Answer:

1471.15

A = πrl+πr²

l = \sqrt{r^2+h^2}

A = \pi r(r+\sqrt{h^2+r^2} ) = \pi  * 13 * (13 + \sqrt{19^2+13^2} )  ≈ 1471.15

Given right triangle JKL what is the value of cos(L)?
NemiM [27]
For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA. 
                          sin angle = opposite side / hypotenuse
                          cosine angle = adjacent side / hypotenuse
                          tangent angle = opposite side / adjacent side

If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
                                       cos (L) = j/k

A line of a slope of 8 passes through the point (-6,4). What is its equation in point slope form?
kotykmax [81]

Answer:

\huge\boxed{y-4=8(x+6)}

Step-by-step explanation:

The equation of a line in the point-slope form:

y-y_1=m(x-x_1)

m-slope\\\\(x_1;\ y_1)-point

We have:

m=8\\\\(-6;\ 4)\to x_1=-6;\ y_1=4

Substitute:

y-4=8(x-(-6))\\\\y-4=8(x+6)
