weeeeeb [17]

Answer:

The equivalent expression is:40(1.1699)^x

Hence, option c is correct.

Step-by-step explanation:

We have been given the function:

f(x)=40(1.04)^{4x}

Using:

x^{ny}=(x^n)^y

Here, n=4 and x=y

f(x)=40(1.04^4)^x

On simplification of 1.04^4=1.1698\approx1.1699 so we get:

40(1.1699)^x

Therefore, the equivalent expression is:40(1.1699)^x

Hence, option c is correct.

Answer:

  y -4 = 3(x +1)

Step-by-step explanation:

The point-slope form of the equation of a line with slope m passing through point (h, k) is ...

  y -k = m(x -h)

Your values for these parameters are ...

  m = 3

  (h, k) = (-1, 4)

Filling these into the form gives the equation you're looking for:

  y -4 = 3(x +1)
