Work out an approximate solution to x^3+2x-1=0 use the iteration...... Help please!!!!?????
Approximate solutions are the estimate values of an equation
The approximate solution of the equation is x = 0.45
How to determine the approximate solutionThe equation is given as:
[tex]x^3 + 2x- 1= 0[/tex]
The iteration is given as:
[tex]x_{n+1} = \frac{1}{x_n^2 + 2}[/tex]
To start with, we have:
[tex]x_1 = 1[/tex]
So, we have:
[tex]x_2 = \frac{1}{1^2 + 2} = \frac 13 =0.33333333[/tex]
The next iteration is:
[tex]x_3 = \frac{1}{0.33333333^2 + 2} = 0.47368421102[/tex]
The next iteration is:
[tex]x_4 = \frac{1}{0.47368421102^2 + 2} = 0.4495641344[/tex]
The next iteration is:
[tex]x_5 = \frac{1}{0.4495641344^2 + 2} = 0.45411035264[/tex]
The next iteration is:
[tex]x_6 = \frac{1}{0.45411035264^2 + 2} = 0.45326473189[/tex]
Notice that:
x5 and x6 have the same value to 2 decimal places.
i.e. [tex]x_5 \approx x_6 = 0.45[/tex]
Hence, the approximate solution of the equation is x = 0.45

Cardinal number of set A=1,2,3,4,0,7 is 6
Answer:
n(A) = 6
Step-by-step explanation:
Let consider a set A = {a, m, b, d, h}. There are five elements in the set. The no of elements in a set is known its cardinality. Since set A has five elements, its cardinality number is 5. The cardinality of the set A is denoted by n(A).
Hence, from the given information:
The set A = {1, 2, 3, 4, 0, 7} have a cardinality number of 6
n(A) = 6

Answer:
9-pack of hot dogs for $3.61
Answer:
Step-by-step explanation:
This is a question on the unit price. The better buy is the lower unit price. But that only works if you have 8 people to share the dogs with.
2 dogs cost 0.81
1 dog is 0.81/2 = 0.405 which you should write as 0.41
9 dogs are 3.61
1 dog is 3.61/9 = 0.401 what you (again) should be 0.41
Ever so marginally, you should pick the 2 dogs if there are only 2 people and 9 dogs if you are buying for a baseball team.

Kali had a total of 212121 balloons at her birthday party. The ratio of blue balloons to green balloons is shown in the tape diagram. How many blue balloons did Kali have at her party?
Answer:
Blue balloons = 12
Step-by-step explanation:
Total no of balloons = 21
Let us assume that the ratio of blue balloons to green balloons is 4:3.
Let there are 4x blue balloons and 3x green balloons.
ATQ,
4x+3x = 21
7x = 21
x = 3
Blue balloons = 4x
= 4(3)
= 12
Hence, she will have 12 blue balloons at her party.

An investor invested a total of $2100 in two mutual funds. One fund earned a 4% profit while the other earned a 2% profit. If the investor's total profit was $62, how much was invested in each mutual fund?
Answer:
x+y=2100
x(0.04) + y(0.02) = 62
(2100-y)(0.04)+ 0.02y = 62
84-0.02y = 62
22/0.02=y
y=1100
x=1000
What triangle congruence theorem could you use to
prove triangle ADE is congruent to triangle CBE?
Answer:
(ASA) Angle Side Angle
Step-by-step explanation:
Both triangles shown have the congruence line on an angle and an adjacent side. ASA proves congruence because in addition to the angle and side, the triangles ADE and CBE share the same angle on point E. Because the two lines are intersecting, their opposite angles are congruent and the triangles share the opposite angles.
The triangle congruence theorem that could be used to show that triangle ADE is congruent to triangle CBE is;
ASA Congruence theorem.
Looking at the given triangles we can say that;
∠AED = ∠CEB
This is because they are both vertically opposite angles and vertically opposite angles are equal.
Now, from the triangle, we are given that;
∠DAE = ∠BCE
We are also given that;
AE = CE
This means that we have 2 corresponding angles and 1 corresponding included side that are congruent.
Thus, the congruence theorem that this represents is ASA Congruence theorem.

