What is i^16 simplified

Crazy boy [7]

$\bf i^{16}\implies i^{4+4+4+4}\implies i^4\cdot i^4\cdot i^4\cdot i^4\implies 1\cdot 1\cdot 1\cdot 1$

and fairly sure you know how much that is.

A and B can do a work in 3 days but A working alone takes 4 days. In what time will B do it if he works alone?

zalisa [80]

Answer:

Let B have x days work:

A + B = 3 days

1/4 + 1/x = 1/3

1/3 - 1/4 = 1/x

1/12 = 1/x

x = 1 / (1/12)

x = 12

B takes 12 days

I do not know if this is right

A point moves along the curve y = √ x in such a way that the y-component of the position of the point is increasing at a rate of

Eduardwww [97]

Answer:

The value of x component changes at a rate of $\frac{dx}{dt}=4\sqrt{x}$ units per second

Step-by-step explanation:

We are given that $y=x^{\frac{1}{2}}$

Differentiating on both sides with respect to time we get

$\frac{dy}{dt}=\frac{d\sqrt{x}}{dt}\\\\\frac{dy}{dt}=\frac{1}{2}x^{\frac{-1}{2}}(\frac{dx}{dt})\\\\\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}$

It is given that $\frac{dy}{dt}=2units/sec$

Solving for $\frac{dx}{dt}$ we get

$\frac{dx}{dt}=\frac{dy}{dt}\times 2\sqrt{x}\\\\\frac{dx}{dt}=4\sqrt{x}$
