Answer:
2πr is the formula to calculate
Step-by-step explanation:
Answer:
x = 7
Length = 4 inches , Width = 15 inches
Step-by-step explanation:
<em>PART</em><em> </em><em>1</em><em> </em><em>:</em>
Area of rectangle = Length × Width
A = L × W
L = x - 3
W = x + 8
Therefore:
A = L × W
60 = ( x - 3 ) ( x + 8 )
( x - 3 ) ( x + 8 ) - 60 = 0
x^2 + 8x - 3x - 24 - 60 = 0
x^2 + 5x - 84 = 0
x^2 + 12x - 7x - 84 = 0
x ( x + 12 ) - 7 ( x + 12 ) = 0
( x + 12 ) ( x - 7 ) = 0
THEREFORE:
x = - 12 , x = 7
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
<em>PART</em><em> </em><em>2</em><em> </em><em>:</em>
L = x - 3
L = ( - 12 ) - 3
L = - 15
OR
L = ( 7 ) - 3
L = 4
THEREFORE:
Length can not be a negative number. Hence, L can not equal to - 15.
L = 4 inches
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
W = x + 8
W = ( 7 ) + 8
THEREFORE:
W = 15 inches
To answer this question we need to find out the nth term
(aka the position-term rule) of this sequence. You'll notice that every term is the previous one multiplied by 2 - it's doubling each time. So we can say that the rule is 2ⁿ, where n is the position of the term in the sequence. Using the laws of exponents, 2ⁿ is equal to 2(2)ⁿ⁻¹. So the answer from the four options is 2(2)ⁿ⁻¹.
