Solve for x................

alexandr402 [8]

Answer:

Option C

$x={1(+/-)2\sqrt{3}}$

Step-by-step explanation:

we have

$x^{2}-2x-11=0$

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-2x-11=0$

$a=1\\b=-2\\c=-11$

substitute

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-11)}} {2(1)}$

$x=\frac{2(+/-)\sqrt{4+44}} {2}$

$x=\frac{2(+/-)\sqrt{48}} {2}$

$x=\frac{2(+/-)4\sqrt{3}} {2}$

$x={1(+/-)2\sqrt{3}}$

The graph of f(x) =sqrt of x is reflected across the x-axis and then across the y-axis to create the graph of function g(x). Whi

pickupchik [31]

The original function is

f(x)=√x

As this is condition for √x function, x≥ 0

So,

Domain= [0, infinity)

Range= [0, infinity)

After the reflection across x-axis and y-axis, we get a function,

g(x)=-√-x

-x≥ 0 means x≤ 0,

So,

Domain= (-infinity, 0]

Range= (-infinity, 0]

From this you can see that

-The only value that is in the domains of both functions is 0.

-The range of g(x) is all values less than or equal to 0.

only these points are correct and all other points are wrong.

See the attached graphs for both functions.

The value of a rectangle is 128 cubic yards. The base of the prism has an area of 8 square yards.

san4es73 [151]

Answer:

<h2>16 yards</h2>

Step-by-step explanation:

Given,

Volume of the rectangular prism = 128 cubic yards

Base area of the prism = 8 square yards

Let,

Height of the prism be = h

As we know, 

Base area × height = Volume of the given prism

Therefore, 

By the problem,

=> 8 sq. yd × h = 128 cu. yd

=> 8h = 128

(On dividing 8 from both sides)

$= > \frac{8h}{8} = \frac{128}{8}$

(On Simplification)

=> h = 16

Hence, the height (h) of the prism is 16 yards (Ans)
