X + k y = 1
k x + y = 1 / * ( - k )
----------------
x + k y = 1
- k² x - k y = - k
--------------------
x - k² x = 1 - k
x ( 1 - k² ) = 1 - k
x = ( 1 - k ) / ( 1 - k² ) = ( 1 - k ) / ( 1 - k ) ( 1 + k )
y = 1 - k( 1 - k )/( 1 - k² )
y = ( 1 - k ) / ( 1 - k² ) = ( 1 - k ) / ( 1 - k ) ( 1 + k )
a ) For k = - 1 this system has no solution.
b ) For k ≠ - 1 and k ≠ 1, the system has unique solution:
( x , y ) = ( 1/ (1 + k) , 1/( 1 + k ) ).
c ) For k = 1, there are infinitely many solutions.
Answer:
87.6m²
Step-by-step explanation:
From the above question, we are given the following information
The dimensions of the base were 3 m by 5 m:
Length = 3m
Width = 5m
The pyramid was 3.6 m high
Height = 3.6m
To calculate the amount of ice needed for this sculpture, we would have to find the Surface Area of the Rectangular Prism
This is calculated as:
Surface Area =2(wl+hl+hw)
= 2(3 × 5 + 3.6 × 3 + 3.6 × 5)
= 2(15 + 10.8 + 18)
= 2(43.8)
= 87.6m²
The amount of ice needed for this sculpture is 87.6m²
Just multiply 37.7 by 4 and get your answer.
The inverse function is {}
Given:
$1,750
Rate = $1 = CLP 496.50
Spent : 217,513 pesos
Rate = CLP 1 = VEF 0.1283
Spent : 38,422.19 bolivars
Rate = VEF 1 = PGY1063.95
Spent : 12,857,441.39 guarani
Rate = PYG 1 = $0.00002186
$1750 * CLP 496.50 = CLP 868,875
CLP 868,875 - 217,513 = CLP 651,362
CLP 651,362 * VEF 0.1283 = VEF 83,569.7446
VEF 83,569.7446 - 38,422.19 = VEF 45,147.5546
VEF 45,147.5546 * PYG 1063.95 = PYG 48,034,740.70
PYG 48,034,740.70 - 12,857,441.39 = PYG 35,177,299.30
PYG 35,177,299.30 * $0.00002186 = $768.976763 ⇒ $768.98
