Answer:

Step-by-step explanation:

since we were handily told the formula for the volume of a hemisphere in your last problem , just use that, 2/3 $\pi$ $r^{3}$

2/3 $\pi$ $15^{3}$ = got it?

What are the steps to solving this limit?

patriot [66]

Answer:

lim(x---->0) = -5

Step-by-step explanation:

first: sin(x-π/2)= -cosx

so the equation will be :

lim(x---->0) = [-6cos(ax)-1}/cosx

solve :

lim(x---->0) = [-(6cos(a(0))-1}/cos(0)

cos0=1

lim(x---->0)=(-(6(1)-1)/1

lim(x---->0)=-6+1/1

lim(x---->0)=-5

Find the values of x, y, and z. The diagram is not to scale.

Kruka [31]

we know that

The sum of the internal angles in the triangle must be $180$ degrees

see the attached figure with letters to better understand the problem

Step $1$

<u>Find the measure of the angle x</u>

In the triangle ABC

$63\°+36\°+x\°=180\°$

solve for x

$99\°+x\°=180\°$

$x\°=180\°-99\°$

$x=81\°$

therefore

<u>the answer Part a) is</u>

the measure of angle x is $81\°$

Step $2$

<u>Find the measure of the angle z</u>

we know that

$x+z=180\°$ --------> by supplementary angles

substitute the value of x

$81\°+z=180\°$

$z=180\°-81\°$

$z=99\°$

therefore

<u>the answer Part b) is</u>

the measure of angle z is $99\°$

Step $3$

<u>Find the measure of the angle y</u>

In the triangle ACD

$13\°+z\°+y\°=180\°$

solve for y

$13\°+99\°+y\°=180\°$

$112\°+y\°=180\°$

$y\°=180\°-112\°$

$y\°=68\°$

therefore

<u>the answer Part c) is</u>

the measure of angle y is $68\°$
