Help ASAP BRAIN IF RIGHT The width of a rectangle is 12 units. Can the perimeter P of the rectangle be 60 units when its length

x is 18 units?
No, because P ≠ 2x + 2(12)
No, because P = 2x + 2(12)
Yes, because P ≠ 2x + 2(12)
Yes, because P = 2x + 2(12)

Answer:

Yes, because P = 2x +2(12)

Step-by-step explanation:

As the formula for perimeter is 2(L+B).

Let L=x=18

B=12

Then, perimeter, P=2(18+12) = 2(30) = 60

Hence, we get the perimeter as 60 units.

Find the vertices and foci of the hyperbola with equation quantity x plus one squared divided by sixteen minus the quantity of y
katrin2010 [14]

Answer:

The vertices are (3 , -5) , (-5 , -5)

The foci are (4 , -5) , (-6 , -5)

Step-by-step explanation:

* Lets study the equation of the hyperbola

- The standard form of the equation of a hyperbola with  

  center (h , k) and transverse axis parallel to the x-axis is

  (x - h)²/a² - (y - k)²/b² = 1

- The length of the transverse axis is 2 a

- The coordinates of the vertices are  (h  ±  a  ,  k)

- The coordinates of the foci are (h ± c , k), where c² = a² + b²

- The distance between the foci is  2c

* Now lets solve the problem

- The equation of the hyperbola is (x + 1)²/16 - (y + 5)²/9 = 1

* From the equation

# a² = 16 ⇒ a = ± 4

# b² = 9 ⇒ b = ± 3

# h = -1

# k = -5

∵ The vertices are (h + a , k) , (h - a , k)

∴ The vertices are (-1 + 4 , -5) , (-1 - 4 , -5)

* The vertices are (3 , -5) , (-5 , -5)

∵ c² = a² + b²

∴ c² = 16 + 9 = 25

∴ c = ± 5

∵ The foci are (h ± c , k)

∴ The foci are (-1 + 5 , -5) , (-1 - 5 , -5)

* The foci are (4 , -5) , (-6 , -5)

Could someone PLEASE just HELP me with this question.

<u>Answer</u>

\frac{7}{37}


<u>Detailed Explanation </u>

To simply answer this, since .189 has three digits we are going to be inserting 999 as the denominator since it is a repeating decimal.


\frac{189}{999}


We could simplify the answer!

\frac{189}{999}


Therefore, the answer would simply be \frac{7}{37}

\frac{7}{37}


<u>Always Remember </u>

In the future, always remember whenever you have a three digit decimal and the problem asks you to convert it into a fraction, you should always insert 1000 as the denominator (the numerator is basically the decimal without the decimal point) and simplify if necessary.

The graph of g(x) is the graph of f(x)=x+6 reflected across the x-axis.Which equation describes g?
Mandarinka [93]
Reflected across x axis means y turns to -y, meaning, multiply the whole function by -1

f(x) times -1=-1 times (x+6)=-x-6
