Answer:

To convert from Cartesian Coordinates (x,y) to Polar Coordinates (r,θ):

1. r = √ ( x2 + y2 )

2. θ = tan-1 ( y / x )

I hope it's helpful!

Answer:

4x - 5y = 0

Step-by-step explanation:

First off all you do it like this

4x - 5y = 23

4x - 5y - 23 = 23 - 23

4x - 5y - 23 = 0

I WILL GIVE BRAINLIEST!! :D

STALIN [3.7K]

Answer:

The number in the middle is 60.

Step-by-step explanation:

The 2nd number = A

The 3rd number = B

The 4th number = C

Given:

(1) 130 + A + B = 300

(2) A + B + C = 200

(3) B + C + 10 = 100

Now, the work:

(2) can be modified to become A + B = 200 - C

Now, we can insert that into (1) and get the following;

130 + (200 - C) = 300

Open parentheses, simplify, you get C = 330 - 300.

C = 30

Using (3), we use above answer to get B + 30 + 10 = 100

Calculate, and get B = 100 - (30 + 10)

Simplify,

B = 60

There is your answer!

Cheers

WILL MAKE BRAINLIEST!! What will the coordinates of triangle are RST after it is translated four units right and three units up

pickupchik [31]

The coordinates of triangle RST after it is translated four units right and three units up are (0, 5), (7, 8) and (0, -1)

<h3>How to determine the coordinates?</h3>

From the figure, the coordinates of the triangle RST are:

R = (-4, 2)

S = (3, 5)

T = (-4, -4)

The rule of translation is given as:

Four units right
Three units up

This is represented as:

(x, y) = (x + 4, y + 3)

So, we have:

R' = (-4 + 4, 2 + 3) = (0, 5)

S' = (3 + 4, 5 + 3) = (7, 8)

T = (-4 + 4, -4 + 3) = (0, -1)

Hence, the coordinates of triangle RST after it is translated four units right and three units up are (0, 5), (7, 8) and (0, -1)
