Solve. 3^x+1 = 9^ 5x a. x=3 b. x = 1/3 c. x=9 d. x= 1/9

jasenka [17]

Answer:

x = 1/9

Step-by-step explanation:

3^ (x+1) = 9 ^ (5x)

Replace 9 with 3^2

3^ (x+1) = 3^2 ^ (5x)

We know that a^b^c = a ^(b*c)

3^ (x+1) = 3^(2 * (5x))

3^ (x+1) = 3^(10x)

The bases are the same so the exponents are the same

x+1 = 10x

Subtract x from each side

x+1-x = 10x-x

1 = 9x

Divide each side by 9

1/9 = 9x/9

1/9 =x

You = her*1.1

her = you/1.1 = you*0.9090...

her = you - you*(1 - 0.9090...) = you - you*0.0909...

--> 9.09% younger

x = 9.09

Evaluate the intergal F•dr where F (x,y,z)=xyi+yzj+zxk and c is the twisted cubic given by x=t, y=t^2 ,z=t^3, 0<=t=<1

iogann1982 [59]

The integral can be evaluated by substituting everything you know:

$\displaystyle\int_C\mathbf F\cdot\mathrm d\mathbf r=\int_C\mathbf F(x(t),y(t),z(t))\cdot\dfrac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt$

$=\displaystyle\int_0^1(t^3\,\mathbf i+t^5\,\mathbf j+t^4\,\mathbf k)\cdot(\mathbf i+2t\,\mathbf j+3t^2\,\mathbf k)\,\mathrm dt$

$=\displaystyle\int_0^1(t^3+5t^6)\,\mathrm dt$

$=\dfrac{t^4}4+\dfrac{5t^7}7\bigg|_0^1=\dfrac14+\dfrac57=\boxed{\dfrac{27}{28}}$
