In the diagram shown, segments AE and CF are both perpendicular to DB.
DE=FB, AE=CF. Prove that ABCD is a parallelogram.

The recursive sequence are: 17, 13, 9, 5, 1.

The recursive rule for the sequence  [tex]a_{n}[/tex] = 17 - 4n is

[tex]a_{1[/tex] = 17

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 4 for n ≥ 2

[tex]a_{1[/tex] = 17

[tex]a_{2}[/tex] = [tex]a_{1[/tex]  - 4 = 17 - 4 = 13

[tex]a_{3}[/tex] = [tex]a_{2}[/tex] - 4 = 13 - 4 = 9

[tex]a_{4}[/tex] = [tex]a_{3}[/tex] - 4 = 9 - 4 = 5

[tex]a_{5}[/tex] = [tex]a_{4}[/tex]  - 4 = 5 - 4 = 1

and so on.

Therefore, the recursive sequence are: 17, 13, 9, 5, 1.

Answer: Let's start by subtracting the cost of the glider airplane from the total amount of money you started with:

$20 - $3 = $17

We know that you spent $15 of that $17 on the bouncy ball, since you had $15 left over after buying both items:

$17 - $15 = $2

Therefore, you spent $2 on the bouncy ball.

Answer: $2.

Step-by-step explanation:

The area and cost of each of the lots is given below

The area and cost of each of the lots is calculated below

To calculate the rectangle trapezoid, it will be:

B = 140m

h = 50m

b = 70m

Note that Area of Lot 1 : A =(B+b)h/2

Hence Height will be:

A= (140m+ 70m) 50m/2

A = 5250 m²

Cost: C = 5250m² *800 pesos = $4,200,000

Lot 2 is another rectangle trapezoid:

B = 150m

b = 80m

h = 50m

Area: A= (150m+ 80m)50m/2

A = 5750 m²

Cost: C = 5750m²  x 800 pesos = $4,600,000

So, for Lot 3 which is a rectangle:

b = 70m

to = 50m

Area: A =a x b

W=50m x 70m

A  = 3500 m²

Cost: C = 3500m² x 800 pesos = $2,800,000

Lot 4 is a right triangle:

b = 70m

h = 50m

Area: A =b x h/2

A= (50m x 70m)/2

A = 1750 m²

Cost: C = 1750 m² x 800 pesos = $1,400,000

So for Lot 5 that is a rhomboid:

b = 150 base meters

h=50m

Area: A=b x h

A= (150m  x  50m

H = 7500 m²

Cost: C = 7500m² x  800 pesos = $6,000,000

So, for Lot 6 that is an isosceles triangle:

b = 140m

h= 50m

Area: A =b x h/2

A= (140m x  50m)/2

A = 3500 m²

Lastly, the Cost: C = 3500m²  x 800 pesos = $2,800,000

According to the information, the customer would save $492 in the first year by switching to Intellivision; the customer would save $207 in the second year by using Intellivision; ElectroniSource would be cheaper in the third year.

a. To calculate the annual cost for ElectroniSource: $42/month for phone service x 12 months = $504/year, $35/month for internet service x 12 months = $420/year, and $59/month for cable television x 12 months = $708/year.

So the total annual cost with ElectroniSource would be $504 + $420 + $708 = $1,632.

With Intellivision, the flat monthly fee for all three services is $95, so the total annual cost would be $95 x 12 months = $1,140.

Therefore, the customer would save $1,632 - $1,140 = $492 in the first year by switching to Intellivision.

b. After the first year, Intellivision raises the rates by 25%, so the new monthly fee would be $95 x 1.25 = $118.75.

The total annual cost in the second year would be $118.75 x 12 months = $1,425.

Using the same services, the annual cost with ElectroniSource would still be $1,632.

Therefore, the customer would save $1,632 - $1,425 = $207 in the second year by using Intellivision.

c. If Intellivision raises the rates by 16% in the third year compared to the second year, the new monthly fee would be $118.75 x 1.16 = $137.95.

The total annual cost in the third year would be $137.95 x 12 months = $1,655.4.

The annual cost with ElectroniSource would still be $1,632.

Therefore, ElectroniSource would be cheaper in the third year.

According to given data GR(x) * GR(y) = 3 * 2m - 5

The given monomial is P(x;y) = -mx^3m-1 * y^2m-7, and it is known that GA(P) = 17.

We need to find the values of GR(x) and GR(y), which are the degrees of the monomial with respect to x and y, respectively.

Using the formula GA(P) = GR(x) + GR(y), we get GR(x) + GR(y) = 17.

Now, we can write the monomial as P(x;y) = (-m) * x^(3m-1) * y^(2m-7).

