What are the real or imaginary solutions of the polynomial x^3=9x​
dem82 [27]

Hello from MrBillDoesMath!

Answer:

 x = 0, +\-3


Discussion:

x^3 = 9x              => subtract 9x from both sides

x^3 - 9x = 0         => factor x from both terms

x(x^2-9) = 0        => x = 0 or x^2 - 9 = 0

x = 0, +\-3

Thank you,

MrB

The course grade in a statistics class is the average of the scores on five examinations. Suppose that a student's scores on the
nadya68 [22]

Answer:

84 is the highest possible course average

Step-by-step explanation:

Total number of examinations = 5

Average = sum of scores in each examination/total number of examinations

Let the score for the last examination be x.

Average = (66+78+94+83+x)/5 = y

5y = 321+x

x = 5y -321

If y = 6, x = 5×6 -321 =-291.the student cannot score -291

If y = 80, x = 5×80 -321 =79.he can still score higher

If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.

If y= 100

The average cannot be 100 as student cannot score 179(maximum score is 100)

Trucks are delivering gravel to a construction site each truck hold 7.5 cubic yards of gravel. The weight of 1 cubic yard of gra
Romashka-Z-Leto [24]
The first thing you must do is to calculate the weight of the gravel (w) that the truck holds (7.5 yards³). So, you have:

 If the weight of 1 yard³ is 1.48 tons, then the weight of 7.5 yards³ is:

 w=7.5x1.48 tons
 w=11.1 tons

 The problem says that the gravel will be placed in containers that each hold 3.7 tons of gravel,so, If they need 1 cotainer to place 3.7 tons, how many containers they need to place 11.1 tons?

 1 container-------3.7 tons of gravel
                 x-------11.1 tons of gravel

 x=(11.1x1)/3.7
 x=11.1/3.7
 x=3 containers

 H<span>ow many containers of this size are needed to hold all the gravel from one truck?
</span>
 The answer is: 3 containers.
