a. If t represents time in hours and d represents distance in miles, and Caden walks at a steady rate of 3.6 miles per hour, the equation that models the relationship between these variables is:

d = 3.6t

b. To calculate the distance Caden will walk in 3/4 of an hour, plug 3/4 into the equation for t:

d = 3.6(3/4) = 2.7 miles

Caden will walk 2.7 miles in 3/4 of an hour.

c. To calculate how long it will take for Caden to walk 4.32 miles, plug 4.32 into the equation for d and solve for t:

4.32 = 3.6t
t = 4.32/3.6 ≈ 1.2 hours

It will take Caden approximately 1.2 hours to walk 4.32 miles.

The dimensions of the package of largest volume are 18 inches by 18 inches by 36 inches. The largest possible volume is 11664 cubic inches.

To find the dimensions of the package of largest volume. Let the dimensions of the square end be x, and the length of the rectangular end be y. The girth of the package is 4x, and the length is y. According to the problem statement, the girth plus length may not exceed 108 inches, so we have:

We want to maximize the volume V(x,y) of the package, which is given by:

We can use the equation 4x + y = 108 to express y in terms of x:

Substituting this into the formula for V(x,y), we get:

The domain of V(x) is determined by the constraints that x and y must be positive and the girth plus length may not exceed 10 inches. Since the girth is 4x, we have:

Solving for x, we get:

Since x must be positive, the domain of V(x) is:

The maximum volume and the optimal dimensions

To find the absolute maximum of V(x) on the domain 0 < x ≤ 32/3, we take the derivative of V(x) with respect to x and set it equal to zero:

[tex]V'(x) = 216x - 12x^2 = 0[/tex]

Solving for x, we get:

To confirm that this is a maximum, we take the second derivative of V(x) with respect to x:

At x = 18, we have V''(18) = 0, which means that the second derivative test is inconclusive. However, we can see that V(x) is increasing on the interval 0 < x < 18 and decreasing on the interval 18 < x ≤ 32/3, which means that x = 18 is indeed the absolute maximum of V(x) on the domain.

The prime number values of a, b and c that satisfy the equation a⁴ + b⁴ + c⁴ + 54 = 11abc are a = 3, b = 2, and c = 5.

Let's consider the equation a⁴ + b⁴ + c⁴ + 54 = 11abc. Due to the fact that the total of four even numbers is also even, the left-hand side is always even. As a result, since 2 is the only even prime, one of the factors a, b, or c must be 2 for 11abc to likewise be even.

Let's examine each instance,

Case 1: a = 2

Substituting a = 2 into the equation, we get,

16 + b⁴ + c⁴ + 54 = 22bc

b⁴ + c⁴ - 22bc + 38 = 0

Since b and c are primes, they must be odd. Let b = 3 and c = 5, we have,

3⁴ + 5⁴ - 2235 + 38 = 0

81 + 625 - 330 + 38 = 0

Case 2: b = 2

Substituting b = 2 into the equation, we get,

a⁴ + 16 + c⁴ + 54 = 22ac

a⁴ + c⁴ - 22ac + 70 = 0

Since a and c are primes, they must be odd. Let a = 3 and c = 5, we have,

3⁴ + 5⁴ - 2235 + 70 = 0

Case 3: c = 2

Substituting c = 2 into the equation, we get,

a⁴ + b⁴ + 16 + 54 = 22ab

a⁴ + b⁴ - 22ab + 70 = 0

However, for any odd number x, x⁴ mod 16 = 1, which means that a⁴ and b⁴ are both corrosponds to 1 mod 16. So, as the conclusion, a = 3, b = 2, and c = 5.

Ben could have saved $0.15 per gallon if he had gone to the gas station across the street.

If Ben filled his 20-gallon tank of gas with regular fuel for $59.80, then the cost per gallon can be found by dividing the total cost by the number of gallons:

cost per gallon = total cost / number of gallons

cost per gallon = $59.80 / 20 gallons

cost per gallon = $2.99/gallon

If the gas station across the street sold regular fuel for $2.84 a gallon, then the amount Ben could have saved per gallon is:

savings per gallon = cost per gallon at initial station - cost per gallon at other station

savings per gallon = $2.99/gallon - $2.84/gallon

savings per gallon = $0.15/gallon

One specific example of a rule for the function f such that the series Σα) f(n)/n^2 does not converge is the function f(n) = (-1)^n.

