An exponential function f(x)=a⋅bx passes through the points (0, 4) and (2, 64). What are the values of a and b?

Flura [38]

Answer:

a=b=4

Step-by-step explanation:

$f(x) = a\cdot b^x\\f(0) = a = 4\\f(2) = 4b^{2} = 64 \rightarrow b = 4\\ f(x) = 4 \cdot 4^x$

What is the seventh term of the geometric sequence with a first term of 729 and a common ratio of ?

SVEN [57.7K]

<u>Given</u>:

Given that the first term of the geometric sequence is 729.

The common ratio is $\frac{1}{3}$

We need to determine the seventh term of the sequence.

<u>Seventh term</u>:

The seventh term of the sequence can be determined using the formula,

$a_n=a_1(r)^{n-1}$

To find the seventh term, let us substitute n = 7 in the above formula, we get;

$a_7=a_1(r)^{6}$

Now, substituting $a_1= 729$ and $r=\frac{1}{3}$ , we get;

$a_7=729(\frac{1}{3})^{6}$

$a_7=729(\frac{1}{729})$

$a_7=1$

Thus, the seventh term of the geometric sequence is 1.

vovangra [49]

Answer:

150$

Step-by-step explanation:

In order to find the answer to this question you must find twenty-five percent of two-hundred.

50% of 100 = 50

100% of 100 = 100

100% of 200 = 200

50% of 200 = 100

25% of 200 = 150

= 150$

Hope this helps.
