Answer:

D) 22534 m

Step-by-step explanation:

The figure forms a Z shape where the top line and bottom line are parallel. Therefore the angle with the coastline, inside the triangle will be 16.5°.

We have to find the hypotenuse which is the side opposite to the 90 degree angle.

Now this can be solved through sin formula

Step 1: Write all the data

Angle = 16.5°

Opposite = 6400

Hypotenuse = ?

Step 2: Use the sin formula

Sin (Angle) = Opposite/Hypotenuse

Sin (16.5) = 6400/Hypotenuse

Step 3: Solve

Hypotenuse = 6400/sin(16.5)

Hypotenuse = 22533.99 rounded off to 22534 m

The jet has to fly 22534 m before it reaches the coastline.

Therefore, option D is the correct answer.

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

Elodia [21]

2+5i is complex, and MUST be accompanied by its conjugate, 2-5i.

Thus, the factors of this 4th degree poly are (x-4)(x+8)(x-2-5i)(x-2+5i).

Multiply this out to obtain the poly in question. Then arrange the powers of x in descending order, beginning with x^4.

Given that lim x→1 (5x − 3) = 2, illustrate definition 2 by finding values of δ that correspond to ε = 0.1, ε = 0.05, and ε = 0.

kow [346]

$\displaystyle\lim_{x\to1}(5x-3)=2$

is to say that for any $\varepsilon>0$ , we can find $\delta>0$ such that $0$ implies $|(5x-3)-2|$ .

To that end, we have

$|(5x-3)-2|=|5x-5|=5|x-1|$

which means that if $\varepsilon=0.1$ is given, then we can choose $\delta=\dfrac{0.1}5=0.02$ ; if $\varepsilon=0.05$ , then $\delta=\dfrac{0.05}5=0.01$ ; if $\varepsilon=0.01$ , then $\delta=\dfrac{0.01}5=0.002$ .

Serga [27]

Answer:

0.0159

Step-by-step explanation:

Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.

Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)

The plane is overbooked if more than 150 show up

i.e. less than 2 do not show up

Hence the probability that the airline overbooked this flight

= $P(X$
