For each sequence, find the first 4 terms and the 10th term
1) 2n-1

Answers

Answer 1

Answer:

1st term: 1, 2nd term: 3, 3rd term: 5, 4th term: 7 & 10th term: 19

Step-by-step explanation:

1st term: 2(1) - 1

              2 - 1 = 1

2nd term: 2(2) - 1

                4 - 1 = 3

3rd term: 2(3) - 1

               6 - 1 = 5

4th term: 2(4) - 1

               8 - 1 = 7

10th term: 2(10) -1

                20 - 1 = 19

f/2 = 5/8 what is the value of f

Answers

Answer:

f = 5/4

Step-by-step explanation:

f/2 = 5/8

Multiply both sides by 2.

f = 10/8 = 5/4

Answer:

f=1.25

Step-by-step explanation:

f/2=5/8

To get 8, you must multiply 2 by 4.

So

You must do the same to the numerators -

4 times x = 5

5/4=1.25

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).

Plot triangles PQR and P′Q′R′ on your own coordinate grid.

Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)

Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)

Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)

Answers

Answer:

The scale factor from triangle PQR to P'Q'R' is 1/4.

The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.

If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).

No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

Answer:

22, I think

Step-by-step explanation:

You count all the squares on all of the faces.

So you count the two on the top and double it for the bottom, so four

Then, on the sides you have three so you double that and get six

Next, you double the six squares on the other side and get twelve.

Lastly, you add them up!

4 + 6 + 12

Answer:

Step-by-step explanation:

Square Area

8-3 to get the right side of the square which equals 5. So the square is 5*6=30

Triangle Area

To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5

but you have 2 triangles so multiply 4.5*2 and that's 9.

Conclusion

So, 30+9=39

Answer:

[tex]\Huge\boxed{x=29}[/tex]

Step-by-step explanation:

Hello There!

Once again the angles shown are supplementary angles meaning that the sum of the measure is equal to 180

so we use this equation to solve for x

180 = x + 4x + 35

step 1 combine like terms

x + 4x = 5x

now we have 180=5x+35

step 2 subtract 35 from each side

180 - 35 = 145

35 -35 cancels out

now we have 145 = 5x

step 3 divide each side by 5

5x/5=x

145/5=29

we're left with x = 29

Answer:

(×+35)+4×=180°[sum of angles in a str. line ]

5×=180-35

5×=145

5x/5=145/5

x=29
