Answer 1

Answer:

Step-by-step explanation:

Remark

The relationship that solves this is

The outside segment * the whole length of the secant = the outside segment of the other secant * the whole length of the second secant.

Put in symbolic (and hence easier language)

GF * EG = HG * SG

Givens

GF = 4

EG = 2x + 4

GH = 5

SG = x + 5

           

Equation

4*(2x + 4) = 5*(x + 5)               Remove the brackets

8x + 16 = 5x + 25                    Subtract 5x from both sides

8x - 5x + 16 = 25                    Combine

3x + 16 = 25                            Subtract 16 from both sides

3x = 25 - 16                        

3x = 9                                     Divide by 3

3x/3 = 9/3

x = 3

EF = 2 * 3

EF  = 6

So, Pythagoras theorem can be used,

Hypotenuse ² = base ² + altitude ²

AB²=AC²+BC²

11²=AC²+4²

11²-4²=AC²

121-16=AC²

Root 105=AC

AC=10.2 cm

The length of AC is 10.25 cm

What is pythagorean theorem ?

If ΔABC is a right angle triangle, then

AB² = BC²+AC²

where AB = Hypotenuse, BC & AC are adjacent sides of the right angle

What is the required length of the side ?

Given, hypotenuse = AB = 11 cm

One of adjacent sides = BC = 4 cm

We have to find the length of AC.

Using pythagorean theorem,

AB² = BC²+AC²

⇒ AC² = AB² - BC²

⇒ AC² = 11²-4²

⇒ AC² = 121-16

⇒ AC = √105

⇒ AC = 10.25

So the length of AC = 10.25 cm

Answers

Answer:

[tex]C=20+0.20N[/tex]

Step-by-step explanation:

Fixed monthly fee = $20

Amount charged per minute for long distance calls = $0.20

[tex]C[/tex] denotes total cost such that [tex]N[/tex] minutes are used for long distance calls.

Amount charged for [tex]N[/tex] minutes for long distance calls [tex]=0.20N[/tex]
