Very hungry from all from all of this shopping. The giant family purchased five appetizers for 1.9 x10^5 each. seven entrees for

9.2 x 10^5 each and three desserts for 9.8 x 10^4 each. If they paid with a 1.0x10^7, how much change would they recieve?

If an=24, which recursive formula could represent the sequence below? ...,24,88, 664, 8408A) An=(An-2)^2 + An-1 ; A1=2B) An= 3An

Rudik [331]

When we substitute $n = 4$ , we get...

$a_{n-3}=a_1\\ \\ a_{n-2}=a_2\\ \\ a_{n-1}=a_3\\ \\ a_n=a_4$

Comparing the given sequence: 24, 88, 664, 8408, we get

$a_{n-3}=a_1=24\\ \\ a_{n-2}=a_2=88\\ \\ a_{n-1}=a_3=664\\ \\ a_n=a_4=8408$

We need to substitute the above values in each option and check which is TRUE.

----

<u>Option A</u>

$a_n=(a_{n-2})^2+a_{n-1}, a_1=2\\ \\ a_n=(88)^2+664=7744+664\\\\a_n=8408 (TRUE)$

<u>Option B</u>

$a_n=3a_{n-1}+16\\ \\ a_n=3(664)+16\\\\a_n=2008 (FALSE)$

<u>Option C</u>

$a_n=(n)a_{n-1}-8\\ \\ a_4=(4)a_3-8=4(664)-8\\\\a_4=2648 (FALSE)$

<u>Option D</u>

$a_n=2a_{n-2}+7a_{n-1}\\ \\ a_n=2(88)+7(664)\\ \\ a_n=4824(FALSE)$

Conclusion:

Option A is the correct answer.

CalculatorIn the coordinate plane, what is the length of the line segment that connects points at (4, -1) and (9, 7)?Enter your

andre [41]

The formula to calculate the distance between two points is given by

$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

In this problem, we have the coordinates

(4, -1) and (9, 7)

substitute in the formula

$\begin{gathered} d=\sqrt{(7+1)^2+(9-4)^2} \\ d=\sqrt{8^2+5^2} \\ d=\sqrt{89} \\ d=9.43 \end{gathered}$ <h2>The answer is 9.43 units</h2>

-Is ZFDE a possible name for the figure below? Explain.<br> E<br> D<br> F<br> It’s number 14

gregori [183]

Answer: Yes $\angle FDE$ is one possible angle name

Another name is $\angle EDF$

When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.

This is why saying "angle FDE" is the same as "angle EDF".
