Answer:

$2x(3x^2-2x-1)$

Step-by-step explanation:

Area of a rectangle is simply length times width

{ $6x^2-4x-2$ } * x would be the area

That can be simplified to

$6x^3-4x^2-2x$

Which can be further simplified to

$2x(3x^2-2x-1)$

Si f(x) = 1/2x^2-(1/4x+3),¿cuál es el valor de f(8)?<br> (3) 27<br> (2) 17<br> (4) 33<br> (1) 11

gavmur [86]

Answer:

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = $\frac{1}{2}$ × 8² - ( $\frac{1}{4}$ × 8 + 3)

= $\frac{1}{2}$ × 64 - (2 + 3)

= 32 - 5

= 27

Write the equation of the line that passes. Throught the point (-2,1)and (0,8)put your aswer in fully reduce point slope form un

Soloha48 [4]

Answer:

Step-by-step explanation:

first, we need to find the slope

slope = (y2 - y1) / (x2 - x1)

(-2,1)...x1 = -2 and y1 = 1

(0,8)...x2 = 0 and y2 = 8

now sub

slope = (8 - 1) / (0- (-2) = 7/(0 + 2) = 7/2

point slope form : y - y1 = m(x - x1)

using point (-2,1)....x1 = -2 and y1 = 1

slope(m) = 7/2

now sub

y - 1 = 7/2(x - (-2) =

y - 1 = 7/2(x + 2) <==== here is one answer

y - y1 = m(x - x1)

using point (0,8)...x1 = 0 and y1 = 8

slope(m) = 7/2

now sub

y - 8 = 7/2(x - 0) <===== another possible answer

A sequence is defined recursively by the formula f(n+1)=-2f(n). The first term of the sequence is -1.5. Whis is the next term in

podryga [215]

We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)

My brother told me he will give me $.25 per day for 10 days OR he will give me $.01 then give me double the following day for 10

NARA [144]

Answer:

you will get more money if he gives you 1 cent per day then doubles it

Step-by-step explanation:

if your brother gives you 25 cents per day, at the end of 10 days you will have $2.50

if he gives you 1 cent per day then doubles it, this will be your daily earnings:

day 1- 0.01

day 2- 0.02

day 3- 0.04

day 4- 0.08

day 5- 0.16

day 6- 0.32

day 7- 0.64

day 8- 1.28

day 9- 2.56

day 10- 5.12

then when you add all of this up, you would recieve 10.23 cents at the end of day 10
