Here is the question | | | | v

raketka [301]

Answer:

16.5 square feet

Step-by-step explanation:

The logo consists of

rectangle with sides of 3 ft and 1.5 ft;
trapezoid with bases 3 ft, 4 ft and height of 3 ft;
triangle with base of 1.5 ft and height of 2 ft.

The area of rectangle:

$A_{rectangle}=1.5\ ft\times 3\ ft=4.5\ ft^2$

The area of trapezoid:

$A_{trapezoid}=\dfrac{3\ ft+4\ ft}{2}\times 3 \ ft=3.5\ ft\times 3 \ ft=10.5 \ ft^2$

The area of triangle:

$A_{triangle}=\dfrac{1}{2}\times 1.5\ ft\times 2 \ ft=1.5\ ft^2$

Hence, the area of logo:

$A=A_{rectangle}+A_{trapezoid}+A_{triangle}=4.5\ ft^2+10.5\ ft^2+1.5\ ft^2=16.5\ ft^2$

Find the center and radius of the circle with equation (x + 3)^2 + (y – 6)^2 = 100.

Sonja [21]

Answer:

center (-3,6)

radius(r) 10

Step-by-step explanation:

The center-radius form (it is really called standard form) of a circle is:

$(x-h)^2+(y-k)^2=r^2$

where $(h,k)$ is the center and $r$ is the radius.

Compare the following:

$(x-h)^2+(y-k)^2=r^2$

$(x+3)^2+(y-6)^2=100$

You should see the following:

$-h=3$

$-k=-6$

$r^2=100$ .

$-h=3 \text{ implies }h=-3$ .

$-k=-6 \text{ implies } k=6$ .

$r^2=100 \text{ implies } r=\sqrt{100}=10$ .

So the center is (-3,6) and the radius is 10.
