Answer:
Paul purchased 23 pieces of pepperoni pizza
Step-by-step explanation:
Let pepperoni pizza pieces = x
and plain pizza pieces = y
So, the equations will be:
AS pepperoni pizza piece is sold for $1.15 and plain pizza is sold for $0.90 and Paul paid $39.05
1.15 x + 0.90 y = 39.05 eq(1)
Paul bought total 37 pieces of pizza so,
x + y = 37 eq(2)
Solving eq(1) and (2) we can find the pieces of pepperoni pizza bought by Paul.
Multiplying equation (2) with 1.15 and subtracting eq(1) and eq(2)
1.15 x + 0.90 y = 39.05
1.15 x + 1.15 y = 42.55
- - -
__________________
0 x - 0.25 y = -3.5
y = -3.5/-0.25
y = 14
Putting value of y in equation(2)
x+y = 37
x + 14 = 37
x = 37 - 14
x = 23
So, Paul purchased 23 pieces of pepperoni pizza as x represents pepperoni pizza pieces.
So the answer is 5.336 but if we round you would get 5.
(1+x^2)^8
=(1+8x^2+8*7/(1*2)x^4+8*7*6/(1*2*3)x^6+8*7*6*5/(1*2*3*4)x^8+....)
=1+8x^2+28x^4+56x^6+70x^8+....)
For x<1, higher power terms diminish in value, hence we can approximate powers of numbers.
1.01=(1+0.1^2) => x=0.1 in the above expansion
(1.01)^8
=1+8(0.1^2)+28(0.1^4)+56(0.1^6) [ limited to four terms, as requested]
=1+0.08+0.0028+0.000056 (+0.00000070)
=1.082856 (approximately)
