Hi! Can anyone with knowledge on writing Geometry proofs help me? I need assistance with answering this question with a two colu

Neporo4naja [7]

We will prove first that PRQ≡PSQ
We need 3 attributes from the each triangle:
QS=QR
PR=PS
PQ=PQ

from PRQ≡PSQ => angles RPQ and SPQ are equal

Let if be O=RS∩PQ

We will prove that triangles RPO≡SPO
We need 3 attributes from the each triangle:
RP=PS
PO=PO
angles RPQ and SPQ are equal

results that angles RPO and SPO are equal(Let's note them with x)
We also know that (as angles) POS≡ROS and POR≡SOQ as opposite angles

We now have than 4x=360 wich means x=90. And we proved the desired result.
You just need to put this explanation into the table. (most if the 3 attributes for each triangle)

Classify the shapes based on their volumes.

shepuryov [24]

Answer:

1. volume of cone = 288π cube units

2. volume of cylinder = 972π cube units

3. volume of sphere = 288π cube units

4. volume of cylinder = 288π cube units

5. volume of sphere = 972π cube units

6. volume of cone = 972π cube units

Step-by-step explanation:

1. Radius of cone (r) = 12units

height of cone(h) = 6units

volume of cone = π/3r²h

=π/3.12.12.6

=π.12.12.2

=288π cube units

2. diameter of cylinder(d) = 12units

radius of cylinder (r) = 6units

height of cylinder (h) = 27 units

volume of cylinder = πr²h

= π.6.6.27

= 972π cube units

3. diameter of sphere = 12 units

radius of sphere = 6 units

volume of sphere = 4π/3.r³

= 4π.2.6.6

= 288π cube units

4. diameter of cylinder (d) = 8 units

radius of cylinder (r) = 4 units

height of cylinder(h) = 18units

volume of cylinder = πr²h

= π.4.4.18

= 288π cube units

5. radius of sphere(r) = 9 units

volume of sphere = 4π/3.r³

= 4π/3.9.9.9

= 4π.3.9.9

= 972π cube units

6. diameter of cone (d) = 18 units

radius of cone (r) = 9 units

height of cone (h) = 36 units

volume of cone = π/3.r².h

= π/3.9.9.36

= π.3.9.36

=972π cube units

(0,1),(2,5),(3,7) in an equation

12345 [234]

The equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.

Step-by-step explanation:

Step 1; We need to determine the equation relating the x to the f(x) values from the given coordinates. y is the dependent value whereas x is the independent value i.e. y's value depends on x's value.

Step 2; If we multiply the x value with 2 and add the resulting answer with 1 we get the y value.

y = 2x + 1 is the equation that relates the values in the table.

Step 3; Now we substitute the values in the equation to see if it's correct.

For x = 0, y = 2(0) + 1 = 0 + 1 = 1,

For x = 2, y = 2(2) + 1 = 4 + 1 = 5,

For x = 3, y = 2(3) + 1 = 6 + 1 = 7.

So the equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
