Answer:

y = 0.9

Step-by-step explanation:

Given : $Cos y = \frac{8}{13}$ .

To find : Find the value of y. Round your answer to the nearest tenth.

Solution : We have given

$Cos y = \frac{8}{13}$ .

On taking the inverse of cos both sides .

y = $Cos^{-1}(\frac{8}{13})$

y = 0.90792

Up to nearest tenth 0 .9

y = 0.9

Therefore, y = 0.9

Find the limit of the function by using direct substitution as X approaches one lim(x^2-8x -2)

Leno4ka [110]

Answer:

$lim_{x \to 1} x^2 -8x -2 =-9$

Step-by-step explanation:

For this case we want to find the following limit:

$lim_{x \to 1} x^2 -8x -2$

And we can find the limit distirbuting into each term like this:

$\lim_{x \to 1} x^2 -8 lim_{x \to 1} x -lim_{x \to 1} 2$

And replacing we got:

$1^2 - 8*1 -2 = 1-8-2 = -9$

So then the final answer for this case is:

$lim_{x \to 1} x^2 -8x -2 =-9$
