Answer:

Step-by-step explanation:

The y intercept is is -3 so that eliminates 2 options. Next the king goes up to the top right so it’s a positive slope. So that leaves only one option. The slope goes up one and to the side two. So it’s 1/2

I need help plz 8th math

Lemur [1.5K]

Answer:

56°

Step-by-step explanation:

hii!

to solve this, we need to know that the angles of a triangle all add up to 180 degrees.

we are going to make an x equation here.

2x+3x+40=180

5x+40=180

-40 -40

5x=140

/5 /5

x=28

angle a is 2x, so the answer would be 28*2 which is 56°

hope this helped out :)

Lim x->pi/3 ((2cosx-1)/(tan^2x-3))

beks73 [17]

You can check that the limit comes in an undefined form:

$\displaystyle \lim_{x\to\frac{\pi}{3}} \frac{2\cos(x)-1}{\tan^2(x)-3}=\dfrac{0}{0}$

In these cases, we can use de l'Hospital rule, and evaluate the limit of the ratio of the derivatives. We have:

$\dfrac{\text{d}}{\text{d}x}2\cos(x)-1 = -2\sin(x)$

and

$\dfrac{\text{d}}{\text{d}x}\tan^2(x)-3 = 2\dfrac{\tan(x)}{\cos^2(x)}=\dfrac{2\sin(x)}{\cos^3(x)}$

So, we have

$\displaystyle \lim_{x\to\frac{\pi}{3}} \frac{2\cos(x)-1}{\tan^2(x)-3}=\lim_{x\to\frac{\pi}{3}} \dfrac{-2\sin(x)}{\frac{2\sin(x)}{\cos^3(x)}}=\lim_{x\to\frac{\pi}{3}}-\cos^3(x)=-\cos^3\left(\dfrac{\pi}{3}\right)$
