To solve this problem, we first need to find the circumference of the bicycle tire. We know that the diameter of the tire is 18 inches, which means the radius is 9 inches (since radius = diameter/2). To find the circumference, we can use the formula C = 2πr, where π is pi (approximately 3.14).
C = 2π(9)
C = 18π
C ≈ 56.55 inches
Now we can use the circumference to find how far the bicycle travels in 22 revolutions. One revolution means the tire travels one circumference, so 22 revolutions means the tire travels 22 circumferences.
Distance traveled = 22 revolutions × 56.55 inches/revolution
Distance traveled ≈ 1244.1 inches
Finally, we need to convert inches to feet. There are 12 inches in a foot, so we can divide the distance traveled by 12 to get the answer in feet:
Distance traveled ≈ 103.67 feet (rounded to the nearest hundredth)
Therefore, when the bicycle wheel makes 22 revolutions, the bicycle travels approximately 103.67 feet.

The Doubling Coin, Part 1
Suppose that you have a coin whose value doubles every day. That is, on the day you
get the coin, Day 0, its value is $1. On Day 1, its value is $2. On Day 2, its value is $4,
and so on, doubling in value each additional day. How many days must you wait for the
coin to be worth $1.000.0002
1. Write a function we can use to model the value of the Doubling Coin. Justify the
type of function you selected for your model.
The function V(t) to represent the value of the coin at time t in days.
V(t) = \(2^t\)
To model the value of the Doubling Coin over time, we can use an exponential function.
The value of the coin doubles every day: This doubling pattern is best captured by an exponential function, where the base (2 in this case) represents the rate of growth.
Constant relative growth rate: In an exponential function, the rate of growth or decay is constant. In this case, the coin's value doubles consistently each day, indicating a constant relative growth rate.
Therefore, the function V(t) = \(2^t\) is an appropriate choice to model the value of the Doubling Coin over time.

Answer: -5x^3 -13x^2 -6x + 15ix + 39ix + 18i
Step-by-step explanation:
An equation with zeros at these numbers could be put in form x = number.
So, (x-3) could be set to 0 to get x=3.
So, you can look at these "answers" they give you and work backward to get:
(x-3)(x+2/5)(x-3i)
Multiply first two together.
x^2+2/5x-3x-6/5
simplify
x^2 - 2 3/5x -6/5
Change first term to have same denominator by multiplying by "1" in the form of -5/-5
-5x^2/-5 - 13/5x -6/5
Divide all terms by 1/5 (which is the same as multiplying each term by 5)

what two numbers add up to 55 and multiply to -375
Answer:
-6.13406 and 61.13406
Step-by-step explanation:
x + y = 55
x × y = -375
y = 55 - x
x × (55 - x) = -375
55x -x² = -375
x² - 55x - 375 = 0
solution of a quadratic equation :
x = (-b ± sqrt(b² - 4ac))/(2a)
a=1
b=-55

Q. 7. Evaluate the total electric charge on the solid bounded by the cone z=−sqrt(x^2+y^2) and the plane z=−2, given that the charge density σ is σ(x,y,z)=z2. (A) 7π/5 (B) 10π/3 (C) 32π/5 (D) 13π/2
The total electric charge on the solid bounded by the cone z=−sqrt(x^2+y^2) and the plane z=−2, given that the charge density σ is σ(x,y,z)=z2. we have the correct option A) 7π/5 is wrong and the answer to this problem is 4/3. Therefore, we conclude that the answer is 4/3.
The charge density σ is given by the equation σ(x,y,z)=z². The solid bounded by the cone z=−sqrt(x²+y²) and the plane z=−2 can be expressed in cylindrical coordinates by:r: 0 to 2θ: 0 to 2πz: -2 to -rThe total charge can be calculated as:Q = ∫∫∫ σ(x,y,z) dVQ = ∫0²∫0²∫-r⁻² z² r dz dθ drQ = ∫0²∫0² r (2-r²) dθ drQ = ∫0² 2r (2-r²) drQ = 4/3The total electric charge on the solid bounded by the cone z=−sqrt(x²+y²) and the plane z=−2 is 4/3. Therefore, the correct option is the letter A) 7π/5.**Explanation:** From the above explanation, we have the correct answer as 4/3 but the options given are not matching with the answer obtained. Therefore, let us solve again and obtain the correct answer.Integration is as follows,Q=∫∫∫ z² dx dy dz
Rearranging the equation of the cone, we have:z=−sqrt(x²+y²)So, x²+y² = z² .............(i)
In polar coordinates,x²+y² = r², so we can say r = zIn cylindrical coordinates,x = rcosθ and y = rsinθ
Substitute this into equation (i), r² = z²So, z = ± rWe can use the limits z=−r and z=−2 for our calculations.Thus, the integral becomes, Q=∫∫∫ z² dx dy dz=∫∫∫ r² × r dr dθ dzBy using limits, we get:0≤θ≤2π−2≤z≤−r≤r≤2Thus,Q=∫∫∫ r³ dr dθ dz=∫0² ∫0² ∫−r^(−2) r³ dz dθ dr=∫0² ∫0² −r⁵/5 dθ dr=∫0² 2π. (-2/15) dr=4/3
Finally, we have the correct option A) 7π/5 is wrong and the answer to this problem is 4/3. Therefore, we conclude that the answer is 4/3.

