Enter the explicit rule for the geometric sequence ...
60, 12, 12/5, 12/25, 12/125
Answer:
an = 60 x 1/5^n-1
Step-by-step explanation:
correct me if i am wrong, but I just learned about this stuff so hopefully this helps. The explicit rule/formula is an = a1 x r^n-1. In this formula, a1 is the first term (60), and r is the common ratio (1/5). Now all that is left to do is to write the equation which would be 60 x 1/5^n-1.

Step-by-step explanation:
The line which 3x represents is twice as big as the 48. That's because both sides other than the base are bisected.
3x = 2 * 48
3x = 96 Divide by 3

×-2+2×+4+2×-2=180 what does x equal in this equation.
Answer:
x = 36
Here's how I got that:
- Group like terms -
x - 2 + 2x + 4 + 2x - 2 = 180
↓
5x - 2 + 4 - 2 = 180
↓
5x = 180
- Divide both sides by 5 -
5x/5 = 180/5
↓
x = 36

Given polynomial:
x¹⁹ + x¹⁷ + x¹³ + x⁷ + x⁵ + x³Group as follows:
(x¹⁹ + x¹⁷) + (x¹³ + x¹¹) + (x⁷ + x⁵) + (x³ + x) - x = x¹⁷(x² + 1) + x¹¹(x² + 1) + x¹⁵(x² + 1) + x(x² + 1) - xAs we see all terms have (x² + 1) as factor apart from the last one.
It means the remainder is - x

4. Jeremy is starting a juice-bar business. The cost to start the business is $32,000 and the
monthly costs are $4,000. He has been earning $5,600 every month in revenue. In how many
months will Jeremy's business break-even and earn a profit?
Answer:
Step-by-step explanation: Ok so the important thing is to figure out how much he makes each month. if he earns 5,600 but the cost are 4,000 he makes 1,600 every month. To figure out how many months it will take we divide 32,000 by 1,600 to get 20. that is when he breaks even, 20 months. To make a profit it will be 21 months.

A town’s population increased from 25200 to 26460. Find the percent of increase.
Answer:
5%
Step-by-step explanation:
Based on the given conditions, formulate: (26460-25200)÷25200
Calculate the sum or difference: 1260/25200
Cross out the common factor: 1/20
Multiply a number to both the numerator and the denominator: 1/20 * 5/5
Write as a single fraction: 5/20*5
Calculate the product or quotient: 5/100
Rewrite a fraction with denominator equals 100 to a percentage: 5%

Greg is recording the changes in his bank account balance. In the morning, he records a deposit of $7. In the afternoon, he records a purchase of
$8
Create two expressions that each represent the total change in Greg's bank account balance after his deposit and purchase. Move numbers
to the lines to create the expressions.
Expression a: _-_
Expression b: _-_
Choices -8, -7, 7, 8
Answer:
Step-by-step explanation:
i think that it is either -7 - -8 or -7 + 8 or -7+-8.
Two expressions that each represent the total change in Greg's bank account balance after his deposit and purchase are
Expression a = 7 - 8
Expression b = -8 - (-7)
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.
For example, x + y is an expression, where x and y are terms having an addition operator in between.
Given,
Greg records deposit of $7
He records purchase of $8 b
Total change = 7 + (-8)
Expression a = 7 - 8
Expression b = -8 - (-7)
Hence, 7 - 8 and -8 - (-7) are the two expressions for total change in Greg's bank account after his deposit and purchase.

Kimi and Jordan are each working during the summer to earn money in addition to
their weekly allowance, and they are saving all of their money. Kimi earns $9 per hour
at her job, and her allowance is $8 each week. Jordan earns $7 per hour, and his
allowance is $16 each week.
Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
Kimi
Earnings = $9 per hourWeekly allowance = $8So, the equation for Kimi's weekly earning is:
[tex]y =9x + 8[/tex]
Jordan
Earnings = $7 per hourWeekly allowance = $16So, the equation for Jordan's weekly earning is:
[tex]y = 7x + 16[/tex]
Equate both equations
[tex]7x + 16 = 9x + 8[/tex]
Collect like terms
[tex]9x - 7x = 16 - 8[/tex]
[tex]2x =8[/tex]
Divide both sides by 2
[tex]x =4[/tex]
Hence, their earnings would be the same after 4 hours

Alisha has a five–year car loan of $15,000 with an interest rate of 6 percent. If the interest is compounded annually, how much will she pay in total for her car?
Answer:
$20,073.38
Step-by-step explanation: Step 1: Find the percentage. The formula for annual compound interest is A = P(1 + r)^t, where A = amount (total amount), P = principal (initial amount), r = rate (percentage), and t = time (in years). Our rate is 6%, which is 0.06 in decimal form. Add it to 1. 1 + 0.06 is 1.06.
Step 2: Raise 1.06 to the 5th power. Because we are finding the amount in 5 years, we do that step. 1.06^5 is 1.3382255776.
Step 3: Do not delete the decimal from the calculator. Multiply it by 15,000 to find the total amount. When you do, you get 20,073.383664 or 20,073.38 when rounded to the nearest hundredth.
