Y varies inversely as the square of x. So we can write the relation between x and y as:

where k is a constant of proportionality. It is given that y = 7/4 when x = 1.
Using these values, we can write:

So, now the equation in terms of x and y can be written as:

We are to find y when x = 3. So we can write:
Thus, for x= 3 value of y will be 7/36
5.68x10^11
100=10^2
1 billion=10^9
10^2*10^9=10^11
Answer:
A
Step-by-step explanation:
RT=12
TU=5
RU=12+5=17
RS=17+7=24
SU=√(RS²-RU²)=√(24²-17²)=√(24-17)(24+17)=√(7×41)=√287
area=1/2×12×√287=6×√287≈101.6 unit²
Answer:
i think its A
Step-by-step explanation:
you add all the numbers up together and dvide by how many numbers there are. thats what i did and got 6
See you add 990 then diced by 54 and then you’ll get your answer
