Answer:
(i) The equivalent coordinates in rectangular form are 
.
(ii) The equivalent coordinates in rectangular form are 
.
Step-by-step explanation:
In this exercise we must find the equivalent coordinates in rectangular form from polar form. That is:
Where:
- Norm of vector, dimensionless.
- Direction of vector with respect to +x semiaxis, measured in sexagesimal degrees.
(i) (
, 
)
The equivalent coordinates in rectangular form are .
(ii) (
, 
)
The equivalent coordinates in rectangular form are .
B because if you reflect on x= -1 it would look like the “y” line moved to the left one because it’s x= -1, So you reflect along that new line. Then translate down the amount it said to. Hope this made sense
Answer:
A
Step-by-step explanation:
Answer:
Number of Large Pizzas: 30
Number of Medium Pizzas: 8
Number of Small Pizzas: 27
Step-by-step explanation:
L = # of large Pizzas
M = # of medium Pizzas
S = # of small Pizzas
Amount:
L = 4M - 2
S = 3M + 3
Cost:
21L + (I'm assuming you meant 14) 14M + 7S = 931
Plus in the Amounts to the Cost:
21(4M - 2) + 14M + 7(3M + 3) = 931
84M - 42 + 14M + 21M +21 = 931
Combine like terms:
119M - 21 = 931
Isolate the Variable:
119M - 21 + 21 = 931 + 21
119M = 952
119M/119 = 952/119
M = 8
Plug it into the Amount equations:
Large: L = 4(8) - 2
L = 32 - 2
L = 30
Small: S = 3M + 3
S = 3(8) + 3
S = 24 + 3
S = 27
Check your work (plug the values into Cost.):
21(30) + 14(8) + 7(27) = 931
630 + 112 + 189 = 931
931 = 931
