Answer:
A(2 , 1) -> Q(2 , -1)
B(3 , 4) -> R(3 , -4)
C(5 , 3) -> S(5 , -3)
D(4 , 0) -> T(4 , 0)
Step-by-step explanation:
i took the test
(1/2)sin(2x) + C
−128
7. D:61
8. A:57
9. A: 47
Quesiton 7:
To find perimeter we add all the sides together.
x+2x+2x+5=145
Combine all the x's.
5x+5=145
To isolate the constants, subtract 5 from both sides.
5x=140
Now divide both sides by 5 to isolate the x.
x=28
The questions asks for the length of AC, so to find that we need to insert our new x.
AC= 2(28)+5
56+5=61
1) length of the field = 18 unit= 18*20=360 ft
2) circumference = 2(l+w)
2*(18*20+8*20)=1040
3) Area of the field = 18*8 units = 18*20*8*20ft^2 = 57600ft^2
Cost for the entire area= 57600*2.69= 170,000$
No it doesn't
if you try it on your own then you will get the answers
