Answer:

Asymptotes are the points where the function tends to a given value, and the discontinuities are the points where the denominator is zero.

The function is:

f(x) = \frac{x + 1}{(x^2 + 3x + 2)}

The discontinuitys are when x^2 + 3x + 2 = 0

So we need to find the roots of that quadratic equation, and those are:

x = \frac{-3 +-\sqrt{3^2 - 4*3*1} }{2*1} = \frac{-3+-\sqrt{-3} }{2}

The number inside the square root, the determinant, is smaller than zero, this means that the roots are imaginary, so there is no real number x such that the denominator is equal to zero, so we do not have any discontinuity in this equation.

Now, we may have asymptotes as x goes to infinity and -infinity.

Because grade of the polynomial in the denominator is bigger than the one in the numerator, as x goes to infinity, the function will go asymptotically to +0, and as x goes to minus infinity, the function will trend asymptotically to -0

James notes the angle of elevation of the top of tower to be 30 degree if James is 100meter away horizontally from the base of t
noname [10]

Answer:

h = 57.73 m

Step-by-step explanation:

We have,

The angle of elevation of the top of tower to be 30 degree

James is 100 m away horizontally from the base of the tower.

It is required to find the height of the tower.

Here, angle is 30 degree

Base, b = 100 m

Let h is the height of the tower. The relation between base and height is given by :

\tan\theta=\dfrac{h}{b}\\\\h=b\times \tan\theta\\\\h=100\times \tan(30)\\\\h=57.73\ m

So, the height of the tower is 57.73 m.

(NEED HELP ASAP!!) You are saving for a skateboard. Your aunt gives you $45 to start, and you save $3 each
nekit [7.7K]

Answer:

$63

Step-by-step explanation:

You have the constant, $45. You then receive $3 each week. This can be written at $45 + $3w, where w is the number of weeks. So in this case, we need to find out how much money you will have after 6 weeks. We just need to plug in 6 weeks into the equation. The new equation will now be $45 + $3(6).

3 times 6 is $18.

$45 + $18 will give you a final answer of $63.

How do I solve this?
Norma-Jean [14]

Answer:

Step-by-step explanation:

Base = 25 ft

height = 8 ft

Area of triangle = \frac{1}{2}*base * height\\\\

                           = \frac{1}{2}*25 *8\\\\= 25 * 4\\\\= 100 ft^{2}
