Answer:

Step-by-step explanation:

From the given coordinates

A(6, 0), B(0, 0) then AB = 6 - 0 = 6

B(0, 0), C(0, 8) then BC = 8 - 0 = 8

To calculate AC use Pythagoras' theorem on the right triangle formed

AC² = AB² + BC² = 6² + 8² = 36 + 64 = 100

Take the square root of both sides, hence

AC = [tex]\sqrt{100}[/tex] = 10

Perimeter = AB + BC + AC = 6 + 8 + 10 = 24 → C

To find the diameter of Monica's shirt button with a radius of 1 centimeter, we multiply the radius by 2, resulting in a diameter of 2 centimeters.

Explanation:

The question asks to determine the diameter of a button given its radius. The radius of Monica's shirt button is 1 centimeter. In geometry, the diameter of a circle is defined as twice the radius. Therefore, to find the button's diameter, you simply multiply the radius by 2.

Formula: Diameter = 2 × Radius

Calculation: Diameter = 2 × 1 cm = 2 cm.

Thus, the diameter of Monica's shirt button is 2 centimeters

-4/3 is the nth term

Answer:

The sum of terms 12  the geometric sequence 1,3,9...   = 265720

Step-by-step explanation:

Formula:-

Sₙ = a₁(1 - rⁿ)/(1 - r)

Where Sₙ - sum of n terms in the GP

a - First term of GP

r - Common ratio

n - Number

It is given the  geometric sequence 1,3,9....

To find the sum of 12 terms

Here a = 1, r = 3 and n = 12

Sₙ = a₁(1 - rⁿ)/(1 - r) = 1(1 - 3¹²)/(1- 3) = 265720

Answer:

The sum of the 12 terms = 265720

Step-by-step explanation:

* Lets study the geometric sequence rule

- If a1 = a , a2 = ar ,  a3 = ar² , a4 = ar³ , .........................

∴ an = a[(r)^(n-1)]

- Where a is the first term and r is the common ratio and

  n is the position of the term in the sequence

- The rule of the sum of some terms is Sn = [a(1 - r^n)]/(1 - r)

- Where n is the number of terms we want to add

* Lets check our terms in the sequence

- The terms are 1 , 3 , 9 , ..........

- To find the common ratio divide the 2nd term by 1st term

∵ the second term is 3 and the first term is 1

∴ 3/1 = 3

∴ The common ratio is 3

∵ n = 12 and a = 1

* Lets substitute the values of a , r , n in the rule of the sum to

  find the sum of the 12 terms

∴ S12 = [1(1 - 3^12)]/(1 - 3) = (1 - 3^12)/-2 = 265720

* The sum of the 12 terms = 265720

Replace x in each equation with 4:

f(x) = x^2 +2x-3 = 4^2 + 2(4) -3 = 16 + 8 -3 = 21

g(x) = x^2-9 = 4^2 -9 = 16-9 =7

Now you have values for f(x) and g(x) now you can solve for f/g and f+g:

f/g = 21 / 7 = 3

f+g = 21 + 7 = 28

For this case, we have that by definition:

[tex](f + g) (x) = f (x) + g (x)\\(\frac {f} {g})(x) = \frac {f (x)} {g (x)}[/tex]

We have the following functions:

[tex]f (x) = x ^ 2 + 2x-3\\g (x) = x ^ 2-9[/tex]

So:

[tex](f + g) (x) = x ^ 2 + 2x-3 (x ^ 2-9)\\(f + g) (x) = x ^ 2 + 2x-3 x ^ 2-9\\(f + g) (x) = 2x ^ 2 + 2x-12\\(f + g) (4) = 2 (4) ^ 2 + 2 (4) -12\\(f + g) (4) = 2 * 16 + 8-12\\(f + g) = 32 + 8-12\\(f + g) (4) = 28[/tex]

On the other hand:

[tex](\frac {f (x)} {g (x)}) = \frac {x ^ 2 + 2x-3} {x ^ 2-9}\\Evaluated\ at\ x = 4[/tex]

[tex](\frac {f (x)} {g (x)}) = \frac {4 ^ 2 + 2 (4) -3} {4 ^ 2-9} = \frac {16 + 8-3} {16 -9} = \frac {21} {7} = 3[/tex]

Answer:

[tex](f + g) (4) = 28\\(\frac {f} {g}(4)) = 3[/tex]

The distance between rest stops on the new map is approximately 4.262 miles.

To find the distance between the rest stops on the new map, we need to determine the distance between each rest stop on the original map and then convert it to the new scale. The original map has a scale of 2 inches = 39 miles, so the distance between each rest stop on the original map is (9 inches / 7 rest stops) * 39 miles. Simplifying this gives us 5.571 miles. To convert this distance to the new scale, we use the scale of 1 inch = 30 miles. So, the distance between each rest stop on the new map is (5.571 miles / 39 miles) * 30 miles, which equals approximately 4.262 miles.

The rest stops on the new map are approximately 19.2857 miles apart.

To find the distance between the rest stops on the new map, we need to determine the distance between the rest stops on the original map and then convert it to the new scale.

In the original map, the length of the highway is 9 inches and there are 7 rest stops.

Therefore, the distance between each rest stop on the original map is 9 inches / 7 rest stops = 1.2857 inches.

To convert this distance to the new scale, we multiply it by the ratio of the scales: 1.2857 inches * (1 inch / 2 inches) * (30 miles / 1 inch) = 19.2857 miles.

So, the rest stops on the new map are approximately 19.2857 miles apart.

My life is not linear. Time is not constant. My life (and time included) is just a series of times that do not run parallel to each other. Instead, they drift further or closer as a function of velocity and curvature of space time.

