Euclid and Apollonius stand on two seperate portions which Apollonius 12 meters due worth and 9 meters due East of Euclid. Meanw
Alexeev081 [22]
Draw a diagram to illustrate the problem as shown in the figure below.

Euclid is placed at the origin at (0,0).
Apollonius is 12 m north and 9 m east of Euclid, so its coordinate is (9,12).
Pythagoras is at the arbitrary position (x,y) so that is is at distance d from Euclid and 2d from Apollonius.

From the distance formula, obtain
d² = x² + y²                            (1)
(2d)² = (x-9)² + (y-12)²
or
 4d² = (x-9)² + (y-12)²             (2)

Substitute (1) into (2).
4(x² + y²) = x² - 18x + 81 + y² - 24y + 144
3x² + 3y² + 18x + 24y = 225
Divide by 3.
x² + 6x + y² + 8y = 75
Create perfect squares.
(x+3)² - 9 + (y+4)² - 16 = 75
(x+3)² + (y+4)² = 10²

Answer:
The path of Pythagoras is a circle of radius 10 m, centered at (-3, -4).

khairul order one set meal at a restaurant which offer a 20% discount. there is a service charge of 10% and GST is at 7% given t
fenix001 [56]

Answer:

Market price of set = 25.14

Step-by-step explanation:

Given:

Discount percentage = 20%

Service charge = 10%

GST = 7%

Amount pays = 23.54

FInd:

Market price of set

Computation:

Assume;

Market price of set = a

Market price of set after discount = a(1-20%)

Market price of set after discount = 0.80a

Market price of set after discount + (Market price of set after discount)(Service charge) + (Market price of set after discount)(GST) = Amount pays

0.80a + (0.80a)(10%) + (0.80a)(7%) = 23.54

0.80a + 0.08a + 0.056a = 23.54

0.936a = 23.54

a = 25.14

Market price of set = 25.14
