142/80 into mixed number

1 answer:

8 0

80 goes into 142 once, so one is our whole number. there are still 62 / 80 left, so we reduce this fraction. The answer is 1 $\frac{31}{40}$

Find the derivative of the function. y = sin−1(6x + 1)

liraira [26]

If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:

$y=\sin^{-1}(6x+1)\implies\sin y=6x+1$

(true for <em>y</em> between -π/2 and π/2)

Now take the derivative of both sides and solve for it:

$\cos y\dfrac{\mathrm dy}{\mathrm dx}=6$

$\dfrac{\mathrm dy}{\mathrm dx}=6\sec y$

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\cos\left(\sin^{-1}(6x+1)\right)}$

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\sqrt{1-(6x+1)^2}}$

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.

wolverine [178]

Answer:

$\lambda=10^{-10}\ m$

Step-by-step explanation:

Given that,

The frequency of x-rays, $f=3\times 10^{18}\ Hz$

We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :

$v=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^{8}}{3\times 10^{18}}\\\\=10^{-10}\ m$

So, the wavelength for x-rays is $10^{-10}\ m$ .

I DESPERATELY NEED HELP PLZ ANSWER THESE QUESTIONS I AM TIMED AND DON"T HAVE MUCH TIME LEFT

Marina CMI [18]

Answer:

Ok I will help you answer the first one the rest yourself?

Step-by-step explanation:

So the question is

6(r-s+t)

we have to time each number by 6

6r-6s+6t

That's how we can simply so the answer is 6r-6s+t

Same thing goes with the others
