Answer:
L = the length of the field
W = the width of the field
The First Question:
The system is: L - 12 = w
2L + 2W = 76
Plug in L - 12 for W and you will get
2L + 2L - 24 = 76
4L -24 = 76
4L = 100
L = 25
To find W do L - 12 = w
25 - 12 = w
w = 13
if you were to use the first ordered pair, your answer would be y - 2 = 11/3(x-7) and with the second ordered pair : y + 9 = 11/3(x-4
A6 = -8
a15= -62
There are (15 - 6) terms in between, therefore 9 terms in between.
-8 to -62 ... there is a difference of 54
54 ÷ 9 = 6
Therefore it gets -6 each term.
a6 = -8, a7= -14, a8 = -20 ......
Answer:
its A
Step-by-step explanation:
b^2 = 6^2 + 11^2 - 2*6*11cos 109 = 199.97
b = 14.1 to nearest tenth.
now use sine rule to find the value of < A
14.14 / sin 109 = 6 / sin A
<A = 24 degrees
<C = 180 - 24 - 109 = 47 degrees
<3
