To get how close the windmill is to the fire we proceed as follows:
distance from watch tower to the fire will be:
tan θ= opposite/adjacent
opposite=140 ft
adjacent=x
θ=3°
hence
tan 3=140/x
x=140/tan 3
x=2,671.36 ft
the distance from watch tower to windmill will be:
tan θ=opposite/ adjacent
θ=8°
opposite=140 ft
adjacent=y
thus
tan 8=140/y
y=140/tan8
y=999.15 ft
the distance between fire and wind mill will be:
2,671.36-999.15
=1675.21~1675 ft (to the nearest ft)
Answer:
The first one. L (t) = 0.37t + 39.67
Step-by-step explanation:
The "0.37t" is about 0.37 years of life expectancy added for each year that passes the "+ 39.67" is the starting life expectancy that has to be added to whatever the rising trend may be. just multiply 0.37 by 20 and youl have the rising trend.
Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:
The arithmetic sequence is given by:
Putting the values
Hence,
The function will be: f(n) = 2n
Answer:
1005 in^3
Step-by-step explanation:
Think of this cake as a cylindrical solid of base radius 8 in and height 5 in.
The volume is V = (base area)(height), which here is:
V = (pi)*(8 in)^2*(5 in) = 320pi in^3, or approximately 1005 in^3
A.
the area of a polygon is/
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=
