Answer:
A = 78.55
Step-by-step explanation:
A = nr^2
substitute the n and r values
A = 3.142(5)^2
Use PEMDAS
Parenthesis Exponents Multiply Divide Add Subtract
so the first step is exponents
5^2 is 25
A = 3.142(25)
Multiply
A = 78.55

Answer:
1/11x+4/11
Step-by-step explanation:
y=11x-4
x=11y-4
11y=x+4
y=1/11x+4/11
The simplified form of the expression is (12u⁵)/x³
<h3>Simplifying an expression </h3>
From the question, we are to simplify the given expression
The given expression is
6x⁻⁴v⁻⁸v⁸ × 2xu⁵
Simplifying
6x⁻⁴v⁻⁸v⁸ × 2xu⁵
From one of the laws of indices, we have that
x⁻ⁿ = 1/xⁿ
∴ v⁻⁸ = 1/v⁸
Thus,
6x⁻⁴v⁻⁸v⁸ = (6x⁻⁴v⁸) / v⁸
Then,
6x⁻⁴v⁻⁸v⁸ × 2xu⁵ = (6x⁻⁴v⁸) / v⁸ × 2xu⁵
= 6x⁻⁴ × v⁸/ v⁸ × 2xu⁵
= 6x⁻⁴ × 1 × 2xu⁵
= 6x⁻⁴ × 2xu⁵
= 6 × x⁻⁴ × 2 × x × u⁵
= 6 × 2 × x⁻⁴ × x × u⁵
= 12 × x⁻⁴ × x × u⁵
Also, from one of the laws of indices, we have that
∴ x⁻⁴ × x = x⁻⁴⁺¹
Thus,
12 × x⁻⁴ × x × u⁵ =
= 12 × x⁻⁴⁺¹ × u⁵
= 12 × x⁻³ × u⁵
= (12 × u⁵) / x³
= (12u⁵)/x³
Hence, the simplified form of the expression is (12u⁵)/x³

Answer:
(C). 
yd.
Step-by-step explanation:
b
Step-by-step explanation:
the pattern goes by 2s so you do 13 times 2 plus 4 which would be your 0th term because six is your first term so you add 4 and 26 you get 30 and it is not 33 because that is the 14th term
