n ∈ natural even numbers

Step-by-step explanation:

1 + 3 + 5 + 7 + … + (2n-1)

sum of the first n terms :

Sₙ = n/2(a + Uₙ)

Sₙ = n/2(1 + 2n - 1)

Sₙ = n/2(2n)

Sₙ = n²

∴ so, the solution of n is all natural even numbers

Answer:

2 and 2

8 and 4

Step-by-step explanation:

Plug the respective x values in to find the y-values or use a GDC.

1. If the square of a number is added to 8 times the number, the result is 100.

Let x be the number.

Equation: x² + 8x - 100 = 0

2. Mr. Apoloan wants to lay out a rectangular playground which will contain 30 square feet. The desired length will be 7 times the width.

Area: 30ft²

Length: 7w

Width: w

Area of a rectangle: LW

(7w)w = 30ft²

Equation: 7w² - 30 = 0

Answer:

Where is the question ?

The distance from the road where an intruder would be in danger is 27.48 m.

To know how far from the road an intruder is in danger due to the dog, it is necessary to carry out the following procedure:

Establish the range of the dog with a circle of 15 meters in radius around the post on which he is tied.

In this part it can be inferred that a part of the path is in the range of the dog between points B and D (In this area the intruder would be in danger)

From this we know the following data:

To know the length of points BC and CD we must perform a calculation using the formula of the Pythagorean theorem.

Later we use the same procedure to find the length CD.

Finally, we add both lengths (BC + CD) to know the distance in which an intruder is in danger within the dog's range.

Answer:

-2,-2

Step-by-step explanation:

if you plug the numbers in you get:

(2*-2)+-2≤−4

so that's -4+-2≤−4

which equals -6≤−4

and as always, the bigger the negative number, the less value it has

Answer:

21 T-shirts, (this is just a thought of what i think i need to do) Hope it helps

Step-by-step explanation:

I think iv seen this question somewhere so did u forget to put 22?

Here is the explaination if u did...

5T -22 = 83

revenue minus expense = profit

5T = 83+22 = 105

T = 105/5 = 21 T shirts sold

Answer:

b = -ax + 4x + 2

Step-by-step explanation:

8x - 3x + 2 - x = ax + b

~Combine like terms

4x + 2 = ax + b

~Subtract ax to both sides

4x - ax + 2 = b

~Rewrite

b = -ax + 4x + 2

Answer:

C

Step-by-step explanation:

first of all since the line is solid then we know that the answer is not D or B.

so it has to be either A or C.

now to graph it let's start with A.

you would go up 5 on the y axis and since there isn't enough space go down 4 and to the left 1. the line doesn't match with the one in the picture so A is not the answer.

now let's try with C.

you would go down 5 on the y axis and then go up 4 and to the right 1. the line matches up so C is your answer.

-5 is the slope
