6 blades in 1 windmill is the "unit rate" A unit rate is the number per thing. You will need to multiply. Multiply 6X7. 6 for 6 blades and 7 for 7 windmills. It is 42. 42 blades are in 7 windmills.
Since <em>x</em> ² + 8<em>x</em> + 7 = (<em>x</em> + 7) (<em>x</em> + 1), we have for <em>x</em> ≠ -7,
<em>y</em> = (<em>x</em> + 7) / (<em>x</em> ² + 8<em>x</em> + 7) = 1/(<em>x</em> + 1)
so <em>y</em> is undefined at <em>x</em> = -1, indicating a vertical asymptote, and there is a hole/removable discontinuity at <em>x</em> = -7. Then the answer is D.
Answer:
$89,472.58
Step-by-step explanation:
P = $82100
r = 4.3% = 4.3/100 = 0.043
T = 2 years
V = P × e^rt
V = 82100 × e^(0.043 × 2)
V = 82100 × e^(0.086)
V = 82100 × 1.0898
V = 89,472.58
The interest after 2 years is $89,472.58
So the answer would be x=1 and y=-2. Hope this helps
