Answer:
59.03° is greater than 56.31°' This means that the sliding pole that rises 5 feet for every 3 feet of run making an angle of inclination of 59.03° is steeper than the angle of inclination made by a sliding pole that rises 3 feet for every 2 feet run.
Step-by-step explanation:
Step 1
Express the angle of inclination as follows;
Tan∅=H/R
where;
∅=angle of inclination
H=vertical rise
R=distance of run
Step 2
Determine the angle inclination when;
H=3 feet
R=2 feet
replacing;
Tan∅=(3/2)=1.5
∅=Tan^(-1)(1.5)
∅=56.31°
Determine the angle inclination when;
H=5 feet
R=3 feet
replacing;
Tan∅=(5/3)=1.67
∅=Tan^(-1)(1.67)
∅=59.03°
59.03° is greater than 56.31°' This means that the sliding pole that rises 5 feet for every 3 feet of run making an angle of inclination of 59.03° is steeper than the angle of inclination made by a sliding pole that rises 3 feet for every 2 feet run.
D.) There are always 180 degrees in triangles. 147 is already shown, so subtract that from 180. That gives you 33.
Speed = distance / time
so ur speed = (3/5) / (3/8) = 3/5 * 8/3 = 8/5 or 1 3/5 miles per hr.
its the first answer choice
Answer:
series is 15, 75, 375, 1875, 9375, 46875, 234375
Step-by-step explanation:
r=5
an = 234,375
n = 7
a1 = ?
a1 = an /rn-1
a1 = 234,375 /57-1
a1 = 15
a2 = 15*5 = 75
a3 = 15*25 = 375
a4 = 15*125 = 1875
a5 = 15*625 = 9375
a6 = 15*3125 = 46, 875
a7 = 15*15,625 = 234,375
Hence series is 15, 75, 375, 1875, 9375, 46875, 234375
