Answer:Archer's speed is 60 mph.

Sassoon's speed is 40 mph.

Step-by-step explanation:

Let the distance that Sassoon travels is d miles.

Let his average speed be x mph.

The time of travel is from 1 p.m. to 4 p.m., which is 3 hours.

Therefore

3x = d                            (1)

The distance that Archer travels is (d + 300) miles.

The time of travel is from 9 a.m. to 4 p.m., which is 7 hours.

The average traveling speed is (x + 20) mph, therefore

7(x + 20) = d + 300    

That is,

7x + 140 = d + 300

7x = d + 160                  (2)

Subtract (1) from (2).

7x - 3x = d + 160 - d

4x = 160

x = 40 mph  (Sassoon's average speed)

x+20 = 60 mph (Archer's average speed)

From (1), obtain d = 120 mi

Answer:

Archer's speed is 60 mph.

Sassoon's speed is 40 mph.

To express 0.63¯¯¯¯ as a fraction, first set it up as x = 0.6363¯¯¯¯, then follow a process of subtraction, multiplication, and division to simplify it to 4063/9900.

To express 0.63¯¯¯¯ as a fraction in simplest form, we can set it up as x = 0.6363¯¯¯¯.

Combining these steps, we get:

99x = 3.606363¯¯¯¯¯¯¯¯ x = 3.606363¯¯¯¯ / 99 = 4063/9900 as the fraction in simplest form.

To find the consecutive even integers, we created an equation and solved for x, which represents the smallest integer. Upon solving, we found that the smallest integer is 6, and hence, the three consecutive even integers are 6, 8, and 10.

To find three consecutive even integers such that the sum of twice the smallest number and three times the largest is 42, we can form an equation based on the description. Let the smallest even integer be x. Since we are looking for consecutive even integers, the next two will be x+2 and x+4.

According to the problem, twice the smallest plus three times the largest equals 42:

2x + 3(x+4) = 42

Solving the equation:

Distribute the 3 into the parentheses: 2x + 3x + 12 = 42

Combine like terms: 5x + 12 = 42

Subtract 12 from both sides: 5x = 30

Divide both sides by 5: x = 6

Therefore, the smallest even integer is 6, and the other two are 8 and 10, which are the consecutive even integers that satisfy the given condition.

Answer:

d = 465 - 60x

Step-by-step explanation:

1. Find the distances of walking and bicycling. We can express the walking distance as 33x, because x is the time and 33 is the amount of miles, and we can express the bicycling distance as 93(5-x), because 93 is the speed and 5-x is the amount of hours.

2. Construct an equation. We can say that the total distance is d = 33x + 93(5-x), the sum of both of the distances.

3. Simplify. If you simplify, you would get d = 465 - 60x

Answer: d = 465 - 60x

the values of [tex]\( a \)[/tex] and [tex]\( b \)[/tex] are 8 and [tex]\( 2\sqrt{7} \)[/tex], respectively.

The image depicts a right-angled triangle with a hypotenuse of length 10 and one leg of length 6, with the other leg labeled as [tex]\( a \)[/tex]. There is also a smaller right-angled triangle within it, sharing the leg of length 6 with the larger triangle, with the hypotenuse of the smaller triangle labeled as 8 and the other leg labeled as [tex]\( b \).[/tex]

To find the lengths of [tex]\( a \)[/tex] and [tex]\( b \)[/tex], we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse [tex](\( c \))[/tex] is equal to the sum of the squares of the lengths of the other two sides [tex](\( a \)[/tex] and [tex]\( b \)[/tex]): [tex]\( c^2 = a^2 + b^2 \).[/tex]

For the larger triangle:

[tex]\[ 10^2 = 6^2 + a^2 \][/tex]

For the smaller triangle:

[tex]\[ 8^2 = 6^2 + b^2 \][/tex]

We will solve these two equations to find [tex]\( a \)[/tex] and [tex]\( b \)[/tex]. Let's start with the calculations for [tex]\( a \)[/tex] and [tex]\( b \)[/tex] using the Pythagorean theorem.

Using the Pythagorean theorem for each triangle, we find:

For the larger triangle:

[tex]\[ a^2 = 10^2 - 6^2 \][/tex]

[tex]\[ a^2 = 100 - 36 \][/tex]

[tex]\[ a^2 = 64 \][/tex]

[tex]\[ a = 8 \][/tex]

For the smaller triangle:

[tex]\[ b^2 = 8^2 - 6^2 \][/tex]

[tex]\[ b^2 = 64 - 36 \][/tex]

[tex]\[ b^2 = 28 \][/tex]

[tex]\[ b = \sqrt{28} \][/tex]

[tex]\[ b = 2\sqrt{7} \][/tex]

So, the values of [tex]\( a \)[/tex] and [tex]\( b \)[/tex] are 8 and [tex]\( 2\sqrt{7} \)[/tex], respectively.

