Answer:

x = −2 or x = 4.23606797749979 or x = −0.2360679774997898

Step-by-step explanation:

Subtract x^3-2x^2-9x-2 from both sides.

0 − (x3−2x2−9x−2) = x3−2x2−9x−2 − (x3−2x2−9x−2)

−x3+2x2+9x+2=0

Factor left side of equation.

(−x−2)(x2−4x−1)=0

Set factors equal to 0.

−x−2=0 or x2−4x−1=0

Step-by-step explanation:

When drawing a dot, the steps are;

i) The data set (the list of numbers to be presented in the dot plot) are arranged in increasing order from left to right, with thee lowest value on the left and the highest value located at the right of the list

ii) The five boundary values are listed as follows;

The Minimum and Maximum Values

1) The minimum value is the lowest number in the list, which is the first number from the left

2) The maximum value is the final number on the right of the list

3) The Median, Q₂

The median number is the number which divides the data arranged in increasing number, into two equal parts

The First Quartile and Third Quartile

The numbers are divided from the median, such that the Lower half is to the left of the Median, and the Upper half is to the right of median

4) The First Quartile, Q₁ = The median of the Lower half

5) The Third Quartile, Q₂ = The median of the Upper half

=> Whenever the denominator is 0, A is undefined, neither a positive number or negative number

Hope this helps!

Would a teaspoon be a good way to measure the capacity of a milk carton
Natali [406]
No, a teaspoon is too small to measure the capacity of a milk carton. You would use a quart to measure the capacity of a gallon.

Hope this helps :)

a beverage is made by mixing 3 parts of water with 5 parts of fruit juice how many parts of water are mixed with 1 part on fruit
Fittoniya [83]

Answer:

\frac{3}{5}=0.6

Step-by-step explanation:

Given the initial ratio of 3 parts water to 5 parts fruit juice, you can set up a proportion (equivalent ratios) to determine the amount of water needed with just 1 part of fruit juice:

\frac{water}{fruit}=\frac{3}{5}=\frac{x}{1}

cross multiply: 5x = 3

divide: 5x/5 = 3/5 or x = 3/5

3/5 = 0.6 parts water
