Is the square root of 7 minus the square root of 7 a rational number?

Answers

Answer 1

Answer:

No

Step-by-step explanation:

Forgive me if i'm wrong lol

so the square root of 7 is 2.64, 2.64 minus 2.64 is 0, and it is not rational since it can't be written as a fraction.

dont hate me if im wrong im so sorry <3

A lion passes through the point (-8,-2) and has a slope of - 3/4. write an equation in slope intercept form for this line.

Answers

The equation would be y=-3/4x+8
Explanation
Since the line passes through the point (-8,-2) and the slope is -3/4 go down 3 points and to the right 4 points from the point (-8,-2) which would equal m. Your line should then pass through -8 on the y-axis which equals b.

Slope-intercept form
Y=mx+b
m= slope
b= y-intercept

Find the sum. Write your answer in the simplest form
2/7 + 2/5

Answers

Answer:

#1. 3/8 and #2. 27/35

Step-by-step explanation:

3/4 - 3/8 change to 6/8 - 3/8 = 3/8 can not reduce

2/7 + 2/5 change to 10/35 + 17/35 = 27/35 can not reduce

Answer:

3/8

Step-by-step explanation:

3/4 - 3/8

= 3*2/4*2 - 3/8

= 6/8 - 3/8

= 6-3/8

= 3/8

Answer:

24/35

Step-by-step explanation:

2/7 + 2/5

= 2*5/7*5 + 2*7/5*7

= 10/35 + 14/35

= 10+14/35

=24/35

An electronics company finds that 5 out of 75 capacitors produced are damaged. How
many damaged items can they expect if the company produces 1,500 capacitors?

Answers

Answer:  100

=============================================

Explanation:

5/75 = 1/15 means that 1 out of every 15 capacitors are damaged.

Multiplying this with the 1500 capacitors produced, we expect about (1/15)*1500 = 1500/15 = 100 capacitors are damaged in this batch.

---------

A slightly different approach:

Saying "1 out of every 15 capacitors are damaged" means we can form the ratio

1 damaged: 15 total

Then multiply both sides by 100 so that the "15 total" jumps up to "1500 total" and we get the following

1 damaged: 15 total

100*(1 damaged): 100*(15 total)

100 damaged: 1500 total

We get the same answer as before.

Keep in mind that it's not a guarantee that we'll find 100 damaged capacitors out of 1500 total, but rather this is an estimate based on the average. So instead of saying "there are 100 damaged capacitors" it would be better to say "there are expected to be about 100 damaged capacitors".

100 items can they expect if the company produces 1,500 capacitors.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

An electronics company finds that 5 out of 75 capacitors produced are damaged.

So, if there are 1500 capacitors then the damaged one are

= 5/ 75 x 1500

= 5 x 20

= 100 capacitors

Someone explain to me how to write an equation out in slope-intercept form in simple terms with examples I'm so confused

Answers

Answer:

are you talking about y=mx+b? M would be the slope, and B would be the y intercept, so if we wanted to do, lets say 4,5, we would say y=4x+5, i think,

Step-by-step explanation:

An equation in slope-intercept form looks like this: y = mx+b

In the equation, m is equal to the growth rate of the line on the graph and b represents the y-intercept (where the line meets with the y-axis).

For the line shown in the picture below, the equation is y = 1x + 2 (not exactly but based on estimates). Also, you can ignore the writing on the picture. (0-0')

y = 1x + 2

In this equation. 1 represents the growth rate and 2 represents the y-intercept.

So, when writing an equation, look for these two things:

y-intercept: where the line of a graph meets with the y-axis

growth rate: how much is the line increasing by on the y-axis for every unit on the x-axis?

The line L is a tangent to the circle x2 + y2 = 45 at the point (-3, 6).
The line L crosses the x-axis at the point P.
Work out the coordinates of P.

Answers

Answer:

The point P is (-15,0).

Step-by-step explanation:

We need to find the slope of the line L to get the coordinates of P.

We know that L is tangent to the circle at point (-3, 6), which means L is perpendicular to the radius of the circle (a line between the origin (0,0) and the tangent point (-3,6))

So let's find the slope or the radius.

[tex]m_{R}=\frac{6-0}{-3-0}[/tex]    

[tex]m_{R}=-2[/tex]

Now, we know that if two lines are perpendiculars their slopes follow the rule:

[tex]m_{L}=-\frac{1}{m_{R}}[/tex]  

[tex]m_{L}=\frac{1}{2}[/tex]  

Knowing the slope of L we can find the equation of this line. The slope-intercept equation of a line is:

[tex]y=mx+b[/tex]

[tex]y=\frac{1}{2}x+b[/tex]

Using the point (-3,6) we can find b.

[tex]6=\frac{1}{2}(-3)+b[/tex]

[tex]b=\frac{15}{2}[/tex]

The line equation will be:

[tex]y=\frac{1}{2}x+\frac{15}{2}[/tex]

The point P has only an x-coordinate value (x,0)

So we have:

[tex]0=\frac{1}{2}x+\frac{15}{2}[/tex]

[tex]x=-15[/tex]

Therefore, the point P is (-15,0).

- line CD is perpendicular to segment AB
- point M is the midpoint of segment AB

9514 1404 393

Answer:

  a, b, e (only)

Step-by-step explanation:

The circle centered at A is all of the points that are distance AB from A.

The circle centered at B is all of the points that are distance AB from B.

The points C and D are points that are distance AB from both A and B.

The line joining those points (C and D) consists entirely of points that are equal distances from A and from B. CD is the perpendicular bisector of AB.

Point M is one of the points on line CD, and is also on segment AB. Because it is on CD, we know it is the same distance from A as from B. That means AM = BM, and M is the midpoint of AB.

__

Points B, C, D are not on the same line, so can form a triangle. As with any triangle, the sum of any two segments is greater than the length of the third. Here, this is expressed as CB + BD > CD.

__

With some work using the Pythagorean theorem, you can show that ...

  CM = AM×√3

Similarly, MD = BM×√3.

Adding these two relations tells us ...

  CM +MD = √3(AM +BM)

  CD = AB×√3 . . . . . AB and CD are not the same length

__

AM and BM are on the same line, so cannot be perpendicular to each other.
