Answer:

The measure of angle CKJ is 44°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠LKJ=m∠LKC+m∠CKJ ----> by addition angle postulate

substitute the given values

$131\°=(x+96)\°+(x+53)\°$

solve for x

$131=2x+149$

$2x=131-149$

$x=-9$

<em>Find the measure of angle CKJ</em>

m∠CKJ=(x+53)°

substitute the value of x

m∠CKJ=(-9+53)=44°

56. How many tangent lines to the curve <img src="https://tex.z-dn.net/?f=y%3Dx%20%2F%28x%2B1%29" id="TexFormula1" title="y=x /(

PIT_PIT [208]

There are 2 tangent lines that pass through the point

$y=\frac{1}{(-1+\sqrt{3)^2} } (x-1)+2$

and

$y=\frac{1}{(-1-\sqrt{3)^2} } (x-1)+2$

Explanation:

Given:

$y=\frac{x}{x+1}$

The point-slope form of the equation of a line tells us that the form of the tangent lines must be:

$y=m(x-1)+2$ $[1]$

For the lines to be tangent to the curve, we must substitute the first derivative of the curve for $m$ :

$\frac{dy}{dx} =\frac{d(x)}{dx}(x+1)-x^\frac{d(x+1)}{dx} \\ \\$

$\frac{dy}{dx} =\frac{x+1-x}{(x+1)^2}$

$\frac{dy}{dx}= \frac{1}{(x+1)^2}$

$m=\frac{1}{(x+1)^2}$ $[2]$

Substitute equation [2] into equation [1]:

$y=\frac{x-1}{(x+1)^2}+2$ $[1.1]$

Because the line must touch the curve, we may substitute $y=\frac{x}{x+1}:$

$\frac{x}{x+1}=\frac{x-1}{(x+1)^2}+2$

Solve for x:

$x(x+1)=(x-1)+2(x+1)^2$

$x^2+x=x-1+2x^2+4x+2$

$x^2+4x+1$

$x\frac{-4±\sqrt{4^2-4(1)(1)} }{2(1)}$

$x=-2$ ± $\sqrt{3}$

$x=-2$ ± $\sqrt{3}$ <em> </em> $and$ $x=-2-\sqrt{3}$

There are 2 tangent lines.

$y=\frac{1}{(-1+\sqrt{3)^2} } (x-1)+2$

and

$y=\frac{1}{(-1-\sqrt{3)^2} } (x-1)+2$

An airline claims that 90% of the time, its planes are on schedule. If three flights are selected at random, what is the probabi

serg [7]

1. Check the tree diagram in the picture attached.

2. The blue segment represents "on time"
The red segment represents "not on time"

3. blue - blue - red represents the case 1st on time, 2nd on time, 3rd not on time.

the combined probability is 90/100*90/100*10/100=9/10*9/10*1/10=99/1000=0.099

4. Remark with a tree diagram we can tell anything asked about the probability of an experiment.

The Animal World Safari Park is a rectangular piece of land with an area of 323 square miles. The length of the park is 17 miles

Charra [1.4K]

The area of a rectangle is A = L * W. We have the area as 323 and the length as 17. Filling in our formula for area then, 323 = 17W. Divide both sides by 17 to solve for the width. W = 19

Please awnser questions, no links, no I dont know

balandron [24]

Answer: C

Step-by-step explanation:

The equation is 3x = 6, that represents 3 x ? = 6, babe. 3 x 2 = 6, so that means C must be the answer. If it was D, it would be 0.2 I think, and if it was B, it would’ve been -2. If it was A, it would’ve been 0. Bye-bye toots~
