Answer:
d
Step-by-step explanation:
The segment inside the triangle bisects the angle and divides the opposite sides into segments that are proportional to the other two sides, that is
= 
= 
( cross- multiply )
15x = 637.5 ( divide both sides by 15 )
x = 42.5 → d

Answer:
Step-by-step explanation:
If this is an exponential function, it is of the form
where x and y are coordinates from your table, a is the intial value, and b is the growth/decay rate. To find out what the equation is that represents this data, choose 2 points and solve first for a and then for b. Just a hint: If at all possible, choose the coordinate that gives you an x of 0. You'll see why in a minute.
I chose the first 2 points from your table: (0, .2) and (1, .8). Solving first for a:
The reason to choose the x of 0 as one of your points is because anything raised to the power of 0 is 1. So our equation then becomes:
so
a = .2 Easy enough.
Now use that value along with the other coordinate to solve for b:
b to the first is just b, so,
.8 = .2b
Divide both sides by .2 and you'll get that
b = 4
The equation, then, is
which is growth, since the value for b is greater than 1.
First, it is necessary to take out the i from the root. This is done by factoring out -1 as follows, using the relation √(-1) : = i
√-2 = √(-1)(2) = i<span>√2
</span>√-18 = √(-1)(2)(9) = 3i<span>√2
Simplifying by adding the two terms together:
</span>i√2 + 3i√2 = 4i<span>√2
</span>
Therefore the answer is B.
