The expression for the interest earned on each account and the balance after 3 years are;
1) Interest = P(1 + 0.039t)
Balance = $485.90
2) Interest = P(1.039)^(t)
Balance = $487.91
3) Interest = P(1.039)^(t)
Balance = $487.91
4) Interest = 435e^(0.039t)
Balance = $488.99
How to calculate the simple interest?We are given different formulas for interest and we are told to find the balance of each option after 3 years. Thus, we have;
1) P(1 + rt)
Where;
P is principal = $435
r is rate = 0.039
t is time = 3 years
We have;
Balance = 435(1 + (0.039 * 3))
Balance = $485.90
2) P(1 + (r/n))^(nt)
Where;
P is principal = $435
r is rate = 0.039
t is time = 3 years
n is number of times interest is compounded per year = 1 (because it is yearly)
Thus;
A = 435(1 + (0.039/1))^(3 * 1)
A = $487.91
3) Same as 2 above
4) P₀e^(rt)
where;
P₀ is principal = $435
r is rate = 0.039
t is time = 3 years
Thus;
A = 435(e^(0.039 * 3)
A = $488.99

The set of events that the sum of the numbers showing face up is at least 9 is E = {36, 45, 46, 54, 55, 56, 63, 64, 65, 66} and the probability is 5/18.
In the roster form, the elements (or members) of a set are listed in a row between curly brackets. For the event that the sum of the numbers showing face up is at least 9 and is written as a set, look at the sum of values of blue and gray dies that has values greater than equal to 9.

(please explain :))A 35 foot ladder is set against the side of a house so
that it reaches up 21 feet. If Elijah grabs the ladder at its
base and pulls it 4 feet farther from the house, how far up
the side of the house will the ladder reach now? (The
answer is not 17 ft.) Round to the nearest tenth of a foot.
Answers
Answer:
21.4
Step-by-step explanation:
If the ladder originally reaches up 21 feet on the side of the house, and Elijah pulls it 4 feet farther away from the house, the distance from the base of the ladder to the side of the house will increase by 4 feet. This means that the new distance from the base of the ladder to the side of the house will be 21 feet + 4 feet = 25 feet.
Since the height of the ladder is the same, and the base of the ladder is now 25 feet from the side of the house, the ladder will still reach up 21 feet on the side of the house. Therefore, the new distance from the top of the ladder to the ground will be 25 feet - 21 feet = <<25-21=4>>4 feet.
To find the new distance from the top of the ladder to the side of the house, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, we have a right triangle with legs of lengths 21 feet (the height of the ladder) and 4 feet (the distance from the top of the ladder to the ground), and we want to find the length of the hypotenuse (the distance from the top of the ladder to the side of the house). We can use the formula c^2 = a^2 + b^2 to find the length of the hypotenuse:
c^2 = 21^2 + 4^2
= 441 + 16
= 457
c = sqrt(457)
= 21.37
Therefore, the distance from the top of the ladder to the side of the house is 21.37 feet, and the ladder will reach up 21.37 feet on the side of the house after Elijah pulls it 4 feet farther away. Round to the nearest tenth of a foot, the ladder will reach up 21.4 feet on the side of the house.
The answer would not be 17 feet because the height of the ladder and the distance from the base of the ladder to the side of the house are two separate and independent quantities. The height of the ladder is a fixed distance and does not change, regardless of the position of the base of the ladder. Therefore, even if Elijah pulls the ladder 4 feet farther away from the house, the height of the ladder will still be 21 feet and the ladder will still reach up 21 feet on the side of the house. The only change will be the distance from the base of the ladder to the side of the house, which will increase by 4 feet.

What is a value ?
Value in ethics and social sciences refers to the degree of significance of something or an activity, with the goal of deciding the best courses of action to take or the best ways to live, or to define the significance of certain activities.
The value describes the value of each digit in relation to its position in the number. The place value and face value of the digit are multiplied to arrive at the answer. Value equals Place Value minus Face Value. Consider this: If we take 45 into consideration. The tens column is where the fourth digit is located in this instance.
The things that someone values are known as their values. In other terms, values are what a person or a group of people see as "important."
(a)
DF for Factor A = 6 - 1 = 5
DF for Factor B = 4 - 1 = 3
DF for Interaction of Factor A and B = 5*3 = 15
Number of replications per cell = 6
Total no of observations = 6*(N_Factor A)*(N_Factor B) = 6 * 6 * 4 = 144
DF Residuals = 144 - 5 - 3 - 15 - 1 = 120
Total DF = N - 1 = 143
(b) Critical F values
Factor A = F(5,120) = 2.30
Factor B = F(3,120) = 2.69
Interaction = F(15,120) = 1.76
(c) As F statistics for Factor A, Factor B as well as Interaction is >> Fc, Hence we can Reject the Null Hypothesis and warrant the rejection of the claim for equality of means
Hence there is a significant difference in Factor A and there is a significant difference in Factor B.

