Answer:

  • See below

Step-by-step explanation:

Corresponding sides have equal ratios:

  • OB / OP = OK / OS

Let the y-coordinate of the point K is y, then we have:

  • 5 / 8 = y / - 12
  • y = - 12*5/8
  • y = - 7.5

Note, taken the coordinates of end points not the absolute distance.

The coordinates of the point K are (0, - 7.5)

The scale factor is:

  • k = OP / OB = 8/5 = 1.6 or
  • k = OS / OK = -12 / -7.5 = 1.6

Answer:

K = (0, -7.5)

Scale factor = 1.6

Step-by-step explanation:

If ΔBOK is similar to ΔPOS then the ratios of their corresponding sides are the same.

Given side lengths:

  • OP = 8 units
  • OB = 5 units
  • OS = 12 units

Therefore:

\sf \implies OP:OS = OB:OK

\sf \implies 8:5= 12:OK

\implies \sf (8)/(5)=(12)/(OK)

\implies \sf 8 \cdot OK = 12 \cdot 5

\implies \sf OK=(60)/(8)

\implies \sf OK=7.5

Therefore, the coordinates of K are (0, -7.5).

To find the scale factor, simply divide the corresponding side lengths of the larger triangle by the smaller triangle:

\implies \sf scale\:factor=(OP)/(OB)=(8)/(5)=1.6

The answer is 3x^4-13x^3-x^2-11x+6.

Solution:

Use algebraic identity: a^m* a^n=a^(m+n)

For example: x^2* x=x^(2+1)=x^3

Given expression (x^2-5x+2) and (3x^2+2x+3).

To multiply these equations.

(x^2-5x+2)*(3x^2+2x+3)

             =x^2(3x^2+2x+3)-5x(3x^2+2x+3)+2(3x^2+2x+3)

             =(3x^4+2x^3+3x^2)+(-15x^3-10x^2-15x)+(6x^2+4x+6)

             =3x^4+2x^3+3x^2-15x^3-10x^2-15x+6x^2+4x+6

Combine like terms together.

             =3x^4+(2x^3-15x^3)+(3x^2-10x^2+6x^2)-15x+4x+6

             =3x^4-13x^3-x^2-11x+6

(x^2-5x+2)*(3x^2+2x+3)=3x^4-13x^3-x^2-11x+6

Hence the answer is 3x^4-13x^3-x^2-11x+6.

Which data can best be represented by a line chart? A. rate of growth of a seedling over two weeks. B. distribution of total monthly expenditure. C. average annual yield of different processing plants in an industry.

Answers

The answer to the question is A which is rate of growth of seedling over two weeks. Line chart is a chart that shows information as series of data points that is called markers connected by a straight line. Hope my answer helps.

Answer:

A. rate of growth of a seedling over two weeks

Step-by-step explanation:

The answer is option A - rate of growth of a seedling over two weeks.

The data that can be best represented by a line chart is a linear relationship or time series data.

This type of data shows how something changes over a long or short period of time.

So, the best possible answer is  A. rate of growth of a seedling over two weeks.
