8 0

Answer:

n = 8 cm

Step-by-step explanation:

When two chords intersect each other inside a circle, the products of their segments are equal

Look to the attached figure

In the circle two chords are intersected at a point inside it

∵ The two chords are intersected in a point inside the circle

∴ The product of their segments are equal

∵ The segments of one chord are 4 centimeters and 6 centimeters

∵ The segments of the other chords are n and 3 centimeters

- Multiply each two segments and equate their products

∴ n × 3 = 4 × 6

∴ 3 n = 24

- Divide both sides by 3

∴ n = 8

∴ The value of n is 8 centimeters

If 3x / 4 = 7 - x / 3, then x = what?
Alja [10]
\frac{3x}{4} = 7-\frac{x}{3} 


\frac{3x*3}{4*3} =  \frac{7*12}{12} -\frac{x*4}{3*4} 


\frac{9x}{12} = \frac{84}{12} -\frac{4x}{12}
12*( \frac{9x}{12} = \frac{84}{12} -\frac{4x}{12} )
9x=84-4x

13x=84

y is inversely proportional to a^3. When a=2, y=10. a is directly proportional to x. When x=4, a=20. Find a formula for y in ter
marshall27 [118]

Answer:

<h2>y = 16/25x³</h2>

Step-by-step explanation:

If y is inversely proportional to a^3, this is expressed as;

y∝1/a³

y = k/a³ where k is the proportionality constant

Given a=2, y=10, then 10 = k/2³

k = 10*2³

k = 80

Substituting k = 80 back into the formula;

y = 80/a³ ............. 1

Similarly, if a is directly proportional to x, then a ∝ x i.e a = kx

If x=4, a=20 then;

20 = 4k

k = 20/4

k = 5

Substituting k = 5 back into the formula;

a = 5x ....... 2

Substitute equation 2 into 1;

y = 80/a³

y = 80/(5x)³

y = 80/125x³

y = 16/25x³

<em>Hence the formula for y in terms of x is y = 16/25x³</em>

#2 <br> #3 <br> Need help for my discrete math class
miss Akunina [59]

For (2), start with the base case. When n = 2, we have

(n + 1)! = (2 + 1)! = 3! = 6

2ⁿ = 2² = 4

6 > 4, so the case of n = 2 is true.

Now assume the inequality holds for n = k, so that

(k + 1)! > 2ᵏ

Under this hypothesis, we want to show the inequality holds for n = k + 1. By definition of factorial, we have

((k + 1) + 1)! = (k + 2)! = (k + 2) (k + 1)!

Then by our hypothesis,

(k + 2) (k + 1)! > (k + 2) 2ᵏ = k•2ᵏ + 2ᵏ⁺¹

and k•2ᵏ ≥ 2•2² = 8, so

k•2ᵏ + 2ᵏ⁺¹ ≥ 8 + 2ᵏ⁺¹ > 2ᵏ⁺¹

which proves the claim.

Unfortunately, I can't help you with (3). Sorry!
