C and d
when x = 2 , f(x) = x^2 = 4
and
when x = 1 f(x) = 5
Step-by-step explanation:
<u>According to given table we have pairs of points:</u>
- (4, 6.00), (5, 8.25), (6, 10.50)
<u>The rate of change is:</u>
- (8.25 - 6.00)/(5 - 4) = 2.25
or
- (10.50 - 8.25)/(6 - 5) = 2.25
<u>It is 2.25 and the meaning is:</u>
Answer:
8cm and 9cm
Step-by-step explanation:
8cm and 9cm would be the two possible lengths for the triangle because for the triangle to work you need the other two other sides when added together needs to be greater then 13. Furthermore 5 + 8 = 13 and as 13 is the same length as the one side that is given, a triangle couldn't possibly be formed as it would just be a straight line. Moreover, this is the same with 6 + 7 which is also 13. 7 + 2 is 9 and because 9<13 a triangle couldn't possibly be formed. Finally, 8 + 9 which equals to 17 are the only two possible lengths for the triangle as 17 > 12.
Number one is A. Two is D and I think three is A ( I'm not entirely sure about the last one)
