Answer:

4,066\ in^{2}

Step-by-step explanation:

we know that

The area of the bedspread that is red is equal to the area of rectangle minus the area of the circle

step 1

Find the area of rectangle

The area is equal to

A=72*60=4,320\ in^{2}

step 2

Find the area of the circle

A=\pi r^{2}

we have

r=18/2=9\ in ----> the radius is half the diameter

assume

\pi=3.14

substitute

A=(3.14)(9)^{2}

A=254.34\ in^{2}

step 3

Find the area of the bedspread that is red

Find the difference of the areas

4,320\ in^{2}-254.34\ in^{2}=4,066\ in^{2}

Find the x intercepts of the parabola with vertex (6,-5) and y- int (0,175)
prisoha [69]
Hmmm so.. .it could be either a horizontal or vertical parabola, let's assume or use a vertical parabola vertex equation then... namely, the squared variable being "x".

\bf \qquad \textit{parabola vertex form}\\\\
\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array} \qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
\begin{cases}
h=6\\
k=-5
\end{cases}\implies y=a(x-6)^2-5
\\\\\\
\textit{we also know }
\begin{cases}
x=0\\
y=175
\end{cases}\implies 175=a(0-6)^2-5\implies 180=a6^2
\\\\\\
\cfrac{180}{36}=a\implies 5=a\qquad thus\qquad \boxed{y=5(x-6)^2-5}

\bf \textit{at the x-intercepts, y = 0, thus }\qquad 0=5(x-6)^2-5
\\\\\\
5=5(x-6)^2\implies \cfrac{5}{5}=(x-6)^2\implies \pm\sqrt{1}=x-6
\\\\\\
\pm 1+6=x\implies x=
\begin{cases}
7\\
5
\end{cases}

All of the following proportions are equivalent except
shtirl [24]
All are equal except A/D = C/B

I replaced the values with numbers
a=5 b=10 c=50 d=100

10/5=100/50 so it’s not b/a = d/c
5/10=50/100 so it’s not a/b = c/d
5/50 = 10/100 so it’s not a/c = b/d
5/100 is NOT 50/10 so it’s NOT a/d = c/b
