Can anyone help me pls ( if you can, can you do it on paper and post it with the answer)

A student is constructing a pair of perpendicular lines using a compass and ruler. Here are her first steps:

Katyanochek1 [597]

The next step she should take is to use her ruler to join the given point to the point where the arcs intersect.

<h3>Steps in constructing perpendicular lines</h3>

Place your compass on the given point
Draw an arc across the line on each side of the given point. Do not adjust the compass width when drawing the second arc
From each arc on the line, draw another arc on the opposite side of the line from the given point. The two new arcs will intersect.
Use your ruler to join the given point to the point where the arcs intersect.
Use your compass and ruler to draw a perpendicular line from each given point to the line segment

From this, we can deduce that her next step is to use her ruler to join the given point to the point where the arcs intersect

Thus, the next step she should take is to use her ruler to join the given point to the point where the arcs intersect.

Given the third-order differential equation z′′′+2z′′−4z′−8z=0, find the general solution. Enter your solution as z(x)=... . In

Scorpion4ik [409]

Answer: $z(x) = c_{1} e^{2x} +c_{2} e^{-2x} + c_{3} xe^{-2x}$

Step-by-step explanation:

This is a <em>homogeneous linear third-order differential equation</em>

z′′′+2z′′−4z′−8z=0 so the

FIRST STEP is to find the characteristic equation and its roots

Using the method of finding roots of a polynomial (using m = 2) would provide the solution below

(m-2)(m+2)(m+2)=0; m = 2 and m = -2 (repeated twice)

SECOND STEP is to write the general solution with the arbitrary constants.

The general solution based on the roots and the using x as the independent variable would provide

$z(x) = c_{1} e^{2x} +c_{2} e^{-2x} + c_{3} xe^{-2x}$

<em>*It should be noted that when the characteristic equation has a repeated root, the general equation form becomes similar to the last part of the answer*</em>

A total of 8 representatives need to be chosen from a group of 40 students, of which 24 are female and 16 are male. In how many

Diano4ka-milaya [45]

Answer:

Probability = 0.0147

Step-by-step explanation:

To find this, we need to know the number of ways the representatives can be picked overall, and then the number of ways 3 females and 3 males can be the representatives. The fraction of the two will be the probability.

The total number of ways the representatives can be picked is the combination of a pool of 40 students and choosing 8 is; C(40,8) = 40!/((8!)(40 - 12)!)

= 76904685

We have gotten the number of ways the representatives can be picked.

Now let's find how many ways can the jury consist of 3 females and 3 males

For the males, there are 16 in the pool and we're picking 3:

Thus, C(16,3) = 16!/((3!)(16 - 3)!) = 560

For the females, there are 24 in the pool and we're picking 3:

Thus, C(24,3) = 24!/((3!)(24 - 3)!) = 2024

Thus, number of men and women choices = 2024 x 560 = 1133440

So; probability = 1133440/76904685 = 0.0147
