Answer:
f(x) = 8 - 1.5x
Step-by-step explanation:
Here, we want to write a function that can be used to describe the x th term of the sequence
Mathematically, this can be calculated by looking at the numbers in the sequence
The difference between each successive term
is -1.5 ( 6.5-8, 3.5 -5)
So the formula for then x th term will be;
f(x) = 8 - 1.5x
where x refers to the number of the term , for example the 4th term
First rewrite each number in scientific form
Lol this answer:
(3/4÷3/100-47/2)÷4/2.2/3+7/6
(3/4.100/3-47/2).2/4.2/3+7/6
(25-47/2).2/2.1/3+7/6
3/2.2/2.1/3+7/6
1/2+7/6

So we should first start off by checking for the ones with the same area, which is 72sq cm
80×90=7200sq cm so A is incorrect
8×10=80sq cm so B is incorrect
3×24=72sq cm so, so far C is correct
4×14=56sq cm so D is incorrect
And because all are incorrect except C
Then C is the correct answer, just to be sure, we will check the perimeter
24+24=48
48+3=51
51+3= 54
So the perimeter is different, making C the correct answer
