how do i solve this?

Answer:

y = -3π/2 x + π

Step-by-step explanation:

sin(xy) = ½

The slope of the tangent line is dy/dx.  Take the derivative of both sides with respect to x.  You'll need to use chain rule and product rule.

cos(xy) (x dy/dx + y) = 0

x dy/dx + y = 0

x dy/dx = -y

dy/dx = -y/x

At x = ⅓ and y = π/2:

dy/dx = -(π/2) / ⅓

dy/dx = -3π/2

Using point-slope form of a line:

y − π/2 = -3π/2 (x − ⅓)

Simplifying to slope-intercept form:

y − π/2 = -3π/2 x + π/2

y = -3π/2 x + π

Answer:

27/6, 4 3/6, or simplified version 4 1/2

Step-by-step explanation:

Always convert the mixed numbers into an improper fraction before you solve, this makes it easier to solve.

2 4/6 = 16/6

1 5/6 = 11/6

3 4/6 = 22/6

Now we solve. Remember, you do NOT add the denominator, leave it as 6 not 12. You only add the numerator.

16/6 + 11/6 = 27/6, 4 3/6 or simplified as 4 1/2

22/6 + 5/6 = The same as above.

Answer:

The answer is all of them except the last one so... A,B,C,D,E.

Step-by-step explanation:

To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root. Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0.

Answer:Each person should get 7.5 milliliters  or seven and a half perfume.

Step-by-step explanation:

15/2=7.5

Each person should get 7.5 milliliters or seven and a half perfume.

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in maths and science.

Thus, unit price of something is price of 1 thing.

Suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

WE know that 2 people are evenly sharing 15 milliliters of perfume.

So, one person will share;

15/2

=7.5

Therefore, Each person should get 7.5 milliliters or seven and a half perfume.

Answer:

A = 19.47

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hypotenuse

sin A = 2/6

Take the inverse sin of each side

sin ^-1 ( sin A) = sin ^-1 (2/6)

A =19.47122063

To the nearest hundredth

A = 19.47

Answer:

  c.  y = 3.25^x

Step-by-step explanation:

At x=1, the value of y is slightly more than 3, so the base must be more than 3. The appropriate choice is ...

Answer: -18h^2 + 85h - 18

Step-by-step explanation:

(-2h+9)(9h-2)

Open brackets

(-2h x 9h) + (-2h x -2) + (9 x 9h) + (9 x -2)

-18h^2 + 4h + 81h - 18

Add like terms 4h + 81h

-18h^2 + 85h - 18

The question is incomplete. Here is the complete question.

A differential equation is given along with the field of problem area which it arises. Classify it as an ordinary differential equation (ODE) or a partial different equation (PDE), give the order, and indicate the independent and dependent variables. If the equation is an ordinary differential equation, indicate whether the equation is linear or nonlinear.

[tex]x\frac{d^{2}y }{dx^{2} } + \frac{dy}{dx} + xy = 0[/tex] (aerodynamics, stress analysis)

Answer and Step-by-step explanation: The differential equation described above is an Ordinary Differential Equation, because it has a definite set of variables: x and y.

It is of Second Order, since the highest derivative is of order 2: [tex]\frac{d^{2}y }{dx^{2} }[/tex]

The differential equation is written as derivative of a function y in terms of x, which means: Independent Variable is X and Dependent Variable is Y.

As it is an ODE, the equation is Nonlinear, because y'' or [tex]\frac{d^{2}y }{dx^{2} }[/tex] is multiplied by a variable.

Answer

d. the correlation between length of essays and SAT score is significant.

Step-by-step explanation:

According to the case information, we know that the slope of the regression equation is -0.88 to 1.34, so our hypothesis is that the slope coefficient is 0, we deduce that taking into account the confidence interval the value is included by therefore the correct answer is D, which allows us to affirm that the correlation between the duration of the tests and the SAT score is significant

Answer:

x = -3 and y = 0

Step-by-step explanation:

It would be more direct to apply elimination in this problem, rather than substitution:

  2x + 6y = -6       ⇒      2x + 6y = -6       ⇒      10x = - 30

+ 2(4x - 3y = -12)        +  8x - 6y = -24

Now let us solve for x through simply algebra:

10x = -30,

  x = -3

Substitute this value of x into the first equation to get the value of y:

2( -3 ) + 6y = -6,

-6 + 6y = -6,

  6y = 0,

    y = 0

-3 and 0