Answer: If you are looking for a linear equation in your life, an example could be the rate of the grass growing in your lawn. The y axis could be the height and the x axis could be the time. As it grows, the line representing the grass could go up gradually; when you cut it, the line can stop. Keep doing that for however long you'd like to represent the grass growing/getting cut.

The answer is: There is no solution, it's not possible for Shawn to catch up with Jason since both are riding at the same constant speed, there is always be a distance of 1 mile between.

If it's possible to Shawn to catch up with Jason, the following equation will be true:

Let be the station our origin, so:

[tex]ShawnPosition=JasonPosition\\20mph.x-2miles=20mph.x-1mile\\-2=-1[/tex]

So, since the equation is not fulfilled, there is not solution, meaning that it's not possible to Shawn to catch up with Jason since both started riding from different points keeping the same constant speed, there will always be a distance of 1 mile between them if they keep the speed constant.

Also, Shawn could have caught up with Jason if he were started with a speed of 21mph instead the Jason speeds (20mph), let's prove that:

[tex]ShawnPosition=JasonPosition\\21mph.x-2miles=20mph.x-1mile\\\\21mph.x-20mph.x=2miles-1mile\\\\mph.x=1mile\\x=1h[/tex]

So, by substituting "x" into the equations, we have:

[tex]ShawnPosition=JasonPosition\\21mph.1h-2mile=20mph.1h-1mile\\21miles-2miles=20miles-1mile\\19miles=19miles[/tex]

So, Shawn could have caught up with Jason if he were started with a 21 mph speed  instead starting with the Jason speed (20 mph).

Answer:

$3116

Step-by-step explanation:

First off, we need to find the value of the appliance after the down payment.

$2450 - $600 = $1850

This then makes our principal $1850.

P = $1850

r = 9% or 0.09

t = 4 years

To find the total cost of the appliance plus interest, we need to look for our accrued amount first.

A = P + Prt

A = $1850 + $1850(0.09)(4)

A = $1850 + $666

A = $2516

Now that we know our accrued amount, we then add our down payment to find the total cost.

Total cost = $2516 + $600

Total cost = $3116

To calculate the cost of an appliance with added interest, subtract the down payment from the purchase price to determine the amount of the loan. This is followed by the calculation of the total interest over the length of the loan. Adding these two amounts provides the total cost of the appliance plus interest, which in this case is $2516.

The total cost of the appliance plus interest can be calculated by first determining the amount of the loan made, which is the cost of the appliance minus the down payment. This comes out to $2450 - $600 = $1850.

Then, the add-on interest over 4 years is calculated by multiplying the amount of the loan by the annual interest rate and by the number of years. For this question, that is $1850 * 0.09 * 4 = $666.

So, the total cost of the appliance with interest added is the sum of the amount of the loan and the amount of the interest. Therefore, $1850 + $666 = $2516 is the total cost for the appliance plus interest.

Answer:

The Field's length is 93ft

Step-by-step explanation:

P=2L+2w

360=2(w+6)+2w

360=2w+12+2w

360=4w+12

348=4w

348/4=w

87=w

L=w+6

L=87+6

L=93

The width of a rectangular field surrounded by 360 feet of fencing is 87 feet. The length of the field, which is 6 feet more than the width, is 93 feet.

We are dealing with a rectangular field here, and we know that the length of a rectangle is equal to the total fencing (perimeter), divided by two, minus the width. Now, the problem states that the length is 6 feet more than the width. Therefore, we can create the following equation: 2x + 2(x + 6) = 360, where x is the width.

After simplifying this equation, we find that 4x + 12 = 360. Subtract 12 from both sides to get 4x = 348, and then divide by 4 to find that x = 87 feet. Thus, the width of the field is 87 feet. Since the length is 6 feet more than the width, we add 6 to 87 to get a length of 93 feet.

Answer:

Minimum area is : 1 * 35 = 35

Maximum area is : 19 * 17 = 323

Step-by-step explanation:

The parameter (P) of rectangle is calculated using:

P = 2(a+b)

We are given that,

P = 72

=> 2(a+b) = 72

=> a+b = 36

In rectangle, the lengths of both sides are different and a whole number (as mentioned in question), Therefore, the length of smaller side a can be varied from 1 to 17. Similarly, the length of larger side varies from 19 to 35.

The area can be easily calculated using a*b.

Minimum area is : 1 * 35 = 35

Maximum area is : 19 * 17 = 323

Answer:

Step-by-step explanation:

Look at the picture.

We have the rectangle 2πr × h and two circles.

Therefore the formula of a Surface Area is:

[tex]S.A.=2\pi rh+2\pi r^2[/tex]

We have r = 5m and h = 9m. Substitute:

[tex]S.A.=2\pi(5)(9)+2\pi(5^2)=90\pi+50\pi=140\pi\ m^2[/tex]

[tex]\pi\approx3.14\to S.A.\approx(140)(3.14)\approx440\ m^2[/tex]

Final answer:

To calculate the surface area of the cylinder, use the formula 2π(radius)(height) + 2π(radius)², with radius = 5m and height = 9m. The answer is approximately 440 square meters when rounded to the nearest square meter.

Explanation:

To find the approximate surface area of the cylinder, we can use the formula: Surface area = 2π(radius)(height) + 2π(radius)². Given a radius of 5 meters and a height of 9 meters, we can plug these values into our formula.

The area of the two circular bases is 2π(radius)² = 2π(5)² = 2π(25) = 50π square meters.

The area of the side (the rectangular part when the cylinder is unrolled) is 2π(radius)(height) = 2π(5)(9) = 90π square meters.

Adding both of these areas together gives us the total surface area:
50π + 90π = 140π square meters.

Using 3.14159 as an approximation for π, we get 140π = 140(3.14159) ≈ 439.8226 square meters, which can be rounded to the nearest square meter as 440 square meters.
