How does 2π/4 simplify to π/4?

Mathematics
1 answer:
lana [24]3 years ago

It doesn't
remember that
(x/g) times (y/z)=(x time y)/(g times z) so
2pi/4=(2 times pi)/(4 times 1) so
2pi/4=2/4 times pi/1=1/2 times pi/1=pi/2

Triangle MNP is graphed on a coordinate grid with vertices at M (−3, −6), N (0, 3) and P (6, −3). Triangle MNP is dilated by a s
bulgar [2K]
<h3>Answer: Choice D) (6u, -3u)</h3>

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

Explanation:

The letter u represents the scale factor. It is some unknown number.

To form the dilation, we multiply this number u by each coordinate of point P (6, -3)

The x coordinate of P is x = 6. It turns into x*u = 6*u which is the x coordinate of P '

Similarly, y = -3 for point P so y*u = -3*u is the y coordinate of point P '

Therefore, we go from P(6, -3) to P ' (6u, -3u)

What is the general form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)?
AnnZ [28]

Answer:

x^{2}+y^{2} +4x-2y+1=0

Step-by-step explanation:

we know that

The general form of the equation of a circle is

x^{2} +y^{2}+ Dx + Ey + F=0

where D, E, F are constants

step 1

Find the radius of the circle

Remember that the distance from the center to any point on the circle is equal to the radius

so

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

(-2,1)\\(-4,1)  

substitute the values

r=\sqrt{(1-1)^{2}+(-4+2)^{2}}

r=\sqrt{(0)^{2}+(-2)^{2}}

r=2\ units

step 2

Find the equation of the circle in standard form

(x-h)^{2} +(y-k)^{2}=r^{2}

In this problem we have

center ( -2,1)

radius r=2 units

substitute

(x+2)^{2} +(y-1)^{2}=2^{2}

(x+2)^{2} +(y-1)^{2}=4

Step 3

Convert to general form

(x+2)^{2} +(y-1)^{2}=4\\ \\x^{2}+4x+4+y^{2}-2y+1=4\\ \\x^{2}+y^{2} +4x-2y+1=0

What would the answer be?​
NikAS [45]

Answer:

11.35%  

Step-by-step explanation:

Add all of the numbers together to get the total amount of people who visited.

Add all the numbers in the teen section to find how many teens visited.

If you put teens over whole it will give you the fraction 86/758

If you divide 86 by 758 you will get 0.11345646438 .

Move the decimal two places to the right and round to get the percent 11.35.
