4n= 9+7
4n= 16
n= 16/4
N= 4
Base area = 12 x 12 = 144 unit²
Volume of the pyramid = 1/3 x 144 x 8 = 384 unit³
Answer: 384 unit³ (Answer B)
Answer:
∝ for portfolio A = E(rA) - Required return predicted by CAPM
= 0.11 - [0.06 + 0.8 × (0.12 - 0.06)]
= 0.11 - [0.06 + 0.048]
= 0.11 - 0.108
= -0.002 ≈ -0.2% to 1 decimal place
∝ for portfolio B = E(rB) - Required return predicted by CAPM
= 0.14 - [0.06 + 1.5 × (0.12 - 0.06)]
= 0.14 - [0.06 + 0.09]
= 0.14 - 0.15
= -0.01 ≈ -1.0% to 1 decimal place
Hello:
2x+3y=8
y =(-2/3)x+8/3 (the slope is : (-2/3) )
<span>an equation of the line through (-1,4) and perpendicular to 2x+3y=8</span>
<span> is : y = ax+b
the slope is a : a×(-2/3) = -1......(
perpendicular to a line with a slope of -2/3)
a = 3/2 y=(3/2)x+b
the line that passes through (-1, 4) :4 =
(3/2)(-1)+b
b =11/2
the equation is : y = (3/2)x+11/2</span>
Answer:
x=2
Step-by-step explanation:
Step 1: Factor left side of equation.
(3x+1)(x−2)=0
Step 2: Set factors equal to 0.
3x+1=0 or x−2=0
