Answer:

(A)3.44 square feet

Step-by-step explanation:

Length of The Square = 4 feet

Area of the Square poster board = 4 X 4=16 Square Feet

In each of the circles,

Diameter = 2 Feet

Radius = 2/2 = 1 Feet

Area of a circle =\pi r^2

Area of 1 circle =\pi*1^2=\pi ft^2

Area of the 4 circles =4*\pi=4\pi ft^2

Therefore:

Area of the leftover Poster= Area of the Square- Area of the 4 Circles

=16-4\pi\\=16-4*3.14\\=16-12.56\\=3.44 ft^2

Y=143.3(5)^2+1823.3(5)+6820
MA_775_DIABLO [31]

As the question is written, the <em>correct answer</em> is:


19519.


Explanation:


Our question states

y = 143.3(5)² + 1823.3(5) + 6820


To evaluate this, we use the order of operations (PEMDAS). There is nothing to be evaluated in parentheses, so P is taken care of.


The E part, exponents, is 5². This is 25, which gives us:

y = 143.3(25) + 1823.3(5) + 6820


Next we have M and D, multiplication and division (in the order they appear). Our multiplication is:

143.3(25) = 3582.5; and

1823.3(5) = 9116.5.


This gives us:

y = 3582.5 + 9116.5 + 6820


Lastly, we add these:

y = 12699 + 6820

y = 19519

Write an equation for the parabola whose vertex is at (4, 12) and which passes through (5, 21)
laiz [17]

Answer:

y - 12 = 9(x - 4)

Step-by-step explanation:

The vertex (h, k) is (4, 12) and the point (5, 21) is on the graph.  Assuming that this is a vertical parabola, opening up (because the coordinate 21 is greater than the coordinate 12), we insert the knowns into  y - k = a(x - h)^2, obtaining

21 - 12 = a(5 - 4), or  9 = a.  With a known, we can write the desired equation:

y - 12 = 9(x - 4)
