Answer:

a reflection of ΔRST across the line y = –x

Step-by-step explanation:

A reflection across the line y = –x transforms point (x, y) into (-y, -x)

After reflecting ΔRST across the line y = –x we get:

R (-1, 3) -> (-3, 1)

S (3,-2) -> (2, -3)

T (1, -4) -> (4, -1)

where S is at the desired vertex

Answer:

2

Step-by-step explanation:

(x + 6) - (3x - 6)               Remove the brackets.

x + 6 - 3x + 6                 Collect like terms

Difference in points = 12 - 2x

If x = 5 then

Difference in points = 12 - 2*5

Difference in points = 12 - 10

Difference in points = 2

A vector has initial point at (3,-5) and terminal point at (-2,3). what are the characteristics of this vector?
Aleksandr [31]

Answer:

D

Step-by-step explanation:

If you plot both points on a graph you can see the angle is much larger than 58 degrees so it must be 122 degrees. The square root of 13 is less than 4, and you can see that the two points are further than four units apart. Sorry for a non-mathematical explanation, this is just how I solve these things lol.

Using an arithmetic sequence, it is found that:

i) They collected 300 bottles on June 25th.

ii) The day was July 18th.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

a_n = a_1 + (n - 1)d

In which a_1 is the first term.

In this problem, the sequence is: {417 ,404 ,391, .........}, hence the first term is a_1 = 417, the common difference is d = -13, and the equation is:

a_n = 417 - 13(n - 1)

Item i)

They started on June 15th, hence June 25th is the 10th day, thus:

a_{10} = 417 - 13(9) = 300

They collected 300 bottles on June 25th.

Item ii)

This is n days after June 15th, for which a_n = 1, hence:

a_n = 417 - 13(n - 1)

1 = 430 - 13n

13n = 429

n = 33

33 days after June 15th is July 18th.
