If x=3+bi, then
You know that 
then
Two possible complex numbers satisfy these conditions:
As you can see the possible value of b is 2.
Answer: correct choice is A.
Answer: 6 m
Step-by-step explanation:
The area of a rectangle is the length times the width.
We can set up an equation.
108 m^2 = 18 m * width
Width = 6 m
Answer:
with what?
Step-by-step explanation:
When x<span> approaches to </span><span>+∞</span><span> the function </span><span>e^<span>3x</span></span><span> becomes much bigger then </span><span>e^<span>−3x</span></span><span>, which obviously means that </span><span>e^<span>−3x</span></span><span> can be neglected in both numerator and denominator.
</span><span>
Here's how I figured this out:
</span><span>lim <span>x →+∞ </span></span>= (<span><span><span>e^(<span>3x))</span></span>− (<span>e^(<span>−3x)) / (</span></span></span><span><span>e^<span>3x)) </span></span>+ (<span>e^(<span>−3x)) </span></span></span></span>= <span>lim <span>x → +∞ </span></span><span><span>e^<span>3x / </span></span><span>e^<span>3x </span></span></span>= 1
Answer:
y ≈ 9.24
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos30° = 
= 
( multiply both sides by y )
y × cos30° = 8 ( divide both sides by cos30° )
y = 
≈ 9.24 ( to the nearest hundredth )
