How many more miles is it to travel to Jakarta then to London

Tcecarenko [31]

It all depends where you start from, and what route you take.

For me, if I take the shortest possible route, then it's 3,956 miles to London
and 9,809 miles to Jakarta. So for me, Jakarta is 5,853 miles farther.

But if you're starting from, say, Singapore, then London is 6,192 miles
farther away than Jakarta.

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s

sergij07 [2.7K]

Answer:

The polynomial function is $P(x) = x^4-35x^2+180x-416.$

Step-by-step explanation:

A polynomial function is completely determined by its roots, up to a constant factor. So, if we want that $x_1=4$ , $x_2=-8$ and $x_3=2+3i$ be roots of the polynomial P, we can write it as

$P(x)= (x-x_1)(x-x_2)(x-x_3)=(x-4)(x+8)(x-(2+3i)) = (x^2+4x-32)(x-(2+3i)).$

Now, notice that the factor $x^2+4x-32$ has real coefficients, while the other one don't. So, we need to ‘‘eliminate’’ the complex coefficients that will appear. This can be done adding other complex root to the polynomial: the conjugate of $x_3$ : 2-3i. Then,

$P(x) = (x^2+4x-32)(x-(2+3i))(x-(2-3i)).$

Expanding the above expression we obtain the desired polynomial

$P(x) = x^4-35x^2+180x-416.$

Recall that P(x) must have three roots, and this implies that P has at least degree 3. As we had to add a new root in order to obtain real coefficients, the degree of P must be at least 4. With this reasoning we assure the minimal degree.

Find the missing measure for a right circular cone given the following information.. . Find h if r = 5 and V = 100.. . a)4. b)12

Alex Ar [27]

Volume = pi r^2 (h/3)
100 = 3.14 (25) (h/3)
100 = 78.5 (h/3)
h= 3.82
or
h= 4
Thus,
Best answer is option a) 4.
