The midpoint of AB is M ( 1 , − 3 ). If the coordinates of A A are ( − 6 , − 7 ),what are the coordinates of B?
Leno4ka [110]

Answer:

a= -4

b=1

Step-by-step explanation:

Midpoint=(1,-3)=(x,y)

A=(-6,-7)=(x1,y1)

Let ,the coordinates of B be 'a and b' .

So,

B=(a,b)=(x2,y2)

Using ,midpoint formula,

(x,y)=(x1+x2\2 , y1+y2 \2)

or, (1,-3)=(-6+a\2 , -7+b \2)

Now,

Taking the corresponding sides,

or, 1 =-6+a/2

or, 1*2=6+a

or, 2=6+a

or, 2-6=a

a=-4

Then,

-3= -7+b/2

or, -3*2= -7+b

or, -6 =-7+b

or, -6+7=b

b=1

The graph of the quadratic parent function was transformed to create the graph g(x) = f(x) - 9. Which statement about the graphs
MakcuM [25]

9514 1404 393

Answer:

  D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

Step-by-step explanation:

Subtracting 9 from the function value moves every point on the graph down 9 units. That includes the y-intercept.

  D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

The radius of the hydrogen atom is 0.529x10/-10 and the radius of the nucleus is 1.2x10/-15m. Compare the radius of each by writ
raketka [301]

we know that

The radius of the hydrogen atom is  0.529*10^{-10}m

The radius of the nucleus is  1.2*10^{-15}m

the ratio is equal to

\frac{0.529*10^{-10}}{ 1.2*10^{-15}} = 44,083.33

that means the radius of the hydrogen atom is 44,083.33 times the radius of the nucleus

therefore

<u>the answer is</u>

the ratio is equal to 44,083.33
