If (x 2y)dy/dx=2x-y what is the value of.
Radda [10]

The second differential of the function is 3/7

Given the differential function (x +2y)=\frac{dy}{dx} (2x-y)

Differentiate both sides with respect to x implicitly

(x +2y)=\frac{dy}{dx} (2x-y)

1+2y'=y"(2x-y)+y'(2-y')  \\y''=\frac{1+2y'}{(2x-y)+y'(2-y') }

Get the first derivative at the point (3, 0)

y'=\frac{2x-y}{x+2y} \\y'=\frac{2(3)-0}{0+2(3)}\\y'=\frac{6}{6} \\y'=1

Substitute into the second derivative to have:

y''=\frac{1+2y'}{(2x-y)+y'(2-y') }\\y''=\frac{1+2(1)}{(2(3)-0)+(1)(2-(1)) }\\y''=\frac{3}{6+1} \\y''=\frac{3}{7}

Hence the second differential of the function is 3/7

2. Find the correlation coefficient AND best fit line, of the following data use the linear model
shtirl [24]

Ans? u9999y

Step-by-step explanation:

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Which is the value of x?<br><br> a. x=3<br> b. x=6.5<br> c. x=8.5<br> d. x=14
Elodia [21]

Answer:

x = 14

Step-by-step explanation:

The angles form a straight line which makes them add to 180 degrees

4x+ 8x+12 =180

Combine like terms

12x+12 =180

Subtract 12 from each side

12x+12-12 = 180-12

12x=168

Divide each side by 12

12x/12 =168/12

x =14
