6. Given the implicit curve x^2-ln(x/y)=1 , Write the linear approximation () of the tangent line at (1,1) A) L(x)=-x-2 B) L(x)= -x+2 C) L(x)= -x-1 D) L(x)= -x+1

Answers

Answer:

B) L(x) = -x + 2

Step-by-step explanation:

To find the tangent at (1,1), we differentiate x² - ln(x/y) = 1 with resect to x.

So, x² - ln(x/y) = 1  

x² - (lnx - lny) = 1

x² - lnx + lny = 1

differentiating both sides with respect to x, we have

d{x² - lnx + lny]/dx = d1/dx

dx²/dx - dlnx/dx + dlny]/dx = d1/dx

2x - 1/x + 1/y(dy/dx) = 0

1/y(dy/dx) = 1/x - 2x

dy/dx = y(1/x - 2x)

dy/dx evaluated at (1,1) is

dy/dx = y(1/x - 2x)

= (1)(1/1 - 2(1))

= 1 - 2

= -1

This is the gradient of the tangent line.

To find the equation of the tangent line, we use (y - y')/(x - x') = m where y' = 1, x' = 1 and m = gradient of line = dy/dx = - 1

(y - y')/(x - x') = m

(y - y')/(x - x') = dy/dx

(y - 1)/(x - 1) = -1

cross-multiplying,

y - 1 = -1(x - 1)

expanding the bracket, we have

y - 1 = -x + 1

adding + 1 to both sides, we have

y -1 + 1 = -x + 1 + 1

y = -x + 2

So, L(x) = -x + 2

which shape has at least one 1 right angle

Answers

What do squares, rectangles, and right triangles have in common? They all contain at least one right angle!

What shape has at least one right angle?

rectangle

A rectangle is a four-sided shape where every angle is a right angle (90°). Also, the opposite sides are parallel and of equal length.

The shapes which contain at least one right angle from the given shapes are the first and third figures.

Given are four shapes.

It is required to find the shape with at least one right angle.

Now, right angles can be defined as the angle whose measure is exactly 90 degrees.

Anything measure of angle which is less than or greater than 90 degrees is not a right angle.

Consider the first figure.

There are 2 right angles marked in squared shape inside the shape in the right part.

So, the first figure contains the right angle.

In the second figure, all angle measures are 108 degrees. So none is a right angle.

In the third figure, all the angles are right angles since all are marked as squares.

In the last figure, the angle measures are only 73° and 107°. So, this is not right angles.

Hence, the options are first and third figures.

Answer: k = 19

because (6k+31)°  is the outer angle of the triangle

=> (6k+31)° = (3k - 12)° + (6k - 14)°

⇔ 6k + 31 = 9k - 26

⇔ 9k - 6k = 31 + 26

⇔ 3k = 57

⇔ k = 57/3 = 19

Find x if 75% of x = 27.​

Answers

36

that is the answer

Answer:

36%

Step-by-step explanation:

"Percent'' or ''%'' means ''out of 100'' or '' per 100'',

Therefore x% can be written as x/100.

So we can write and solve for x;

27/75= x/100

100 X 27/75 = 100 X x/100

2700/75 = 100 X x/100

36=x

27/75= 36/100= 36%
