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

Answer:
<u>Each cheeseburger cost $5.25</u>
Step-by-step explanation:
First, we must subtract the price of the taco, $2.75, from the total amount spent at dinner. This leaves us with 21 dollars.
Now, we must divide 21 by 4, this will show us the price of each cheese burger.
21 ÷ 4 = 5.25
So, each cheeseburger cost $5.25.
(a)
Total amount = SI + Amount
= 90 + 1800 = $1890
(b)
Total amount = SI + Amount
= 936 + 2600 = $ 3236
(c)
Total amount = SI + Amount
= 93.75 + 3125 = $ 3,218.75
Answer:
he volume of cube with side length of four and a half centimeters,
(4.5)³ = 91.125 cm³
Step-by-step explanation:
<u>Formula:</u>
Volume of a cube with side 'a' is given by,
Volume, V = a³
<u>To find the volume of cube</u>
It is given that,a cube has a side length of four and a half centimeters
⇒ a = 4.5
Volume V = a³
V = (4.5)³ = 91.125 cm³
Therefore the volume of cube with side length of four and a half centimeters= 91.125 cm³
