Answer:
Step-by-step explanation:
step 1
Find the diameter of the circle
the formula to calculate the distance between two points is equal to
substitute the values
The radius is half the diameter
so
step 2
Find the center of the circle
the center of the circle is the midpoint between the endpoints of the diameter
so
The center is
step 3
Find the equation of the circle
The equation of the circle is
substitute the values
Answer:
Reflecting a point across the y-axis -> changes the sign of the x-coordinate
Reflecting a point across both axes -> changes the sign of both coordinates
Reflecting a point across the x-axis -> changes the sign of the y-coordinate
Step-by-step explanation:
Reflections:
- The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
- Reflecting a point across both axes is the same thing as rotating it 180 degrees, so the rule is (-x, -y). This means that both coordinates' signs change.
- Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.
Triangle RST was dilated by a scale factor of 1/2
Given: triangle R'S'T', is an isosceles triangle, with each leg measuring 8 units.
Pre-image:
measure of pre-image * scale factor = measure of resulting image
measure of pre-image = measure of resulting image / scale factor
measure of pre-image = 8 / 1/2
measure of pre-image = 8 * 2/1
measure of pre-image = 16 units.
