How to find the values of X

Mathematics
1 answer:
Aloiza [94]4 years ago
5 0

The cubic equation y=x^3-3x^2+1 can be differentiated to obtain a formula for the slope of any tangent line to the curve. 

Thid derivative is dy/dx = 3x^2-6x.

Since we're interested in finding x values at which the tangent line is horiz., we set this deriv. = to 0.  Factoring, 3x(x-2)=0.  Thus, x=0 and x=2.

You could verify this by graphing the original function on a graphing calculator.  Determine from your graph the x-values at which the tangent lines to the graph appear to be horiz.

The height of the carton of oatmoatmeal is 9 inches.

Step-by-step explanation:

Radius = 4 inches

Area of cardboard used = 276 square inches

Required surface area = π(r x r) + 2πrh

276 = π(4 x 4) + 2π(4 x h)

276 = 16π + 8π(h)

276 = 50.24 + 25.12(h)

276 - 50.24 = 25.12(h)

225.76 = 25.12(h)

(225.76) /(25.12) = h

h = 9 inches

The height of the carton of oatmoatmeal is 9 inches.

A pergunta não está bem formatada. No entanto, pelo que parece óbvio

Responda:

3 horas

Explicação passo a passo:

Fração de hora gasta por sessão = 3/4 horas por sessão

Se o exercício for feito apenas aos domingos

Número de domingos por mês = 4

Portanto, número de sessões = 4

Fração de horas por sessão * Número de sessões

3/4 * 4 = 3 horas

Portanto, 3 horas são dedicadas ao exercício por mês
