Transform the polar equation to a Cartesian (rectangular) equation: r= 4sinθ

Mathematics

Answer:

  x^2 +y^2 = 4y

Step-by-step explanation:

Using the usual translation relations, we have ...

  r^2 = x^2+y^2

  x = r·cos(θ)

  y = r·sin(θ)

Substituting for sin(θ) the equation becomes ...

  r = 4sin(θ)

  r = 4(y/r)

  r^2 = 4y

Then, substituting for r^2 we get ...

  x^2 +y^2 = 4y . . . . . matches the first choice

In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-s
Bond [772]

Answer:

95.44%

Step-by-step explanation:

Mean (m) = 48

Standard deviation (sd) = 9

n = 12

Zscore = (x - m) /sd

X = 30

Zscore = (30 - 48) / 9

Zscore = - 2

X = 66

Zscore = (66 - 48) / 9

Zscore = 2

percentage of daily phone calls numbering between 30 and 66 = P(z < 2) - p(z < - 2)

P(z < 2) = 0.9772

P(z < - 2) = 0.0228

Hence,

0.9772 - 0.0228 = 0.9544

0.9544 * 100% = 95.44

Crazy boy [7]

Jason has $2 worth of dimes and quarters. He has 13 more dimes than quarters. The Number of dimes = 15 and Number of quarters = 2.

<h3>What is a linear equation?</h3>

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

The total money = $2 = 200 cents

Types of coins are dimes and quarters

Number of dimes are 13 more than quarters

let number of dimes be x and quarters be y

so our equation

10x + 25y = 200\\x = (y+13)\\10(y+13) +25y= 200\\10y + 130 +25y = 200\\\\35y + 130 = 200\\y = 70/35 = 2
