The constant of variation is 1.3 kg per m³
Step-by-step explanation:
Direct variation is when one variable is equal to a constant times
another variable, with no additions or subtractions alongside
If y is directly proportional with x, then
- y ∝ x
- y = k x, where k is the constant of variation
- The graph of the variation is a line passes through the origin
∵ The weight of air is directly proportional to its volume
∴ The weight (w) ∝ the volume (v)
∴ w = k v
∵ w = 13 kg
∵ v = 10 m³
- Substitute these values in the rule of variation above to find k
∴ 13 = k (10)
∴ 13 = 10 k
- Divide both sides by 10
∴ k = 1.3
The constant of variation is 1.3 kg per m³

Answer:
ahaha would love to help but can't see the photo :/
Step-by-step explanation:
Answer:
The answer would be 14.
Step-by-step explanation:
You need to SIMPLIFY. Make sure that you are solving the part of the problem that has parentheses then you can move on from there.
(Hope this helps!)
Answer:
<em>x² + 4y²+ 2x - 24y + 33 = 0
</em>
<em />
<em>= (x+1)² + 4(y-3)² - 1 - 36 + 33 = 0
</em>
<em>= (x+1)² + 4(y-3)² = 4</em>
<em />
<em>= (x + 1)²/2² + (y - 3)²/1² = 1</em>
<em></em>
<em>This is an Ellipse: C(-1,3)</em>
<em>The Standard Form of an Equation of an Ellipse is : </em><em>(x - h)²/a²/ (y - k)²/b² = 1</em>
<em></em>
<em>where Pt(h,k) is the center. </em><em>(a variable positioned to correspond with major axis)</em>
<em>a and b are the respective vertices distances from center</em>
<em>and√a² - b²are the foci distances from center: a > b</em>
Answer:
(A) 0 (B) f(x)≥3/2
