A = 7
B = 14
For A:
(7(sqrt)2)sin(45) = 7
7/sin(30) = 14
Answer:
When rotating any polygon 90 degrees, each vertice/point of the polygon should be changed from (x, y) to (y, -x). Because of this, E(-7, -4) should be E'(-4, 7), F(-2, -1) should be F'(-1, 2), and G(-5, -8) should be G'(-8, 5) after the rotation.
Step-by-step explanation:
Like I explained above, when rotating a shape 90 degrees <em>clockwise </em>on a plane, the points change from (x, y) to (y, -x). The student changed each point from (x, y) to (-y, x), which is a 90 degree <em>counterclockwise </em>rotation. That is why the student is incorrect.
I hoped this helped! Sorry, I am terrible at explaining things. :)
Answer:
199
Step-by-step explanation:
2004 is 24 years after 1980. The polynomial remainder theorem tells you the remainder from division by x-24 will be the function value c(24). We can find the remainder/function value by evaluating the function rewritten to Horner form:
c(x) = ((0.006x -0.48)x +12.8)x +85
c(24) = ((0.006(24) -0.48)(24) +12.8)(24) +85 = (-.336(24) +12.8)(24) +85
= 4.736(24) +85 = 198.664
c(24) ≈ 199
The approximate number of countries attending the 2004 Olympics was 199.
The correct answer is C. Two million seven thousand thirty and eighty-four thousandths.
Hope this helps :)
