Molly wants her rectangular rooftop garden plot to have an area of 21 square feet. If she makes the width 5 feet, what must be t
Over [174]
Area = length x width
21 = length x 5
length = 21/5 = 4.2

The length is inversely proportional to the width because as the length increases the width reduces and vice-versa

Convert r =-72/12+6 sin theta to Cartesian form.
PolarNik [594]
For converting polar to cartesian form we know
r =  \sqrt{x^2 + y^2}
x = rcos \theta , y = rsin \theta

Given equation is

r =  \frac{-72}{12} + 6sin \theta

We can simplify it as
r = -6 + 6sin \theta

Now we can write it as
r^2 = -6r + 6rsin \theta

Now we can use
r^2 = x^ 2+ y^2 , rsin \theta = y , r =   \sqrt{x^2 + y^2}
So equation we can write it as
x^2 + y^2 = -6 \sqrt{x^2 + y^2} + 6y
x^2 + y^2 - 6y = -6 \sqrt{x^2 + y^2}
On squaring both sides
(x^2 + y^2 - 6y)^2 = (-6 \sqrt{x^2 + y^2})^2
x^4 + y^4 + 36y^2 +2x^2y^2 -12y^3 -12x^2y = 36(x^2 + y^2)
x^4 + y^4 +36y^2 + 2x^2y^2 -12y^3 -12x^2y = 36x^2 + 36y^2
x^4 + y^4 + 36y^2 +2x^2y^2 -12y^3-12x^2y - 36x^2 - 36y^2 = 0
x^4 + y^4 -12y^3 + 2x^2y^2 - 12x^2y - 36x^2 = 0

A rectangular prism with a volume of 3 cubic units is filled with cubes with side lengths of 1/4 units.How many unit cubes does
blsea [12.9K]

Answer:

192

Step-by-step explanation:

The volume of a prism is 3 cubic units. Dividing each cube into 1/4 size cubes means each small cube will have 1/64 cubic inches.

This means 64 1/4 cubes fit into 1 cube. So for 3 cubes, 3*64 = 192 cubes.

How do you solve the equation x over 4 +2 = -12
Makovka662 [10]

For this case we must solve the following equation:

\frac {x} {4} + 2 = -12

Subtracting 2 from both sides of the equation we have:

\frac {x} {4} = - 12-2

Equal signs are added and the same sign is placed.

\frac {x} {4} = - 14

Multiplying by 4 on both sides of the equation we have:

x = -14 * 4\\x = -56

Thus, the solution of the equation is x = -56

Answer:

x = -56
