stira [4]

Answer:

(a) Domain: x > 4

(b) Range: y < -2

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted by function f(x).

We see that our x-values span from 4 to infinity. Since it is an open dot, we cannot include it in our domain:

(-4, ∞)

We also see that our y-values span from -2 to negative infinity. Since it is an open dot, we cannot include it in our range:

(-∞, -2)

Ho do you get the Surface Area of this shape?
blsea [12.9K]
This solid object contains 8 sides.

The side that is facing you has a surface area:

64f{ t }^{ 2 }+84f{ t }^{ 2 }=148f{ t }^{ 2 }

The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.

The bottom side has a surface area:

84f{ t }^{ 2 }

The side to your right has a surface area:

84f{ t }^{ 2 }

The side to your left has a surface area:

48f{ t }^{ 2 }

The side to your top left has a surface area:

48f{ t }^{ 2 }

The side beside the side to the top left has a surface area:

36f{ t }^{ 2 }

The side at the very top has a surface area:

36f{ t }^{ 2 }

Combined, the surface area is:

S=2\cdot 148f{ t }^{ 2 }+2\cdot 84f{ t }^{ 2 }+2\cdot 48f{ t }^{ 2 }+2\cdot 36f{ t }^{ 2 }

\\ \\ =296f{ t }^{ 2 }+168f{ t }^{ 2 }+96f{ t }^{ 2 }+72f{ t }^{ 2 }\\ \\ =632f{ t }^{ 2 }

Therefore the answer is: C

Convert 11.42424242 to a rational expression in the form a/b, where b=0
lutik1710 [3]
I think you mean b is not equal to 0.

We have that 11.424242... = 11 + 0.424242...
Now let x = 0.424242...
Then 100x = 42.424242...
Now 99x = 100x - x = 42 so 99x = 42 and therefore x = 42/99

Now we can simplify 42/99 to 14/33

Now combining this we get 11.424242... = 11 + 14/33
= 363/33 + 14/33 = 377/33

8x - 4y = -12 solve for y
son4ous [18]
Solving an equation means finding a value of a variable that make the equation true. This value is called the solution of the equation. A mathematical equation is just like a balanced equation. Both sides of the equation should be equal at all times. Whatever we do to one side, has to be done on the opposite side. 

8x - 4y = -12 

4(2x-y)=-12&#10;&#10; &#10;   Factor \ out \ the \ common \ term \ 4

2x-y=- \dfrac{12}{4}    Divide \ both \ sides \ by \ 4

2x-y=-3&#10;&#10; &#10;&#10; 

-y=-3-2x       Subtract \ 2x \ from \ both \ sides

y=3+2x        Multiply \ both \ sides \ by \ -1

A plane is descending towards a runway in Chicago. The plane is flying at an altitude of 11 miles and is 193 miles from the runw
Flura [38]

The plane will make an angle 3.26^{\circ} with the runway.

Explanation:

Given that the plane is flying at an altitude of 11 miles and is 193 miles from the runway, as measured from the ground.

We need to determine the angle that the plane will make with the runway.

From the given measurements, we can see that it is a right angled triangle. Hence, let us use the tangent formula to determine the angle.

The formula for the tangent is given by

tan \ \theta=\frac{opp}{adj}

Where opp=11 and adj=193

Substituting these values in the above equation, we get,

tan \ \theta=\frac{11}{193}

Dividing, we get,

tan \ \theta=0.057

Taking tan^{-1} on both sides of the equation, we get,

\theta= tan^{-1}(0.057)

Simplifying, we have,

\theta= 3.26^{\circ}

Hence, the angle that the plane will make with the runway is 3.26^{\circ}
