Which polynomial represents (6 x 2 −x−9)(4x−7)?
nydimaria [60]

Answer:

The answer to your question is 24x³ - 46x²- 28x + 63

Step-by-step explanation:

Data

               (6x² - x - 9)(4x - 7)

Process

1.- Multiply 4x by the three terms of the first polynomial

           (6x² - x - 9)(4x) = 24x³ - 4x² - 36x

2.- Multiply -7 by the three terms of the first polynomial

           (6x² - x - 9)(-7) = -42x² + 7x + 63

3.- Add both result

           24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63

A bus went halfway from a village to a city at a certain speed. Then it stopped in traffic for an hour. In order to catch up the
k0ka [10]
We have to assume that the speed before being stuck was sufficient to get to the destination on time had there been no delay. Call that speed "s" in km/h.

Since 200 km is "halfway", the total distance must be 400 km.

time = distance / speed
total time = (time for first half) + (delay) + (time for second half)

400/s = 200/s + 1 + 200/(s+10) . . . .times are in hours, distances in km
200/s = 1 + 200/(s+10) . . . . . . . . . . subtract 200/s
200(s+10) = s(s+10) +200s . . . . . . .multiply by s(s+10)
0 = s² +10s - 2000 . . . . . . . . . . . . . .subtract the left side
(s+50)(s-40) = 0
Solutions are s = -50, s = 40

The speed of the bus before the traffic holdup was 40 km/h.

An adult can lose or gain two pounds of water in the course of a day. Assume that the changes in water weight are uniformly dist
Levart [38]

Answer:

Standard deviation of the weight over a day is 1.15

Step-by-step explanation:

Since it is given that water weight is uniformly distributed between -2 to 2.  

So applying formula for variance of uniformly distribution as follows,  

variance=\dfrac{\left (b-a\right )^{2}}{12}

From the given data, values of a and b is , a=-2, b=2..

Substituting the values,  

variance=\dfrac{\left (2-\left (-2 \right )\right )^{2}}{12}

Now, -\left ( -2 \right )=2

variance=\dfrac{\left (2+2\right )^{2}}{12}

variance=\dfrac{\left (4\right )^{2}}{12}

variance=\dfrac{16}{12}

Dividing the fraction by 4,

variance=\dfrac{4}{3}

So, the value of variance is \dfrac{4}{3}

The formula for standard deviation is given as,

Standard\:deviation=\sqrt{variance}

Substituting the value,

Standard\:deviation=\sqrt{\dfrac{4}{3}}

Standard\:deviation=1.15470

Rounding to 2 decimal places,

Standard\:deviation=1.15

So, the value of standard deviation is 1.15.