Find the particular function y given that dy dx = y(x) = 7√x - 3x√x + 6, when x = 1, y = 4 (Use symbolic notation and fractions where needed.)
Given differential equation is `dy/dx = y(x) = 7√x - 3x√x + 6` and the particular point is `(1,4)`To find the particular function y(x) that satisfies the given differential equation, we need to solve the differential equation with the help of integration.
Separate the variables and integrate both sides with respect to x.∫`1/y dy =` ∫`(7√x - 3x√x + 6) dx`Taking integral, we get: `ln|y| + C = 2(√x)^3 - 3(√x)^2 + 6x + C_1` Here, C and C1 are the constants of integration.
Combining both of them we get:C2 = C1 − C where
C2 = constant of integration
= `ln|y|` − `2(√x)^3 + 3(√x)^2 − 6x`
Putting x = 1 and y = 4, we get: `ln(4) - 2 + 3 - 6 = C_2`=> `
ln(4) - 5 = C_2`
So, the required particular function is: Putting the value of `C_2` back into the equation and then simplifying it Taking antilogarithm on both sides Therefore, the particular function is: `y = ± e^(2√x(x + 3) − 5)`

3. Consider the sequence,-8, -5, -2, 1, ...
a) Determine the explicit formula for the general term, 1,, of this sequence in simplified
form. (2 marks)
b) Use this formula to determine the value of t20. (1 mark)
c) Algebraically determine which term has a value of 40. (1 mark)
Answer:
a) \(a_n=3\,n-11\)
b) \(a_{20}=49\)
c) term number 17 is the one that gives a value of 40
Step-by-step explanation:
a)
The sequence seems to be arithmetic, and with common difference d = 3.
Notice that when you add 3 units to the first term (-80, you get :
-8 + 3 = -5
and then -5 + 3 = -2 which is the third term.
Then, we can use the general form for the nth term of an arithmetic sequence to find its simplified form:
\(a_n=a_1+(n-1)\,d\)
That in our case would give:
\(a_n=-8+(n-1)\,(3)\\a_n=-8+3\,n-3\\a_n=3n-11\)
b)
Therefore, the term number 20 can be calculated from it:
\(a_{20}=3\,(20)-11=60-11=49\)
c) in order to find which term renders 20, we use the general form we found in step a):
\(a_n=3\,n-11\\40=3\,n-11\\40+11=3\,n\\51=3\,n\\n=\frac{51}{3} =17\)
so term number 17 is the one that renders a value of 40

The standard length of a piece of cloth for a bridal gown is 3.25 meters. A customer selected 35 pcs of cloth for this purpose. A mean of 3.52 meters was obtained with a variance of 0.27 m2 . Are these pieces of cloth beyond the standard at 0.05 level of significance? Assume the lengths are approximately normally distributed
The pieces of cloth are beyond the standard at 0.05 level of significance.
We can use a one-sample t-test to determine if the mean length of the 35 pieces of cloth is significantly different from the standard length of 3.25 meters.
The null hypothesis is that the mean length of the cloth pieces is equal to the standard length:
H0: μ = 3.25
The alternative hypothesis is that the mean length of the cloth pieces is greater than the standard length:
Ha: μ > 3.25
We can calculate the test statistic as:
t = (x - μ) / (s / √n)
where x is the sample mean length, μ is the population mean length (3.25 meters), s is the sample standard deviation (0.52 meters), and n is the sample size (35).
Plugging in the values, we get:
t = (3.52 - 3.25) / (0.52 / √35) = 3.81
Using a t-table with 34 degrees of freedom (n-1), and a significance level of 0.05 (one-tailed test), the critical t-value is 1.690.
Since our calculated t-value (3.81) is greater than the critical t-value (1.690), we reject the null hypothesis and conclude that the mean length of the 35 pieces of cloth is significantly greater than the standard length at the 0.05 level of significance.

Find an equation for the line perpendicular to the tangent to the curve y=x3−4x+1 at the point (2,1).
The equation of the line perpendicular to the tangent to the curve y=x^3-4x+1 at the point (2,1) is y = (-1/8)x + 9/8.
To find the equation of the line perpendicular to the tangent to the curve at (2,1), we need to first find the slope of the tangent line at that point.
The derivative of y=x^3-4x+1 is y'=3x^2-4, so the slope of the tangent line at (2,1) is y'(2) = 3(2)^2-4 = 8.
Since we want the line perpendicular to the tangent, we know that its slope will be the negative reciprocal of the tangent's slope. Therefore, the slope of the line we're looking for is -1/8.
Next, we use the point-slope form of the equation of a line to write the equation of the line with the slope we found and passing through the point (2,1):
y - 1 = (-1/8)(x - 2)
Simplifying and putting the equation in slope-intercept form:
y = (-1/8)x + 9/8
Therefore, the equation of the line perpendicular to the tangent to the curve y=x^3-4x+1 at the point (2,1) is y = (-1/8)x + 9/8.

The width of a rectangle varies inversely with the length of the rectangle. The width is 4 and the length is 12. Write the inverse variation equation to match this scenario:
This equation implies that as the length of the rectangle increases, the width decreases, and vice versa. the width of the rectangle varies inversely with its length, and the constant of variation is 48.
To write the inverse variation equation for this scenario, we need to identify the constant of variation. In an inverse variation, the product of the width and length is always constant.
Given that the width (w) is 4 and the length (L) is 12, we can write the equation as follows:
w * L = k
Plugging in the values, we get:
4 * 12 = k
48 = k
So, the constant of variation (k) is 48.
Now, we can write the inverse variation equation:
w * L = 48
The inverse variation equation for this scenario is w * L = 48. This equation implies that as the length of the rectangle increases, the width decreases, and vice versa. In conclusion, the width of the rectangle varies inversely with its length, and the constant of variation is 48.
