Find two numbers if their ratio is 9:11 and their difference is 6. Not 27 and 33

meriva

Answer:

Sets of numbers are ( 27,33) and (-27, -33)

Explanation;

Let the numbers be a and b.

We have their ratio is 9:11

$\frac{a}{b} =\frac{9}{11} \\ \\11a=9b$

Their difference is 6

$\left | a- \right b|=7$

( a - b) = 6 or (b - a ) = 6

11a - 11 b = 66 or 11b - 11a = 66

9b - 11 b = 66 or 11b -9b = 66

-2b = 66 or 2b = 66

b = -33 or b = 33

if b = -33, a = -33 + 6 = -27

if b = 33, a = 33-6 =27

So, the sets of numbers are ( 27,33) and (-27, -33)

It is given that m=3x+1 and y= (5/1+m^2).<br>Find dy/dx in terms of x.<br>

DiKsa [7]

Answer:

${ \underline{ \bf{ \frac{dy}{dx} = - \frac{30m}{ {(1 + {m}^{2}) }^{2} } }}}$

Step-by-step explanation:

${ \bf{m = 3x + 1}} \\ { \sf{ \frac{dm}{dx} = 3 }} \\ \\ { \bf{y = \frac{5}{1 + {m}^{2} } }} \\ \\ { \tt{ \frac{dy}{dm} = \frac{ - 10m}{ {(1 + {m}^{2} )}^{2} } }}$

Using chain rule:

${ \boxed{ \bf{ \frac{dy}{dx} = \frac{dy}{dm}. \frac{dm}{dx} }}}$

${ \sf{ \frac{dy}{dx} = - \frac{10m}{ {(1 + {m}^{2}) }^{2} } \times 3}} \\ \\ { \sf{ \frac{dy}{dx} = - \frac{30m}{ {(1 + {m}^{2}) }^{2} } }}$

${ \underline{ \sf{ \blue{christ \:† \: alone }}}}$

An organization will give a prize to a local artist. The artist will be randomly chosen from among 10 painters, 3 sculptors, and

Fofino [41]

The probability is 8/18 or 44%.

Since there are 3 sculptors and 5 photographers, and the question is asking for either a sculptor or photographer, you add them together. There are a total of 18 artists, and the probability is the chance of a certain thing happening over the total amount of things that can happen (i.e. a coin landing on heads is 50%).

The answer would be 8/18.
