Answer: a) Length of wire to replace old one=9ft
b) Length of wire=3.09ft
Leftover wire=0.91ft
Step-by-step explanation: from the right angle triangle, Tan&=20/15
&=53.13°
Length of wire,x=cos 31.13=x/15
15cos31.13
X=9
b) Tan&=10/6
Tan^-110/6
&=59.05
Length= 6cos59.04
X=3.09
4-3.09=.91= leftover wire
Answer: T-birds and bulldogs
Explanation:
T-bird has 15 win and 5 lose so the ratio is 15/5 = 3
Bulldogs has 12 win and 4 lose so the ratio is 12/4 = 3
Therefore, their ratio are equivalent
Answer:
roots (1,0) (3,) the vertical intercept is (0,-12)
Step-by-step explanation:
R^4-2(r-14)>0
r^4-2r+28>0
r^4-2r+28=0
There is no real solution but there is all real numbers
