Simplify. Rationalize the denominator. 3/9-√2

Gwar [14]

$\frac{3}{9-\sqrt{2} } * \frac{9+\sqrt{2}}{9+\sqrt{2}}$

$\frac{27 + 3\sqrt{2} }{9^{2} - (\sqrt{2})^{2} }$

$\frac{27 + 3 \sqrt{2} }{81 - 2}$

$\frac{27 + 3\sqrt{2} }{79}$

If 80% of M is equal to 50% of N and N≠0, what is N M equal to?

asambeis [7]

Answer:

0.625N

0.50N

0.80M = 0.50N, so M = ------------

0.80

and so:

0.50N

N*M = N*------------ = (5/8)N, or 0.625N

0.80

you go to a grocery store and buy a $2.50 bag of sugar and a sandwich for $1.75. The sales tax for your state is 7%. What is the

Rashid [163]

Answer: My guess is $4.55

Step-by-step explanation:

2.50 + 1.75 = 4.25 (This is the total of everything you bought)

4.25 x 0.07= 0.2975 (0.2975 is 7% of 4.25 but because this is money I will round it to 0.30)

(0.30 is the tax so now add it to the original amount)

$4.25 + $0.30 = $4.55

Help please i don’t know how to do it

Norma-Jean [14]

Answer:

Step-by-step explanation:

$\frac{dy}{dx}=x^{2}(y-1)\\\frac{1}{y-1} \text{ } dy=x^{2} \text{ } dx\\\int \frac{1}{y-1} \text{ } dy=\int x^{2} \text{ } dx\\\ln|y-1|=\frac{x^{3}}{3}+C\\$

From the initial condition,

$\ln|3-1|=\frac{0^{3}}{3}+C\\\ln 2=C$

So we have that $\ln |y-1|=\frac{x^{3}}{3}+\ln 2\\e^{\frac{x^{3}}{3}+\ln 2}=y-1\\2e^{\frac{x^{3}}{3}}=y-1\\y=2e^{\frac{x^{3}}{3}}+1$
