PLS HELP

Mathematics
1 answer:
Radda [10]3 years ago
8 0

Answer:

-m + 2n - 2

Step-by-step explanation:

R - [S + T]

Since we know  R = 11 - 2m, S = n + 5, and T = -m - 3n + 8,

we can substitute them in.

Replacing R,S and T

11 - 2m - [n + 5+-m - 3n + 8]

Combine inside the brackets

11 - 2m - [n  - 3n-m +5+ 8]

11-2m -[ -2n -m +13]

Distribute the minus sign

11-2m - -2n --m -13

11-2m +2n +m -13

Combine like terms

m-2m +2n +11 -13

-m +2n -2

Find the definite integral from 0 to 1/16 of arcsin(8x)/sqrt(1-64x^2)dx
kolezko [41]
\displaystyle\int_0^{1/16}\frac{\arcsin8x}{\sqrt{1-64x^2}}\,\mathrm dx

First let y=8x, so that \mathrm dx=\dfrac{\mathrm dy}8 to write the integral as

\displaystyle\frac18\int_0^{1/2}\frac{\arcsin y}{\sqrt{1-y^2}}\,\mathrm dy

Now recall that (\arcsin y)'=\dfrac1{\sqrt{1-y^2}}, so substituting z=\arcsin y should do the trick. The integral then becomes

\displaystyle\frac18\int_0^{\pi/6}z\,\mathrm dz=\frac1{16}z^2\bigg|_{z=0}^{z=\pi/6}=\frac{\pi^2}{576}

Please help lol... find the m
erastova [34]

Answer:

Angle A  =35

Step-by-step explanation:

ok that is a triangle

look exterior plus interior is 180

corresponding angles

x+74

now lets solve for the angle a

triangle = 180 degrees

180=73+x+74+37+x

combine like terms

x=−2

now plug in for angle a

37+(-2)

=35

Which step in the construction of copying a line segment ensures that the new line segment has the same length as the original l
anzhelika [568]

Answer:

Now out of these points, i guess steps 5 and 6 are the main steps that ensure that the copied line segment is exactly the same as the original segment.

Step-by-step explanation:

Here are the steps I think you probably will go through.

1. Draw a line that is longer than the segment but shorter than the width of the page.

1a. Make sure this line is  at least 1/2 inch from the left hand side.  

2. Use a compass to measure the length of the original segment. Never use a ruler. Rulers do not exist in pure geometry.

3. Measure out the distance on the line you just drew with the compass. One end is on the left hand edge and the other end (the pencil end) is marking the segment so it is the same length as the compass. You are done.

The key step either two or three.The steps to copy a line segment are given below:

1. Lets start with a line segment AB that we have to copy.

2. Now mark a point C. below or above AB, that will be one endpoint of the new line segment.

3. Now, put the compass tip on point A of the line segment AB.

4. Spread the compass up to point B, so as the compass width is equal to length of AB.

5. Without changing the compass width, now place the compass tip on the point C that you made in step 2.

6. Now, draw an arc roughly without changing the compass settings. Mark that point D. This will form the new line segment.

7. Draw a line from C to D.

Now out of these points, i guess steps 5 and 6 are the main steps that ensure that the copied line segment is exactly the same as the original segment.
