Data:
x y
16 4
32 16
48 36
Direct relation means that the ratio y / x is constant.
So, let's examine this ratio:
Ratio y / x
4/16 = 1/4
16/32 = 1/2
36/48 = 3/ 4
Given that the ratio y/x is not constant, the conclusion is that y does not vary directly with x.
Answer:
Option B - 2
Step-by-step explanation:
We have given, the length of a spring when it’s at rest is measured to be 0.56 centimeter.
We have to find, how many significant figures are there in this measurement?
Solution :
The rules to get the significant figure are
- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.
The given measurement is 0.56 cm.
It has two trailing zeros in the decimal i.e. 5 and 6.
There are only two significant figures.
Therefore, Option B is correct.

Answer:
47
Step-by-step explanation:
Evaluate the functions and find the required difference.
f(-2) = -(-2)^2 -7(-2) +4 = -4 +14 +4 = 14
g(6) = -5(6) -3 = -33
Then the difference is ...
f(-2) -g(6) = 14 -(-33) = 14 +33 = 47
