Write the standard form of the equation of the specified circle. Endpoints of a diameter: (−x, −y), (x, y)

Mathematics

BARSIC [14]3 years ago
7 0

SOLUTION IS

WE KNOW STANDARD EQUATION OF CIRCLE[tex](X-a)^{2}+(Y-b)^{2}=r^{2}

where (a,b) is centre and r is radius of circle

now we have to find component of centre and radius

we know centre of circle is equidistance from end points of diameter

apply formula to find mid point of line( (x1+x2)/2,(y1+y2)/2) we get

((x-x)/2,(y-y)/2)=(0,0)

hence component of circle is (0,0)

now apply distance formula between (0,0)and (x,y)

we get x^{2}+y^{2}=r^{2}

hence standard equation of circlre is =X^{2}+Y^{2}=x^{2}+y^{2}

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.
ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

Exp\ 1:3m-4n\\Exp\ 2: n^2-m

The values are:

m=5\\n=-2

Putting the values in expression 1:

3m-4n\\=3(5)-4(-2)\\=15+8\\=23

Putting the values of m and n in second expression

n^2-m\\=(-2)^2-5\\=4-5\\=-1

Multiplying both expressions:

(3m-4n)(n^2-m)=23* (-1)=-23

Hence the correct answer is C) -23

1 )  9 x + 18 > 9 x - 27
9 x - 9 x > - 27 - 18
0 * x > - 45
Always true
2 ) 6 x - 13 < 9 x - 12
6 x - 6 x < - 12 + 13
0 * x < 1
Always true
3 ) - 6 ( 2 x - 10 ) + 12 x ≤ 180
- 12 x + 60 + 12 x ≤ 180
0 * x ≤ 180 - 60
0 * x ≤ 120
