The qualities of the set {(x,y): x>0,y>0} is as under:
- All points lie in first quadrant.
- All values are positive and greater than zero.
Given a set {(x,y),x>0,y>0}.
We are required to determine the qualities of the set.
We know that a set is a collection of things,numbers, fractions, etc.
In any set the values of x represents the domain of the function and the values of y represents the value of codomain of the function with which the set belongs to.
Set={(x,y): x>0,y>0}
From the above set we can find the qualities stated below:
- All points lie in first quadrant as the first quadrant only contains positive values of x and y.
- All values are positive because it is given that they are greater than zero
Hence the qualities of the set {(x,y): x>0,y>0} are that all values should be in first quadrant and all the values are positive.

Answer:a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).
Step-by-step explanation:
Answer: <span>If x – 5 ≠ 10, then 4x + 1 ≠ 61
Justification:
</span>
1) The inverse of a conditional is negating both the hipothesis and the conclusion of the conditional, keeping the same sense of the implication.
2) This is the scheme (the symbol ~ is used to negate)
conditional: p → q
hypothesis: p
conclusion: q
negated hypothesis: ~p
negated conclusion: ~ q
inverse conditional: ~p → ~q
3) So, for the hypotheis <span>p: x – 5 =10 and the conclusion q: 4x + 1 = 61, the conditional p→ q is:
if x - 5 = 10 then 4x + 1 = 61.
And the inverse is negating both the x - 5 = 10 and 4x + 1 = 61, leading to:
If x – 5 ≠ 10, then 4x + 1 ≠ 61, which is the answer.</span>
Answer:
2 and 3
Step-by-step explanation:
2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio
3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
The ratio of the perimeters is the same as the scale factor.
scale 1:4
Answer:
0.025 Kg/ cm²
Step-by-step explanation:
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion :
where b = constant of proportionality
to determine the answer in this question :
1. determine constant of proportionality
200 = k / 32
k = 6400
2. Determine the amount of pressure using the constant of proportionality
256, 000 = 6400 / pressure
pressure = 6400 / 256, 000 = 0.025
