Answer:

n = 16

Step-by-step explanation:

Given the expression;

$log_2 n = 4$

If $log_a b = c, then;\\a^c = b$

Applying this to the question;

2⁴⁴= n

16 = n

Swap'

n = 16

Hence the value of n is 16

Identify the algebraic description that maps a point (3, 7) onto another point (-5, 7).

ella [17]

Answer:

A) (x, y) → (x - 8, y)

Step-by-step explanation:

(3, 7) → (-5, 7)

Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.

A) (x, y) → (x - 8, y)

(3, 7) → (3 - 8, y)

(3, 7) → (-5, 7)

This matches our problem, and therefore, A is the correct answer.

Hope this helps!

For the given functions, (a) express dw/dt as a function of t, both by using the chain rule and by expressing w in terms of t an

ch4aika [34]

By the chain rule,

$\dfrac{\mathrm dw}{\mathrm dt}=\dfrac{\partial w}{\partial x}\dfrac{\mathrm dx}{\mathrm dt}+\dfrac{\partial w}{\partial y}\dfrac{\mathrm dy}{\mathrm dt}+\dfrac{\partial w}{\partial z}\dfrac{\mathrm dz}{\mathrm dt}$

We have

$w=7ye^x-\ln z\implies\begin{cases}\dfrac{\partial w}{\partial x}=7ye^x\\\\\dfrac{\partial w}{\partial y}=7e^x\\\\\dfrac{\partial w}{\partial z}=-\dfrac1z\end{cases}$

and

$\begin{cases}x=\ln(t^2+1)\\y=\tan^{-1}t\\z=e^t\end{cases}\implies\begin{cases}\dfrac{\mathrm dx}{\mathrm dt}=\dfrac{2t}{t^2+1}\\\\\dfrac{\mathrm dy}{\mathrm dt}=\dfrac1{t^2+1}\\\\\dfrac{\mathrm dz}{\mathrm dt}=e^t\end{cases}$
