Answer:

The correct option is 1.

Step-by-step explanation:

Given information: AD = 25, CD = 5, DB = 1 and CD⊥AB.

According to the Pythagoras theorem,

hypotenuse^2=base^2+perpendicular^2

In triangle BCD,

CB^2=DB^2+CD^2

CB^2=1^2+5^2

CB^2=26

Taking square root both sides.

CB=\sqrt{26}

In a right angled triangle,

\sin\theta=\frac{opposite}{hypotenuse}

\sin B=\frac{CD}{CB}

\sin B=\frac{5}{\sqrt{26}}

\sin B=0.980580675691

\sin B\approx 0.9806

Therefore the correct option is 1.

A sphere with radius 16 m is cut by a plane that is 9 m below its center. what is the best approximation of the area of the circ
alexdok [17]
The complete question in the attached figure

we know that
the equation of a sphere is
(x-h)²+(y-k)²+(z-l)²=r²

<span>let's assume that the center of the sphere is at the origin
</span>so
(h,k,l)-------> (0,0,0)
for r=16 m
(x-h)²+(y-k)²+(z-l)²=r²-------->  (x)²+(y)²+(z)²=16²

for z=9 m
(x)²+(y)²+(9)²=16²--------> (x)²+(y)²=256-81--------> (x)²+(y)²=175
the radius of the circle is r=√175 m
so the area of the circle A=pi*r²-----> A=pi*175-----> A=549.5 m²

the answer is 
the area of the circle is 549.5 m²

The formula for potential energy is P = mgh. Solve the equation for h.
Liono4ka [1.6K]

Answer:

P = mgh

P/mg = h

We can divide both sides by mg, since both mass and gravity are being multiplied and not added.

Hope this helps!! :)
