You did not write the question correctly but I will try to answer the question according to 2 possible interpretations of your question.

Case 1:

Given the geometric sequence:

4,\  \frac{4}{5} ,\  \frac{4}{25} ,\  \frac{4}{125} ,\ .\ .\ .

Common ratio is given by r= \frac{2nd\ term}{1st\ term} = \frac{ \frac{4}{5} }{4} = \frac{1}{5}

The explicit rule of a geometric sequence is given by T_n=ar^{n-1}

Therefore, the explicit rule of the given sequence is T_n=4\left( \frac{1}{5} \right)^{n-1}\ or\ 20\left( \frac{1}{5} \right)^n


Case 2:

Given the geometric sequence:

4,\ 4\cdot5,\ 4\cdot25,\ 4\cdot125,\ .\ .\ .

Common ratio is given by r= \frac{2nd\ term}{1st\ term} = \frac{4\cdot5}{4} = 5

The explicit rule of a geometric sequence is given by T_n=ar^{n-1}

Therefore, the explicit rule of the given sequence is T_n=4(5)^{n-1}\ or\ \frac{4}{5}(5)^n

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

M = 0.65146579

t=0

simplified = M ( t ) = 0.65146579 t

Functions f(x) and g(x) are shown below:
hoa [83]

f(x) is a multiple of the cosine function. g(x) is a multiple of the sine function. Both the cosine function and the sine function have a maximum value of 1, so the magnitude of the multiple will determine which function has the largest maximum value.

The multiple for f is 2; the multiple for g is 3, which is greater than 2. Hence g(x) has a larger maximum value than f(x).
