What is f(x) - g(x)?

Gala2k [10]

$f(x)=9x^3+2x^2-5x+4\\\\g(x)=5x^3-7x+4\\\\f(x)-g(x)=(9x^3+2x^2-5x+4)-(5x^3-7x+4)\\\\=9x^3+2x^2-5x+4-5x^3+7x-4=9x^3-5x^3+2x^2-5x+7x+4-4\\\\=\boxed{4x^3+2x^2+2x}$

Solve for the missing part of the proportion. 13/27 = ?/324

Studentka2010 [4]

13/27 = ?/324

Since 324 divided by 27 is 12, you multiply 13 by 12 to get '?'

13*12= 156

13/27 = 156/324

? = 156

A particle moves along a horizontal line. Its position function is s(t) for t is greater than or equal to 0. For each problem, f

OleMash [197]

Answer:

1) Velocity

$v(t) = -4\cdot t^{3}+36\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+72\cdot t$

2) Velocity

$v(t) = -4\cdot t^{3}+24\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+48\cdot t$

Step-by-step explanation:

From Physics we remember that velocity ( $v(t)$ ) and acceleration ( $a(t)$ ) are the first and second derivatives of the function position in time. That is:

1) Let $s(t) = -t^{4}+12\cdot t^{3}$ , where $t \ge 0$ . The functions velocity and aceleration are, respectively:

Velocity

$v(t) = -4\cdot t^{3}+36\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+72\cdot t$

2) Let $s(t) = -t^{4}+8\cdot t^{3}$ , where $t\ge 0$ . The functions velocity and acceleration are, respectively:

Velocity

$v(t) = -4\cdot t^{3}+24\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+48\cdot t$
