Answer:

Step-by-step explanation:

ok, so this is an infinitly repeating function, so you can write it as:

sqrt(12-x)

Although, x is also equal to sqrt(12-x), so

x = sqrt(12-x), and

x^2 = 12-x

x^2-12+x = 0

now just apply the quadratic formula and you're good

hope i helped :D

Reil [10]

Answer:

Equation:

$15=\dfrac{1}{2}x+8$

Student ticket price = $14

Step-by-step explanation:

An adult ticket = $15

Let a student ticket = $x

An adult ticket is half the price of a student ticket plus $8, then an adult ticket

$=\$\left(\dfrac{1}{2}x+8\right)$

Equate the prices for the adult ticket:

$15=\dfrac{1}{2}x+8$

Subtract 8 from both sides:

$15-8=\dfrac{1}{2}x+8-8\\ \\7=\dfrac{1}{2}x$

Multiply this equation by 2:

$7\cdot 2=x\\ \\x=\$14$

If cos A = 3 over 11, then which of the following is correct?

ziro4ka [17]

Answer: The answer is (a) sec A = 11 over 3.

Step-by-step explanation: Given that Cosine of an angle 'A' is 3 over 11,

i.e.,

$\cos A=\dfrac{3}{11}.$

And we need to find which one of the given four options is correct.

We have the following relations between cosine, secant and cosecant of an angle from trigonometry.

$\sec A=\dfrac{1}{\cos A}~~\textup{and}~~\csc A=\dfrac{1}{\sqrt{1-\cos^2 A}}.$

Therefore,

$\sec A=\dfrac{11}{3}$

and

$\csc A=\dfrac{1}{\sqrt{1-\frac{9}{121}}}=\dfrac{1}{\sqrt{\frac{112}{121}}}=\dfrac{11}{4\sqrt 7}.$

Thus, the correct option is (a) sec A = 11 over 3.
