Suppose that you invest $5873 in an account that earns interest at an APR of 4.4%, compounded monthly. Determine the accumulated balance after 7 years.
Answers
P = $5873, the principal
r = 4.4% = 0.044, the interest rate
n = 12, twelve monthly compoundings in a year
t = 7 years
Note that
n*t = 12*7 = 84
r/n = 0.044/12 = 0.003667
The accumulated balance after 7 years is
A = 5873*(1 + 0.003667)⁸⁴ = $7,986.90
Answer: $7,986.90
Help Dana find the sum 346 421 152
For numbers 13a-13d, select yes or no to tell Dana when to regroup
Answers
346

+152
We start on the ones place 6 + 1 + 2 = 9, the sum of the digits in the ones place is not up to 10, we will not regroup this ones place.
So, basically the answer to 13a is NO.
Since we are not able to regroup the ones place there is no regrouped tens to add, therefore the answer to 13b is also NO.
Next is the tens place, 4 +2 +5 = 11, the sum of the digits in the ones place is up to 10 so we regroup the tens place.
Thus, the answer to 13c is YES.
Since, we regrouped the ones place, we add the regrouped hundred, thus the answer to 13d is YES.
Finally, for the hundred place, 1 + 3 + 4 + 1 = 9
Therefore, the sum of

If P is the midpoint of XY,XP=8x-2 and PY=12x-30 find the value X
Answers
P being the midpoint, will cut XY in two equal halves.
Using the midpoint concept, it is found that x = 7.
----------------------
The midpoint divides a segment into two segments of equal length.P is the midpoint of XY, thus XP = PY.----------------------
[tex]XP = 8x - 2[/tex]
[tex]PY = 12x - 30[/tex]
Since they are equal, we use it to find x.
[tex]XP = PY[/tex]
[tex]8x - 2 = 12x - 30[/tex]
[tex]4x = 28[/tex]
[tex]x = \frac{28}{4} = 7[/tex]
The value of x is 7.

find all sets of three consecutive even integers whose sum is greater than 102 and less than 116
Answers
there sum will be
2k+2(k+1)+2(k+2)
2k+2k+2+2k+4
6k+6
so setting the inequality
102<6k+6<116
subtracting 6 from all sides
96<6k<110
16<k<18.3333
since k is an integer
the only integers between 16 and 18.3
are 17 and 18
so
when k=17
2(17),2(17+1),2(17+2)
34,36,38
when k=18
2(18),2(18+1),2(18+2)
36,38,40
so to check are soultion we substitute
34+36+38=108 which is between 102 and 116
36+38+40=114 which is between 102 and 116
so our soultion is correct
the final answer will be

in which number does the 6 have a value that is one tenth the value of the 6 in 34, 761
Answers
The 6 in 600 has a value one tenth the value of the 6 in 34, 761.
Explanation:The question asks in which number does the 6 have a value that is one tenth the value of the 6 in 34, 761.
To find the answer, we need to compare the place value of the 6 in both numbers. In 34, 761, the 6 is in the thousands place, and its value is 6,000. To have a value that is one tenth of 6,000, the 6 would need to be in the hundreds place in the other number.
So, the number in which the 6 has a value one tenth the value of the 6 in 34, 761 would be 600.
Final answer:
The number 6 in 2,001.06 is one-tenth the value of the 6 in 34,761.
Explanation:
The number 6 in 34,761 has a value that is one-tenth the value of the 6 in the number 2,001.06.
To find this, we can compare the place values of the two 6's. The 6 in 34,761 is in the ones place, while the 6 in 2,001.06 is in the tenths place.
Since the tenths place is one place to the right of the ones place, the value of the 6 in 2,001.06 is one-tenth the value of the 6 in 34,761.

Consider a point on the trans-australian highway, where two old wombats live. arrivals of cars at this point follow a poisson distribution; the average rate of arrivals is 1 car per 12 seconds.
Answers
This is a Poisson distribution with a mean of 1 car every 12 seconds.
Part A:
The probability of a Poisson distribution is given by:
[tex]P(X=x)= \frac{e^{-\lambda}\lambda^x}{x!} [/tex]
Given tha one of the old wombats requires 12 seconds to cross the highway, and he starts out immediately after a car goes by.
The probability he will survive is the probability that no car passes through the point in the next 12 seconds.
[tex]P(x=0)= \frac{e^{-1}(1)^0}{0!} =e^{-1}=0.368[/tex]
Therefore, the probability that he will survive is 0.368
Part B:
Given that at the same point of the highway there is another old wombat, slower but tougher than in the previous exercise. He requires 24 seconds to cross the road, but it takes two cars to kill him. (A single car won’t even slow him down. The arrival rate of cars is still one car per 12 seconds.)
Since the arrival rate of cars is one car per 12 seconds, then, in 24 seconds the arrival rate is 2 cars. (i.e. λ = 2)
The probability that he survives is the probability that 2 cars did not pass through the point.
[tex]P(X\neq2)=1-P(X=2)=1- \frac{e^{-2}(2)^2}{2!} =1-0.135=0.865[/tex]
Marcel is planning a vacation. The travel agent says the average high temperature at the resort is 20 degrees Celsius. What is the equivalent Fahrenheit temperature
Answers
The equivalent Fahrenheit temperature for 20 degrees Celsius is 68 degrees Fahrenheit.
Explanation:To convert Celsius to Fahrenheit, you can use the formula: F = (C × 9/5) + 32
Using this formula, we can calculate the equivalent Fahrenheit temperature for 20 degrees Celsius:
F = (20 × 9/5) + 32 = 68 degrees Fahrenheit
Alan is building a garden shaped like a rectangle with a semicircle attached to one short side. If he 21) has 20 feet of fencing to go around it, what dimensions will give him the maximum area in the garden?
Answers
Let the short side be W
The half circumference of the semi-circle = .5 * pi *W
2Lengths + width + semicircle = 20 ft
2L + W + (.5*pi*W) = 20
2L + W + 1.57W = 20
Combine like terms
2L + 2.57W = 20
Simplify divide by 2
L + 1.285W = 10
L = (10 - 1.285W); for substitution:
Get the area equation:
Rectangle area + semicircle area
A = L * W + (.5*pi*(.5W) ^2)
A = LW + (1.57*.25W^2)
A = LW + .3925W^2
Replace L with (10-1.285W)
A = W(10-1.285W) + .3925W^2
A = -1.285W^2 + .3925W^2 + 10W
A = -.8925W^2 + 10W
Find W by finding the axis of symmetry of this equation a=-.8925, b=10
W = -10 / 2 * (-.8925)
W = -10 / -1.785
W = 5.60 is the width for max area
then we solve for the length
L = 10 - 1.285(5.60)
L = 10 – 7.20 = 2.8 ft is the length
Then, Check the perimeter
2(2.8) + 5.60 + 1.57(5.60) = 20ft
5.6 + 5.6 + 8.736 = 20ft
Rectangle: 2.8 by 5.60 has semicircle circumference 8.736 has a maximum area: (2.8*5.60)
+ (.5 * pi * 2.8 ^ 2)
=15.68 + 12.31
