The rectangular representation of the polar point of (4 , 300) is (2,- 2√3)
According to the statement
we have given a coordinates of the rectangle and we have to find the polar coordinates.
So, For this purpose, we know that the
We Use the conversion formulas to convert from polar coordinates to rectangular coordinates which are
x = rcosθ
y = rsinθ
Substitute the given values in it then
x=(4)cos(300)
y=(4)sin(300)
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
x=(4)cos(60) -(1)
y= - (4)sin(60) -(2)
And then
x=(4)cos(60)
x=(4)(1/2)
x = 2 -(3)
and
y= - (4)sin(60)
y= - (4)(√3/2)
y= - 2√3 -(4)
Replace (3) with (1) and (4) with (2)
then it becomes
x = 2 and y= - 2√3
The rectangular representation of the polar point of (4 , 300) is (2,- 2√3)

Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5
Step-by-step explanation:
Given: Breanna saves 75% of her earnings to buy new school clothes.
Earnings for Breanna = $ 750
The amount of money she saves to buy clothes = 75% of 750
= 0.75 x 750 [75%= 0.75]
= $ 562.5
Hence, the best estimate for the amount of money she saves to buy clothes = $ 562.5
Answer:
It takes 85 seconds to go 12.75 miles
Step-by-step explanation:
We are given
An airplane is flying from New York City to Los Angeles
the distance it travels in Miles D is related to the time in seconds T by the equation
we are given to find time when distance is 12.75 miles
so, we can set d=12.75
and then we can solve for T
We can divide both sides by 0.15
So,
It takes 85 seconds to go 12.75 miles
