one zero of f(x)=x^3-2x^2-5x+6 is 2 what are the zeros of the function

Step-by-step explanation:
Step-by-step explanation:
one zero of f(x)=x^3-2x^2-5x+6 is 2 what are the zeros of the function
the following polynomials have the function
f(x)=x^3-2x^2-5x+6
note 2 is not a zero of the function
but x=-2
to find the other zeros we say
f(x)/x+2=x^3-2x^2-5x+6/(x+2)
we have the quadratic equation
x^2-4x+3
factorizing the above, using factorization method
(x^2-3x-x+3)
(x^2-3x)(-x+3)
x(x-3)-1(x-3)
(x-1)(x-3)
x=1, x=3
the zeros of the function are
x=-2, x=1,x=3
substituting the values back into the function
we have zero
f(1)=1^3-2(1)^2-5(1)+6
F(1)=0
Answer:
-1 and -3 are the other zeroes

What is the area of this face ?
Answer: The area of the face is 15 sq. in.
Step-by-step explanation: We are given to find the area of the yellow-coloured face in the figure.
The area of the coloured face is equal to the area of one face of a cube of side 4 in MINUS the area of one face of a cube of side 1 inch.
The area of one face of a cube of side 4 in is given by
[tex]A=\textup{area of a square of side length 4 in.}=4\times 4=16\textup{ sq. in.}[/tex]
and the area one face of a cube of side 1 in is given by
[tex]a=\textup{area of a square of side length 1 in.}=1\times 1=1\textup{ sq. in.}[/tex]
Therefore, the area of the coloured face will be
[tex]Area=A-a=16-1=15\textup{ sq. in.}[/tex]
Thus, the area of the face is 15 sq. in.
The area of the face which is indicated in the figure is 15 in².
Use the concept of quadrilateral defined as:
Convex and concave are the two main forms. Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.
For big cube:
length of sides = 4 in
Area of one face = 4x4 in²
Area of one face = 16 in²
For small cube:
length of sides = 1 in
Area of one face = 1x1 in²
Area of one face = 1 in²
Since we can see that
The area of one face of a small cube coincides with the face of the big cube.
Therefore,
We have to remove the area of one face of the small cube from the big cube,
So, the area of the face indicated in the figure is,
(16 - 1) in² = 15 in²
Hence,
The area of the required face is 15 in²

A farmer grows two types of grain in his fields. He has a seed budget of $15,000.00 and has spent $5,800.00 to plant wheat seed so far. If barley seed costs $53.00 per acre to plant, what is the maximum number of acres of barley the farmer can plant and still be under budget?
A.283 acres
B.109 acres
C.173 acres
D.174 acres
Answer:
The answer is option D.
Step-by-step explanation:
Total seed budget is = $15000
Amount paid for wheat seeds = $5800
So, amount left is = [tex]15000-5800=9200[/tex]
Now, lets suppose the number of acre of land to be planted by barley seeds be = x
Barley seed costs = $53 per acre.
This means for 53x acres $9200 will be used.
Therefore, [tex]x=\frac{9200}{53}[/tex] = 173.58 acres ≈ 174 acres

Find the weighted average of these values
Value Weight
5.00 75.0 %
6.00 15.0 %
7.00 10.0 % ...?
To find the weighted average of given values, multiply each value by its weight, sum the results, yielding a weighted average of 5.35.
Explanation:The question is asking to find the weighted average of given values with their corresponding weights. To calculate a weighted average, each value is multiplied by its weight, and then the results are summed up. The formula used is \(Weighted\ Average = (Value_1 \times Weight_1) + (Value_2 \times Weight_2) + \cdots + (Value_n \times Weight_n)\).
Applying the given values and weights:
\(5.00 \times 75.0\% = 3.75\)\(6.00 \times 15.0\% = 0.90\)\(7.00 \times 10.0\% = 0.70\)Summing the results: \(3.75 + 0.90 + 0.70 = 5.35\).
Therefore, the weighted average of these values is 5.35.
The weighted average of the item is 5.35 weight units
The steps used to find the weighted average are as follows;
The weighted average is a technique or method used to find the average of a list of items, where the contribution of each item to the sum of the measurements are different or proportional to a specified measurement of the quantity
The mass and percentage by weight of the items indicates that we get;
The contribution of the item with a value of 5.00 is; 5 × 75% = 3.75
The contribution of the item with a value of 6.00 is; 6 × 15% = 0.9
The contribution of the item with a value of 7 is; 7 × 10% = 0.7
The weighted average of the substance is therefore; 3.75 + 0.9 + 0.7 = 5.35

. If you saved $2.00 on january 1, $4.00 on february 1, $8.00 on march 1, $16.00 on april 1, and so on. how much money would you save in one year?
By following a pattern of doubling the saved amount each month, the total amount saved in one year would be approximately $8190.00.
Use the concept of geometric sequence defined as:
A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding words. This ratio is regarded as one of the geometric sequence's frequent ratios.
Amount saved on January 1: $2.00
Amount saved on February 1: $4.00
Amount saved on March 1: $8.00
Continuing the pattern, the saved amount on April 1 would be $16.00
Since it can be seen that,
The pattern is that the saved amount doubles each month.
Therefore,
To calculate the total amount saved in one year,
Sum up the amounts for each month.
In this case, it would be
$2.00 + $4.00 + $8.00 + $16.00 + $32.00 + $64.00 + $128.00 + $256.00 + $512.00 + $1024.00 + $2048.00 + $4096.00 = $8190
Hence,
The saved amount in one year is $8190
