A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the objects. The polar coordinate of the coordinate (1, -3) is (√10, 288.435).

<h3>What are coordinates?</h3>

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

The polar coordinate of the coordinate (1, -3) are,

r = √(x² + y²) = √[(1)²+(-3)²] = √10

θ = tan⁻¹(-3/1) = -71.565 = 288.435

Hence, The polar coordinate of the coordinate (1, -3) is (√10, 288.435).

Step-by-step explanation and answer:

For this you just need to plug in x for y = f(1/5x)

1/5(-4) = -4/5 or -0.8

1/5(-1) = -1/5 or -0.2

1/5(0) = 0

1/5(3) = 3/5 or 0.6

1/5(6) = 6/5 or 1.2 or 1 1/5

Tulsa has 4 times as many mangoes as Julie. Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie . How many
vova2212 [387]

Answer:

24

Step-by-step explanation:

Let the number of mangoes owned by Tulsa be T and that by Julie be J

If Tulsa has 4 times as many mangoes as Julie then

T = 4J

Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie

T + 6 = 5J

Solve both equations simultaneously by substitution

4J + 6 = 5J

Collect like terms

6 = 5J- 4J

J = 6

Since

T = 4J

T = 4 * 6

= 24

Hence Tulsa had 24 mangoes at first
