Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 = ( multiply both sides by 9 )
k = 135
y = ← equation of variation
Answer:
d = m / v.
Step-by-step explanation:
The density is a measure of the specific weight of a substance or object.
This is, the mass per unit of volume. Then, the average density is the ratio of the mass of a body to the volume it occupies in space:
The equation for density is:
being m the total mass in the volume, and V the volume.
2 and 11/100. I think that's as simple as it gets in a mixed number form
Answer:
f(x) = 2x(x - 8)
f(x) = 2(x - 2)² - 8
Step-by-step explanation:
Let the equation of the quadratic function is,
f(x) = a(x - h)² + k
Here, (h, k) is the vertex of the function.
From the graph attached,
Vertex of the parabola → (2, -8)
Therefore, equation of the function will be,
f(x) = a(x - 2)² - 8
Since, the graph passes through origin (0, 0),
f(0) = a(0 - 2)² - 8
0 = 4a - 8
a = 2
Equation of the given parabola will be,
f(x) = 2(x - 2)² - 8
= 2(x² - 4x + 4) - 8
= 2x² - 8x + 8 - 8
= 2x² - 8x
= 2x(x - 8)
Therefore, factored form of the function will be,
f(x) = 2x(x - 8)
