Hopefully this is right! x
4a+3b=21 is open
Answer: A. (x - 4, y - 2)
B. (x + 7, y - 11)
<u>Step-by-step explanation:</u>
A) How do you get the x-coordinate of 3 to become a x-coordinate of -1? by subtracting 4 --> x - 4
How do you get the y-coordinate of 5 to become a y-coordinate of 3? by subtracting 2 --> y - 2
The transformation is: (x - 4, y - 2)
B) How do you get the x-coordinate of -4 to become an x-coordinate of 3? by adding 7 --> x + 7
How do you get the y-coordinate of 11 to become a y-coordinate of 0? by subtracting 11 --> y - 11
The transformation is: (x + 7, y - 11)
The total surface area of a regular tetrahedron is calculated through the equation,
SA = (sqrt 3) x a²
Substituting the known value,
SA = (sqrt 3) x (10 cm)² = 173.20 cm²
Its volume is obtained by,
V = ((sqrt 2)/ 12) x a³
V = ((sqrt 2) / 12) x (10 cm)³ = 117.85 cm³
Thus, its surface area and volume are 173.20 cm² and 117.85 cm³, respectively.
