Answer:

The figure created with the points (-2, -3), (-2, 5), (1, -3) and (1, 5) is a rectangle.

Which shape is a rectangle?

A rectangle is oblong. It has two pairs of parallel sides and four right angles. A rectangle can also be known as an equiangular quadrilateral. This is because a rectangle is a quadrilateral shape (4-sided shape) that hasparallel sides, equal to one another, and all 4 corners have angles that are90º.

The fountain is made up of two semicircles and one quarter circle. Find the perimeter and area of the fountain.
antoniya [11.8K]

Answer:

628ft²

Step-by-step explanation:

From the diagram, we are given the following

diameter of the semicircles

2semi circles  = 1 circle

Area of 2semicircles = πd²/4

Area of 2semicircles = 3.14(20)²/4

Area of 2semicircles = 3.14*400/4

Area of 2semicircles = 3.14*100

Area of 2semicircles = 314ft²

Area of the quarter circle =  πd²/4 * 1/4

Area of the quarter circle =  πd²/16

d = 2r

d = 2*20

d = 40ft

Area of the quarter circle  = 3.14(40)²/16

Area of the quarter circle = 3.14*1600/16

Area of the quarter circle = 3.14*100

Area of the quarter circle = 314ft²

Area of the fountain = 314ft²+314ft²

Area of the fountain = 628ft²

Solve 0=4x^2+12x+9 using the quadratic formula.
MAXImum [283]
The quadratic formula is x =  \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}.  With the values from this equation plugged in, it looks like this:

x = \frac{-12 \pm \sqrt{12^2 - 4(4)(9)} }{2(4)} \\  \\ x = \frac{-12 \pm \sqrt{144 - 144} }{8}  \\  \\ x =  \frac{-12}{8}  \\  \\ x = - \frac{3}{2}

The solution is x = - 3/2
