Mathematics
1 answer:
prisoha [69]2 years ago
4 0

Answer:

  • d) 1/(4p²)

Step-by-step explanation:

<u>Let's complete the square first:</u>

  • p⁴ - 2p²x² + x⁴ + x =
  • p⁴ + 2p²x² + x⁴ - 4p²x² + x =
  • (p² + x²)² - (4p²x² - x)

<u>In order the expression above to be a perfect square, we need:</u>

  • 4p²x² - x = 0

<u>Solve it for x:</u>

  • 4p²x² = x
  • 4p²x = 1
  • x = 1/(4p²)

Correct choice is d

If the hypotenuse of a right triangle is 20 cm and one of the legs is 16 cm, how long is the other leg?
siniylev [52]
Because this is a triangle and we know that we can use the Pythagorean Theorem to find the hypotenuse we just plug in the numbers. But because you have the hypotenuse already you will subtract the leg from the hypotenuse.

A^2+B^2=C^
16^2+B^2=20^2
256+B^2=400 subtract 256 from both sides
B^2=144 now take the square root of both sides
B=12

The second leg is 12 cm long. Your answer is B, the second answer.

Identify the volume and surface area of the hemisphere in terms of π. HELP ASAP!!
posledela

Answer:

D

Step-by-step explanation:

Use the formula for the SA of a hemisphere.

SA=2\pi r^2

Now we can find the radius of the hemisphere, which is 15.

Then, we can square that and multiply it by 2 to get 450.

Now, let's use the formula for the Volume of a hemisphere.

V=\frac{2\pi r^3}{3}

Now we can cube 15 and multiply it by 2 to get 6750.

Then we can divide this number by 3.

2250.

So the answer is D.

Find the value of y. Round your answer to nearest tenth. Please help
iren [92.7K]

9514 1404 393

Answer:

  (c)  52.0

Step-by-step explanation:

The angle whose cosine is 8/13 is found using the inverse cosine function:

  y° = arccos(8/13) ≈ 52.0°

  y ≈ 52.0

__

The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...

  =DEGREES(ARCCOS(8/13))

Divide 800ml into ratio 3:7
Brums [2.3K]
Simply take the numerator (3) and denominator (7) and add them together. 

3+7 = 10, which means that the ratio will provide parts that are in multiples of 10 depending on the total

so take 10x = 800 

x = 80.

Then multiply this by the numerator and denominator 

3*80/7*80 = 240/560.
