Write the standard equation of the circle with center (-8, -7) and a radius of 6.5.

1 answer:

6 0

The standard equation of a circle is:

(x-h)^2+(y-k)^2=r^2, where r=radius and (h,k) is the center of the circle so:

(x--8)^2+(y--7)=6.5^2

(x+8)^2+(y+7)=42.25

Hawaii 0.288% = what fraction

Sindrei [870]

Answer:

36⁄125 or if we are talking about the lowest term it is 9 /3125

Step-by-step explanation:

Step 1: 0.288 = 288⁄1000

Step 2: Simplify 288⁄1000 = 36⁄125 Percent" or "%" means "out of 100" or "per 100",

<em>Or for the lowest term:</em>

Therefore 0.288% can be written as

0.288

100

Next, we can multiply by

in the form of

1000

to eliminate the decimal in the numerator:

1000

0.288

100

⇒

1000

0.288

1000

100

⇒

288

100000

We can now reduce the fraction as:

288

100000

⇒

3125

⇒

3125

⇒

Which quadrant contains -11pi/18 and what is the reference angle?

vekshin1

Answer:

Option 1 is correct.

Step-by-step explanation:

Given angle $\frac{11\pi}{18}$ . we have to find the quadrant and the reference angle.

Angle given is $\frac{11\pi}{18} i.e \frac{11}{18}\times 180^{\circ}=110^{\circ}$

Hence, the angle is 110° lies in second quadrant.

Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.

which is $\pi-\frac{11\pi}{18}=\frac{7\pi}{18}$

Hence, option 1 is correct.
