Rewrite the expression as a single logarithm and simplify the result.<br> ln lcosxl +lnltanxl

NNADVOKAT [17]

Recall your logarithms rules

$\bf ln|cos(x)|+ln|tan(x)|\\\\
-----------------------------\\\\
log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)\qquad thus\\\\
-----------------------------\\\\
ln|cos(x)tan(x)|\implies ln\left| cos(x)\cdot \cfrac{sin(x)}{cos(x)} \right|\implies 
ln|sin(x)|$

Surface area of hemisphere with diameter of 18

saul85 [17]

Answer:

In terms of pi: 243 $\pi$

in decimal form: 763.407

Step-by-step explanation:

to find surface area of a hemisphere the formula is,

$3\pi r^{2}$

diameter (d) = 18

radius = d / 2 = 18 / 2

radius = 9

$3\pi (9)^{2} \\3\pi (81)\\243\pi \\OR\\763.407$

the point 3,2 lies on a circle.what is the exact length of the radius of this circle if the center is located at (-1,-4)

Crazy boy [7]

You can use the distance formula to solve this.

Distance Formula:
$d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}$

I am going to use point (3,2) as point 1 and (-1,-4) as point 2
Insert the points into the formula
$d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}$
$d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}$
Solve:
$d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}$
$d = \sqrt{(-4)^2 + (-6)^2}$
$d = \sqrt{16 + 36}$
$d = \sqrt{52}$
$d = \sqrt{52} = \sqrt{4}\sqrt{13}$
$d = \sqrt{52} = 2 \sqrt{13}$
$d = 2 \sqrt{13}$
$radius = 2 \sqrt{13} = 7.2111$
