Answer:
this cant be simplified unless you have an integer in place of "i"
All of the telephones * all of the telephones minus one (because one is in use)
85 * 84 = 7140 connections
Answer:
400 ft
Step-by-step explanation:
h(t)= -16t^2 + 160t
The vertex is found at
h = -b/2a where b is the coefficient of t and a is the coefficient of t^2
= -160/(2*-16)
-160/-32
5
The time where the maximum occurs is at t=5
To find the maximum substitute into the function
h(5) = -16 (5)^2 +160*5
= -16*25 +800
=-400+800
= 400
The maximum height is 400 ft
The answer is 37.
Explanation:
first quartile is where the box starts at
the no must be 858 o 868 or 878 or 888 or 898
8+5+8=21
8+6+8=22
8+7+8=23
8+8+8=24
8+9+8=25
now 898 is the most likely case here
lets go deep into it
approximating 898 to nearest hundred gives 900
addition of each character of 898 gives 25
reading forward and backward both 898 remains same
therefore 898 is the number which satisfies the given conditions. therefore the answer is 898
