Use I = PRT to solve. (time in years)
vivado [14]

Simple interest is $ 9

<em><u>Solution:</u></em>

Given that,

P = $ 400

R = 9 \% = \frac{9}{100} = 0.09

T = 0.25 years

<em><u>The formula for simple interest is:</u></em>

I = P \times R \times T

Where,

I is the simple interest earned

R is the rate of interest in decimal

T is the number of years

<em><u>Substituting the values we get,</u></em>

I = 400 \times 0.09 \times 0.25\\\\I = 36 \times 0.25\\\\I = 9

Thus simple interest is $ 9

Convert the polar equation to an equivalent rectangular equation:
Alchen [17]

Answer:

The correct answer will be option b

Step-by-step explanation:

We know that x = rcos( θ ), and y = rsin( θ ), so let's rewrite this polar equation.

r = 4( x / r ) + 2( y / r ),

r = 4x / r + 2y / r,

r = 4x + 2y / r,

r / 1 = 4x + 2y / r ( Cross - Multiply )

4x + 2y = r²

We also know that r² = x² + y², so let's substitute.

x² + y² = 4x + 2y,

x² - 4x - 2y + y² = 0,

Circle Equation : ( x - 2 )² + ( y - 1 )² = ( √5 )²,

Solution : ( x - 2 )² + ( y - 1 )² = 5
