The answer is A) Right because the lengths 3 cm and 3 cm are obviously the same so it will form a right angle
Answer:
The correct answer is B) - 1/6
Step-by-step explanation:
To find the answer, simply subtract two consecutive values of f(x). Any 2 will give you the same answer.
49/6 - 25/3
49/6 - 50/6
-1/6
You should be able to multiply 91 by 8 to get the sum of the first 8 tests, then add the score on the 9th test. Then to get the average of the sum of the 9 tests you need to divide it by 9.
((91*8)+78)/9=89.555555555555.... So, 90%
