The number of years until the book value of the boat is $ 48, 000, can be found to be 2 years
How to find the number of years ?To find the number of years till the book value of the boat is $ 48, 000, you first need to find the depreciation rate per year by the formula :
= ( Purchase price of boat - Resale value ) / Useful life
= ( 51, 000 - 42, 000 ) / 6
= 9, 000 / 6 years
= $ 1, 500 per year
In the first year, the value of the boat would depreciate to:
= 51, 000 - 1, 500
= $ 49, 500
In the second year, the value would depreciate to:
= 49, 500 - 1, 500
= $ 48, 000
It therefore takes 2 years for the book value to be $ 48, 000.

What is an absolute value function?In Mathematics, an absolute value function can be defined as a type of function that is composed of an algebraic expression, which is placed within absolute value symbols and measures the distance of a point on the x-coordinate to the x-origin (0) of a cartesian coordinate (graph).
Mathematically, an absolute value function can be represented by this mathematical expression:
|x| = x, x ≥ 0.
|x| = x, x < 0.
Generally speaking, an equation or absolute value function would have exactly one (1) solution when there is only one (1) value for the variable (W) that makes the equation to be true as shown below:

What is a measure of an angle?
Since an angle is measured in degrees, the term "degree measure" is used. Since 360 degrees make up one full revolution, it is divided into 360 equal sections. A degree is what the revolution is at each stage.
Here, we have
The measure of ∠AOC is 90°.
3x° + 46° +14° = 90°
3*10° + 46 + 14° = 90°

Match each compound inequality on the left to the graph that represents its solution on the right.
Note that equation 1 matches the Line Graph in option (B), equation 2 matches option (C), and equation 3 matches option (A).
How would you define a Line Graph?It is a graph that depicts a line connecting many points or a line indicating the relationship between the points. The graph depicts quantitative data between two changing variables by connecting a sequence of succeeding data points with a line or curve.
With regard to the above-given graphs,
The inequalities are given as
1. 4x + 3 > 15 or —6x ≥ 12
2. —8x > —24 and —10 ≤ 2x -6
3. -29 ≤ 9x -2 < 16
Note that the way to identify the plots on the line graphs is by solving the above equations.
1) 4x + 3 > 15 or —6x ≥ 12
4x + 3 > 15 can be solved by subtracting 3 from both sides, resulting in 4x > 12. Dividing both sides by 4 gives x > 3.-6x ≥ 12, can be solved by dividing both sides by -6, resulting in x ≤ -2.2) —8x > —24 and —10 ≤ 2x -6
To solve for x in —8x > —24, divide both sides by -8
x > 3;
So solve for —10 ≤ 2x -6; add 6 from both sides and divide by 2
-4/2 ≤ x
-2 ≤ x or x ≥ -2
3) -29 ≤ 9x -2 < 16
To solve this inequality, you can start by isolating the variable on one side of the inequality. To do this, you can add 2 to both sides to get:
-29 + 2 ≤ 9x < 16 + 2
-27 ≤ 9x < 18
Now divide both sides by 9 to get:
-3 ≤ x < 2
This means that x can be any number that is greater than or equal to -3 and less than 2.
Given the above results, it is correct to state that equation 1 matches option (B), equation 2 matches option (C), and equation 3 matches option (A).

The altitude of the hypotenuse of a right triangle divides the hypotenuse into two segments. If the ratio of lengths of the segments is 1:9 and the length of the altitude is 6 meters, find the lengths of the two segments?
Answer:
2 m18 mStep-by-step explanation:
You want the lengths of the segments of the hypotenuse of a right triangle when an altitude of 6 m divides the hypotenuse into parts with the ratio 1:9.
Geometric meanThe altitude to the hypotenuse of a right triangle is the geometric mean of the parts it divides the hypotenuse into. If the shorter part is x, then the longer part is 9x, and their geometric mean is ...
6 = √(x(9x)) = 3√x² = 3x
x = 2 . . . . . . . divide by 3
The length of the shorter segment is 2 m; the longer one, 18 m.
In Exercises 13-15, use f(x) = x² and g(x) = 4x - 6 to find h(x).
13. h(x) = f(x) - g(x)
14. h(x) = f(g(x))
15. h(x) is the inverse of g(x)
The value of the function h(x) is x² - 4x +6 and 4-6 x².
What is a formula for a function?Any function's x-intercept, y-intercept, and slope can be calculated using function formulas. You could also determine a quadratic function's vertex. Additionally, the function can be graphed for various x values.
Simply adding the values of the functions f(x) and g will yield the value of the function f(x) and g(x).
Therefore, we get
f(x) = x² and we have g(x) = 4x - 6
h(x) = f(x) - g(x)
h(x) = x² - 4x +6
h(x) = f(g(x))
= x²( 4x - 6)
= 4-6 x²
h(x) is the inverse of g(x)
= inverse of 4x - 6
= 1/ 4x - 6

