Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.
Answer:
She can buy 3 bracelets.
Step-by-step explanation:
$50 (Total price) - $12 (Airpod case) = $38
$38 - $9.50 (Bracelets) = $28.5
$28.5 - $9.50 = $19
$19 - $9.50 = $9.5
Answer:
D
Step-by-step explanation:
The perimeter (circumference) = 28 * PI.
This means the diameter = 28.
The area = PI*radius^2
area = PI * 14^2
area = PI *

speed of current is 1.5 mi/hr
Answer:
let the rate in still water be x and rate of the current be y.
speed down the river is:
speed=distance/time
speed=14/2=7 mi/h
speed up the river is:
speed=(14)/(3.5)=4 mi/hr
thus total speed downstream and upstream will be:
x+y=7...i
x-y=4.......ii
adding the above equations i and ii we get:
2x=11
x=5.5 mi/hr
thus
y=5-5.5=1.5 mi/r
thus the speed in still waters is 5.5 mi/hr
speed of current is 1.5 mi/hr
