Forty-five year old Jim Wiseman just got a new job earning $60,000 per year. He will save 10% of his income each year for his retirement at age 55. He must decide whether to invest his savings in Big Sky Bank which offers 20% compounded semi-annually or Valley Bank which offers 8% compounded quarterly. What compounded amount would he earn he chooses to invest his savings in Big Sky Bank? What compounded amount would he earn if he chooses to invest his savings in Valley Bank?
The compounded amount earned in Big Sky Bank is $40,365.00.
The compounded amount earned in Valley Bank is $13,248.24.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = 10% of 60,000
P = 6000
t = 10 years
Big sky Bank:
r = 20%
n = 2 (semiannually)
A = 6000 [tex](1 + 0.1)^{20}[/tex]
A = 6000 x [tex]1.01^{20}[/tex]
A = $40,365.00
Valley Bank:
r = 8%
n = 4 (quarterly)
A = 6000 [tex](1 + 0.02)^{40}[/tex]
A = 6000 x [tex]1.02^{40}[/tex]
A = $13,248.24
Thus,
Big Sky Bank compounded amount is $40,365.00.
Valley Bank compounded amount is $13,248.24.

A line passes through the point (3,2) and has a slope of 4
The equation of the line that passes through the point (3,2) and has a slope of 4 is; y = 4x - 10
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Point (3,2)
Then Slope m = 4
Now Write the equation as;
y - 2 = 4(x - 3)
y = 4x - 10
Hence, The equation of the line is; y = 4x - 10

Domain - the set of possible x-coordinates of a function.
Range - the set of possible y-coordinates of a function.
Question 25
Domain is:
x ∈ (- 6, 6), both ends excluded as open circles.Range is:
y ∈ [-5, 3), the lowest point is included as part of graph, the highest value is excluded as open circle..This is a function as it passes the vertical line test.
Question 26Domain is:
x ∈ [- 3, 7], both ends included as part of the graph.Range is:
y ∈ [-1, 5], both ends included as part of the graph.This is not a function as it fails the vertical line test.
Answer:
25) Domain: (-6, 6)
Range: [-5, 3)
26) Domain: [-3, 7]
Range: [-1, 5]
Step-by-step explanation:
Definitions
An open circle indicates the value is not included in the interval.A closed circle indicates the value is included in the interval.An arrow shows that the function continues indefinitely in that direction.Interval notation
( or ) : Use parentheses to indicate that the endpoint is excluded.[ or ] : Use square brackets to indicate that the endpoint is included.The domain is the set of all possible input values (x-values).
The range is the set of all possible output values (y-values).
Question 25From inspection of the graph, the endpoints of the continuous curve are:
(-6, -3) and (6, 3)As the endpoints are open circles, the values are excluded from the domain and range.
Therefore, the domain in interval notation is:
Domain: (-6, 6)The smallest y-value is y = -5 and the greatest y-value is y = 3.
Therefore, the range in interval notation is:
Range: [-5, 3)Question 26The graph is a conic section (ellipse) and therefore it is not a function.
The smallest x-value is x = -3 and the greatest x-value is x = 7.
The smallest y-value is y = -1 and the greatest y-value is y = 5.
Therefore, the domain and range in interval notation are:
Domain: [-3, 7]Range: [-1, 5]Given 2x + 3 is the hypotenuse, use the Pythagorean
Theorem to find the length of the side labeled x.
Answer:
24
Step-by-step explanation:
Given right triangle sides x, 2x-3, and 2x+3, you want to know the length of the side labeled x.
Pythagorean theoremThe Pythagorean theorem tells you the square of the hypotenuse is equal to the sum of the squares of the other two sides.
(2x +3)² = (2x -3)² +x²
4x² +12x +9 = 4x² -12x +9 +x²
x² -24x = 0 . . . . . subtract 4x² +12x +9
x(x -24) = 0 ⇒ x = 0 or 24
The length of the side labeled x is 24 units.

Mr. Rooks' bank pays 4-% interest per year. He has $17,000 in the bank. How much interest would he receive in 3 years?
Mr. Rooks would receive $2,040 in interest in 3 years.
The interest rate is given as 4%, which means that for every $100 Mr. Rooks has in the bank, he will receive $4 in interest per year.
To find the total interest Mr. Rooks will receive in 3 years, we need to multiply the annual interest rate by the number of years, and then multiply that result by the amount of money Mr. Rooks has in the bank.
In this case, the calculation would be as follows:
Annual interest rate × number of years × amount in the bank = total interest
(4 / 100) × 3 × $17,000 = $2,040
Therefore, Mr. Rooks would receive $2,040 in interest in 3 years.

What is Integration?An integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data.
The given integral is [tex]\int\dx \frac{2x+11}{x^{2} -x-2} dx[/tex]

What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The function is given below.
f(x) = (x⁴ + 2x³ - 3x² - 4x - 12)
Factorize the expression, then we have
f(x) = (x⁴ + 2x³ - 3x² - 4x - 12)
f(x) = x⁴ - 2x³ + 4x³ - 8x² + 5x² - 10x + 6x - 12
f(x) = x³(x - 2) + 4x²(x - 2) + 5x(x - 2) + 6(x - 2)
f(x) = (x - 2)(x³ + 4x² + 5x + 6)

What is inequality?
In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.
Consider, the given inequality
K/2 - 20 ≥ -18
Add 20 on both sides,
K/2 - 20 + 20 ≥ -18 + 20

Triangles = VWX and ZYX
The ASA similarity theorem implies that the corresponding angles of the triangles in question are similar and the sides between these angles are congruent
From the question, we can see that the following corresponding angles on the triangles:
Angles W and Y
Angles X and X
This implies that these angles are congruent angles
For the triangle to be congruent by ASA, the following sides must also be congruent
WX must be congruent to YX

Also provided below is the ANOVA output for comparing average hours across educational attainment categories. (a) Write the hypotheses for testing for a difference between the average number of hours spent on child care across educational attainment levels. (b) What is the conclusion of the hypothesis test?
(a). The alternative to the null hypothesis, H₀ = μ₁= μ₂ = μ₃=μ₄= μ₅ is Hₐ: At least two 1s are unequal. (b). Refuse H₀ If p-value is less than 0.05, the 5% presumed threshold of significance is exceeded.

To determine the median of a collection of data, add all of the values and divide the result by the total number of values.
Briefing:a). The study's goal is to determine if there is discernible variation in the typical quantity of time spent on childcare services across levels of educational achievement.
Null hypothesis, H₀ = μ₁= μ₂ = μ₃=μ₄= μ₅
(The average quantity of time spent on child rearing across educational levels does not change much.)
Alternative hypothesis, Hₐ : At least two μ₁s are unequal.
