Answer:

7. (4x +10)/(x^3 +3x^2 -16x -48)

9. -320/93

Step-by-step explanation:

7. As with adding any fractions, first you find a common denominator. When the fractions are rational expressions, it often helps to factor the denominators.

6/(x^2 -16) -2/(x^2 -x -12) = 6/((x -4)(x +4)) -2/((x -4)(x +3))

= (6(x +3) -2(x +4))/((x -4)(x +3)(x +4)) . . . . . using a common denominator

= (6x +18 -2x -8)/((x -4)(x +3)(x +4))

= (4x +10)/((x^2 -16)(x +3))

= (4x +10)/(x^3 +3x^2 -16x -48)

_____

9. First you simplify the denominator:

2/25 -5/16 = (2·16 -5·25)/(25·16) = -93/400

Then you perform the division. This can be done by multiplying by the inverse of the denominator.

(4/5)/(2/5 -5/16) = (4/5)·(-400/93) = -320/93

A ball is thrown in the air from a platform that is 96 feet above ground level with an initial vertical velocity of 32 feet per
pishuonlain [190]

Answer:

y = -16 (x - 1)^2 + 112

The object lands on the ground in approximately 3.6s

Explanation:

The equation given is that of a parabola.

Now the maximum (local) point of a parabola is the vertex. Therefore, if we want to rewrite our function in the form that would be used to find the maximum height, then that form must be the vertex form of a parabola.

The vertex form of a parabola is

y=a(t-h)^2+k

where (h, k) is the vertex.

The only question is, what is the vertex for our function h(t)?

Remember that if we have an equation of the form

y=ax^2+bx+c

then the x-coordinate of the vertex is

h=-\frac{b}{2a}

Now in our case b = 32 and a = -16; therefore,

h=\frac{-32}{2(16)}=1

We've found the value of the x-coordinate of the vertex. What about the y-coordinate? To get the y-coordinate, we put x = 1 into h(t) and get

k=-16(1)+32(1)+96=112

Hence, the y-coordindate is k = 112.

Therefore, the vertex of the parabola is (1, 112).

With the coordinates of the vertex in hand, we now write the equation of the parabola in vertex form.

h(t)=a(t-1)^2+112

The only problem is that we don't know what the value of a is. How do we find a?

Note that the point (0, 96) lies on the parabola. In other words,

h(0)=-16(0)^2+32(0)+96=96

Therefore, the vertex form of the parabola must also contain the point (0, 96).

Putting in t = 0, h = 96 into the vertex form gives

96=a(0-1)^2+11296=a+112

subtracting 112 from both sides gives

a=-16

With the value of a in hand, we can finally write the equation of the parabola on vertex form.

\boxed{h\mleft(t\mright)=-16\left(t-1\right)^2+112.}

Now when does the object hit the ground? In other words, for what value of t is h(t) = 0? To find out we just have to solve the following for t.

h(t)=0.

We could either use h(t) = -16t^2 + 32t + 96 or the h(t) = -16(t - 1)^2 + 112 for the above equation. But it turns out, the vertex form is more convenient.

Thus we solve,

-16\left(t-1\right)^2+112=0

Now subtracting 112 from both sides gives

-16(t-1)^2=-112

Dividing both sides by -16 gives

(t-1)^2=\frac{-112}{-16}(t-1)^2=7

taking the square root of both sides gives

t-1=\pm\sqrt{7}

adding 1 to both sides gives

t=\pm\sqrt{7}+1

Hence, the two solutions we get are

t=\sqrt{7}+1=3.6t=-\sqrt{7}+1=-1.6

Now since time cannot take a negative value, we discard the second solution and say that t = 3.6 is our valid solution.

Therefore, it takes about 3.6 seconds for the object to hit the ground.
