Solve. 9 m 3 − 27 m 2 − 252 m = 0

Mathematics
1 answer:
Brrunno [24]2 years ago
4 0

Answer:

m = 0

m = 7

m = -4

Step-by-step explanation:

\sf 9m^3-27m^2-252m=0

Divide by 9:

\sf \implies m^3-3m^2-28m=0

Factor out common term m:

\sf \implies m(m^2-3m-28)=0

Factor expression in parentheses:

\sf \implies m(m-7)(m+4)=0

Therefore,

\sf \implies m=0

\sf \implies m-7=0 \implies m=7

\sf \implies m+4=0 \implies m=-4

Which of the following equations represent nonlinear functions?
s2008m [1.1K]

y=5x^2+7 is Non-Linear Functions

Option B is correct option.

Step-by-step explanation:

We need to identify Non-Linear Functions from the equations given.

First we will define Non-Linear Functions

<u>Linear Functions</u>

A function having exponent of variable equal to 1 or of the form y=c, where c is constant is called linear function.

<u>Non-Linear Functions</u>

A function that has variable having power greater than 1 (i.e 2 or above) is called non-linear function.

So, from all the options given, only Option B has power greater than 1 i.e 2. All remaining options are linear functions.

So, y=5x^2+7 is Non-Linear Functions

Option B is correct option.

Which measure of variation is found by placing the data in ascending order and subtracting the lowest value from the highest val
igomit [66]

Answer:

Range

Step-by-step explanation:

The range of a given set of data is the difference between the largest value and the smallest value in the data. For convenience and ease in the calculation, it is advisable to place the data in ascending order.

For example, given the following set of data:

4,9,5,6,2

To find the range;

<em>=> First arrange the data in ascending order</em>

2,4,5,6,9

<em>=> Find the smallest and largest numbers and then find their difference.</em>

Since the data has been arranged, it is obvious to see that the smallest number is <em>2</em> and the largest number is <em>9.</em>

Therefore the;

range = 9 -2 = 7
