Astudent taking a test consisting of 10 questions is told that
each questions after the first is worth 2 marks more than the
preceding question. if the third question of the test is worth 5 marks.
what is the maximum score that the student can obtain by attempting
8 questions?

96 points

Step-by-step explanation:

Because each question is worth more than the previous one, a student would obtain the highest score answering only 8 questions by skipping the first two and answering questions 3-10. Question 3 is worth 5 points and each question is worth 2 more points than the previous one, so if you got questions 3-10 right you'd get 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 96 points.

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)

the answer is d