Therefore, GR(x) = 3m-1 and GR(y) = 2m-7.

Multiplying these two values, we get GR(x) * GR(y) = (3m-1) * (2m-7) = 6m^2 - 23m + 7.

Hence, the final answer is GR(x) * GR(y) = 6m^2 - 23m + 7.

Then we can use the given distances to find the length of each side of the triangle ABC, and the angles to find the angle opposite each side.

Using the angle opposite side AB as a reference angle, we can find the other angles as follows:

Angle BAC = 180° - (71° + 63°) = 46°

Angle ABC = 180° - (46° + 90°) = 44°

Now we can use the Law of Cosines:

[tex]AC^2 = AB^2 + BC^2 - 2ABBCcos(44°)[/tex]

[tex]AC^2 = (141)^2 + (213)^2 - 2(141)(213)*cos(44°)[/tex]

Answer:

Yes, they are totally correct, I've checked with a calculator

According to the distance, it will take the jet 1 hour to overtake the small plane.

Let's first calculate the distance traveled by the small plane in the time it takes for the jet to overtake it. Since the small plane is flying for an extra 30 minutes, its travel time is "t + 0.5" hours. Therefore, the distance traveled by the small plane is:

Distance of small plane = Speed of small plane x Time of small plane

Distance of small plane = 240 x (t + 0.5)

Now, let's calculate the distance traveled by the jet in "t" hours:

Distance of jet = Speed of jet x Time of jet

Distance of jet = 360 x t

Since both planes are at the same point at the time of overtaking, we can set the distances traveled by both planes equal to each other:

240 x (t + 0.5) = 360 x t

We can solve for "t" using algebra:

240t + 120 = 360t

To determine the best estimation for centering the dresser along the wall, we need to consider the length of the wall and the length of the dresser. Let's call the length of the wall "W" and the length of the dresser "D".

Since we don't know the actual values of W and D, we'll have to work with the given options.

Option A suggests placing the dresser about 6 feet from each end of the wall. This would leave a space of W - 12 feet in the middle of the wall, which would be the total space available for the dresser to be centered.

Option B suggests placing the dresser about 8 feet from each end of the wall. This would leave a space of W - 16 feet in the middle of the wall, which would be the total space available for the dresser to be centered.

Option C suggests placing the dresser about 10 feet from each end of the wall. This would leave a space of W - 20 feet in the middle of the wall, which would be the total space available for the dresser to be centered.

Option D suggests placing the dresser about 12 feet from each end of the wall. This would leave a space of W - 24 feet in the middle of the wall, which would be the total space available for the dresser to be centered.

To find the best estimation for centering the dresser along the wall, we need to determine which option provides the closest match between the available space in the middle of the wall and the length of the dresser.

Without knowing the actual values of W and D, it's difficult to say for certain which option is best. However, we can make an educated guess by considering the lengths of typical bedroom walls and dressers.

Based on this, option C (placing the dresser about 10 feet from each end of the wall) seems like a reasonable estimation for centering the dresser along the wall. This option provides a space of W - 20 feet in the middle of the wall, which is likely sufficient for most dressers.

Of course, the actual placement of the dresser will depend on other factors as well, such as the layout of the room and the location of other furniture. It's always a good idea to measure carefully and test different arrangements before settling on a final placement for any piece of furniture.

Let x be the number of pencils Reema bought in August. According to the problem, she gave away 1/4 of the pencils, which means she kept 3/4 of the pencils. Then, she used 2/3 of what she had left, which means she used:

(2/3)(3/4)x = (1/2)x

So, if she used half of what she had left, she must have started with twice as many pencils. Therefore:

2x = total number of pencils she started with

And we know that she ended up with 3 pencils left, so:

2x - (1/4)(2x) - (1/2)x = 3

Simplifying this equation, we get:

Answer: The mean weight of the 11-person team is 207.3 pounds

Step-by-step explanation:

According to the question,

The mean weight of 4 backfield members = 234 lb
Therefore, the total weight of 4 backfield members = 4 × 234 = 936 lb

Similarly,
The mean weight of the 7 players = 192 lb
And the total weight of 7 players = 7 × 192 = 1344 lb

∴ Total weight of 11 players = (936 + 1344) lb = 2280 lb

We know that,

Mean =  [tex]\frac{Total Sum}{Total number of variables}[/tex]    

∴ To find the mean weight of the 11 players we need to divide the total weight by 11 :

Mean = [tex]\frac{2280}{11} = 207.27[/tex]

Rounding off to the nearest tenth we get,
Mean = 207.3

Hence, the mean weight of the team is approximately 207.3 pounds
