Tyler drove 138miles, and brittney drove 116miles, the ratio of tyler's miles to brittney's miles is 69/58.

The ratio of Tyler's miles to Brittney's miles can be found by dividing Tyler's miles by Brittney's miles.

Ratio of Tyler's miles to Brittney's miles = Tyler's miles / Brittney's miles

Ratio of Tyler's miles to Brittney's miles = 138 miles / 116 miles

Simplifying the ratio by dividing both numbers by their greatest common factor, which is 2, we get:

Hence,

Ratio of Tyler's miles to Brittney's miles = 69/58

This means that for every 69 miles Tyler drove, Brittney drove 58 miles.

Her sales in order to earn at least $29,000 this year must be at least 60000

From the question, we have the following parameters that can be used in our computation:

Using the above as a guide, we have the following:

Earnings = 20000 + 15% * x

Where x is sales

The earnings is atleast 29,000

So, we have

20000 + 15% * x ≥ 29,000

This gives

15% * x ≥ 9,000

So, we have

x ≥ 60000

Hence, her sales must be at least 60000

Step-by-step explanation:

The angles given are complementary angles ( 90°).

25°+∠x=90°

∠x=65°

the height of the lamp-post is approximately 2.02 meters.

To find the height of the lamp-post, we can use the properties of a right-angled triangle.

Given that the lamp-post is at the midpoint D of AC and subtends an angle of 30° at B, we can draw a perpendicular line from D to AB, creating a right-angled triangle ABD.

Let's denote the height of the lamp-post as h.

In triangle ABD, we have the following:

AB = 7 m (given)

BD = AB/2 = 7/2 = 3.5 m (since D is the midpoint of AC)

∠BAD = 30° (given)

Using trigonometric ratios, we can find the height h.

We know that the tangent of an angle is equal to the ratio of the opposite side to the adjacent side.

tan(∠BAD) = h / BD

tan(30°) = h / 3.5

1/√3 = h / 3.5

Cross-multiplying, we get:

h = (1/√3) * 3.5

h ≈ 2.02 m

Therefore, the height of the lamp-post is approximately 2.02 meters.

a) To evaluate the integral ∭f(x²y + 3xyz) dxdydz over the region G, we will apply the given transformation u = x, v = xy, and w = 3z.

The Jacobian matrix of the transformation is:

J = {{∂u/∂x, ∂u/∂y, ∂u/∂z},

{∂v/∂x, ∂v/∂y, ∂v/∂z},

{∂w/∂x, ∂w/∂y, ∂w/∂z}}

Calculating the partial derivatives, we have:

J = {{1, 0, 0},

{y, x, 0},

{0, 0, 3}}

The absolute value of the determinant of the Jacobian matrix is |J| = 3x.

Now we need to express the integral in terms of the new variables:

∭f(x²y + 3xyz) dxdydz = ∭f(u²v + 3uvw) |J| dudvdw.

The new limits of integration are obtained by transforming the limits of the region G:

1 ≤ x ≤ 2 --> 1 ≤ u ≤ 2

0 ≤ xy ≤ 2 --> 0 ≤ v ≤ 2

0 ≤ z ≤ 1 --> 0 ≤ w ≤ 3.

Substituting all the values, the integral becomes:

∭f(u²v + 3uvw) |J| dudvdw = ∭f(u²v + 3uvw) (3x) dudvdw.

Using Mathematica or any other software, you can compute this integralover the new region with the given expression. The result will depend on the specific function f(x, y, z).

b) To evaluate the integral [xy dx + (x+y)dy] along the curve y = x² from (-1,1) to (2,4), we parameterize the curve as follows:

r(t) = ti + t²j, where -1 ≤ t ≤ 2.

The integral becomes:

∫[xy dx + (x+y)dy] = ∫[xt dx + (x+x²)dy].

Now we substitute x = t and y = t² into the integrand:

∫[xt dx + (x+x²)dy] = ∫[t(t) dt + (t+t²)(2t) dt] from -1 to 2.

Simplifying, we have:

∫[xt dx + (x+x²)dy] = ∫[(t² + 2t³) dt] from -1 to 2.

Evaluate this integral using Mathematica or any other software to obtain the result.

c) To evaluate the integral √√(x² + y²) ds along the curve r(t) = (4cost)i + (4sint)j + 3tk, -27 ≤ t ≤ 27, we need to find the derivative of the curve and calculate the magnitude.

