Answer:
the blank contains the term 2⁴²
Step-by-step explanation:
The Equation given in the question (2²¹ − 1)(2²¹ +1)
on evaluating the above expression,
we have
⇒ 2²¹ × (2²¹ + 1 ) -1 × (2²¹ + 1)
or
⇒ 2²¹⁺²¹ + 2²¹ - 2²¹ - 1² (using the property Xᵃ × Xᵇ = Xᵃ⁺ᵇ)
or
⇒ 2⁴² + 0 - 1
or
⇒ 2⁴² - 1
on comparing the result with LHS, we have
therefore,
the blank containing the term 2⁴²

Answer:
Step-by-step explanation:
the appropriate null and alternative hypotheses's are something
a) 4.71ft
b) 3.53ft^2
Step-by-step explanation:
Perimeter is 1/2 the circumference
1/2 Circumference = 2*pi*radius
Radius = 1/2 Diameter
Radius = 3/2 = 1.5ft
Circumference = 2*pi*1.5ft = 9.42
1/2 Circumference = 4.71
4.71ft is the perimeter.
The area is 1/2 that of a full circle
A = pi*r^2
A = 3.14*1.5*1.5
A = 7.065ft^2
1/2 A = 3.53ft^2
