Answer:

A) (3,-8); Reflection

Step-by-step explanation:

The question kind of gave you a hint. Look at how the coordinate point is arranged...

(-y,-x)

That means all positive become negatives and all negatives become positives. This gives you the coordinate of (3,-8).

As for reflection or rotation, the image's coordinates FLIPPED, like how images do in a mirror's reflection.

This means the answer would be A) (3,-8); Reflection.

Which is a possible expression for the series

Anvisha [2.4K]

Without considering the sign:

It's sigma(1 to 5, 5k+2)

Since the first item is minus, you simply add (-1)^k

So it's sigma(1 to 5, (-1)^k * (5k+2)

I choose A

There is no possible answer.
The #s are 420, 480, and 540.
None of them are 40 away from a multiple of 100.
However, it is was between 300 and 600, the answer would be 360.

Find the distance between point (2, 7) and line y=1/3x-1/3.

oee [108]

2 = x. 7 = y

2 = 1/3 * 7 -1/3
1/3 * 7 to get 7/3
2 = 7/3 - 1/3 to get 6/3
Divide both sides by 2
2 = 2
Sorry if my math is wrong

The pattern in the given series of amount in the account are in the form of

arithmetic and geometric progression.

The function for Option 1 is; $\underline{ f(n) = 1,100 + (n - 1) \cdot 100}$

The function for Option 2 is; $\underline{f(n) = 1,100 \times 1.1^{(n - 1)}}$

Reasons:

The given table of values is presented as follows;

$\begin{tabular}{c|c|c|c|}Number of years&1&2&3\\Option 1 (Amount in dollars)&1,100&1,200&1,300\\Option 2 (Amount in dollars)&1,100&1,210&1,331\end{array}\right]$

In Option 1, the amount in dollars for each year has a common difference of d = 100

The first term, a = 1,100

Therefore;

The Option 1 can be represented as an arithmetic progression , A.P. in the

form, tₙ = a + (n - 1)·d as follows;

For the Option 1, we have;

The amount in dollars after <em>n</em> years, $\underline{ f(n) = 1,100 + (n - 1) \cdot 100}$

For Option 2, it is possible to find;

1,331 ÷ 1,210 = 1,210 ÷ 1,100 = 1.1

Therefore;

The terms in the Option 2 have a common ratio of r = 1.1

The Option 2 is a geometric progression, G.P.

The first term in Option 2 is a = 1,100

Which gives, the nth term, tₙ = a·r⁽ⁿ ⁻ ¹⁾

Therefor;

The function for the Option 2 is; $\underline{f(n) = 1,100 \times 1.1^{(n - 1)}}$
