So, the easiest thing to do here is to add up the numbers of each option to find the number most similar to the solution of (-4/5)(3/5)(-6/7)(5/6) which is approximately equal to 0.34.
The product of expression A is -0.25
The product of expression B is 0.50
The product of expression C is 3
The product of expression D is -0.05625

So, first of all, we can rule out choices A and D because they are both negative, whereas 0.34 is not. Now, we just have B and C, and clearly, B is much closer to 0.34 than C is, so B is the correct answer. I hope this helps! :)

How Solve The D. E dy/dx=2x^5 y^3 - 4y/x

Pachacha [2.7K]

Dy/dx (2x⁵ y³ - 4y/x)

dy/dx (2y³ x⁵ - 4y/x)

dy/dx ( 2y³ x⁵ ) - dy/dx (4y/x)

= 2y³ 5x⁴ - (-4y × 1/x²)

=
10x⁶ y³ + 4y

Solve each system by graphing.

Kryger [21]

9514 1404 393

Answer:

(x, y) = (4, -4)

Step-by-step explanation:

A graphing calculator makes graphing very easy. The attachment shows the solution to be (x, y) = (4, -4).

The equations are in slope-intercept form, so it is convenient to start from the y-intercept and use the slope (rise/run) to find additional points on the line.

The first line can be drawn by staring at (0, -2) and moving down 1 grid unit for each 2 to the right.

The second line can be drawn by starting at (0, 2) and moving down 3 grid units for each 2 to the right.

The point of intersection of the lines, (4, -4), is the solution to the system of equations.

Express cos(27pi/8) as a trigonometric function of an angle in Quadrant I.

Kryger [21]

Answer:

The equivalent trigonometric ratio in Quadrant I is $-\cos (\frac{3\pi}{8})$

Step-by-step explanation:

The terminal side of $\frac{27\pi}{8}$ is in the 3rd quadrant.

The principal angle is $\frac{3\pi}{8}$

In other words, the terminal side of $\frac{27\pi}{8}$ makes an acute angle of $\frac{3\pi}{8}$ radian with the positive x-axis. Acute angles are in the first quadrant.

Since the cosine ratio is negative in the 3rd quadrant,

$\cos (\frac{27\pi}{8})=-\cos (\frac{3\pi}{8})$
