Answer:

x^2+y^2=(x^2+y^2-2y)^2

Here we are given that

r=1+2sin

we know that the polar cordinates are represented as

x=rsin

y=rcos

Also squaring both and adding them gives you ,

Hence

also r=1+2sin

1+2sin =

Also ,

r = r=1+2sin

also sin =

Hence replacing sin we get

A city is building a fence around a rectangular playground if the perimeter of the playground is 104 feet and the length of one
34kurt

Answer:

20 ft

Step-by-step explanation:

We know that

Perimeter of rectangle = 2(l + w)

Let the width be w

=> 104 = 2(32 + w)

=> 104/2 = 32 + w

=> 52 = 32 + w

=> 52 - 32 = w

=> 20 = w

Hence z

Width of playground is 20 ft

Demitri's parents begin saving for his college fund when Demitri is 10 years old. They invest $5,000 in an account that earns 1.
qaws [65]

Answer:

yes

Step-by-step explanation:

A = P(1 + r)^t

A = total amount

P = principal

r = interest rate, as a decimal

t = time, in years

A = 5000·[(1 + .012)^8]

A = 5000(1.1001)

A = 5,500.65

amount of investment after 8 years = $5,500.65

two years of community college = $5,400
