Answer: Question 1) No, because according to the law of exponents

x³.x³.x³ = x³⁺³⁺³ = x⁹

and x⁽³*³*³⁾ = x²⁷

Question 2) √x

Question 3) 4x

Question 4) ∛x²

Question 5) B = D

Step-by-step explanation:

Question 1) Is the expression x^3*x^3*x^3 equivalent to x^(3*3*3)? Why or why not? Explain your reasoning.

No, because according to the law of exponents

x³.x³.x³ = x³⁺³⁺³ = x⁹

and x⁽³*³*³⁾ = x²⁷

Question 2) Rewrite in simplest radical form 1/x^((-3)/6). Show each step of your process.

simplifying the denominator expoent: 1/x^((-3)/6) = 1/x^(-1/2)

apply the expoent to the hole fraction: 1/x^(-1/2) = (1/x)^(-1/2)

changing the signal on the expoent: (1/x)^(-1/2)  = (x)^(1/2)

changing the expoent into root: (x)^(1/2) = √x

1/x^((-3)/6) = 1/x^(-1/2) = (1/x)^(-1/2) = (x)^(1/2) = √x

Question 3) Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.

√x • 4√x = 4√x • √x = 4√x² = 4x

Question 4) Rewrite in simplest radical formx^(5/6)/x^(1/6). Show each step of your process.

x^⁽⁵/⁶⁾/x^⁽¹/₆⁾ = x^⁽⁵/⁶⁾ • 1/x^⁽¹/₆⁾ = x^⁽⁵/⁶⁾ • x^⁽⁻¹/₆⁾ = x^⁽⁵/⁶ ⁻ ¹/⁶) = x^⁽⁴/⁶⁾ = x^⁽²/₃⁾ = ∛x²

Question 5) Which of the following expressions are equivalent? Justify your reasoning.

A. ⁴√x³    B. 1/x⁻¹    C. ¹⁰√x⁵•x⁴•x²     D. x¹/³•x¹/³•x¹/³

A. ⁴√x³ = x³/⁴

B. 1/x⁻¹ = (1/x)⁻¹ = x

C. ¹⁰√x⁵•x⁴•x² = ¹⁰√x¹¹ = x¹¹/¹⁰

D. x¹/³•x¹/³•x¹/³ = x⁽¹/³⁺¹/³⁺¹/³⁾ = x³/³ = x

So, B = D

the volume v of a right circular cylinder of radius r and heigh h is V = pi r^2 h 1. how is dV/dt related to dr/dt if h is const
laiz [17]
In general, the volume

V=\pi r^2h

has total derivative

\dfrac{\mathrm dV}{\mathrm dt}=\pi\left(2rh\dfrac{\mathrm dr}{\mathrm dt}+r^2\dfrac{\mathrm dh}{\mathrm dt}\right)

If the cylinder's height is kept constant, then \dfrac{\mathrm dh}{\mathrm dt}=0 and we have

\dfrac{\mathrm dV}{\mathrm dt}=2\pi rh\dfrac{\mathrm dt}{\mathrm dt}

which is to say, \dfrac{\mathrm dV}{\mathrm dt} and \dfrac{\mathrm dr}{\mathrm dt} are directly proportional by a factor equivalent to the lateral surface area of the cylinder (2\pi r h).

Meanwhile, if the cylinder's radius is kept fixed, then

\dfrac{\mathrm dV}{\mathrm dt}=\pi r^2\dfrac{\mathrm dh}{\mathrm dt}

since \dfrac{\mathrm dr}{\mathrm dt}=0. In other words, \dfrac{\mathrm dV}{\mathrm dt} and \dfrac{\mathrm dh}{\mathrm dt} are directly proportional by a factor of the surface area of the cylinder's circular face (\pi r^2).

Finally, the general case (r and h not constant), you can see from the total derivative that \dfrac{\mathrm dV}{\mathrm dt} is affected by both \dfrac{\mathrm dh}{\mathrm dt} and \dfrac{\mathrm dr}{\mathrm dt} in combination.

Experimental probability question! I will give brainlist if you answer correctly, but I will give 5 stars and thanks even if you
Rom4ik [11]

Answer:

84% or 21/25

Step-by-step explanation:

1 is 8, 2 is 6, 3 is 9, 4 is 11, 5 is 9, 6 is 7. add the values: We get 50.  

because landing on 1 is an 8/50 chance, not landing on one is a 42/50 chance, which in turn is 84% or 21/25.
