The nth term of a geometric sequence is given as:
[tex]a_n=ar^{n-1}\\\\where\ a=first\ term,a_n=nth\ term, r=common\ ratio=\frac{a_n}{a_{n-1}}[/tex]
9)
a = -4, r = 12 / -4 = -3
10)
a = -2, r = -8 / -2 = 4
[tex]a_{8}=-2*(4)^{8-1}=-2*(4)^{7}=-32768[/tex]
11)
a = -1, r = -5
[tex]a_{9}=-1*(-5)^{9-1}=-1*(-5)^{8}=-390625[/tex]
12)
a = -1, r = -2
[tex]a_{12}=-1*(-2)^{12-1}=-1*(-2)^{11}=2048[/tex]

Kiran scored 223 fewer points in a computer game than Tyler. Kiran scored 409 points. Which equation would Kiran use to determine how many points, t, Tyler scored?
Answer:
The equation is:
[tex]409 = T - 223[/tex]
And the solution is:
[tex]T = 632[/tex]
Step-by-step explanation:
Given
Represent Kiran with K and Tyler with T
Kiran score is represented as:
[tex]K = 409[/tex]
Also, Kiran scored 223 less than Tyler.
This is represented as:
[tex]K = T - 223[/tex]
Substitute 409 for K
[tex]409 = T - 223[/tex]
Make T the subject
[tex]T = 409 +223[/tex]
[tex]T = 632[/tex]

Convert 6/7 to a decimal. Round to the nearest hundreths.
Answer:
Step-by-step explanation:
6/7 = 0.8571428571 = 0.86
The fraction 6/7 value in decimal form is 0.86.
To convert the fraction 6/7 to a decimal, you need to divide the numerator (6) by the denominator (7). Here's how you can do it:
Divide 6 by 7: 6 ÷ 7
= 0.8571428571428571 (long division)
To round the decimal to the nearest hundredths, look at the digit in the thousandths place (the third digit after the decimal point).
In this case, the digit is 7.
Since the digit 7 is greater than or equal to 5, we round up the hundredths digit.
The hundredths digit is the second digit after the decimal point.
The rounded decimal is 0.86 (rounded to two decimal places).

4. 1/243=0.004
Answer:
1.4/9
2. 9/25
3. 1/256
4. 1/243
Step-by-step explanation:
1. (2/3)^2= (2/3)*(2/3)=4/9
2/3=0.6667 raised to the power 2 is 4 over 9
2. (3/5)^2=(3/5)*(3/5)=9/25
3/5=0.6 raised to power 2 is 9 over 25
3. (1/4)^4=(1/4)*(1/4)*(1/4)*(1/4)=1/256
1/4=0.25 raised to the power 4 is 1 over 256
4. (1/3)^5=(1/3)*(1/3)*(1/3)*(1/3)*(1/3)=1/243
1/3=0.333 raised to the power 5 is 1 over 243
Amanda is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges an initial fee of $55 and an additional 70 cents for every mile driven.
Company B charges an initial fee of $97.50 and an additional 20 cents for every mile driven.
For what mileages will Company A charge less than Company B?
Write your answer as an inequality, using m for the number of miles driven.
Answer:
The mileages for which Company A charges less than Company B is 0 miles ≤ m ≤ 85 miles
Step-by-step explanation:
The given parameters for the two companies are;
For Company A
Company A initial fee = $55
The additional fee per mile = 70 cents
For Company B
Company B initial fee = $97.50
The additional fee per mile = 20 cents
Let [tex]C_A[/tex] represent the total charge for company A and let [tex]C_B[/tex] represent the total charge for company B, we have;
[tex]C_A[/tex] = 55 + 0.70 × m
[tex]C_B[/tex] = 97.50 + 0.20 × m
Where "m" represents the number of miles driven
Therefore, the cost of Company A and Company B are the same or equal when have the following relation;
[tex]C_A[/tex] = [tex]C_B[/tex]
∴ 55 + 0.70 × m = 97.50 + 0.20 × m
0.70 × m - 0.20 × m = 97.50 - 55
0.5 × m = 42.5
m = 85
The number of miles driven for which the two companies will charge the same amount, m = 85 miles
Therefore, given that the initial fee for Company A is less than the initial fee for Company B. we have;
Therefore for 0 miles ≤ m < 85 miles, Company A charges less than Company B.

Mr. Lozano's office has nine rows of filing cabinets with nine cabinets in each row. Mrs. Jackson's office has six rows of cabinets with 12 cabinets in each row. How many more cabinets does Mr. Lozano have than Mrs. Jackson?
Answer:
Mr. Lozano has 9 cabinets more.
Step-by-step explanation:
Mr. Lozano's office has nine rows of filing cabinets with nine cabinets in each row.
So, the total cabinet in Mr. Lozano's office is: [tex]9 \times 9=81[/tex]
Thus, the total number of cabinets in Mr. Lozano's office is 81.
Mrs. Jackson's office has six rows of cabinets with 12 cabinets in each row.
So, the total cabinet in Mrs. Jackson'soffice is: [tex]6 \times 12=72[/tex]
Thus, the total number of cabinets in Mrs. Jackson's office is 72.
Now subtract 72 from 81 as Mr. Lozano's office has more cabinets.
[tex]81-72=9[/tex]
Hence, Mr. Lozano has 9 cabinets more.

solve for x???????????
Answer:
[tex]x=9[/tex]
Step-by-step explanation:
For this you just have to make an equation and in order to do that you have to know that all these angles will equal 180°. Now we can write it out.
[tex]3x-4+13x+2+5x-7=180[/tex]
Now we combine like terms:
[tex]21x-9=180[/tex]
Add the 9 on both sides:
[tex]21x=189[/tex]
Divide the 21 on both sides:
[tex]x=9[/tex]
