Round your answer to the nearest tenth.
Answers
If the archaeologist found a fossil whose length is 489.44 inches, using the conversion table, the length in feet, to the nearest tenth, is 40.8 feet.
What is the conversion table?The conversion table refers to the tabulated standard units of measurement, showing temperature, length, area, volume, weight, and metric conversions
For instance, the conversion table shows that 12 inches equal 1 foot.
The length of the fossil = 489.44 inches
12 inches = 1 foot
489.44 inches = 40.8 feet (489.44 ÷ 12)
Thus, using the conversion table, which relies on multiplication or division operations using the conversion factors, the length in feet of the fossil is 40.8 feet.

(d) now solve the linear equation in part (b), and find the solution that satisfies the initial condition in part (c).
Answers
The Bernoulli differential equation is a nonlinear ordinary differential equation of the form:
dy/dx + P(x)y = Q(x)y^n, where n ≠ 0, 1.
For n = 0 or n = 1, the equation is linear. For other values of n, a common technique to linearize the equation is to make the substitution y = v^(-1/n-1). The resulting equation is:
dv/dx + (P(x) + Q(x)/v^(1/n-1)) * (1/n-1) * v^(1/n-2) * dv/dx = 0.
For the initial value problem given, we have P(x) = -1/x, Q(x) = -5, and n = 2.
We make the substitution y = v^(-1), so v = y^(-1), and dv/dx = -y^(-2)dy/dx. The equation becomes:
-y^(-2)dy/dx + (-1/x - 5y^2) = 0.
We have the initial condition y(1) = 1/5. In terms of v, the initial condition becomes v(1) = 1/(1/5)^2 = 25.
Now, the differential equation is linear, and we can solve it using standard methods, such as separation of variables. To find the solution that satisfies the initial condition, we may use numerical methods such as the Euler method or Runge-Kutta method.

What is the probability that either event will occur?From the question, we have the following parameters that can be used in our computation:
Event A = 8Event B = 7Other Events = 30Using the above as a guide, we have the following:
Total = A + B + C
So, we have
Total = 8 + 7 + 30
Evaluate
Total = 45
So, we have
P(A) = 8/45
P(B) = 7/45
For either events, we have
P(A or B) = 8/45 + 7/45
P(A or B) = 15/45
Evaluate
P(A or B) = 0.33
Hence, the probability that either event will occur is 0.33

What is the total expense for manufacturing 400 tables at Woodlike Inc., if the fixed costs are $1,702,300 and each tables variable cost is $21?
Answers
EXPLANATION
Assuming that the number of tables should be multiplied by the variable cost by each table, we can apply the following equation:
\(Expenses=\text{ Fixed Cost + Variable Cost }\cdot\text{ Number of manufactured tables}\)Replacing terms:
\(\text{Expenses = 1,702,300 + 21 }\cdot\text{ 400}\)Multiplying numbers:
\(\text{Expenses = 1,702,300 + 8,400 = 1,710,700}\)In conclusion, the total expense cost is $ 1,710,700
If u = 15, t = 8, s = 40 and s (u+v)t 2 evaluate v.
Answers
The value of v is -12.5 when u = 15, t = 8, and s = 40.
According to the question,
We have the following expression:
s = (u+v)\(t^{2}\)
We have the following values:
u = 15, t = 8, s = 40
Now, we can easily find the value of v by putting all these values in the given expression.
So, we have the following expression:
40 = (15+v)8*8
40 = (15+v)16
Multiplying 16 into the bracket:
40 = 15*16+16v
40 = 240+16v
Subtracting 240 from both sides:
40-240 = 16v
-200 = 16v
Dividing by 16 on both sides:
-200/16 = v
v = -12.5
Hence, the value of v is -12.5 when u = 15, t = 8, and s = 40.

