Answer:
10.53
Step-by-step explanation:
Given :
Height of building = 17m
John's eye level = 2 m
Total height (including eye level) = 17+2 = 19m
Angle of depression, θ = 61°
Let distance between John's friend and building = d
Using trigonometry :
Tan θ = opposite / Adjacent
Tan 61° = 19 / d
1.8040477 = 19 / d
d = 19 / 1.8040477
d = 10.53

1) 6x^2+12x-48
6. (x^2+2x-8)= 6. (x+4). (x-2)
2) 6x^2-12x-48
6. (x^2-2x-8)= 6. (x-4). (x+2)
Answer: option C is the correct answer.
Step-by-step explanation:
The natural gas company charges a $17.01 connection fee plus $1.88 per 8 cubic feet of gas used.
If a family uses 96 cubic feet of gas, their original bill would be
17.01 + (1.88 × 96)/8
= 17.01 + 22.56 = $39.57
In the winter peak usage months, November through February, they charge each customer a peak usage surcharge of $27.43.
Therefore, the amount by which their bill would increased because of the peak usage surcharge is
39.57 + 27.43 = $67
Answer:
174 ft squared
Step-by-step explanation:
6*20=120
3*18=54
54+120=174
4x-2y=10
4x=10+2y
4x-10=2y
(4x-10)/2=y
(4(-2)-10)/2=-9
