Question

-0,5xc³,якщо x=-0,2,c=-1/2

Answer 1

Ответ:

-1/80

Пошаговое объяснение:

-0,5*(-0,2)*(-1/2)³=0,1*(-1/2)³=1/10*(-1/8)=-1/(10*8)=-1/80

Answer 2

To evaluate the expression -0.5xc³ when x = -0.2 and c = -1/2, we substitute the given values into the expression:

-0.5xc³ = -0.5 * (-0.2) * (-1/2)³

First, let's simplify the exponent term (-1/2)³:

(-1/2)³ = (-1/2) * (-1/2) * (-1/2) = -1/8

Now, substitute the values:

-0.5 * (-0.2) * (-1/2)³ = -0.5 * (-0.2) * (-1/8)

Next, multiply the numbers together:

-0.5 * (-0.2) * (-1/8) = 0.01 * (-1/8)

Finally, perform the multiplication:

0.01 * (-1/8) = -0.01/8 = -0.00125

Therefore, when x = -0.2 and c = -1/2, the value of -0.5xc³ is -0.00125.
