Answer:
63
Step-by-step explanation:
To find the area of a trapezoid you have to use the formula
a+b/2 h
So we would substitute them
3 + 15 / 2 x 7
Which would equal
63
Hope this helps :)
In the figure ABCD is transformed to figure A'B'C'D'. It is Transformed from Quadrant 1 to quadrant 2 .That is point (x,y) is (-y,x) It is then moved up by 2 units.The figure ABCD is rotated counterclockwise and then translated up by 2 units to come to A'B'C'D'.
Option b Rotate 90 degrees counterclockwise then translate 2 units up is the right answer.
Answer: C) ΔUVW and ΔRST are congruent
Step-by-step explanation:
- Rigid motions move a geometric figure but do not change the size and shape of the figure.
- It produces congruent images.
There are four kinds of rigid transformation.
1) translation 2) reflection 3) rotation 4) glide reflection.
If a series of rigid motions maps ΔUVW onto ΔRST.
Then, ΔUVW and ΔRST must be congruent. (No change in size or shape)
hence, the correct statement is C) ΔUVW and ΔRST are congruent.
Try this explanation+solution:
1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.
Answer:
B is the answer that is incorrect and must be rejected.
Step-by-step explanation:
A trapezoidal shape need not have a line of symmetry to be a trapezoid.