The graph of the equation y = 1/3x - 4 is a straight line that contains the points (3, -3) and (0, 04)

The bottom left is the correct answer.

We have,

To graph this equation, we can start by finding the y-intercept, which is the point where the line crosses the y-axis.

In this equation,

The y-intercept is -4, so we plot the point (0, -4).

Next, we can find another point on the line by choosing a value for x and calculating the corresponding y-value.

Let's choose x = 3.

Plugging this value into the equation, we get:

y = (1/3)(3) - 4

y = 1 - 4

y = -3

So point (3, -3) lies on the line.

Now we can plot these two points (0, -4) and (3, -3) and draw a straight line passing through them.

Since the coefficient of x is positive (1/3), the line will have a positive slope, meaning it rises as we move from left to right.

Thus,

The graph of the equation y = 1/3x - 4 would look like a straight line that slants upward as you move from left to right, crossing the y-axis at -4.

To evaluate the line integral, we need to parameterize the line segment and calculate the differential arc length. After simplifying the integrand, we can evaluate the line integral by integrating the simplified expression.

To evaluate the line integral ∫cx^4zds, where c is the line segment from (0,6,5) to (8,4,1), we need to parameterize the line segment c. Let's parameterize it with t, where t varies from 0 to 1. The parameterization of c is given by:

x(t) = 8t, y(t) = 6 - 2t, z(t) = 5 - 4t.

Next, we need to calculate ds, which is the differential arc length along the line. The differential arc length ds is given by:

ds = √(dx/dt)^2 + (dy/dt)^2 + (dz/dt)^2 dt.

Substituting the parameterized values of x(t), y(t), and z(t) into the above equation, we get:

ds = √[(8)^2 + (-2)^2 + (-4)^2] dt = √84 dt.

Now, we can rewrite the line integral as:

∫cx^4zds = ∫(8t)^4(5 - 4t)√84 dt.

Next, we simplify the integrand:

(8t)^4(5 - 4t) = 4096t^4(5 - 4t).

Finally, we evaluate the line integral by integrating the simplified integrand over the interval [0, 1]:

∫(8t)^4(5 - 4t)√84 dt = √84 ∫4096t^4(5 - 4t) dt.

The distributive property is demonstrated in the equation.

The algebraic property demonstrated in the equation is the distributive property. The distributive property states that when a number is multiplied by the sum or difference of two other numbers, you can distribute the multiplication to each term inside the parentheses.

In the given equation, 3(2x - 7) means multiplying 3 by both terms inside the parentheses. This results in 6x - 21. Therefore, the equation can be simplified to 5 + 6x - 21.

To determine the length of the curve, we find the derivative of the given vector function, compute its magnitude, and then compute the integral of the magnitude from 0 to 1. This involves calculus techniques.

To find the length of the curve, we have to compute the integral of the magnitude of the derivative on the interval from 0 to 1. First, we find the derivative of r(t) = 3 i + t^2 j + t^3 k which is r'(t) = 2t j + 3t^2 k. The magnitude of r'(t) is |r'(t)| = sqrt((0)^2 + (2t)^2 + (3t^2)^2) = sqrt(4t^2 + 9t^4). Thus the length of the curve is the integral of this magnitude from 0 to 1: ∫ from 0 to 1 of sqrt(4t^2 + 9t^4) dt. This integral can be evaluated using techniques from calculus.

To find the number of miles Mr. Lee drove the moving truck, we can set up an equation using the given information and solve for 'm'. The equation is $250 + $0.40x = $314, where 'x' represents the number of miles driven. Simplifying the equation, we find that Mr. Lee drove a total of 160 miles in the moving truck.

To find the number of miles Mr. Lee drove the moving truck, we can set up an equation using the given information. The moving company charges $250 to rent the truck and $0.40 for each mile driven. Let's let 'm' represent the number of miles he drove. The total cost Mr. Lee paid, including the rental fee and the cost per mile, is $314. So, the equation can be written as:

$250 + $0.40x = $314

To solve for 'm', we can subtract $250 from both sides of the equation:

$0.40x = $314 - $250

$0.40x = $64

Finally, we can divide both sides of the equation by $0.40 to find the value of 'm':

x = $64 / $0.40

x = 160

Therefore, Mr. Lee drove a total of 160 miles in the moving truck.
