Brums [2.3K]
We know, Volume of a Sphere = 4/3 πr³
v = 4/3 * 3.14 * 6³
v = 4.186 * 216
v = 904.32 cm³

In short, Your Answer would be Option D

Hope this helps!

Write the expression as a single natural logarithm.3 ln x – 5 ln c
shtirl [24]
The rules are ...
\Longrightarrow \ln(\frac{a}{b})=\ln(a)-\ln(b)
\Longrightarrow \ln(a^{b})=b\ln(a)

Your expression makes use of both these rules.
3\ln(x)-5\ln(c)=\ln(x^{3})-\ln(c^{5})=\ln \left( \dfrac{x^{3}}{c^{5}} \right)

Your single logarithm is ...
  \ln \left( \dfrac{x^{3}}{c^{5}} \right)

In the kite , AK=9 , JK=15 , and AM=16 .
Veronika [31]

Answer:

The Length of JM is 20.

Step-by-step explanation:

Given,

JKLM is a kite in which JL and KM are the diagonals that intersect at point A.

Length of AK = 9    

Length of JK = 15  

Length of AM = 16

Solution,

Since JKLM is a kite. And JL and KM are the diagonals.

And we know that the diagonals of a kite perpendicularly bisects each other.

So, JL ⊥ KM.

Therefore ΔJAK is aright angled triangle.

Now according to Pythagoras Theorem which states that;

"The square of the hypotenuse is equal to the sum of the square of base and square of perpendicular".

JK^2=KA^2+AJ^2

On putting the values, we get;

(15)^2=9^2+AJ^2\\\\225=81+AJ^2\\\\AJ^2=225-81=144

On taking square root onboth side, we get;

\sqrt{AJ^2} =\sqrt{144}\\\\AJ=12

Again By Pythagoras Theorem,

AJ^2+AM^2=JM^2

On putting the values, we get;

JM^2=(12)^2+(16)^2\\\\JM^2=144+256=400

On taking square root onboth side, we get;

\sqrt {JM^2}=\sqrt{400}\\\\JM=20

Hence The Length of JM is 20.

Please Help ASAP!!!<br> Question in image below.
Luda [366]

Answer:

You know that XZ is 15 and the whole perimeter of the triangle is 50. WZ is going to be the same length as WX due to the lines saying that they are equal.

Your first step is to take 50-15=35, we did this because we already know the length of one side and can take that off from the whole.

The next step is to divide 35 by 2, because both sides are going to be the same length.

35/2=17.5

You final answer would be 17.5

Hope this helps ;)
