The laws of sines is already indicated in the provided images.
1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,
sin20/3.3 = sin(126)/b
b = 7.8 units
From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.
2. Angle J = 180 - 120 - 40 = 20 degrees. Then,
sin(20)/2 = sin(120)/k
k = 5.1 units</span>
According to the graph, <em>g</em> (-4) = 1, so <em>g</em> ⁻¹(1) = -4.
Answer: 1350 miles
Step-by-step explanation:
Given that one inch is 450 miles. We can use a proportion to solve for miles at 3 inches.
x=450*3=1350 mi

Answer: the fraction -1/11</h3>
How to get this answer:
Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (14 - 9)/(-32 - 23)
m = (5)/(-55)
m = -1/11
The negative slope means the line goes downhill as you read it from left to right.
Answer:
For (fg)(x)
(fg) (x) = 4x^4 - 8x^3 -11x^2 -3x
With no restrictions on the x
Step-by-step explanation:
To find (fg) (x) = f(x) . g(x)
We need to multiply f(x) with g(x)
(fg) (x) = (2x^2 -5x -3) * (2x^2 + x)
fg(x) = 4x^4 + 2x^3 - 10x^3 - 5x^2 -6x^2 -3x
fg(x) = 4x^4 - 8x^3 -11x^2 -3x
