Use polynomial long division to divide 2x2 + 3x −1 by x + 4. What are the quotient and remainder?
Karo-lina-s [1.5K]

Step-by-step explanation:

2x - 5

x+4 / 2x^2 + 3x - 1

- 2x^2 + 8x

0 -5x - 1

- -5x - 20

0 19

Quotient = 2x - 5 + 19/x+4

Remainder = 19/x+4

About 250 million drivers are registered in the United States. While on a trip with her family, a student counted the number of
Lilit [14]
She could estimate that there would be about 148 million female drivers.

From her data, she found there were 118 females drivers out of the total 200 drivers that she counted.

That is 118 out of 200 or 0.59 or 59%.

Now, just take 59% of 250.

0.59 x 250 = 147.5 which rounds to 148.

find the angle between the vectors. (first find the exact expression and then approximate to the nearest degree. ) a=[1,2,-2]. B
SashulF [63]

Answer:

\theta = cos^{-1} (\frac{10}{\sqrt{9} \sqrt{25}})=cos^{-1} (\frac{10}{15}) = cos^{-1} (\frac{2}{3}) = 48.190

Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel

And the anfle is approximately \theta \approx 48

Step-by-step explanation:

For this case first we need to calculate the dot product of the vectors, and after this if the dot product is not equal to 0 we can calculate the angle between the two vectors in order to see if there are parallel or not.

a=[1,2,-2], b=[4,0,-3,]

The dot product on this case is:

a b= (1)*(4) + (2)*(0)+ (-2)*(-3)=10

Since the dot product is not equal to zero then the two vectors are not orthogonal.

Now we can calculate the magnitude of each vector like this:

|a|= \sqrt{(1)^2 +(2)^2 +(-2)^2}=\sqrt{9} =3

|b| =\sqrt{(4)^2 +(0)^2 +(-3)^2}=\sqrt{25}= 5

And finally we can calculate the angle between the vectors like this:

cos \theta = \frac{ab}{|a| |b|}

And the angle is given by:

\theta = cos^{-1} (\frac{ab}{|a| |b|})

If we replace we got:

\theta = cos^{-1} (\frac{10}{\sqrt{9} \sqrt{25}})=cos^{-1} (\frac{10}{15}) = cos^{-1} (\frac{2}{3}) = 48.190

Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel

And the anfle is approximately \theta \approx 48
