The amount of balls in a given layer can be found by squaring the layer it is in
4 layers
top layer (1st) is 1
2nd is 4
3rd layer is 9
4th is 16
add them up
1+4+9+16=30
30 in that pyramid
She should chose the $9 because it is cheaper ;)
Answer:
Step-by-step explanation:
90÷4=22.5
30+20+20+20=90
original number with greatest value are 34,24,23,22
greatest sum=34+24+23+22=103
If two sets are same let a and bthen we can say a= b
according to definition of intersection it is function that contains common enements from both setsas a=b so all elemnts are commonso a= a n bor b = a n b
in union the function has all elements of both sets and in set no element repeats so
a u b = aor a u b = b
as a u b = a or b and a n b = a or b so we can conclude here that
a u b = a n b as a = b // defined above
I gather that the given functions satisfy the following definite integral relations:



a) By linearity of the integral operator, we have

b) The integral over an interval is equal to the sum of integrals over a partition of that interval. In this case, the interval [-1, 5] can be written as the interval union [-1, 4] U [4, 5], so that

c) By linearity,

d) By linearity,
