Function I’m just guessing?
Answer: -7
Form your equation. Let x be the number.
6x + 10 = 4x - 4
Solve.
6x + 10 = 4x - 4 Subtract 4x from both sides
2x + 10 = -4 Subtract 10 from both sides
2x = -14 Divide by 2 to both sides
x = -7 Answer!
Answer:
P_he = 562.5 mmHg
P_ne = 1068.75 mmHg
P_ar = 618.75 mmHg
Step-by-step explanation:
Formula for partial pressure is;
Partial pressure = mole fraction × total pressure
Mole fraction of Helium(He); x_he= 1/(1 + 1.9 + 1.1) = 1/4 = 0.25
Mole fraction of Neon(Ne); x_ne = 1.9/(1 + 1.9 + 1.1) = 1.9/4 = 0.475
Mole fraction of argon; x_ar = 1.1/(1 + 1.9 + 1.1) = 1.1/4 = 0.275
Thus;
Partial pressure of He;
P_he = 0.25 × 2250
P_he = 562.5 mmHg
Partial pressure of Ne;
P_ne = 0.475 × 2250
P_ne = 1068.75 mmHg
Partial pressure of Ar;
P_ar = 0.275 × 2250
P_ar = 618.75 mmHg
Answer:
A and B
Step-by-step explanation:
We are given that
Compare with it
Where vertex=(h,k)
We get
Vertex of g=(2,-1)
Vertex of f=(2,-4)
Equation of axis of symmetry=x-coordinate of vertex
Axis of symmetry of g
x=2
Axis of symmetry of f
x=2
Differentiate w.r.t x
f and g have both minima at x=2
Hence, option A and B are true.
