Question

Найди значение отрезка AS , который является средним пропорциональным отрезков DF= 12 см и CV=48 см.

Answer 1

Ответ:

AS = 24 см

Пошаговое объяснение:

Средним пропорциональным двух отрезков называется величина, равная корню квадратному из произведения длин этих отрезков:

AS = √DF*CV = √12*48 = √576 = 24 см

12 : 24 = 24 : 48

1 : 2 = 1 : 2

Answer 2

Finding the Mean Proportional

To find the value of the segment AS, which is the mean proportional between the segments DF and CV, we can use the following formula:

AS = √(DF * CV)

Where: - AS is the mean proportional - DF = 12 cm - CV = 48 cm

Calculation

Using the given values: - DF = 12 cm - CV = 48 cm

We can calculate the mean proportional AS using the formula:

AS = √(12 * 48)

Result

AS = √(576) = 24 cm

So, the value of the segment AS, which is the mean proportional between the segments DF and CV, is 24 cm.
