Please help on question 4.<br> (Questions 1, 2, and 3 have been answered.)

Answer:

Step-by-step explanation:

So, the longest tooth is 4 3/4 and the shortest is 3 1/4. So if you subtract 4 3/4 - 3 1/4, you will get the answer 1 2/4, which you can simplify to 1 1/2 or 1.5 :)

Answer:

$a_7=-15$

Step-by-step explanation:

$a_n$ is given as the nth term of a sequence.

We want to find $a_7$ , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for $a_n$ to find the value of the 7th term of the sequence.

We show this below:

$a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15$

So the 7th term is "-15"

An exponential function f(x)

natka813 [3]

Given:

An exponential function $f(x)=ab^x$ passes through the points (0, 12000) and (2, 3000).

To find:

The values of a and b.

Solution:

We have,

$f(x)=ab^x$ ...(i)

It passes through the point (0,12000). Putting x=0 and f(x)=12000 in (i), we get

$12000=ab^0$

$12000=a(1)$

$12000=a$

Given function passes through the point (2,3000). Putting x=2, a=12000 and f(x)=3000 in (i), we get

$3000=12000b^2$

$\dfrac{3000}{12000}=b^2$

$\dfrac{1}{4}=b^2$

Taking square root on both sides.

$\pm \dfrac{1}{2}=b$

For an exponential function b cannot be negative. So, $b=\dfrac{1}{2}$ .

Therefore, the value of a is 12000 and the value of b is $\dfrac{1}{2}$ .
