Solve for x (7/2x)+(6/4X)=(5X/4)
Bess [88]

Answer:

x=0

Step-by-step explanation:

7/2x+6/4x=5/4x

7/2x=5/4x-6/4x

7/2x=-1/4x

7/2x-(-1/4x)=0

7/2x+1/4x=0

14/4x+1/4x=0

15/4x=0

x=0/(15/4)

x=0

In a solar system, two comets pass near the sun, which is located at the origin. Comet E is modeled by quantity y plus 16 end qu
Leya [2.2K]

Explanation:

The equation of comet E is given below as

\frac{(y+16)^2}{400}+\frac{x^2}{144}=1

The equation of comet H is modelled below as

\frac{(y+13)^2}{144}-\frac{x^2}{25}=1

Given, that the Sun is located at the origin.

This is an equation of an ellipse. So, the path traveled by Comet e is an elliptic path.

Comparing with the Standard equation of ellipse: below,we will have

\frac{(y-k)^2}{b^2}+\frac{(x-h)^2}{a^2}

Whise center is

\begin{gathered} center=(h,k) \\ vertices=(h\pm a,0) \end{gathered}

By comparing coefficient, we will have

\begin{gathered} a^2=144 \\ a=12 \\ b^2=400 \\ b=20 \\ k=-16 \\ h=0 \\ (h,k)=(0,-16) \end{gathered}

Hence,

The vertex of comet E will be

\begin{gathered} (h\pm a,0) \\ (0+12,0),(0-12,0) \\ (12,0),(-12,0) \end{gathered}

The vertex of comet E is

(12,0),(-12,0)

Part C:

It is the foci forboth comets

\begin{gathered} cometE: \\ c=\sqrt{b^2-a^2} \\ c=\sqrt{400-144} \\ c=\sqrt{256} \\ c=16 \\  \\ For\text{ comet F:} \\ c=\sqrt{a^2-b^2} \\ c=\sqrt{144+25} \\ c=\sqrt{169} \\ c=13 \end{gathered}

Hence,

The foci will be

\begin{gathered} (16\pm16,0) \\ cometE \\ (0,0),(32,0) \\ cometF: \\ (13\pm13,0) \\ (0,0),(26,0) \end{gathered}

What is the area of a circle with a diameter of 37 inches?
krek1111 [17]
Hello!

To find the area of a circle you use the equation

\pi  r^{2}

r is the radius which is half the diameter

\pi  18.5^{2}

Square 18.5

\pi *342.25

Put this into the calculator and you get the answer of about 1075.21

The answer is about 1075.21

GET 95 POINTS Let f(x) = 1/x and g(x)=x² + 6x. What
Dimas [21]

Answer:

hey there hope this answer helps you out

Step-by-step explanation:

we have two functions f(x) and g(x) such that

f(x) =  \frac{1}{x}

and

g(x) =  {x}^{2}  + 6x

solving for f ° g, we'll substitute the x in f(x) by the value of g(x)

fog =  \frac{1}{g(x)}

fog \:  = \frac{1}{ {x}^{2} + 6x }

taking x common in denominator

fog =   \frac{1}{x(x + 6)}

for a function to exist it should not have 0 in its denominator

checking the values of x for which the denominator of f ° g becomes 0 :-

  • x = 0 and
  • x = -6

so the function doesn't exist at values x = 0, -6

<h3>So, <u>0, -6</u> cannot be in the domain of f°g</h3>