To justify this, we can use the alternating series test, which states that if a series has alternating signs and the absolute values of its terms decrease monotonically to 0, then the series converges. However, if the absolute values of its terms do not decrease monotonically to 0, then the series diverges.

In this case, we have Σα) f(n)/n^2 = Σα) (-1)^n/n^2. The absolute value of each term is 1/n^2, which does decrease monotonically to 0. However, the signs of the terms alternate, meaning that the series does not converge.

The difference between the volume of the sphere and the volume of the cone is approximately 838.81 cubic inches.

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius. Thus, for a sphere with a radius of 6 inches, the volume is:

V_sphere = (4/3)π(6³) = 904.78 cubic inches

The volume of a cone is given by the formula V = (1/3)πr[tex]^{2h}[/tex], where r is the radius and h is the height. Thus, for a cone with a radius of 3 inches and a height of 7 inches, the volume is:

V_cone = (1/3)π(3²)(7) = 65.97 cubic inches

Therefore, the difference between the volume of the sphere and the volume of the cone is:

V_sphere - V_cone = 904.78 - 65.97 = 838.81 cubic inches

To find the percentage of students who collected between 49 and 98 kilograms of newspapers, we need to first count the number of students whose collection falls within this range. We can do this by sorting the data and counting the number of values that fall within this range.

Sorting the data, we get:

15, 23, 35, 45, 45, 49, 55, 56, 57, 60, 64, 75, 76, 87, 88, 90, 98, 100, 101, 105, 120, 122

We can see that there are 17 students whose collection falls within the range of 49 to 98 kilograms.

To find the percentage of students, we can divide the number of students whose collection falls within this range by the total number of students and then multiply by 100. The total number of students is the sum of the number of values in the two sets, which is 22 + 22 = 44.

The probability of TJ pulling 2 white socks is 0.125 or 12.5%.

There are 16 socks in total, so the probability of the first sock being white is 6/16.

Since we are not replacing the first sock, there are now 15 socks left, including 5 white socks.

So the probability of the second sock being white, given that the first sock was white, is 5/15.

To find the probability of both events occurring, we multiply the probabilities:

P(white and white) = P(white on first draw) × P(white on second draw, given that the first was white)

P(white and white) = (6/16) × (5/15)

P(white and white) = 1/8

The divergence of F is 2y cos(z) + eˣ cos(z) + 3xe³, and the curl of F is -eˣcos(z)i - 3xe³j + (eˣsin(z) + 2cos(z))k.

To find the divergence and curl of the vector field F(x, y, z) = 2y cos(z)i + eˣ sin(z)j + xe³k, we need to apply the appropriate operators.

The divergence of F is given by:

div F = ∇ · F = (∂/∂x)i + (∂/∂y)j + (∂/∂z)k · (2y cos(z)i + eˣ sin(z)j + xe³k)

where ∇ is the del operator.

Calculating the dot product, we get:

div F = 2y cos(z) + eˣ cos(z) + 3xe³

Therefore, the divergence of F is:

div F = 2y cos(z) + eˣ cos(z) + 3xe³

Now, let's find the curl of F. The curl of F is given by:

curl F = ∇ × F = ( (∂/∂y)(xe³) - (∂/∂z)(eˣsin(z)) )i - ( (∂/∂x)(2ycos(z)) - (∂/∂z)(xe³) )j + ( (∂/∂x)(eˣsin(z)) - (∂/∂y)(2ycos(z)) )k

Calculating the partial derivatives, we get:

(∂/∂y)(xe³) = 0

(∂/∂z)(eˣsin(z)) = eˣcos(z)

(∂/∂x)(2ycos(z)) = 0

(∂/∂z)(xe³) = 3xe³

(∂/∂x)(eˣsin(z)) = eˣsin(z)

(∂/∂y)(2ycos(z)) = -2cos(z)

Substituting these values, we get:

curl F = (0 - eˣcos(z))i - (0 - 3xe³)j + (eˣsin(z) - (-2cos(z)))k

Simplifying, we get:

curl F = -eˣcos(z)i - 3xe³j + (eˣsin(z) + 2cos(z))k

Therefore, the divergence of F is 2y cos(z) + eˣ cos(z) + 3xe³, and the curl of F is -eˣcos(z)i - 3xe³j + (eˣsin(z) + 2cos(z))k.

