Answer:

20/3

Step-by-step explanation:

There are two ways to do this.

1) "invert and multiply" or "dot swap"

(10/9) ÷ (1/6) = (10/9) · (6/1)

The division is changed to multiplication (dot, ·) and the divisor fraction 1/6 is inverted (numerator and denominator are swapped).

The resulting product is ...

(10/9)×(6/1) = 60/9 = 20/3

__

2. Use a common denominator. The denominators 9 and 6 of the respective fractions have a least common multiple of 18. This means both fractions can be expressed using 18 as a denominator:

$\dfrac{\text{ }\dfrac{10}{9}\text{ }}{\dfrac{1}{6}}=\dfrac{\text{ }\dfrac{20}{18}\text{ }}{\dfrac{3}{18}}=\boxed{\dfrac{20}{3}}$

Once the fractions are expressed with a common denominator, the denominators can be ignored/removed/cancelled. They are equivalent to a factor of (a/a) = 1, where a=1/18.

Any point on the parabola can be labeled (x,y), as shown. What are the distances from the point (x,y) to the focus of the parabo

lapo4ka [179]

Answer:

Step-by-step explanation:

Standard form of the equation:

y = $-\frac{1}{4} (x+3)^2+3$

Directrix: y=4

Focus: (-3,2)

Points on the parabola (x,y):

(-5,2) (-3,3) (-1,2)

Distance from points to focus:

(-5,2) = (-3,2)

Answer choices: (x+3)^2+(y−3)^2, (x−2)2+(y+3)2, (x+3)2+(y−2)2

(-5+3)^2+(2-3)^2=5

(-5-2)^2+(2+3)^2=74

(-5+3)^2+(2-2)^2=4

(-1,2)

A TV that usually sells for $195.72 is on sale for 20% off. If sales tax on the TV is 9%, what is the price of the TV, including

Nuetrik [128]

The total cost of the TV is: $181.57

Work: 195.72 x 0.20 (20%) = 39.14

195.72 - 39.14 = 166.58 <-- Was for the discount now you have to do the tax.

Now Tax, 166.58 + 14.99 = 181.57

Hope this helps!

Differentiate x^2 e^x logx

zimovet [89]

Product rule:

$\dfrac{\mathrm d}{\mathrm dx}(x^2e^x\log x)$

$=\dfrac{\mathrm d(x^2)}{\mathrm dx}e^x\log x+x^2\dfrac{\mathrm d(e^x)}{\mathrm dx}\log x+x^2e^x\dfrac{\mathrm d(\log x)}{\mathrm dx}$

Power rule:

$\dfrac{\mathrm d(x^2)}{\mathrm dx}=2x$

The exponential function is its own derivative:

$\dfrac{\mathrm d(e^x)}{\mathrm dx}=e^x$

Assuming the base of $\log x$ is $e$ , its derivative is

$\dfrac{\mathrm d(\log x)}{\mathrm dx}=\dfrac1x$

But if you mean a logarithm of arbitrary base $b$ , we have

$y=\log_bx\implies x=b^y=e^{y\ln b}\implies1=e^{y\ln b}\ln b\dfrac{\mathrm dy}{\mathrm dx}$

$\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{e^{-y\ln b}}{\ln b}=\dfrac1{b^y\ln b}$

$\implies\dfrac{\mathrm d(\log_bx)}{\mathrm dx}=\dfrac1{x\ln b}$

So we end up with

$2xe^x\log x+x^2e^x\log x+\dfrac{x^2e^x}x$

$=xe^x(2\log x+x\log x+1)$
