HELP!!!! NO LINKS!!!!! Anthony has a sink that is shaped like a half-sphere. The sink has a volume of 2000/3-TT (pi) (in^3) One

day, his sink clogged. He has to use one of two cylindrical cups to scoop the water out of the sink. The sink is completely full when Anthony begins scooping.
One cup has a diameter of 4 in. and a height of 8 in. How many cups of water must Anthony scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number.

Identify any extraneous solution. See above pic
Sav [38]

Answer:

There are no extraneous solutions

Reasoning:

An extraneous solution is a solution that isn't valid, it might be imaginary like the square root of a negative number.

first we want to isolate z:

1+sqrt(z)=sqrt(z+5)

^2 all      ^2 all

(1+sqrt(z))(1+sqrt(z))=z+5

expand

1+2sqrt(z)+z=z+5

-1              -z  -z -1

2sqrt(z)=4

/2           /2

sqrt(z)=2

^2 all    ^2 all

z=4

Since there is one solution and it is a real number, there are no extraneous solutions.

Answer:

The measure of angle B is 33 Degrees.

Step-by-step explanation:

The triangles are said to be similar. then their corresponding angles are equals.

\angle A  =  \angle M

\angle B  =  \angle O

\angle C  =  \angle P

Then from the given data,

\angle A  =  \angle M = 45^{\circ}

\angle C  =  \angle P = 102^{\circ}

Now according to the triangle sum property,

\angle A +  \angle B +\angle C = 180^{\circ}

45^{\circ} +  \angle B + 102^{\circ} = 180^{\circ}

147^{\circ} +  \angle B  = 180^{\circ}

\angle B  = 180^{\circ} - 147^{\circ}

\angle B  = 33^{\circ}

Find the distance between the points (5, -3) and (0, 2).
ohaa [14]

Answer:

Distance between points  (5, -3) and (0, 2) is √50 or 7.07

Step-by-step explanation:

We need to find distance between two points (5,-3) and (0,2)

The distance formula used is:

d= \sqrt {\left( { x_2-x_1 } \right)^2 + \left( {y_2-y_1} \right)^2 }

here

x₁= 5, y₁=-3, x₂=0 and y₂=2

Putting values in the formula:

d= \sqrt {\left( {x_2-x_1} \right)^2 + \left( {y_2-y_1} \right)^2 }\\d= \sqrt {\left( {0-5} \right)^2 + \left( {2-(-3)} \right)^2 }\\d= \sqrt {\left( {-5} \right)^2 + \left( {2+3} \right)^2 }\\d= \sqrt {25+25}\\d= \sqrt {50}\\d= 7.07

So, distance between points  (5, -3) and (0, 2) is √50 or 7.07

If f(x) = 2x2 + 1, what is f(x) when x = 3?<br> O 1<br> O 7<br> O 13<br> O 19
Slav-nsk [51]

Answer:

19

Step-by-step explanation:

f(x) = 2x^2 + 1

Let x= 3

f(3) = 2 * (3)^2 +1

Exponents first

     = 2 * 9+1

Then multiply

     = 18+1

Add

   = 19
