Answer:
Option 3
Step-by-step explanation:
If (x, y) is on h(x), then (y, x) is on the inverse.
Thus, if (4, 2) is on the inverse, then (2, 4) must be on the original. (Which it is not, so this option is incorrect)
If (0, 1/2) is on the inverse, then (1/2, 0) must be on the original. (It is not, so this option is also incorrect)
If (0, 1) is on the inverse, then (1, 0) must be on the original. (It is not, so this option is also incorrect)
If (-5, 1) is on the inverse, then (1, -5) must be on the original. (It is not, so this option is incorrect)
The correct answer would be the third option.
True!
all parabolas with vertical directrix DO open to the left/right.
Answer:
x=88, so it is acute.
Step-by-step explanation:
The two known angles are 45 degrees and 47 degrees. We know that in a triangle, the three angles always add up to 180 degrees.
This means that the third angle is 180-(45+47), or 180-92, or 88. So, the third angle is 88 degrees.
Acute triangles are when all the angles are less than 90. Right is when one angle is exactly 90. Obtuse is when one is more than 90. 88, 45, and 47 are all less than 90, so it is an acute triangle.
