Dividing polynomials
(12x5+4x4-24x²-8x) + (3x + 1)
Answer:
Any quotient of polynomials a(x)/b(x) can be written as q(x)+r(x)/b(x), where the degree of r(x) is less than the degree of b(x). For example, (x²-3x+5)/(x-1) can be written as x-2+3/(x-1).
9th term of 25,150,900
Answer: The 9th term is 41990400
Step-by-step explanation:
As we can see here 25, 150, 900 to find the common ratio i'll divide 150 by 25 which gives me 6
to 25 times 6 is 150
150 times 6 is 900

what is the probability that maximum speed differs from the mean value by at most 2.5 standard deviations? (round your answer to four decimal places.)
The probability that maximum speed differs from the mean value by at most 2.5 standard deviations is 0.8473
Let the required probability that the maximum speed of mopeds differs from the mean speed by 2.5 standard deviations be given by P(U±2.5).
Mean speed U =46.7km/hr
P(46.7±2.5) = (44.2<= X <=49.2)
= P( 44.2<= Z <= 49.2)
= P(44.2 - 46.7/1.75 <= Z <= 49.2- 46.7/1.75)
= P( - 1.4286 <= Z <= 1.4285)
= P(1.4285) - P(-1.4285)
= P(1.43 ) - P(-1.43)
= 0.92364 - 0.07636

Let's determine the statement which is not a characteristic of the linear parent function.
The linear parent function has the form:
[tex]y=x[/tex]We have the graph below:
The function has the following properties:
• The line goes through the origin.
,• It has a range of all real numbers
,• It has a domain of all real numbers
,• It has a slope of 1.#
Therefore, the statement which is not a characteristic of the linear parent function is:
• The range is positive real numbers (y > 0).
ANSWER:
• A. The range is positive real numbers (y> 0)
a solid cube has side length 3 inches. a 2-inch by 2-inch square hole is cut into the center of each face. the edges of each cut are parallel to the edges of the cube, and each hole goes all the way through the cube. what is the volume, in cubic inches, of the remaining solid?
The volume of remaining solid is 7 in³.
What is volume of cube?The whole three-dimensional area occupied by a cube is its volume.
A cube is a solid 3-D object with six square faces and equal-length sides.
The cube is one of the five platonic solid shapes and is also referred to as a regular hexahedron.
The cubic units are used to represent the cube's volume.
Imagine performing each cut individually.
A box 2*2*3 is eliminated in the initial cut. Two boxes with dimensions of 2*2*0.5 are removed during the second cut, and the third cut eliminates the same number of boxes on the final two faces.
Therefore, the sum of all cuts is 12 + 4 + 4 = 20.
∴Volume of rest of cube = 3³-20
= 7 in³

The value of the equation d = 4n - 2 for n is (d + 2) ÷ 4.
Given data, d = 4n - 2
For finding the value of n first add 2 to both the side,
d + 2 = 4n - 2 + 2
d + 2 = 4n
Now, divide 4 into both sides of the equation:
(d + 2) ÷ 4 = 4n ÷ 4
(d + 2) ÷ 4 = n
∴ The value of n after solving the equation d = 4n - 2 is (d + 2) ÷ 4.

Explanations:
Let the money borrowed be the Principal, P = $200

Number of years, T = 12 years
The total amount to pay back will be:
Amount = Principal + Interest
Let us calculate the Interest, using the formula:
[tex]\begin{gathered} \text{Interest = }\frac{PRT}{100} \\ \text{Interest = }\frac{200\times2\times12}{100} \\ \text{Interest = 2}\times2\times12 \\ \text{Interest = 48} \end{gathered}[/tex]Interest = $48
