Answer 1

Ответ:

Объяснение:0,02ху^2

0,02*15*(-2)^2= 0,02*15*4=1,2

Answer 2

To evaluate the expression 0.02xy^2 when x = 15 and y = -2, we can substitute the given values into the expression and perform the calculation.

Substituting x = 15 and y = -2 into the expression 0.02xy^2, we have:

0.02 * 15 * (-2)^2

First, let's calculate (-2)^2:

(-2)^2 = 4

Now, substitute the calculated value into the expression:

0.02 * 15 * 4

Next, multiply 0.02 and 15:

0.02 * 15 = 0.3

Now, substitute the result back into the expression:

0.3 * 4

Finally, multiply 0.3 and 4:

0.3 * 4 = 1.2

Therefore, when x = 15 and y = -2, the value of the expression 0.02xy^2 is 1.2.
