HELP. It’s LOG form. Since were out of school I forgot how I did this and it’s due so it would be a life saver.

The polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. Here are two key characteristics of the polar coordinate system:

1. Radial Distance (Radius): In the polar coordinate system, the location of a point is determined first by its distance from a fixed point, called the pole, analogous to the origin in the Cartesian coordinate system. This distance is often denoted as \( r \), and it can be thought of as the radius of a circle centered at the pole, with the point lying on the circumference of this circle.

2. Angular Coordinate (Angle): The second characteristic of a point's location in the polar coordinate system is the angle [tex]\( \theta \)[/tex] (theta), which is measured from a fixed direction, typically the positive x-axis of the corresponding Cartesian coordinate system. This angle, usually measured in degrees or radians, determines the direction of the line from the pole to the point.

These two values, [tex]\( r \)[/tex] and [tex]\( \theta \)[/tex], are called polar coordinates, and they provide an alternative to the Cartesian (rectangular) coordinate system for representing points on a plane, particularly useful in scenarios where the geometry or the nature of the problem is radially symmetric, such as in the cases of circular motion or fields (gravitational, electric, etc.).

Answer:

slow hiker rate= 1.1mph and fast hiker rate= 5.5 mph

Step-by-step explanation:

lets consider the Speed of the slow hiker =x

Then Speed of fast hiker =x+4.4

As we know that distance is the product of speed and time

therefore,

Distance covered by slow hiker in 5 hours = 5x km

Distance covered by fast hiker in 5 hours=5 (x+4.4)=5x+22 km

As they are are 33 miles apart , therefore

5x + 5x+22 = 33

10x = 33-22

10x = 11

x =11/10 => 1.1

Rate of slow hiker is x i.e 1.1mph

Rate of fast hiker = x+4.4 => 5.5 mph

Answer:

slower hiker's speed = 1.1 mph

faster hiker's speed = 5.5 mph

Step-by-step explanation:

Extracting the key information from the question:

*** Two hikers are 33 miles apart and are walking towards each other.

*** One of them walks 4.4 mph faster than the other and later met themselves in 5 hours.

*** We are required to find the speed of each of the hikers.

  Speed = distance/time

 Let us use "x" to represent the slower speed. Since one of the hikers was 4.4 mph faster than the other hiker, we can represent the faster speed with x+4. Now, if they met themselves in 5 hours, even though they were 33 miles apart initially, then we can represent the situation with the given equation:-

  (x mph × 5hours) + [(x+4.4)×5] = 33 miles

5x  +  (5x + 22) = 33

5x + 5x + 22= 33

10x + 22 = 33

 10x = 33-22

  10x = 11

    x = 11/10

    x = 1.1mph (speed of slower hiker)

 The speed of the faster hiker = x + 4.4

 = 1.1 + 4.5

 = 5.5mph

Answer:

240 people

Step-by-step explanation:

According to the given data,

In each bus,there are total number of 36 students and 4 adults

So, total 40 people are in one bus so...

As, there are six Fields buses

=>40 x 6

=240

Answer: Total 240 people are going on the field trip.

To calculate the total number of people going on the field trip, multiply the number of students and adults by the number of buses and sum the result, resulting in 240 people.

The question relates to the calculation of the total number of people going on a field trip with a given number of students and adults per bus and a total number of buses. To find out how many people in total are going on the field trip, we need to multiply the number of students and adults by the number of buses and add up the results.

Each bus holds 36 students and 4 adults. With 6 buses on the field trip, we calculate the total number of people by multiplying the number of buses by the total capacity per bus (students plus adults): (36 students + 4 adults) × 6 buses.

So, the calculation is as follows:

40 people per bus × 6 buses = 240 people going on the field trip.

Answer:

L = 9

Step-by-step explanation:

Translating this into symbols, we get L = W + 1 and A = 72 = W * L.

Substituting W + 1 for L in the latter equation, we get:

72 = W(W + 1), or:

W^2 + 1W - 72 = 0

This factors into (W + 9)(W - 8) = 0, so that W must be either -9 or +8.

Since W represents width, a physical measurement, we eliminate the negative result and conclude that W = 8 units.  Then L = W + 1 = 9 units.

Note that (8)(9) = 72, as we already know.

The length of the rectangle is: [tex]\[ {9} \] units.[/tex]

Let's denote the width of the rectangle as \( w \) and the length of the rectangle as \( l \).

According to the problem, the length \( l \) is given by:
[tex]\[ l = w + 1 \][/tex]

The area of the rectangle is given by:
[tex]\[ \text{Area} = l \times w = 72 \][/tex]

Substituting the expression for \( l \) into the area formula:
[tex]\[ (w + 1) \times w = 72 \][/tex]

This can be rewritten as:
[tex]\[ w^2 + w - 72 = 0 \][/tex]

We now have a quadratic equation. To solve this, we can use the quadratic formula:
[tex]\[ w = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]\\where \( a = 1 \), \( b = 1 \), and \( c = -72 \).\\[/tex]
Plugging in these values:
[tex]\[ w = \frac{-1 \pm \sqrt{1^2 - 4 \cdot 1 \cdot (-72)}}{2 \cdot 1} \]\[ w = \frac{-1 \pm \sqrt{1 + 288}}{2} \]\[ w = \frac{-1 \pm \sqrt{289}}{2} \]\[ w = \frac{-1 \pm 17}{2} \][/tex]

This gives us two potential solutions for \( w \):
[tex]\[ w = \frac{16}{2} = 8 \]\[ w = \frac{-18}{2} = -9 \][/tex]

Since a width cannot be negative, we discard \( w = -9 \) and take \( w = 8 \).

