What are the roots of the polynomial equation x^3-7x=6x-12? a. –6, 6
b. –4, 1, 3
c. –3, –1, 4
d. 1, 3

Answers

Answer 1

Answer: Hello,

Answer B

P(x)=x^3-13x+12
P(1)=1-13+12=0 ==>1 is root
P(3)=3^3-13*3+12=0 ==>3 is root
P(-4)=(-4)^3-13*(-4)+12=0 is root

P(x)=(x-1)(x-3)(x+4)

What is the excluded value of x for the expression 1/x-6? A.) x = –6
B.) x = –1
C.) x = 1
D.) x = 6

Answers

Answer:

Option (d) is correct.

The excluded value of x for the given expression $(1)/(x-6)$ is 6.

Step-by-step explanation:

Given : Expression $(1)/(x-6)$

We have to find the excluded value of x for the given expression $(1)/(x-6)$ .

Consider the given expression $(1)/(x-6)$

Since, when x = 6 then the value of denominator becomes 0 and also, the expression $(1)/(6-6)$ becomes $(1)/(0)$ , which makes the expression not defined.

Thus, The excluded value of x for the given expression $(1)/(x-6)$ is 6.

the excluded value of x for the expression 1/x-6 is
D.) x = 6

teacher asked her students write down the number of hours studied rounded to the nearest half hour. she complies the results in develops the probability distribution below for randomly selected student. what is the mean of the probability distribution

Answers

Answer:

1.5

Step-by-step explanation:

The question is incomplete due to the probability distribution table, investigating you can find it so I will attach it.

Having the table, we need to find the mean of the probability distribution, which is defined as the sum of the product of probability and value of random distribution, that is:

M = Sum (xi) * P (xi)

We replace:

M = 0.5 * 0.07 + 1 * 0.2 + 1.5 * 0.46 + 2 * 0.2 + 2.5 * 0.07

M = 1.5

Therefore, the mean of the given table is 1.5

If ladybugs have 30 cm x 10 cm rectangles for pumpkins each pumpkin needs exactly 25 square centimeters of space how many pumpkins can they plant

Answers

To calculate how many pumpkins can be planted in a given space, you need to know the total area available and the area required for each pumpkin.

You mentioned that each pumpkin needs a rectangular space of 30 cm x 10 cm, which is an area of (30 cm) * (10 cm) = 300 square centimeters.

Now, if you have the total area available, you can divide it by the area required for each pumpkin:

Total Area Available / Area Required for Each Pumpkin = Number of Pumpkins

If you provide the total area available, I can help you calculate how many pumpkins can be planted.

Ans 12

Explaination
Area = 30*10cm= 300cm^2
Each pumpkin= 25cm^2
No. Of pumpkin that can be planted= 300/25= 12
