Answer:

  an = 5 +3(n -1)

Step-by-step explanation:

The n-th term of an arithmetic sequence is ...

  an = a1 +d(n -1)

Here, you have first term a1=5 and common difference d=8-5=3, so the n-th term is ...

  an = 5 +3(n -1)

_____

If you like, you can simplify this to ...

  an = 5 +3n -3

  an = 3n +2

Answer:

it's 3n-3

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = [tex]\frac{18}{25}[/tex]

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)

Answer:

102

Step-by-step explanation:

Write the formula. A = [tex]\frac{1}{2}[/tex] x B x H

Cut the figure

6 + 6 + 5=16

16 + 10=26

26 x 6=156

156 ÷ 2=78

6 x 4=24

78 + 24=102

Answer:

Total surface area of a cuboid is 376 square centimeter.

Step-by-step explanation:

Given : A cuboid of length 10 cm breadth 8 cm and height 6 cm.

To find : The total surface area of a cuboid?

Solution :

The total surface area of a cuboid is  

Where, l is the length l=10 cm

b is the breadth b=8 cm

h is the height h=6 cm

Substitute the value in the formula,

Therefore, Total surface area of a cuboid is 376 square centimeter.

Answer:

1/2, or 50% probability if you have equal amounts of even and odd numbers

do you have a list of the numbers or is it just in general ?

Answer:

It's most likely always be 50/50. You'll either get an odd number or an even one. Hope this helps!! (:

Answer:

Step-by-step explanation:

To solve this you could complete the square, use the quadratic formula, or factor it. This equation is easily factorable.

x^2-6x+8=0

(x-2)(x-4)=0

So x=(2,4)

Answer:

43, 44 and 45

Step-by-step explanation:

As it is mentioned consecutive, we can take the numbers as

x, x + 1 and x + 2

so x + (x + 1) + (x + 2) = 132

3x + 3 = 132

3x = 129

x = 43

Other two number are:

x + 1 = 44

x + 2 = 45

The numbers are 43, 44 and 45.

Answer:25/8 or if mixed number 3 1/25

Step-by-step explanation:

Answer and Step-by-step explanation:

2(5x - 5) = 6x + 50

Distribute the 2 to the 5x and -5.

10x - 10 = 6x + 50

Add 10 to both sides, and subtract 6x from both sides.

4x = 60

Divide both sides by 4.

x = 15

5y + 5 = 7y - 9

Subtract 5 from both sides, and 7y from both sides.

-2y = -14

Divide both sides by -2.

y = 7

Answer:

x=-5/11, y=-9/11. (-5/11, -9/11).

Step-by-step explanation:

3x+2y=-3

y=4x+1

---------------

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

3x+8x+2=-3

11x=-3-2

11x=-5

x=-5/11

y=4(-5/11)+1

y=-20/11+11/11

y=-9/11

Answer:

5

Step-by-step explanation:

3(2x-4)-8=5+x

6x-12-8=5+x

6x-x-20=5

5x-20=5

5x=5+20

5x=25

x=25/5

x=5

Answer:2861

Step-by-step explanation:

Answer:

y = (1/3)x + 2

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b, where y and x are variables, m is the slope of the line, that is the ratio of the change in vertical distance to horizontal distance while b is the y intercept of the graph.

From the graph, we can see that the y intercept (where the graph touches the y axis) is 2. Hence b = 2

Also, the slope (m) = change in y / change in x = 1 / 3

The equation of the line is:

y = (1/3)x + 2

Answer:y = (1/3)x + 2

Step-by-step explanation:

hope this helps

Answer:

3x+4y+7y = 3x + 11 y

Step-by-step explanation:

We need to simplify the given expression i.e.

3x+4y+7y

We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y

So,

3x+4y+7y = 3x + 11 y

Hence, the final simplification should be 3x + 11 y.
