The piecewise function for the Tax due on an income of x dollars are:
T(x) = 0.035x; if 0 < x ≤ $15,000T(x) = 525 + 0.0625 (x- 15,000); if 15,000 < x ≤ 30,000 T(x) = 1462.50 + 0.068 (x - 30,000); if 30,000 < xFrom the case, we know that there are 3 scenariois for filling tax due based on an individual's income, where:
Between $0 until $15,000 is taxed 3.5% of taxable incomeBetween $15,000 until $30,000 is taxed $525 plus 6.25% of excess over $15,000Over $30,000 is taxed $1462.50 plus 6.8% of excess over $30,000.To construct the piecewise function for the Tax due, we need to translate the given conditions into mathematical formulation.
We assume that:
T(x) = tax due
x = $ amount of taxable income
For taxable income between $0 until $15,000, the tax is 3.5% of taxable income; then:
T(x) = 3.5% x
T(x) = 0.035x
For taxable income between $15,000 until $30,000, the tax is $525 plus 6.25% of excess over $15,000. Then:
T(x) = 525 + 6.25% (x - 15,000)
T(x) = 525 + 0.0625 (x- 15,000)
Please note that the additional 6.25% only will be counted based on the remaining of the taxable income deducted by $15,000.
For taxable income over than $30,000, the tax is $1462.50 plus 6.8% of excess over $30,000. Then:
T(x) = 1462.50 + 6.8% (x - 30,000)
T(x) = 1462.50 + 0.068 (x - 30,000)
Please note that the additional 6.8% only will be counted based on the remaining of the taxable income deducted by $30,000.

Answers
The inverse function of f(x) = (x^2+1)^2 step by step is given below.
The inverse of f(x) is √(√x - 1).
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = (x² + 1)²
The steps for finding the inverse of a function.
Step 1:
Keep y = f(x)
y = (x² + 1)²
Step 2:
Interchange x and y.
x = (y² + 1)²
Step 3:
Solve for y.
x = (y² + 1)²
Square root on both sides.
√x = y² + 1
(√x - 1) = y²
Square root on both sides.
y = √(√x - 1)
Thus,
The inverse of f(x) is √(√x - 1).

The value of x is 13 and the angles in the triangle are 38,69 and 73 respectively.
What is triangle ?
Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
From the given figure,
In the given triangle ,
The triangles are 3x - 1 , 8x - 35 and 6x - 5
The sum of all angles is always is 180 degrees.
so,
we get,
3x - 1 + 8x - 35 + 6x - 5 = 180
17x - 41 = 180
17x = 180 + 41
17x = 221
x = 221 / 17
x = 13
so,
3x - 1 = 3*13 - 1 = 38
8x - 35 = 8* 13 - 35 = 104 - 35 = 69
6x - 5 = 6*13 - 5 = 78 - 5 = 73
Therefore, The value of x is 13 and the angles in the triangle are 38,69 and 73 respectively.

3. The marginal cost of producing a certain product is GHe 12 per unit, while the cost to produce
100units is GH¢1,500.
a) Find the cost function, C(x), given that it is linear.
b) Find the average cost per item to produce 50 units and 300 units.
Answers
Answer:
a) GH¢15x
b) GH¢15
Step-by-step explanation:
a) To find the cost function, C(x), given that it is linear, we need to find the slope and y-intercept of the line that represents the cost to produce x units of the product. We can use the point-slope form of a line to find the cost function: C(x) = mx + b, where m is the slope and b is the y-intercept.
We have two points: (100, GH¢1,500) and (0, GH¢0), which represents the cost to produce 100 units and 0 units, respectively. The slope can be found by dividing the change in y by the change in x:
m = (GH¢1,500 - GH¢0) / (100 - 0) = GH¢15
The y-intercept can be found by plugging in one of the points and solving for b:
GH¢1,500 = (GH¢15)(100) + b
GH¢1,500 = GH¢1,500 + b
b = GH¢0
So the cost function is C(x) = GH¢15x + GH¢0.
b) To find the average cost per item to produce 50 units and 300 units, we need to divide the total cost by the number of units produced.
For 50 units:
C(50) = GH¢15 * 50 + GH¢0 = GH¢750
Average cost = C(50) / 50 = GH¢15
For 300 units:
C(300) = GH¢15 * 300 + GH¢0 = GH¢4,500
Average cost = C(300) / 300 = GH¢15

Note that where Will C. Lowe wishes to purchase an ordinary whole life insurance policy with a face value Of $50,000, his annual premium, if his age for insurance purposes is thirty-one is: $7,665.
What is premium?The insured pays a premium to the insurer on a regular basis to cover his risk. The risk is transferred from the insured to the insurer under an insurance arrangement. The premium is the amount charged by the insurer for accepting this risk.
To compute the Premium Payable, you must apply the stipulated rate against the sum insured.
Since the Sum assured is $50,000; and
The applicable rate for a 31-year-old is 15.33%
Thus the Insurance Premium for an Ordinary Whole Life Insurance Policy is:
(50,000 * 15.33)/100
= 766500/100
= $7,665.
Thus Lowe to be entitled to an annual Life Insurance cover of $50,000 must pay $ $7,665 every year.

