Answer
25 square
centimeters
Step-by-step explanation:
We want to find the area of the image of a rectangle with an area of 25 square
centimeters that has been rotated and reflected in
the coordinate plane.
Recall that, rotation and reflection are rigid transformations.
This means that, the preimage and the image rectangle are congruent.
Therefore the area of the image rectangle is still 25 square centimeters
Answer:
x = √30
Step-by-step explanation:
For an equilateral triangle, the measure of the angle at each vertex is 60 degrees
Thus, the angle 60 faces the side measure x
Also, the given length is adjacent to the angle 60 measure
Mathematically, the trigonometric ratio that links the adjacent and the opposite is the tan
The tan is the ratio of the opposite to the adjacent
Thus;
Tan 60 = x/ root 10
x = root 10 * tan 60
x √(10 * √(3
x = √30
Answer:
slope intercept: y=5x-7
Step-by-step explanation:
first you need slope: y2-y1/x2-x1
-12-3/-1-2=
-15/-3=
5
then plug into this formula: y-y1=m(x-x1)
y-3=5(x-2)
y-3=5x-10
y=5x-7
