If x were 40, then Y would be
A) 20
Answer:
1. h(x) = 2ˣ-7 :
2ˣ - 7 = 131,065
2^x = 131,072
x = 17
2. k(x) = -(x/2) - 1 = 17
x/2 = -18
x = -36
3. g(x) = -(x-2)² = -36
x - 2 = 6
x = 8
4. f(x) = √x = 8
x = 64
h(k(g(f(64)))) = 131,065

Answer:
B. The radius
Step-by-step explanation:
The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle so we need to know the radius for it
Answer:
to know the summation of angles: (n-2)*180
here (n) represent numbers of sides
12)we have 5 sides (n=5)
(5-2)*180=540
x=540-(105+135+92+87)=121
13)we have 8 sides (n=8)
(8-2)*180=1080
x=1080-(116+158+141+124+136+132+129)=144

Answer:
it takes 1st person 4 hour and second person is 8 hours
Step-by-step explanation:
Let t is the time (t >0)
We have:
- 1st person working rate per one task: 1/t-8
- 2nd person working rate per one task: 1/t
- Working rate per one task from 2 person: 1/3
<=> 1/3 = 1/t + 1/t-8
<=>
<=>
<=> t - 7 = 5
<=> t = 12
So it takes 1st person 4 hour and second person is 8 hours
