Hello!
The x and y are 'swapped. so we have
a reflection over the line y=x
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
Answer:
CA = 5
Step-by-step explanation:
Since the sides are 3 and 4, we recognize this as a 3:4:5 right triangle, with CA = 5. Using the Pythagorean theorem confirms this:
CA² = AB² +BC²
CA² = 3² +4² = 9 +16 = 25
CA = √25
CA = 5
Answer
C. y = 4x - 2
Explanation
Two equations of lines are said to be parallel if m₁ = m₂
m₁ is the slope of the given equation and m₂ is the slope second equation.
From the given equation,
y = 4x + 1
m₁ = 4
From the options, the only equation which is parallel to the given equation is
y = 4x - 2 because it slope, i.e m₂ = 4
The correct answer is Option C. y = 4x - 2