A piece of wood is in the shape of a rectangular prism with a length of 10 inches, a width of 4 inches, and a height of 5 inches. You cut the wood in half to form two pieces of wood, each with a length of 5 inches. What is the percent increase in the total surface area? Round your answer to the nearest hundredth, if necessary. %
Answers
Answer: 18.18%
Step-by-step explanation:
First, let's calculate the surface area of the original piece of wood. The surface area (SA) of a rectangular prism is given by the formula:
\($$SA = 2lw + 2lh + 2wh$$\)
where \(\(l\)\) is the length, \(\(l\)\) is the width, and \(\(h\)\) is the height. For the original piece of wood, \(\(l = 10\) inches\), \(\(w = 4\) inches\), and \(\(h = 5\) inches\).
After the piece of wood is cut in half, the length becomes 5 inches, but the width and height remain the same. So, for each of the two new pieces of wood, \(\(l = 5\) inches\), \(\(w = 4\) inches\), and \(\(h = 5\) inches\). The total surface area of the two new pieces of wood is twice the surface area of one of the new pieces.
The percent increase in the total surface area is given by the formula:
\($$\text{Percent Increase} = \frac{\text{New Total SA} - \text{Original SA}}{\text{Original SA}} \times 100\%$$\)
Let's calculate these values.
The percent increase in the total surface area when the piece of wood is cut in half is approximately 18.18%.
The Demand function for a product is given by:
D(q) = - 0.0003q^2 - 0.04q + 23.56
where q is the number of units sold and D(q) is the corresponding price per unit, in dollars. What is the average rate of change of Demand between 40 and 175 units sold?
Answers
Answer:
The average rate of change of Demand between 40 and 175 units sold is of -0.1045.
Step-by-step explanation:
Average rate of change:
The average rate of a function f(x) in an interval [a,b] is given by:
\(A = \frac{f(b) - f(a)}{b - a}\)
In this question:
\(D(q) = -0.0003q^2 - 0.04q + 23.56\)
What is the average rate of change of Demand between 40 and 175 units sold?
\(a = 40, b = 175\). So
\(D(40) = -0.0003*40^2 - 0.04*40 + 23.56 = 21.48\)
\(D(175) = -0.0003*175^2 - 0.04*175 + 23.56 = 7.3725\)
So
\(A = \frac{f(b) - f(a)}{b - a} = \frac{7.3725 - 21.48}{175 - 40} = -0.1045\)
The average rate of change of Demand between 40 and 175 units sold is of -0.1045.

How to solve Algebraic Word Problems?1) We are told that the front cover and the back cover have a thickness of 1/4 inches and they also have a thickness of 1/4 inch. Thus;
The addition of both gives to the book thickness of;
1/4 + 1/4 = 1/2 inch, despite how many pages the book has.
We are told that for every hundred pages, a thickness of 1/4 inch is added to the book, then the equation is:

Step-by-step explanation:
We have to find also the area of the rectangle, then we will find the area of the circle and divide by 2 because here is a half circle.
area of the rectangle = b x h
area of the rectangle = 6 x 6
area of the rectangle = 36
diameter = 6
r = d : 2
r = 6 : 2
r = 3 ft
area of the circle = π x r²
area of the circle = 3,14 x 3 ft
area of the circle = 9,42 ft
area of half of circle = 9,42 : 2 = 4,71 ft
area of this figure = area of rectangle - area of half of the circle
area of this figure = 36 - 4,71
area of this figure = 31,29
So the area of this figure is 31,29.

Answers
a) The probability that exactly one of them will be a girl = 0.3407
b) The probability that at least one of them will like the football = 0.7672
a) If we select three students then the probability that exactly one of them will be a girl
From the attached two way table we can observe that the total number of girls = 22
the total number of boys = 18
and the total number of students = 40
The possible outcomes for selecting 3 students from 40 would be,
⁴⁰C₃
Using combination formula,
⁴⁰C₃ = 40! / (3! × (40 - 3)!)
= 9880
If there is exactly one girl then other two must be boys in the set of 3 selected students.
So, the required probability would be,
P = (²²C₁ × ¹⁸C₂) / ⁴⁰C₃
P = (22 × 153)/9880
P = 0.3407
b) The number of students like the football = 15
and the number of students who don't like the football are 40 - 15 = 25
The probability that at least one of them will like the football would be,
P = (¹⁵C₃ × ²⁵C₀ + ¹⁵C₂ × ²⁵C₁ + ¹⁵C₁ × ²⁵C₂) / ⁴⁰C₃
P = ((455 × 1) + (105 × 25) + (15 × 300)) / 9880