Therefore, the width \( w \) is 8 units. Using the relationship \( l = w + 1 \), we find:
[tex]\[ l = 8 + 1 = 9 \][/tex]

So, the length of the rectangle is: [tex]\[ {9} \] units.[/tex]

Answer:

[tex]P(x)=-0.3x^2+56x-14[/tex]

[tex]P(x)=59x-0.3x^2-3x-14[/tex]

Combine like terms.

[tex]P(x)=-0.3x^2+(59x-3x)-14[/tex]

[tex]P(x)=-0.3x^2+56x-14[/tex]  

Therefore, the required function is [tex]P(x)=-0.3x^2+56x-14[/tex]   .

Answer:

166 2/13 deg

Step-by-step explanation:

The sum of the measures of the interior angles of a convex polygon of n sides is 180(n - 2).

A hexagon has 6 sides, so n = 6.

sum of measures of angles = 180(n - 2) = 180(6 - 2) = 180(4) = 720

4x + 5x + 6x + 7x + 8x + 9x = 720

39x = 720

x = 720/39

x = 240/13

The largest angle has measure 9x.

9x = 9 * 240/13 = 2160/13

2160/13 = 166 2/13

Answer: 166 2/13 deg

the size of largest angle is  [tex]166\frac{2}{13}[/tex] degree

Hexagon is a two-dimensional geometrical shape that is made of six sides, having the same or different dimensions of length. Some real-life examples of the hexagon shape are a hexagonal floor tile, pencil cross-section, clock, a honeycomb, etc. It can be either regular (with 6 equal side lengths and equal angles) or irregular (with 6 unequal side lengths and angles).

According to the question,

The sum of the measures of the interior angles of a convex polygon of n sides is 180(n - 2).

A hexagon has 6 sides, so n = 6.

sum of measures of angles = 180(n - 2)

                                             = 180(6 - 2)

                                             = 180 × 4

                                             = 720

4x + 5x + 6x + 7x + 8x + 9x = 720

39x = 720

x = 720/39

x = 240/13

The largest angle has measure 9x.

9x = 9 × 240/13 = 2160/13

[tex]\frac{2160}{13}[/tex]  = [tex]166\frac{2}{13}[/tex]

Hence, the size of largest angle is  [tex]166\frac{2}{13}[/tex] degree

Answer: [tex]32009355.90cm^3[/tex]

Step-by-step explanation:

Formula: [tex]V=Bh\\[/tex]

Since the base is a circumference, we can replace B for the area of a circumference formula.

[tex]V=\pi r^2h[/tex]

What we have here is 12 ft as the diameter of the circumference. A diameter is twice the radius, therefore we can conclude that if we take the diameter and divide it by 2, it will give us the radius.

[tex]12/2=6ft[/tex] this is the radius.

Now plug all this information into your formula.

[tex]V=(3.14)(6ft)^2(10ft)\\V=(3.14)(36ft^2)(10ft)\\V=1130.40ft^3[/tex]

Our values are in feet but the question requires cm. Let's convert from [tex]ft^3[/tex] to [tex]cm^3[/tex].

Normally, our conversion factors are raised to the power of 1, but in this case it's raised to the power of 3. So, first let's see how many cm are 1 ft.

[tex]1ft=30.48cm[/tex]

Here is where magic comes. We can raise both to the power of 3, in order to find the cubic ft and cm that we need as our conversion factors.

[tex](1ft)^3=(30.48cm)^3\\1ft^3=28316.8cm^3[/tex]

It will hold 200 Litres  of water

Step-by-step explanation:

To find the number of litres of water the fish tank can hold, we will follow the steps below;

Write down the formula for calculating its volume

V = l×w×h

where v = volume of the tank

w=width of the tank  

l = length of the tank

From the question given;

w= 50 cm = 0.5 m

height h = 20 cm = 0.2 m

l = 2 m

V= l×w×h

Final answer:

To calculate the principal with an interest of $119.88, an interest rate of 3.6%, and a time of 3 years, use the simple interest formula. By rearranging the formula and doing the math, the principal amount is found to be $1,110.

Explanation:

To find the principal amount when you know the interest earned, the interest rate, and the time, you can use the formula for simple interest which is Interest = Principal × rate × time. Our goal is to rearrange the formula to solve for the principal.

Given that the Interest earned is $119.88, the interest rate is 3.6% (or 0.036 when converted to a decimal), and the time is 3 years, we can plug these values into the formula:

Interest = Principal × rate × time
$119.88 = Principal × 0.036 × 3
$119.88 = Principal × 0.108

To find the Principal, divide the interest earned by the product of the rate and time:

Principal = $119.88 / 0.108
Principal = $1,110

The principal amount is $1,110.
