<h2>QUESTION:- What is the value of y?</h2>

<h2>ANSWER:- </h2>

SUM OF ALL INTERIOR ANGLE = 180

y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 72 \\ 2y = 108 \\ y =  \frac{108}{2}  \\ y =  \frac{ \cancel{108}^{ \:  \:  \:  \tiny{54}}  }{ \cancel{2}}  \\ y = 54 \degree

the sum of triangle is 180 :

y + y + 72 = 180 \\ 2y + 72 = 180 \\ 2y = 180 - 75 \\ 2y = 108 \\ y =  \frac{108}{2}  \\ y = 54

Stephanie is 62 inches tall. Her brother is t inches shorter than she is.
Law Incorporation [45]

Answer: 62 - T

Step-by-step explanation:

I think it is 62 - T because Stephanie is 62 inches and it says that her brother is shorter which I believe it means that you have to subtract.

What 5 numbers that has a median equal to 7?
Elza [17]
Median is where if you put them in ascending order and cross them off, one from each side at a time, you get to the middle number.
56789 is your answer but so would any group of 5 numbers where two are bigger and two smaller than seven.

Can someone tell me if i did this right? im also not sure which one is the scale factor.
PIT_PIT [208]
If you are moving the center of circle 2 to the the center of circle 1, then the translation rule is (x,y) ---> (x+4, y+10). 
Note how x = 1 turns into x = 5. So we add 4
Also, y = -2 turns into y = 8. We add 10

The scale factor to turn the radius r = 4 into r = 8 is 2. Basically we double the radius. We can divide the two radii to see 8/4 = 2

----------------------------------

Summary:
To go from circle 2 to circle 1, we apply these two transformations
translation: (x,y) ---> (x+4, y+10)
dilation: scale factor 2

note: 
if you want to go backwards, go from circle 1 to circle 2, then undo the transformations above

Which expression is equivalent to Left-bracket log 9 + one-half log x + log (x cubed + 4) Right-bracket minus log 6? log StartFr
dybincka [34]

Answer:

  \log{\dfrac{3\sqrt{x}(x^3+4)}{2}}

Step-by-step explanation:

\log{9}+\dfrac{1}{2}\log{x}+\log{(x^3+4)}-\log{6}=\log{\left(\dfrac{9x^{\frac{1}{2}}(x^3+4)}{6}\right)}\\\\=\boxed{\log{\dfrac{3\sqrt{x}(x^3+4)}{2}}}\qquad\text{matches choice A}

__

The applicable rules of logarithms are ...

  log(ab) = log(a) +log(b)

  log(a/b) = log(a) -log(b)

  log(a^b) = b·log(a)