The expression equation y = sin x + cos x / csc x can be simplified to y = cos x sin^2 x + cos^2 x.

To simplify the expression, we can first replace csc x with 1/sin x. This gives us y = sin x cos x + cos^2 x / sin x.

Next, we can factor out cos x from the numerator of the second term to get y = cos x (sin x + cos x) / sin x.

Using the identity sin^2 x + cos^2 x = 1, we can replace sin^2 x with 1 - cos^2 x in the numerator of the first term. This gives us y = cos x (1 - cos^2 x) / sin x + cos x (sin x + cos x) / sin x.

Simplifying the expression further, we get y = cos x (1 - cos^2 x + sin x + cos x) / sin x.

Finally, we can combine the terms in the numerator to get y = cos x (sin^2 x + 2cos x sin x + 1) / sin x.

Using the identity sin^2 x = 1 - cos^2 x, we get y = cos x (3cos^2 x + 2cos x) / sin x.

Simplifying the expression, we arrive at y = cos x (cos x + 2) (3cos x + 2) / sin x.

Therefore, the simplified expression is y = cos x sin^2 x + cos^2 x, which can also be written as y = cos x (sin x)^2 + cos^2 x.

To find an expression for the position s after a time t, we need to integrate the velocity function v with respect to time t.

Using the power rule of integration and the constant of integration C, we have:

s = ∫v dt = ∫[t(t² + 1)³ + 3t] dt

after expanding t(t² + 1)³ using binomial theorem we have-

(t^2 + 1)³ = t⁶ + 3t⁴ + 3t² + 1

Substituting this into the integral, we get:

s = ∫[t(t⁶ + 3t⁴ + 3t^2 + 1) + 3t] dt

s = ∫[t^7 + 3t⁵ + 3t³ + t + 3t] dt

s = ∫t^7 dt + 3∫t⁵ dt + 3∫t³ dt + ∫4t dt

s = (1/8)t⁸ + (3/6)t⁶ + (3/4)t⁴ + 2t² + C

We have an equation, 4x + 8y = 20 --(1) which is linear equation with two variables. We have to determine the the x- and y-intercepts of the graph of equation (1). The graph of line (1) is present in above figure. Slope intercept form of equation (1) is written as [tex]y = - \frac{1}{2}x + \frac{5}{2}[/tex],

As we know, two points determine any line, we can graph lines using the x- and y-intercepts. To determine the x-intercept, we substitute y=0 and solve for x. So, when y = 0 then 4x + 0 = 20

=> x = 5

similarly to determine the y-intercept, set x=0 and solve for y. When x = 0

(1) it takes about 10 hours to thaw a 20-pound turkey in cold water.(2) it takes an additional 0.25 hours (or 15 minutes) to thaw in the refrigerator.

A linear function is a function that represents a straight line in the coordinate plane. For example, y = 3x - 2 represents a straight line in the coordinate plane and thus a linear function. Since y can be replaced by the function f(x), this function can be written as f(x) = 3x - 2.

 a. A typical thawing rate when thawing in the refrigerator  is about 1 day per 4-5 kilograms of turkey meat. So if you have a 20 pound turkey, it will take about 4-5 days to thaw in the fridge. In cold water, the thawing rate  is about 30 minutes per pound, so it takes about 10 hours to thaw a 20-pound turkey in cold water.

b) The initial value may represent the weight of the frozen turkey before thawing begins. c. Let y be the time it takes to thaw the turkey in hours and let x be the weight of the turkey in pounds. Assuming a linear relationship between melting time and weight, we can write:

y = mx + b

where m is the thaw rate (in hours per pound) and b is the intercept (the time it takes to thaw a 0-pound turkey, which is 0). From part a, we know that the refrigerator thaw rate  is about 1 day per 4-5 pounds of turkey, or about 0.25-0.2 hours per pound. So we can use m = 0.25 in our linear function:

y = 0.25x + 0

This means that for every additional pound of turkey, it takes an additional 0.25 hours (or 15 minutes) to thaw in the refrigerator.

To the nearest tenth of an inch, the length of the shorter leg of each right triangle will be 2.7 inches.

A triangle is a polygon with three sides and three angles. The sum of the three angles in a triangle always adds up to 180 degrees.

Let x be the length of the shorter leg of each right triangle. Then, the longer leg will be twice as long, so its length will be 2x. Using the Pythagorean theorem, we can write:

x² + (2x)² = 6²
