a loan payment of $1000 was due 60 days ago and another payment of $1200 is due in 30 days. what's the single payment 90 days from now is required to pay off the two obligations if interest is to be 12% and agreed focal date is on 90 days from now?
The single payment required 90 days from now to pay off the two obligations, including interest, is approximately $2230.41.
To calculate the single payment required to pay off the two obligations, we need to consider the interest accrued over the specified time period.
Let's break down the problem into two parts:
1. Loan payment of $1000 due 60 days ago:
This payment has already accrued interest for 60 days. To calculate the total amount owed, we need to calculate the interest accrued. The formula to calculate simple interest is:
Interest = Principal * Rate * Time
Here, the principal amount is $1000, the interest rate is 12% (0.12 as a decimal), and the time is 60/365 years (since we're assuming a 365-day year). Using these values, we can calculate the interest accrued as:
Interest1 = $1000 * 0.12 * (60/365)
2. Loan payment of $1200 due in 30 days:
This payment will accrue interest for the remaining 30 days until the agreed focal date, which is 90 days from now. Using the same formula, we can calculate the interest accrued as:
Interest2 = $1200 * 0.12 * (30/365)
To find the total amount required to pay off the two obligations, we sum the principal amounts and the accrued interest:
Total payment = $1000 + Interest1 + $1200 + Interest2
Now, let's calculate the values:
Interest1 = $1000 * 0.12 * (60/365) = $19.18 (approx.)
Interest2 = $1200 * 0.12 * (30/365) = $11.23 (approx.)
Total payment = $1000 + $19.18 + $1200 + $11.23 = $2230.41 (approx.)
Therefore, the single payment required 90 days from now to pay off the two obligations, including interest, is approximately $2230.41.

Find the midpoint of the line segment joining points A and B A(2,-5); B(6,1)
Answer:
The answer is ( 4 , - 2)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} ) \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(2,-5); B(6,1)
So we have
[tex]M = ( \frac{2 + 6}{2} \: , \: \frac{ - 5 + 1}{2} ) \\ = ( \frac{8}{2} \: , \: - \frac{4}{2} )[/tex]

f(x)
Answer: x
Step-by-step explanation:
The inverse undos any changes to x, reversing those changes will leave x. Ex: f(x)=x+2. The inverse (from replacing x with y and y with x and solving for y) is h(x)=x-2. Plugging x+2 into h(x) (composition of functions) results in x. 2 and -2 cancel out.

The perimeter of a parallelogram is 56 meters. The width of the parallelogram is 8 meters less than its length. Find the length and the width of the parallelogram.
Answer:
Width is 10
Length is 18
Step-by-step explanation:
Perimeter is calculated as 2(w+l) or w+w+l+l. When you put those two numbers into the equation 2(10+18) or 10+10+18+18, you get the exact same answer of 56, and since 10 is eight less than 18, it would be the width.
Answer:
Length L = 18 m Width W = 10 m
Step-by-step explanation:
perimeter P = 2L + 2W
where
Perimeter P = 56 m
Width W = L - 8 m
find:
length L
width W
solution:
just plugin the values into the formula:
P = 2L + 2W
56 = 2L + 2(L - 8)
56 = 2L + 2L - 16
56 + 16 = 4L
L = 72/4
L = 18 m
solve for W:
substitute L=18 back into the equation W=L-8
W = 18 - 8
W = 10 m
therefore:
length L = 18 m
Width W = 10 m
proof:
56 = 2(18) + 2(10)
56 = 36 + 20
56 = 56 ----- OK

10/ an instant lottery game gives you probability 0.08 of winning in any one play. plays are independent of each other. a. if you play 5 times, what is the probability that you win on none of your plays? b. what is the probability that you win 3 or more of your 5 plays of this game?
a. The probability that you win on none of your 5 plays is approximately 0.6634. b. The probability that you win 3 or more of your 5 plays of this game is approximately 0.004497.
To solve these problems, we'll use the binomial probability formula.
a. The probability of winning in any one play is 0.08, so the probability of losing in any one play is 1 - 0.08 = 0.92.
The probability of winning on none of your 5 plays can be calculated as the probability of losing on each play, which is 0.92, raised to the power of the number of plays.
P(losing all 5 plays) = (0.92)^5 = 0.6634 (rounded to four decimal places)
Therefore, the probability that you win on none of your 5 plays is approximately 0.6634.
b. To find the probability of winning 3 or more of your 5 plays, we need to calculate the probability of winning 3, 4, or 5 plays and sum them up.
P(winning 3 or more plays) = P(winning 3 plays) + P(winning 4 plays) + P(winning all 5 plays)
P(winning 3 plays) = C(5, 3) *[tex](0.08)^3 * (0.92)^2[/tex]
= 10 * 0.000512 * 0.8464
≈ 0.00434 (rounded to five decimal places)
P(winning 4 plays) = [tex]C(5, 4) * (0.08)^4 * (0.92)^1[/tex]
= 5 * 0.000032768 * 0.92
≈ 0.000151 (rounded to six decimal places)
P(winning all 5 plays) = [tex](0.08)^5[/tex]
≈ 0.000006 (rounded to six decimal places)
Now we can sum up these probabilities:
P(winning 3 or more plays) ≈ 0.00434 + 0.000151 + 0.000006
≈ 0.004497 (rounded to six decimal places)
Therefore, the probability that you win 3 or more of your 5 plays of this game is approximately 0.004497.

Step 2: Solve for x
Distribute: 3x - 12 = 5 + 3x + 3Combine like terms: 3x - 12 = 3x + 8Subtract 3x on both sides: -12 ≠ 8Here, we see that x has to equal no solution. No value of x would make the equation true.
Answer:
no solutions
Step-by-step explanation:

The cost of a movie ticket is $20, and the cost is predicted to increase by 2% each year over the next 10 years. Find the cost of a ticket after 10 years.
Answer: $24.38
Step-by-step explanation:
So since the cost of a movie ticket is $20 and the cost is predicted to increase by 2% each year over the next 10 years. to find the cost after 10 years you want to solve for x.
so x=20(1.02)^10
20 is the initial cost and 0.02 is the rate of growth. expressed as a decimal number, the base is b=1+0.02=1.02 and the exponent 10 is the number of years
