natita [175]

Answer:

1. The tetrahedron has 4 vertices, 6 edges and 4 faces. Then V-E+F=4-6+4=2

2. The cube has 8 vertices, 12 edges and 6 faces. Then V-E+F=8-12+6=2

3. The octahedron has 6 vertices, 12 edges and 8 faces. Then V-E+F=6-12+8=2

4. The icosahedron has 12 vertices, 30 edges and 20 faces. Then V-E+F=12-30+20=2

5. The dodecahedron has 20 vertices, 30 edges and 12 faces. Then V-E+F=20-30+12=2.

What is the difference??

Goryan [66]

9/x^2 - (2x + 1)/8x = 72/8x^2 - x(2x + 1)/8x^2 = (72 - x(2x + 1))/8x^2 = (-2x^2 - x + 72)/8x^2. C is the correct answer.

A pilot knows she descended 1,000 feet and traveled a diagonal distance of 18,000 feet.

Arada [10]

The horizontal distance covered by pilot is 17,972.2 feet.

Step-by-step explanation:

Given,

Distance covered descending = 1000 feet

Diagonal distance = 18,000 feet

The horizontal distance will form a right triangle, therefore, we can find the horizontal distance by using pythagoras theorem.

Here,

a = 1000

b = horizontal distance

c = 18000

$a^2+b^2=c^2\\(1000)^2+b^2=(18000)^2\\1000000+b^2=324000000\\b^2 = 324000000-1000000\\b^2=323000000$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{323000000}\\b=17972.2$

The horizontal distance covered by pilot is 17,972.2 feet.
