7.3%??? I think that's it srry if me wrong
Answer:
31. (a) The height decreases by 12 feet each second towards the first floor
(b)
- After 3 seconds, the elevator is 144 feet above the first floor
- After 6 seconds, the elevator is 108 feet above the first floor
- After 9 seconds, the elevator is 72 feet above the first floor
(c) It takes 15 seconds for the elevator to get to the first floor
(d) The basement floor is 48 feet below the first floor
Step-by-step explanation:
<u>31 (a) explanation:</u>
An elevator is 180 feet above the first floor.
Each second, it descends 12 feet.
So the elevator's change in height each second is a decrease of 12 feet towards the first floor.
<u>31 (b) explanation:</u>
If the elevator goes down 12 feet, towards the first floor, in 1 second then;
- After 3 seconds it will be 180 feet - 3(12) feet = 144 feet above the first floor
- After 6 seconds it will be 180 feet - 6(12) feet = 108 feet above the first floor
- After 9 seconds it will be 180 feet - 9(12) feet = 72 feet above the first floor
<u>31 (c) explanation:</u>
If the elevator is 180 feet above the first floor and it takes 1 second to descend 12 feet,
Then it will take: × 1 second = 15 seconds reach the first floor.
<u>31 (d) explanation:</u>
From the first floor it takes 4 seconds to reach the basement floor
Therefore the basement floor is × 12 feet = 48 feet below the first floor
If angle TSV=6x+17 then arc it intercept (SV)would be double it
6x+17=1/2 (15x+13)
12x+34=15x+13
21=3x
x=7
Arc SV=15(7)+13
=118
And angle TSV=6(7)+17
=59
There are 360 degrees in a circle and the measure of the arc would be equal to the central point so the sum of all the arcs equals 360
Arc SV+ arc SUV=360
118+SUV=360
Arc SUV=242
