Finding Derivatives Implicity In Exercise, find dy/dx implicity. ln xy + 5x = 30

Sphinxa [80]

Answer:

dy/dx = -5y - y/x

Step-by-step explanation:

In xy + 5x = 30

Differentiating xy implicitly

y + xdy/dx

Assuming u = xy

In xy = In u

Differentiating In u = 1/u = 1/xy

Differentiating 5x = 5 and differentiating a constant (30) = 0

1/xy(y + xdy/dx) + 5 = 0

(y + xdy/dx)/xy = -5

(y + xdy/dx) = -5xy

xdy/dx = -5xy - y

dy/dx = = (-5xy - y)/x

dy/dx = -5y - y/x

Triangle ABC has a perimeter of 22cm

Bumek [7]

Answer:

triangle ABC is "not" a right-angled triangle

Step-by-step explanation:

AB=8cm

BC=5cm

perimeter = 22cm

CA = 22 - 8 - 5 = 9

8² + 5² = 89

9² = 81

AB² + BC² ≠ CA²

Mozart's Music Store rents trombones for $34 a month. Bach's Music Store rents trombones for $30 per month plus a yearly fee of

jeka94

Answer:

Step-by-step explanation:

Let $M(x)$ be the cost of renting from Mozart's Music Store for $x$ years, and $B(x)$ be the cost of renting from Bach's Music Store for $x$ years.

From the problem statement, we can come up with the following equations:

$M(x) = 34(12x)$

$B(x) = 30(12x) + 48x$

Plugging in $x = 9$ for each equation, we can get the answer:

$M(9) = 34(12 * 9)$

$M(9) = 34(108)$

$M(9) = 3672$

$B(9) = 30(12 * 9) + 48(9)$

$B(9) = 30(108) + 432$

$B(9) = 3240 + 432$

$B(9) = 3672$

From this, we can see that the value is equal for both stores.

What is the value of (10 x 0.5) squared + 4 cubed?

kotegsom [21]

First set up the equation:
$(10*0.5)^{2}$ + $4^{3}$

Now solve the ones in the parenthesis:
$5^{2}$ + $4^{3}$

Then do the exponents:
25+64

The answer will be: 89

Hope this helps!
