Alik [6]

Answer:

  (b)  (x, y) ⇒ (-x, y); (x, y) ⇒ (x + 1, y + 1)

Step-by-step explanation:

A graph shows the image is consistent with reflection over the y-axis

  (x, y) ⇒ (-x, y)

and translation right 1, up 1

  (x, y) ⇒ (x +1, y +1)

These transformations are listed in the second choice.

__

In the attachment, the original image is blue, the reflected image is purple, and the final translated image is red.

An arithmetic sequence has t1=5 and t2=8 find tn and sn
RoseWind [281]

Answer:

a_n=2+3n

\displaystyle S_n=\frac{7n+3n^2}{2}

Step-by-step explanation:

<u>Arithmetic Sequences </u>

The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

a_n=a_1+(n-1)r

Where

an = nth term

a1 = first term

r   = common difference

n  = number of the term

The sum of the n terms of an arithmetic sequence is given by:

\displaystyle S_n=\frac{a_1+a_n}{2}\cdot n

We are given the first two terms of the sequence:

a1=5, a2=8. The common difference is:

r = 8 - 5 = 3

Thus the general term of the sequence is:

a_n=5+(n-1)3=5+3n-3=2+3n

\boxed{a_n=2+3n}

The formula for the sum is:

\displaystyle S_n=\frac{5+2+3n}{2}\cdot n

\displaystyle S_n=\frac{7+3n}{2}\cdot n

Operating:

\boxed{\displaystyle S_n=\frac{7n+3n^2}{2}}

Tara is shown a picture of a dart board along with some dimensions. She knows that each triangular section in the dartboard is c
Romashka [77]

Answer:

The approximated length of arc x is 4 inches ⇒ C

Step-by-step explanation:

  • The diameter of the outer circle is 28 inches
  • There is a boundary with width 2 inches

That means the diameter of the inner circle is less than the diameter of the outer circle by 4 inches (2 in from each side)

  • The diameter of the inner circle = 28 - 4 = 24 inches

The circumference of the inner circles formed from 20 congruent arcs of length x inches

  • The circumference of the inner circle = 20 x

Now let us find x

The formula of the circumference of a circle is C = π d, where d is the diameter of the circle

∵ The diameter of the inner circle is 24 inches

∴ d = 24

∴ C = 24 π

∵ C = 20 x

- Equate 20 x by 24 π

∴ 20 x = 24 π

- Divide both sides by 20

∴ x = 3.769911184

- Round it to the nearest unit

∴ x ≅ 4

The approximated length of arc x is 4 inches
