Answer:
The sides are as follows:
Step-by-step explanation:
Starting with the side y, we can use the tan to solve for y:
The side x can be determined using sin:
So, the sides as as follows:
(you can also verify this result is correct using the Pythagorean theorem)
√44
2 Real Roots
<h2>Step-by-step explanation:</h2>Looking at the image attached, the discriminant is the value under the square root.
In the equation given:
a = 1
b = -8
c = 5
The discriminant is therefore:
√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44
√44 is a positive number. Because it is positive, there must be 2 real roots.
If it were negative, there would be 2 imaginary roots.
If it were zero, there would be 1 real root.
Step 1: Write out the equation
Step 2: Rewrite the equation
Step 3: Plot the graph of y = x² + 7x + 6
Step 4: Find the solution of the equation x² + 7x + 6 = 0
The solutions of x² + 7x + 6 = 0 are the x-coordinates of the points where the curve y = x² + 7x + 6 cuts the x-axis.
From the graph, we can see that the points are (-6, 0) and (-1, 0)
Hence, the solutions are -6, -1
