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:
Function A is non-linear and Function B is linear.
Step-by-step explanation:
Linear function:
Has the following format:
y = mx + b
In which m is the slope and b is the y-intercept.
In a linear function, when x changes by 1, y will always changes by the same amount.
Function A:
When x changes by 1, y can change by various amounts. So function A is non-linear.
Function B:
y = -x + 5
In the format of a linear function, so linear
This is Right answer....

Answered already okay. GFY.
Answer:
12 miles in 4 hours is 3 mph
52-12=40 miles left
40 miles at 5 mph would take 8 hours
8+4=10
it took 10 hours to finish the trip.
