Answer:
a = 13
b = 0
Step-by-step explanation:
Conjugate of -3 + 2i is -3 - 2i
(-3 + 2i) (-3 - 2i)
We need to expand:
9 + 6i + -6i + -4i^2
-4i^2 =(-4)(-1) = 4
9 + 4 = 13
a = 13
b = 0

Step-by-step explanation:
Hello There!
We can solve for x using trigonometry
More specifically the law of sines
In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)
so to find x we use this equation
step 1 multiply each side by sin 59
now we have
so we can conclude that x = 14.6
Step-by-step explanation:
just going tell u to use math
way
We know the equation for company A is P(t) = 1.8(1.4)ᵗ.
and what we know about company B is that their equation is linear, and we also have 3 months in a table of values, and we can simply use two points from there to get the equation of company B, let's do so using (3,5) and (7, 25),
now, the end of the year will be at the twelfth month, namely t = 12, and the four month well we know that t = 4.
how did each one fare?
so, notice, on the fourth month B did better than A, but at the end of the year, A ended up better off than B.
