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:
It is 20.4 and 16.8
Step-by-step explanation:
This is similar to 8.4 (because its doubled) and it is similar to 10.2 (because its doubled)
Answer: D. 15
Step-by-step explanation:
Given : The revenue each season from tickets at the theme part is represented by
.
The cost to pay the employees each season is represented by
.
From the given graph , we can see that at 4th season, the profit = 15
Hence, the estimated profit after four seasons. =15
Solve for x:
4x-9 >= -21
Add 9 to both sides:
4x >= -12
Divide both sides by 4:
X >= -3
The number line would have a solid dot on -3 with a line and arrow pointing to the right of -3