On 1 September, Leila starts to go swimming every day.
She swims 30 lengths of the swimming pool every day. The swimming pool is 20m long.
Work out the date when Leila has swum a total of 10 km.
Answer:
22 November
Step-by-step explanation:
First we have to find the total length she swims in 1 day
= 2(length of the swimming pool) x no. of lengths she swims in 1 day
=2x30x20
=120m she covers in 1 day
10km = 10,000m
no of days= total distance/ distance she covers in 1 day
=10000/120

Answer:
12a) 4L - 6 = Perimeter
13) 4(6x + 9)
Step-by-step explanation:
for #12: two sides of the rectangle are referred to as L
The other two sides can be referred to as L-3 (these sides are the width, which are 3 less than the length)
Perimeter = sum of all sides; so, 2L + 2(L-3)
P = 2L + 2L - 6
= 4L - 6
Answer: 12. The expression is 2L+2(L-3)
13. The answer is 6x+9
Step-by-step explanation:
12. The perimeter of a rectangle is 2*length +2*width. So, in this case (when L is the length of the rectangle) the perimeter should be 2L+2(L-3). If you simplify you will get 4L-6.
13. The perimeter is just the value you get when all the sides of a shape are added. A square has 4 equal sides. So, just divide the perimeter, which in this case is (24x+36), by 4. You should get 6x+9.

Answer:
c
Step-by-step explanation:
I took the test and got it right
The correct equation that justifies why seven to the one-third power equals the cube root of seven is option C: [tex](7^{(1/3)})^3[/tex]=[tex]7^{(1/3 * 3)[/tex]=7.
C. Seven to the one-third power all raised to the third power equals seven to the one-third times three power equals seven.
Let's break down the steps:
Seven to the one-third power all raised to the third power:
[tex](7^{(1/3)})^3[/tex]
Using the property of exponents [tex](a^{(m*n)} = (a^m)^n)[/tex] to simplify:
[tex]7^{(1/3 * 3)[/tex]
The exponent 1/3 multiplied by 3 is equal to 1:
[tex]7^1[/tex]
Any number raised to the power of 1 is itself, so:
7
This justifies that [tex]7^{(1/3)[/tex] raised to the power of 3 is equal to 7.
Therefore, [tex]7^{(1/3)[/tex] is equal to the cube root of 7.

What is 7,459,82 rounded to the nearest whole number? (Remember : the whole number is in the ONES place)
Answer this please ASAP or NOW
Answer:
7,460
Step-by-step explanation:
Whole numbers are counting numbers like 0, 1, 2, 3, . . .. Whole numbers are positive integers including 0
When rounding a number to the nearest whole number, firstly check the first digit after the decimal point. If the first digit is less than 5 we don't round up, but if the first digit is 5 or greater we round up.
Given the number 7,459.82
We check, the first digit after the decimal point, since this digit is greater than 5 (i.e. 8) we round u to get 7,460

3x+4 = 4x+3 how many solutions are there
The equation 3x + 4 = 4x + 3 has one solution.
To determine the number of solutions for the equation 3x + 4 = 4x + 3, we can simplify and analyze the equation.
First, we can rearrange the equation by moving all the x terms to one side and the constant terms to the other side:
3x - 4x = 3 - 4
Simplifying further:
-x = -1
Next, we can multiply both sides of the equation by -1 to eliminate the negative sign:
x = 1
Therefore, we have found a single solution for x, which is x = 1. This means that when we substitute x = 1 into the original equation, both sides will be equal.
In summary, the equation 3x + 4 = 4x + 3 has one solution, which is x = 1. This can be verified by substituting x = 1 back into the equation and confirming that both sides are equal.