The derivative of r(t) is:r'(t) = (-4sint)i + (4cost)j + 3k.

The magnitude of r'(t) is:

|r'(t)| = √((-4sint)² + (4cost)² + 3²) = √(16sin²t + 16cos²t + 9) = √(25) = 5.

Now, we evaluate the integral:

∫√√(x² + y²) ds = ∫√√(x² + y²) |r'(t)| dt from -27 to 27.

Substitute x = 4cost, y = 4sint, and ds = |r'(t)| dt into the integrand:

∫√√(x² + y²) ds = ∫√√(16cos²t + 16sin²t) (5) dt from -27 to 27.

Simplify and evaluate this integral using Mathematica or any other software.

d) To integrate f(x, y, z) = -√√(x² + z²) over the circle r(t) = (acost)j + (asint)k, 0 ≤ t ≤ 27, we need to parameterize the circle.

The parameterization is:

x = 0

y = acos(t)

z = asin(t)

The integral becomes:

∫f(x, y, z) ds = ∫-√√(x² + z²) |r'(t)| dt from 0 to 27.

Substitute x = 0, y = acos(t), z = asin(t), and ds = |r'(t)| dt into the integrand:

∫-√√(x² + z²) ds = ∫-√√(0² + (asint)²) |r'(t)| dt from 0 to 27.

It will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

To find the number of days it will take for $9500 to earn $800 at an annual interest rate of 8.25%, we need to use the formula for simple interest:

Interest = Principal * Rate * Time

In this case, we are given the interest ($800), the principal ($9500), and the annual interest rate (8.25%). We need to solve for time.

Let's denote the time in years as "t". Since we're looking for the number of days, we'll convert the time to a fraction of a year by dividing by 365 (assuming a standard 365-day year).

$800 = $9500 * 0.0825 * (t / 365)

Simplifying the equation:

800 = 9500 * 0.0825 * (t / 365)

Divide both sides by (9500 * 0.0825):

800 / (9500 * 0.0825) = t / 365

Simplify the left side:

800 / (9500 * 0.0825) ≈ 0.1083

Now, solve for t by multiplying both sides by 365:

0.1083 * 365 ≈ t

t ≈ 39.532

Therefore, it will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

To find the length of the hypotenuse (c) in a right triangle with an angle A of 34 degrees and a side length b of 22m, we can use the trigonometric function cosine.

By applying the cosine rule, we can determine c to be approximately 25.32m.

In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side length to the hypotenuse. Applying this concept to our triangle, we have cos(A) = b/c. Rearranging the equation, we get c = b / cos(A). Plugging in the values, c = 22 / cos(34°). By evaluating the cosine of 34 degrees (0.829), we can calculate c to be approximately 25.32 meters, rounded to the nearest hundredth. Thus, the length of the hypotenuse (c) in this right triangle is approximately 25.32 meters.

Al-Fatihah is an Islamic prayer recited during the five daily prayers. Comparing radio and television in reading Al-Fatihah from its beginning requires an analysis of how each medium conveys the prayer to its audience. Radio precedes television in reading Al-Fatihah from its beginning.

This is because radio broadcasting began in the early 1900s while television broadcasting began in the late 1940s.

This delay can range from a few seconds to a few minutes depending on several factors such as the geographical location of the audience, the strength of the signal, and the quality of the receiver. Therefore, the time difference between radio and television in reading Al-Fatihah can vary depending on the factors mentioned above.

Mathematically, the time difference between radio and television can be calculated using the formula: d = s / tWhere d is the distance between the transmitter and the receiver, s is the speed of the signal, and t is the time it takes for the signal to reach the receiver.

In this case, d is the distance between the broadcasting station and the audience, s is the speed of the signal which is constant (i.e., the speed of light), and t is the time it takes for the signal to reach the audience. Since the speed of light is approximately 299,792,458 m/s, the time it takes for the signal to reach the audience can be calculated using the following formula:t = d / s

Therefore, the time difference between radio and television in reading Al-Fatihah can be calculated by subtracting the time it takes for the radio signal to reach its audience from the time it takes for the television signal to reach its audience. This difference can range from a few milliseconds to a few minutes depending on the factors mentioned above.

In network concepts, the time difference between radio and television in reading Al-Fatihah can be affected by the bandwidth of the network. The bandwidth is the amount of data that can be transmitted over a network in a given time. If the bandwidth is low, it can cause a delay in the transmission of the signal which can affect the time difference between radio and television.
