{3}x+4$

And: $y=-\frac{4}{3}x+5$ , which gives us the y-intercept to be 5.

Let me know if this helps!

In a multiple regression analysis what would likely be the culprit of a dramatic increase in the P-value of one of the variables

makvit [3.9K]

This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity.
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>
