Answer:
0.40 foot
Step-by-step explanation:
In the first case, a 50 - foot building casts a- foot shadow (1-foot). Let the angle of elevation of the sun from the shadow be represented by θ.
Then:
Tan θ = 
Tan θ = 
Tan θ = 50
⇒ θ = 
50
= 88.8542
= 
The angle of elevation is approximately .
For a 20-foot pole,
Tan θ =
Tan = 
x = 
= 0.4015
= 0.40 foot
The length of the shadow of the pole is 0.40 foot.
Notice that it starts at x = 0 with closed dot then it goes to the right.
So the domain would be {x | x ≥ 0}
Hope this helps.
Answer:
22 yd
Step-by-step explanation:
Length is four times its width -----> L=4W
area of rectangle is 196 -----> 196=LW
Plug L=4W into 196=LW giving you 196=(4W)W
Simplify a bit 196=4W^2
Divide both sides by 4: 196/4=W^2
Simplify a bit: 49=W^2
Square root both sides: 7 or -7=W
The width is 7 yd
The length is 4(7)=28 yd
Now its final part is for you to find the perimeter of this rectangle. The rectangle is a 7 yd by 4 yd rectangle.
Double both then add.. 14+8=22 yd
27/25 is in the lowest form
