Answer:

A=a+b

THIS IS THE FORMULA SO $\frac{A+B}{2H}$

A=3

B=8

H=2

SO = $\frac{3+8}{2}$

$\frac{10}{2}$

A ball is dropped from a height of 25feet and allowed to bounce until it comes to a rest. Each time the ball bounces it rebounds

alina1380 [7]

Answer:

$H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}$

Step-by-step explanation:

Given

$Initial\ Height =25$

$Rebound = \frac{4}{5}$

Required

Determine the height at the third rebound

At first rebound;

$H1 = 25 * \frac{4}{5}$

Second rebound

$H2 = 25 * \frac{4}{5}* \frac{4}{5}$

Third rebound

$H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}$

Hence; the equation is:

$H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}$

Solving further;

$H3 = 12.8\ ft$

Tema [17]

Answer:

14 and 16.

Step-by-step explanation:

We know that two consecutive even numbers is 30.

Let's let n be any number.

Then the first even number must be 2n.

This is because n can be any number, either even or odd. However, if we multiply it by 2, this ensures that 2n is even. Remember that any number multiplied by 2 yields an even number.

Therefore, the consecutive even number will be (2n+2). Not (2n+1), because that gives an odd number.

We know that they sum to 30. So, we can write the following equation.

$(2n)+(2n+2)=30$

And we solve from there:

$4n+2=30\\\Rightarrow4n=28\\\Rightarrow n=7$

So, the value of n is 7.

Therefore, the first even number is 7(2)=14.

And the consecutive even number is 16.

Complete the recursive formula of the geometric sequence 16\,,\,3.2\,,\,0.64\,,\,0.128,...16,3.2,0.64,0.128,

Nastasia [14]

Answer:

$a_{n+1}=0.2a_n$ for all n>0, $a_1=16$

Step-by-step explanation:

Let $\{a_n\}=\{16,3.2,0.64,0.128,\cdots \}$ be the sequence described.

A geometric sequence has the following property: there exists some r (the ratio of the sequence) such that $\frac{a_{n+1}}{a_n}=r$ forr all n>0.

To find r, note that

$\frac{3.2}{16}=\frac{32}{10(16)}=\frac{2}{10}=\frac{1}{5}=0.2$

Similarly

$\frac{0.64}{3.2}=\frac{64}{10(32)}=\frac{1}{5}=0.2$

$\frac{0.128}{0.64}=\frac{1}{5}=0.2$

Thus $a_{n+1}=r a_n=\frac{a_n}{5}=0.2a_n$ for all n>0, and $a_1=16$
