The polynomial function with zeroes at -2, 0, and 3√2 is (x+2)(x-0)(x-3√2) = [tex](x+2)*(x-3\sqrt{2}) = x^3 - 3x\sqrt{2x} - 2x^2.[/tex]
The polynomial function with zeroes at -1, 3, and 2i is (x+1)(x-3)(x-2i) = [tex](x+1)(x-3)(x^2+4) = x^3 +x^2 - 11x -12[/tex]
A polynomial function is a function of the form f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0, where n is the degree of the polynomial and the a_i are constants. To find a polynomial function with zeroes at -2, 0, and 3√2, we can use the fact that if a polynomial function has a zero at x=c, then (x-c) is a factor of the polynomial. Therefore, we can write the polynomial function as [tex](x+2)(x-0)(x-3\sqrt{2}) = (x+2)x(x-3√2) = x^3 - 3x\sqrt{2x} - 2x^2[/tex].
In this case, we can see that x = -2, x = 0, x = 3√2 are the zeroes, so we know that (x+2), x and (x-3√2) are the factors of the polynomial.
Similarly, to find a polynomial function with zeroes at -1, 3, and 2i, we can use the fact that if a polynomial function has a zero at x=c, then (x-c) is a factor of the polynomial. Therefore, we can write the polynomial function as [tex](x+1)(x-3)(x-2i) = (x+1)(x-3)(x^2+4) = x^3 +x^2 - 11x -12[/tex]
In this case, we can see that x = -1, x = 3, x = 2i are the zeroes, so we know that [tex](x+1), (x-3), (x^2+4)[/tex]are the factors of the polynomial.
It is worth noting that (x-2i) is a zero of the polynomial, so (x-2i)(x+2i) = [tex]x^2[/tex]+4 is a factor of the polynomial and it is included in the polynomial..

How do you solve y =- 2x 6?.
We can find the solution of y = -2x + 6 by graphing the equation by plotting the intercepts of the equation.
Here we can solve the equation by calculating the x and y intercepts of the equation.
This is done by equating the other coordinate to 0 to get the intercept.
For the x-intercept, we will take y to be 0 to get
-2x + 6 = 0
or, 2x = 6
or, x = 3
Hence one intercept will be (3 , 0)
For the y-intercept, we will let x be 0 to get
y = 6
Hence getting the other intercept to be (0 , 6)
Now we can plot the graph by simply plotting these points and drawing a straight line passing through it
To get any unique solution, another equation needs to be plotted and the intersection point of the 2 lines will give us the required answer.

In the given Rhombus ABCD, the measure of side AE = 27.85.
What is Area of a Rhombus?Verify that the two diagonals are parallel to one another. The diagonal lines are parallel. A rhombus is what it is. The parallelogram is a rectangle, rhombus, and square since the diagonals are all congruent and perpendicular to one another.
Area can be used to determine the area of a rhombus because it is a parallelogram, and its area can be determined from the length of its base and perpendicular height.
Here, we construct an alternate formula for the area of a rhombus that uses the lengths of its diagonals. Find the length of the other diagonal if one of the diagonals is 8 units long. We already know how to compute the area of a rhombus using its diagonals: Area = (1/2) (diagonal1 diagonal2) 256 = (1/2) (8 diagonal2).

Fat food chain uing platic or tyrofoam in elling their product, make a 5 entence of the problematic ituation
Fast food chains that use plastic or styrofoam containers in selling their products are contributing to the global plastic pollution crisis. Styrofoam and plastic containers, which are not biodegradable, take up to 1000 years to decompose.
Every year, an estimated 8 million metric tons of plastic end up in the ocean, and the majority of it is from single-use plastic products such as those used by fast food chains. This plastic pollution is having a devastating effect on the environment, with marine life ingesting and becoming entangled in the plastic. In addition, the production of styrofoam and plastic containers is highly energy intensive and contributes to the emission of greenhouse gases. This is a problematic situation that needs to be addressed urgently.
The energy intensity of production for styrofoam and plastic containers can be calculated using the formula:
Energy Intensity (EI) = Energy Used (EU) / Output (O)
For example, if it takes 50 kWh of energy to produce a unit of output, the energy intensity of production would be 50 kWh/unit. This highlights the environmental impact of styrofoam and plastic containers, and the urgent need to reduce their use in fast food chains.

A triangular tract of farm land has sides of length 2.1 miles, 1.8
miles, and 2.7 miles. If a bag of fertilizer covers 0.2 square
miles, how many bags of fertilizer are needed to cover the area
of the triangle? Round your answer to the nearest whole
number. NEED THIS ASAP TYSM
Answer: we would need 7 bags of fertilizer to cover the area of the triangle.
Step-by-step explanation:
To find the area of a triangle, we can use Heron's formula. Heron's formula states that the area of a triangle can be found by taking the square root of the semi-perimeter multiplied by the difference of the semi-perimeter and each side length.
The semi-perimeter of the triangle is (2.1+1.8+2.7)/2 = 2.7
The area of the triangle is sqrt(2.7*(2.7-2.1)(2.7-1.8)(2.7-2.7)) = sqrt(2.70.60.9*0) = 1.35
Each bag of fertilizer covers 0.2 square miles, so we need to divide the area of the triangle by the area covered by each bag to find how many bags are needed: 1.35 / 0.2 = 6.75
Rounding up to the nearest whole number, we would need 7 bags of fertilizer to cover the area of the triangle.

At KFC, the kitchen taff baked 25 chicken leg and 50 wing. The taff had to prepare platter for an office lunch. If each platter will have the ame number of leg and wing, what i the greatet number of platter they can make?
So, each platter will have 25 legs and 25 wings.
To determine the greatest number of platters the kitchen staff can make, you need to find the least common multiple of 25 and 50. This is because each platter must have the same number of legs and wings, so you need to find the smallest number of legs and wings that can be divided evenly into both 25 legs and 50 wings.
The least common multiple (LCM) of 25 and 50 is 50. This means that the greatest number of platters the kitchen staff can make is 50/25 = 2 platters.

The rectangular prism's dimensions are 3:2:1 in terms of length, breadth, and height. The prism's length can be computed as 24 cm using its volume, 48 cm3, as input.
Volume = Length × Width × Height
48 cm3 = L × 2 × 1
L = 24 cm
A rectangular prism is a solid 3D object that has six faces, eight vertices and twelve edges. The length, width and height of a rectangular prism can be expressed in a ratio of 3:2:1 respectively. Knowing this ratio and the volume of the prism, which is 48 cm3, it is possible to calculate the length of the prism. To calculate the length of the prism, first the volume of the prism must be expressed in terms of the length. This can be done by using the formula Volume = Length × Width × Height. Therefore, 48 cm3 = L × 2 × 1. Solving this equation for L gives the length of the prism as 24 cm. Therefore, the length of the rectangular prism with a volume of 48 cm3 and a ratio of 3:2:1 is 24 cm.
