What formula should be used when factoring the expressionn x^3+27

Mathematics
1 answer:
kobusy [5.1K]3 years ago
5 0

x³ + 27 which can be written as x³ + 3³

It is in the form of a³ + b³ = ( a + b) ( a² - ab + b²)

so

x³ + 3³

= (x+ 3) (x² - x * 3 + 3²)

= ( x + 3 ) ( x² - 3x + 9)

Hope this helps you.

A rocket is launched at t = 0 seconds. Its height, in meters above sea-level, is given by the equation
gogolik [260]

Answer:

Step-by-step explanation:

In order to find out how long it takes for the rocket to hit the ground, we only need set that position equation equal to 0 (that's how high something is off the ground when it is sitting ON the ground) and factor to solve for t:

0=-4.9t^2+112t+395

Factor that however you are factoring in class to get

t = -3.1 seconds and t = 25.9 seconds.

Since time can NEVER be negative, it takes the rocket approximately 26 seconds to hit the ground.

Assignment: generating frequencies for compound events investigation fill out this table to show the sample space for a roll of
m_a_m_a [10]

Total 36 outcomes are possible on rolling two dices simultaneously

A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes that depends on the experiment

A dice has 6 possibilities (1,2,3,4,5,6) , thus two when dices thrown together will have 36 outcomes in it's sample space. It's sample space is shown in picture attached below.

The admission fee at an amusement park is $2.50 for children and $5.40 for adults. On a certain day, 324 people entered the park
zheka24 [161]

Answer:

  • 124 children
  • 200 adults

Step-by-step explanation:

It usually works well to let a variable represent quantity of the highest-value contributor. Here, that is the quantity of adult tickets.

Let "a" represent the number of adult tickets sold. Then (324-a) is the number of admission fees for children. The total revenue is ...

  5.40a +2.50(324 -a) = 1390

  2.90a +810 = 1390 . . . . eliminate parentheses

  2.90a = 580 . . . . . . . . . subtract 810

  a = 200 . . . . . . . . . . . . . .divide by 2.90

The number of children admitted was 124; the number of adults admitted was 200.
