What is the approximate area of the figure?
Valentin [98]

Answer:

Answer D (2206.5 ft^2) is closest to the calculated answer 2206.85 ft^2.

Step-by-step explanation:

We can break up this figure into a 30 ft by 50 ft rectangle and a circle of diameter 30 ft.

The area of the rectangular part is A1 = (30 ft)(50 ft) = 1500 ft^2.

The area of the circular part is A2 = π(15 ft)^2 = 706.9 ft^2

Thus, the total area is approx A1 + A2, or 2206.86 ft^2 (Answer D)

4x^{2}+16y^{2}-24x+64y+36=0<br> The center is:<br> The vertices are:<br> The foci are:
gulaghasi [49]

For the given equation,4x²−y²−24x−4y+28=0.The center is (h,k)=(3,−2), vertex (h+a,k)=(4,−2) and (h−a,k)=(2,−2), foci is (h+c,k)=(5.23,−2) and (h−c,k)=(0.77,−2)

<h3>What is the equation?</h3>

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, the equation of the hyperbola is,

4x²−y²−24x−4y+28=0

Comparing the equation with the standard equation we get,

Center (h,k)=(3,−2)

Vertex (h+a,k)=(4,−2) and (h−a,k)=(2,−2)

Foci (h+c,k)=(5.23,−2) and (h−c,k)=(0.77,−2)

Asymptotes y=2x−8 and y=−2x+4

Thus, for the given equation,4x²−y²−24x−4y+28=0.The center is (h,k)=(3,−2), vertex (h+a,k)=(4,−2) and (h−a,k)=(2,−2), foci is (h+c,k)=(5.23,−2) and (h−c,k)=(0.77,−2)

What equation results from completing the square and then factoring? x^2+22x=31 A.(x+22)^2=53 B.(x+22)^2=152 C.(x+11)^2=152 D.(x
Paladinen [302]

Answer:

\boxed{\mathrm{Option \ C}}

Step-by-step explanation:

=> x^2+22x = 31

=> (x)^2+2(x)(11) = 31

Since b = 11 , So (11)^2 needs to be added to both sides

Adding (11)^2  to both sides

=> (x)^2+2(x)(11)+(11)^2 = 31+(11)^2

Completing the square

=> (x+11)^2 = 31+121

=> (x+11)^2 = 152
