A2. Find y' and y" for y^2 = x^2 + sinxy

kumpel [21]

Answer:

y' = (2x + y cosxy)/(2y + x cosxy)

Step-by-step explanation:

Using implicit differentiation:

y^2 = x^2 + sin xy

2y y' = 2x + cos xy * (xy' + y)

2y y' = 2x + xy' cos xy + y cos xy

2y y' - xy' cosxy = 2x + ycos xy

y' = (2x + y cosxy)/(2y - x cosxy)

Someone tell me how to do this

nirvana33 [79]

So you first make 1 7/9 into 16/9
then you do 16/9 - 4/9 which equals to 12/9 then you simplify and get 4/3 then simplify again into 1 1/3

Slope intercepts No links, Will mark BRAINLIEST

Sergeeva-Olga [200]

Answer:

Lines are perpendicular to each other .

Step-by-step explanation:

Standard equation of line is : y = mx + c, Where m represents the slope

Given Equations :

$y = -5x + 1\\\\Slope , m_1 = -5$

$y = \frac{1}{5}x +1\\\\Slope, m_2 = \frac{1}{5}$

Two lines are parallel if the slope of the lines are same.

Two line are perpendicular if the product of the slope = - 1

Clearly slopes are not equal , therefore the lines are not parallel.

product of the slope is - 1, therefore the lines are perpendicular.

$m_1 \times m_2 = -5 \times \frac{1}{5} = - 1$

You are running a fuel economy study. One of the cars you find is blue. It can travel 28 2/5 miles on 1 1/4 gallons of gasoline.

Harrizon [31]

Answer:

Blue car: 30.5 / 1.25 =24.4 miles per gallon

Red car: 25.6/0.80 =32 miles per gallon

You can easily see that the Red car travel farther on 1 gallon of gasoline.