The probability of each result are as follows: • Probability of 0.42 that people liked pie • Probability of 0.90 that people liked cake or pie • Probability of 0.12 that people liked both cake and pie Use a Venn Diagram to support your calculations for the following questions:
a) Determine the probability that a person will like cake.
B) Determine the probability that a person at the festival does not like either of these two desserts.
C) Are the event liking cake and liking pie mutually exclusive or non-mutually exclusive? Justify your answer.
a) The probability that a person will like cake is given as follows: 0.6 = 60%.
b) The probability that a person does not like any of the two desserts is given as follows: 0.1 = 10%.
c) The events are non-mutually exclusive, as the probability of liking both is different of zero.
What is a Venn probability?In a Venn probability, two events are related with each other, as are their probabilities.
The "or probability" is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
The events for this problem are given as follows:
Event A: person likes pie.Event B: person likes cake.The probabilities for this problem are given as follows:
P(A or B) = 0.9, P(A) = 0.42, P(A and B) = 0.12.
Hence the probability that a person likes cake is given as follows:
0.9 = 0.42 + P(B) - 0.12
0.3 + P(B) = 0.9
P(B) = 0.6.
Probability of 0.90 that people liked cake or pie, hence the probability that a person likes neither is of:
1 - 0.9 = 0.1 = 10%.

Scores on the Wechsler Adult Intelligence Scale (a standard IQ test) for the 20-to-34 age group are approximately normally distributed with μ = 110 and σ = 25. What percent of people aged 20 to 34 have IQs between 125 and 150?
The percentage of people aged 20 to 34 that have IQs between 125 and 150 of people aged 20 to 34 have IQs between 125 and 150 is 21.94%
What is percentage?Percentage simply means a proportion of the number as a fraction of 100
What percent of people aged 20 to 34 have IQs between 125 and 150?
Let X = Scores on the standard IQ test for the 20 to 34 age group
This implies that X ~ Normal(x=110, б² = 25)
The z-score probability distribution for the normal distribution is given by; Z = (x-ц)/б ~ N(0,1)
Recall that population mean = 110 and standard deviation = 25
Now, the percent of people aged 20 to 34 have IQs between 125 and 150 is given by = P(125 < X < 150) = P(X < 150) - P(X 125)
P(X < 150) = P( < ) = P(Z < 1.60) = 0.9452
P(X 125) = P( ) = P(Z 0.60) = 0.7258
The above probability is calculated by looking at the value of x = 1.60 and x = 0.60 which has an area of 0.9452 and 0.7258.
Therefore, P(125 < X < 150) = 0.9452 - 0.7258 = 0.2194 or 21.94%

Minimum or maximum value
The minimum is the smallest value in the data set. The maximum is the largest value in the data set.
To find the minimum or maximum value of a function:We will set the first derivative of the function to zero and solve for x to get the critical point. If we take the second derivative or f''(x), then we can find out whether this point will be a maximum or minimum. If the second derivative is positive, it will be a minimum value.
A minimum or a maximum is called an extreme point. A local extreme point is the smallest or largest value in its neighborhood. If it is also the smallest or largest at the entire domain of the function, it is called a global extreme point. The local minima and maxima can be found by solving f'(x) = 0.

2x + y = 180
x - y = 30
The value of x=70 and y=40
The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with the multiplication or division of coefficients of the variables.
Here, 2x+y=180
x-y= 30
Here, the coefficient of y in these two equations are equal and have opposite signs. so,
2x+y= 180
x-y= 30
Now adding equation 1 and equation 2
We get,
3x= 210
x= 210/3
x= 70
Now, to find y:
Putting the value of x in equation 2
x-y= 30
70-y= 30
y= 70-30
y= 40
so, the value of x and y are 70 and 40

Answer:
(a, b, c) = (-3, -2, -4)
Step-by-step explanation:
You want to solve the system of 3 equations in 3 variables shown in the attached figure.
SolutionThe easiest solution is one provided by a suitable calculator (attached). It tells you ...
a = -3b = -2c = -4The "work" is entering the problem into the calculator.
Ad hocWe notice the sum of 'a' coefficients is zero, so we can add the three equations to get ...
(4a +5b -6c) +(-3a -2b +7c) +(-a +4b +2c) = (2) +(-15) +(-13)
7b +3c = -26 . . . . . simplify
Multiplying the third equation by 4 and adding that to the first equation gives ...
4(-a +4b +2c) +(4a +5b -6c) = 4(-13) +(2)
21b +2c = -50 . . . . . simplify
Now, we have two equations in two unknowns.
Multiplying the first equation above by 3 and subtracting this last equation eliminates the b term to give ...
3(7b +3c) -(21b +2c) = 3(-26) -(-50)
7c = -28 . . . . . simplify
c = -4 . . . . . . . divide by 7
Using this in the first "ad hoc" equation, we can find b:
7b +3(-4) = -26
7b = -14 . . . . . . . . add 12
b = -2 . . . . . . . . divide by 7
And the values of b and c can go into the last of the original equations to give ...
-a +4(-2) +2(-4) = -13
-a = 3 . . . . . add 16
a = -3 . . . . . multiply by -1
The solution is (a, b, c) = (-3, -2, -4).
__
Additional comment
The given solution is "ad hoc" because we decide how we're going to approach the solution based on the coefficients we see. Here, we are solving by "elimination," performing as little arithmetic as possible.
The third equation suggests we could make a substitution for 'a':
a = 4b +2c +13
That substitution would give a different set of equations in 'b' and 'c' than the ones shown above.
The second attachment shows a graphical solution to the system. It shows (a, b, c) = (-3, -2, -4). The graphing program requires the use of x and y instead of 'a' and 'b' for the variables.
Four methods of solving the system have been described. Take your pick. The calculator solution was the easiest, requiring each number to be entered once.