The growth constant is 1.0986 and the trout population will increase to 14600 after 2.1 years. The result is obtained by using the logistic equation.
How to find the increase of population?The increase of population can be found by using the logistic equation. It is
[tex]P(t) = \frac{K}{1 + Ae^{-kt} }[/tex]
Where
P(t) = population at time t (in years)K = carrying capacityA = (K- P₀)/P₀k = growth constant of proportionalityt = time (in years)Sunset Lake is stocked with the rainbow trout. We have
P₀ = 2800P(1) = 7000K = 28000Find the growth constant k and time t when P(t) = 14600!
A = (K - P₀)/P₀
A = (28000 - 2800)/2800
A = 25200/2800
A = 9
After 1 year, we have 7000 rainbow trout. The growth constant is
[tex]7000 = \frac{28000}{1 + 9e^{-k(1)} }[/tex]
[tex]1 + 9e^{-k} = 4[/tex]
[tex]9e^{-k} = 3[/tex]
[tex]e^{-k} = \frac{1}{3}[/tex]
k = - ln (1/3)
k = 1.0986
Use k value to find the time when the population will increase to 14600!
[tex]14600 = \frac{28000}{1 + 9e^{-1.0986t} }[/tex]
[tex]1.9178 = 1 + 9e^{-1.0986t}[/tex]
[tex]0.9178 = 9e^{-1.0986t}[/tex]

the base of a solid is a circular disk with radius 3. find the volume of the solid if parallel cross-sections perpendicular to the base are isosceles right triangles with hypotenuse lying along the base.
Answers
the base of a solid is a circular disk with radius 3. Therefore, the volume of the solid is 27π.
The volume of a solid is determined using the formula V = πr²h, where r is the radius of the base and h is the height of the solid. In this problem, the base is a circular disk with radius 3, and the cross-sections are isosceles right triangles with hypotenuse lying along the base. Since the cross-sections are isosceles right triangles, the height of each triangle is equal to the radius of the base, which is 3. Therefore, the height of the solid is also 3. Substituting these values into the formula gives V = π(3)²(3), which simplifies to V = 27π.
Therefore, the volume of the solid is:

Answers
Using the Pythagorean triplet, the value of AB is 2.
In the given question we have to find the length of AB.
From the given diagram we can see that;
ED = 2, DC = 8 and BC = 6.
To solve this question we use the Pythagorean Triplet.
Pythagorean triples consist of the three positive numbers a, b, and c, where a^2+b^2 = c^2. The symbols for these triples are (a,b,c). Here, a represents the right-angled triangle's hypotenuse, b its base, and c its perpendicular.
Since we have to find the value of AB.
So we can write it as
EC^2 = AE^2+AC^2
(ED+DC)^2 = AE^2+(AB+BC)^2
Now putting the value
(2+8)^2 = AE^2+(6+AB)^2
10^2 = AE^2+(6+AB)^2
As we know that triplet (6,8,10).
The value of EC is 10, AE = 6, the value of AC can't be 6 because one part of value of AC is already given 6. So the value of AC is 8. AS BC=6, so AB=2.
Hence, the value of AB is 2.

Answers
Answer:
-12
Step-by-step explanation:
If g(x) = 5x, then plugging in -60 for g(x) gives -60 = 5x. Dividing both sides of this equation by 5 gives -12 = x. Therefore, the correct answer is -12.
A student made a mistake while using similar triangles to find the missing side length indicated by the letter z in the diagram Analyze the student's work and find the state. Explain what was done incorrectly and find the correct solution Student's work to find the value of x
Answers
The students ratio expressed in fraction as 6/4 = 4/x is incorrect for the similar triangles, and the correct ratio is x : 3 = 10 : 6 expressed in fraction as x/3 = 10/6. The value for x = 5.
How to calculate for x for the similar trianglesSince the triangles are similar, it implies that the length 3 of the smaller triangle is similar to the length x of the larger triangle,
Also the length 6 of the smaller triangle is similar to the length of the larger triangle (4 + 6 = 10).
So it will be wrong to write 6/4 = 4/x, rather the correct fraction will be;
x : 3 = 10 : 6
which when expressed as fraction, we get;
x/3 = 10/6
x = (10 × 3)/6
x = 30/6
x = 5
Therefore, the students expression 6/4 = 4/x is incorrect representation for the lengths of the similar triangles. And the correct expression is x/3 = 10/6, which gives us the value of x equal to 5.
