Let a = 2 cm, b = 6 cm, and angle A = 60°. How many solutions are there for angle B
We must calculate b sin A. If it is less than a, there will be two solutions. If it is equal to a, there will be one solution. And if it is greater than a, there will be no solution.
Now, sin 60° =
31/2/ 2
Therefore,
b sin A
= 6·
=
3.31/2
.
Since a = 2, then b sin A > a. (31/2 = 1.732).
There is no solution.
2x-4=-9
Now, let's solve out some double inequalities. The procedure here is alike in some ways to solving single inequalities and still very different in other ways. As there are two ineq
-2(x-4)+3(2x-1)
Simpler method Let's begin by looking at the simpler method. This method will employ the following fact about exponential functions. If b x = b y then x
Solve following equations by factoring. a) x 2 - x = 12 b) y 2 + 12 y + 36 = 0 Solution a) x 2 - x = 12 First to solve it get everything on si
HOW TO FACTOR THE GIVEN
rename 1 3/4 as a fraction
f(x)=x^2+6x-38
(x2+6x+5)/(x-2)
