F(m)=m^4-6m^3+5m^2+10m-4 at m=4

Alexandra [31]

Answer:

F(m) = -12

Step-by-step explanation:

Given the function:

$F(m)=m^{4}-6m^{3}+5m^{2}+10m-4$

When m = 4, we substitute the variable 'm' for the number 4:

$F(m)=4^{4}-6(4)^{3}+5(4)^{2}+10(4)-4$

F(m) = 256 - 384 + 80 + 40 - 4

F(m) = -12

Derivative of y=(3x+5)^3

UkoKoshka [18]

$\\ \sf\longmapsto \dfrac{dy}{dt}$

$\\ \sf\longmapsto \dfrac{d}{dt}(3x+5)^3$

$\\ \sf\longmapsto \{3(3x+5)\}^2$

$\\ \sf\longmapsto (9x+15)^2$

$\\ \sf\longmapsto 9x^2+2(9x)(15)+(15)^2$

$\\ \sf\longmapsto 81x^2+270x+225$
