The scale factor from Figure A to Figure B is 4

<h3>How to determine the scale factor from Figure A to Figure B?</h3>

From the question, we have the following statement:

Figure B is a scaled copy of Figure A.

The corresponding side lengths of figure A and figure B are:

Figure A = 10

Figure B = 40

The scale factor from Figure A to Figure B is then calculated as:

Scale factor = Figure B/Figure A

Substitute the known values in the above equation

Scale factor = 40/10

Evaluate the quotient

Scale factor = 4

Hence, the scale factor from Figure A to Figure B is 4

A plant grows at a constant rate . daniel records the height of the plant each week . the unit reat is meausred in inches per we
KATRIN_1 [288]

By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.

<h3>How to find a constant of proportionality in direct proportional equation</h3>

Let x and y the number of weeks and the height of the plant, respectively. Given the consideration of <em>direct</em> proportionality, the height of the plant inasmuch as the number of weeks increases. Then, the constant of proportionality (in inches per week) is found by dividing the height of the plant by the number of the respective week:

k = 18 inches /6 weeks = 15 inches /5 weeks = 12 inches/4 weeks = 3 inches/week

By the consideration of <em>direct</em> proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