The distance of AB is 117.992 meters.
What is Law of Sines?Law of sines is a law in trigonometry which states that the ratios of the angle to the opposite side of a triangle are equal.
For triangle ABC,
sin A / a = sin B / b = sin C / c
where a, b and c are the sides opposite to the angles A, B and C respectively.
Here,
∠B = 112° 10' = 112° + 0.167° = 112.167°
∠C = 15° 20' = 15° + 0.333° = 15.333°
By the angle sum property of triangle,
∠A = 180° - (∠B + ∠C)
∠A = 180° - (112.167° + 15.333°)
= 52.5°
Using law of sines,
sin A / BC = sin C / AB
sin (52.5°) / 354 = sin (15.333°) / AB
AB = [354 × sin (15.333°)] / [sin (52.5°)]
AB = [354 × 0.264] / [0.793]
AB = 117.992 meters

Answers
The discounted price of the set of dishes would be = $63.89
How to calculate the discounted price?The original cost of the dishes = $57.68
The percentage increase of the cost of the dishes = 125%
That is,
= 125/100 × 57.68
= 7210/100 = $72.10+57.68 = $129.78
After one month, the store marked it down by 50%, therefore the discounted price;
= 50/100 × 129.78/1

let use the divisibility test and write which of the following numbers are exactly divisible by 7 a) 525 b)798 c)836 d) 3696 e) 5706
Answers
The numbers that are exactly divisible by 7 are;
a) 525
b) 798
d) 3696
How to use the rules of divisibility?To solve this, what we will do is to quote the divisibility rule for 7 here which is that;
For a 3 digit number abc to be divisible by 7 then it means that ab - 2c must be divisible by 7. Thus;
A) 525;
52 - 2(5)
= 52 - 10
= 42
42 is divisible by 7 and as such 525 is divisible by 7
B) 798;
79 - 2(8)
= 63
63 is divisible by 7 and as such 79 is divisible by 7
C) 836;
83 - 2(6)
= 83 - 12
= 71
71 is not divisible by 7 and as such 836 is not divisible by 7
D) 3696;
369 - 2(6)
= 357
35 - 2(7)
= 21
21 is divisible by 7 and as such 3696 is divisible by 7
E) 5706;
570 - 2(6)
= 558
55 - 2(8)
= 39
It's not divisible by 7 and so 5706 is not divisible by 7

Two different workers are producing a specialized part for a machine. The number of parts produced per hour by the workers are as follows:
Worker A: 5, 4, 4, 6, 7, 5, 6, 3
Worker B: 4, 8, 1, 9, 2, 9, 4, 3
Both workers averaged 5 parts per hour. Which worker has the higher variance and standard deviation?
Answers
The worker B has a higher variance of σ² = 9 and standard deviation of 3
What is Standard Deviation?The standard deviation refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Standard Deviation is calculated by
Each number's deviation from the mean must be determined, and then squared.
Next, add up all of these values.
Divide the result by the quantity of numbers.
Then calculate its square root.
Given data ,
Let the data of worker A = { 5, 4, 4, 6, 7, 5, 6, 3 }
Let the data of worker B = { 4, 8, 1, 9, 2, 9, 4, 3 }
Now , the mean of worker A = 5
The mean of worker B = 5
So , the standard deviation of worker A is calculated as
The sum of the difference of the data from mean is
SD = √ ( 5 - 5 )² + ( 5 - 4 )² + ( 5 - 4 )² + ( 5 - 6 )² + ( 5 - 7 )² + ( 5 - 5 )² + ( 5 - 6)² + ( 5 - 3 )² / 8
On simplifying the equation , we get
SD = √ ( 12/8 )
SD = √1.5
Standard deviation σ = 1.2247449
And , the variance of worker A is σ² = 1.5
Now ,
The standard deviation of worker B is calculated as
The sum of the difference of the data from mean is
SD = √ ( 5 - 4 )² + ( 5 - 8 )² + ( 5 - 1 )² + ( 5 - 9 )² + ( 5 - 2 )² + ( 5 - 9 )² + ( 5 - 4)² + ( 5 - 3 )² / 8
On simplifying the equation , we get
SD = √ ( 72/8 )
SD = √9
Standard deviation σ = 3
And , the variance of worker A is σ² = 9
Hence , the worker B has higher standard deviation

solve the inequality 
3/4 |1/3 + 2| < 6
a. x > -8 and x < -4
b. x > -30 and x < 2
c. x < -30 and x < 18
d. x > -30 and x < 18
Answers
The solutions of the equation are x < 18 and x < - 30.
Solution on inequalities:Solutions of equations are the numerical values of the variables that will satisfy the condition in the given equation. Similarly, the solutions of inequalities are the values of variables that can satisfy the given inequality.
We can solve an inequality by adding or subtracting the same integer on both sides, or we can multiply or divide by the same number on both sides until we get the value of 'x'.
Here we have
3/4 |1/3x + 2| < 6
We can solve the above equation as follows
3/4 |1/3x + 2| < 6
Multiply by 4 on both sides
=> 4 [ 3/4 |1/3x + 2| ] < 4 × 6
=> 3 |1/3x + 2| < 24
=> | x + 6| < 24
=> x + 6 < ± 24
=> x + 6 < 24 and x + 6 < - 24
Subtract - 6 on both sides
=> x + 6 - 6 < 24 - 6 and x + 6 - 6 < - 24 - 6
=> x < 18 and x < - 30
Therefore,
The solutions of the equation are x < 18 and x < - 30.
