The sum a = 4966.7 is invested at a rate of r = 4.439% for a period of t=4.621 years.
What exactly is a continuous compounding formula?The continuous compounding formula should be used when an issue expressly states that the amount is "constantly compounded."This formula makes use of the mathematical constant "e," which has a value of approximately 2.7182818.The continuous compounding formula is as follows:
A = Pe^rtWhere P represents the starting sum, A represents the total sum, r represents the interest rate, t represents time, and e is a mathematical constant.So,
According to the first point, we know that atr = 0.02, and t = 1.
a(e^rt) - a(1+r)^t = a[ e^(0.02) - 1.02]= 0.00020134 aThus for advantage > 1$ we need is as follows:
0.00020134 a > 1a > 1/ 0.00020134a~4966.7According to the second point, we got that:
t1= 1, a= 1000Then,
1000[e^r-1-r]> 1>> e^r-1-r > 0.001>>e^r-1-r - 0.001 > 0 ......(1)Now we hold that r > 0.04439:
r~ 0.04439 r~ 4.439%According to the third point, we got to know that:
a = 1000, r = 0.02,1000[e^0.02t - (1.02)^t] > 1>>e^0.02t - (1.02)^t > 1 ......(2)Now 2nd equation holds t > 4.621.
Therefore, the sum a = 4966.7 is invested at a rate of r = 4.439% for a period of t=4.621 years.

(please help) a couple with 32 children want to save for college. They invest 50,000 in two different corporate bonds for 1 year One bond pays 5% simple interest while the other pays 6.5% simple interest. The total interest they received from the bonds was $3000. Find the amount they invested in each bond
The amount invested in the bond with 5% simple interest is $16,666.67
The amount invested in the bond with 6.5% simple interest is $33,333.33
What is simple interest?
The interest earned under a simple interest arrangement is determined as the amount invested multiplied by the interest rate and the time the investment lasts
I=PRT
let us assume that x was invested in the bond with 5%
interest on x=5%*x=0.05x
amount invested in other bond=50000-x
interest earned on 6.5%=(50000-x)*6.5%
interest earned on 6.5%=3250-0.065x
total interest=0.05x+3250-0.065x
total interest=3250-0.015x
total interest=3000
3000=3250-0.015x
0.015x=3250-3000
0.015x=250
x=250/0.015

Since slopes m₁ and m₂ are equal to 5, it shows that these two lines are parallel.
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
The condition for two parallel lines.In Geometry, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:
m₁ = m₂
Note: m is the slope.
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + b
Given the following equations:
y = 5x + 1
2y - 10x + 3 = 0 ⇒ y = 5x - 3/2
m₁ = m₂ = 5.

Two towns are 7cm apart on the map
Work out the actual distance between the towns. Give your answer in kilometres
Answer:
Step-by-step explanation:
1: 500,000 cm
500,000cm can also be written as 5000m or 5 km
So it becomes 1:5km
the 1 represents 1cm on the map so every centimeter in the map is 5 kilometers in real life
If we want to get what 7 cm would be in kilometers then we have to multiply both sides by 7.
So it would be 1 x 7 and 5x 7
it would end up being 7 : 35 km

2.4645×10⁴ gallons of milk do United States dairy cows produce each year.
Why we need scientific notation ?We need scientific notation reason is large number can be written in compact form.
According to the given question There are approximately 9.3 x 106 dairy cows in the United States.
Which is 985.8 cows in the united states.
Also given each cow produces 2.5×10 = 25 gallons of milk per year.
∴ United state cows will produce (985.8×25) gallons of milk each year which is = 24645 gallons of milk per year.
Now 24645 can be represented as 2.4645×10⁴ gallons of milk.
We have raised it to the 4th power of 10 because we have moved the decimal 4 digits before to balance the number and we know that in scientific notation base should be greater than 1 and less than 4 so moving the decimal to some other place is not valid.

I am a 5-digit number between 52,000 and 53,000. The sum of my digits is 21. My ones digit is a multiple of 3. My tens digit is equal to my hundreds digit.
Read the clues. Find the number
Step-by-step explanation:
5 digit number
5abcd
a = 2 or a = 3. but a = 3 means the upper limit of 53,000. and the sum of digits is 8 and not 21.
so, a = 2.
d = 3n
c = b
5 + a + b + c + d = 21
5 + a + 2b + 3n = 21
a + 2b + 3n = 16
2 + 2b + 3n = 16
2b + 3n = 14
so, n must be an even number to allow an even result (14). therefore, n = 0 or n = 2 (any larger even number n like 4 would not create a single digit result)
if n = 0, then 2b = 14, b = 7
if n = 2, then 2b + 6 = 14, 2b = 8, b = 4
so, we have the options

what is the distance (2,-2) and (-3,-1) points
The distance between two points (2,-2) and (-3,-1) is √26 units.
Given points are (2,-2) and (-3,-1)
Let A(2,-2), B(-3,-1)
We need to calculate the distance between two points.
We know that distance between two points means the length of the line segment that connects two points in the 2D plane.
The formula for finding the distance between the two points A(x₁, y₁),
B(x₂, y₂) in a plane is given by
D = √((x₂ - x₁)² + (y₂ - y₁)²)
Now we have two points A(2,-2), B(-3,-1)
By using the above formula we get the distance as
D = √((-3 - 2)² + (-1 - (-2))²)
D = √((-5)² + (-1+2)²)
D = √(25 + (1)²
D = √(25+1)
D = √26 units

A person invests 9000 dollars in a bank. The bank pays 4.25% interest compounded
semi-annually. To the nearest tenth of a year, how long must the person leave the
money in the bank until it reaches 14200 dollars?
The time taken to reach $14200 in the bank with 4.25% interest compounded is 50 years
The time taken to reach 14200 with interest compounded semi-annually can be calculated by
[tex]A = P (1 +\frac{R}{100n})^{nT}[/tex]
where A is the total amount at the end of the period
P is the principal amount
R is the rate of interest
n is the no. of interest compounded per year
T is the time period
We know that A = 14200
P = 9000
R = 4.25%
n = 2
By substituting these values, we get
14200 = 9000 [1 + (4.25 /200[tex]]^{2T}[/tex]
14200/9000 = [tex](1+0.02125)^{2T}[/tex]
1.5778 = [tex](1+0.02125)^{2T}[/tex]
1.5778 = [tex](1+0.02125)^{2T}[/tex]
1.5778 =[tex](1 +0.02125)^{2T}[/tex]
Taking logs on both sides,
log (1.5778) = log [tex](1+0.02125)^{2T}[/tex]
log (1.5778) = 2T log(1 +0.02125)
0.198 = 2T log(1.02125)
0.198 = 2T (0.00913)
0.918 = 0.01826 T
T = 0.918 / 0.01826

What is the together rate?The together rate is given by the sum of each separate rate.
For this problem, the rates are given as follows:
Ann: 1/10 = 0.1.Ben: 1/12 = 0.0833.Together: 1/x.Hence the amount completed in 2 days is:
2 x (0.1 + 0.0833) = 0.3666.
The amount it would take them to complete 100% of the project working together is found by the together rate as follows:
[tex]\frac{1}{x} = \frac{1}{10} + \frac{1}{12}[/tex]
[tex]\frac{1}{x} = \frac{6 + 5}{60}[/tex]
x = 60/11
x = 5.45 days.
The time it would take to do the remaining 100 - 36.66 = 63.34% of the project is:
0.6334 x 5.45 = 3.45 days.
It will take more 3.45 days to complete the work.
