Convert the Cartesian equation x - 5 = 0 to a polar equation.

Mathematics
1 answer:
mylen [45]3 years ago
5 0

Answer:

  r = 5sec(θ)

Step-by-step explanation:

The usual conversion is ...

  y = r·sin(θ)

  x = r·cos(θ)

__

The second of these can be used here.

  r·cos(θ) -5 = 0

  r·cos(θ) = 5

  r = 5/cos(θ) = 5sec(θ)

A suitable polar equation is ...

  r = 5sec(θ)

PLEASE HELP IM STUCK

The number of outcomes possible from flipping each coin is 2, therefore;

  • The expression that can be used to find the number of outcomes for flipping 4 coins is: 2•2•2•2

<h3>How can the expression for the number of combinations be found?</h3>

The possible outcome of flipping 4 coins is given by the sum of the possible combinations of outcomes as follows;

The number of possible outcome from flipping the first coin = 2 (heads or tails)

The outcomes from flipping the second coin = 2

The outcome from flipping the third coin = 2

The outcome from flipping the fourth coin = 2

The combined outcome is therefore;

Outcome from flipping the 4 coins = 2 × 2 × 2 × 2

The correct option is therefore;

  • 2•2•2•2
