Hello from MrBillDoesMath!

Answer: factor = 4

Discussion:

Look at the sequence of numbers

1/64, 1/16, 1/4, 1, 4

It's seems clear that multiplying a term by 4 gives the next term in the sequence.

Thank you,

MrB

Let u= <4,3>. Find the unit vector in the direction of u, and write your answer in component form.

aksik [14]

Take the vector u = <ux, uy> = <4, 3>.

Find the magnitude of u:

||u|| = sqrt[ (ux)^2 + (uy)^2]

||u|| = sqrt[ 4^2 + 3^2 ]

||u|| = sqrt[ 16 + 9 ]

||u|| = sqrt[ 25 ]

||u|| = 5

To find the unit vector in the direction of u, and also with the same sign, just divide each coordinate of u by ||u||. So the vector you are looking for is

u/||u||

u * (1/||u||)

= <4, 3> * (1/5)

= <4/5, 3/5>

and there it is.

Writing it in component form:

= (4/5) * i + (3/5) * j

I hope this helps. =)

14. f(x) = -x4 + x² + 4; x = -1

natali 33 [55]

Answer:

f(-1) = 4

Step-by-step explanation:

See below for the synthetic division tableau. The remainder is 4, hence ...

f(-1) = 4

___

IMO, in this function it is far easier just to substitute -1 for x. Since the only terms are of even degree, the value of f(-1) is the sum of the coefficients:

f(-1) = -1 +1 +4

f(-1) = 4

The equation y = 19.43x +609.077 is the equation of the regression line that predicts the number of people attending a county fa

atroni [7]

Answer:

1,114 people

Step-by-step explanation:

The equation $y=19.43x+609.077$ is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.

To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.

From 2000 to 2026,

$2026-2000=26yrs$

have passed.

The expected number who will attend the fair in 2026 is

$y=19.43*26+609.077$

$y=1114.26$

To the nearest whole number 1,114 people will attend in 2026
