Answer:
The one that belong in the dividend bracket is the volume for A. The one that belongs in the divisor bracket is volume C.
Step-by-step explanation:
That's my explanation on what the answer is supposed to be.
Step-by-step explanation:
Let √x - 1/√x = a
Squaring both the sides,
x + 1/x - 2 = a^2
Putting the value,
3–2√2 + 1/(3–2√2) - 2 = a^2
a^2 = 1 - 2√2 + 1/(3–2√2)
= [(3–2√2) (1–2√2) + 1] / 3–2√2
= {3 - 8√2 + 9} / 3–2√2
= [12 - 8√2] / 3–2√2
Rationalising both the sides
= {(12 - 8√2)(3+2√2)} ÷ (9–8)
= 36 + 24√2 - 24√2 + 16(2)
= 36 - 32
=> 4
a^2 = 4
a = √4
a = 2, -2
So,
√x - 1/√x = a = 2, -2.
Number 2 is a constant rate of change
Answer:
x = -7
Step-by-step explanation:
-2x - 10 = 4
-2x = 14 | Add 10 to both sides
x = -7 | Divide both sides by -2
F(x)=3/x it’s 6x(7) now can I get thanks
