I would be able to help but I need it to be in English
Answer:
answer is B
it is less than Zx for set B
Step-by-step explanation:
For this case we must find the inverse of the following function:
For them we follow the steps:
We change f (x) to y:
We exchange variables:
We solve for "y":
We add 1 to both sides of the equation:
We apply square root to eliminate the exponent:
We change y by 
:
Answer:
Option D
<span>No. Of hours after passenger train passed the station x:
</span>52x = 32(x + 2)
<span>13x = 8(x + 2) </span>
<span>13x = 8x + 16 </span>
<span>5x = 16 </span>
<span>x = 16/5 or 3 1/5
</span>
Answer:
<span>3 1/5 hours OR 3 hrs 12 min
</span>
Hope this helps!
C = Pi * d where C = circumference, d = diameter, r = radius
C = 2*pi *r
we need to watch the units since they are different
Pool A
C = 2 * pi * r
C = 2 * pi * 12 = 24 * pi in feet
Pool B
C = pi * d
change meters to feet
7.5 m * 3.28 ft/ 1 m = 24.6 ft
C = pi * 24.6 = 24.6* pi in ft
Pool B had a greater circumference
24.6 * pi > 24 pi
