Answer:

Correct answer:  (x - 10)² + y² = 441 / 4

Step-by-step explanation:

Given:

(a, b) = (10, 0)  the coordinates of the center of the circle

(10, 21/2)  circle passing through this point

The standard form of the circle equation is:

(x - a)² + (y - b)² = r²  where r is radius of the circle

We will replace the given coordinates of the center of the circle and the point it passes through to get the radius of the circle:

(10 - 10)² + (21/2)² = r²  ⇒ r² = (21/2)² = 441 / 4

r² = 441 / 4

(x - 10)² + y² = 441 / 4

God is with you!!!

If the cost of 819.73 for full cover insurance for a female and a male is 1192.64 what is the percentage?
irinina [24]

Answer:

68.7%

Step-by-step explanation:

If the cost of 819.73 for full cover insurance for a female and a male is 1192.64 what is the percentage?

The Percentage is calculated as:

819.73/1192.64 × 100

= 0.68732392004293 × 100

= 68.732392004 %

Approximately = 68.7%

Therefore, the percentage is 68.7%

On your family trip, you used 9 gallons of gas. If the odometer readings before and after your trip were 74,233 and 74,545, resp
sveta [45]

Find the number of miles driven by subtracting the odometer readings:

74545 - 74233 = 312 miles driven.

Divide miles driven by gallons of gas used:

312 / 9 = 34.66 = 35 miles per gallon.

HELP Use either law of sines or law of cosine. Need help on this problem! show work please!​
Marina86 [1]

Answer: x = 15.035677095729 approximately

Round this however you need to.

=================================================

Explanation:

I'm assuming you want to find the value of x, which your diagram is showing to be the length of segment QR.

If so, then we'll need to find the measure of angle Q first. Using the law of sines, we get the following:

sin(Q)/q = sin(R)/r

sin(Q)/PR = sin(R)/PQ

sin(Q)/13 = sin(85)/19

sin(Q) = 13*sin(85)/19

sin(Q) = 0.6816068987

Q = arcsin(0.6816068987) ... or ... Q = 180-arcsin(0.6816068987)

Q = 42.9693397461 ... or ... Q = 137.0306602539

These values are approximate.

----------------

Now if Q = 42.9693397461 approximately, then angle P is

P = 180-Q-R

P = 180-42.9693397461-85

P = 52.0306602539

Similarly, if Q = 137.0306602539 approximately, then,

P = 180-Q-R

P = 180-137.0306602539-85

P = -42.0306602539

A negative angle is not possible, so we'll ignore Q = 137.0306602539

----------------

The only possible value of angle P is approximately P = 52.0306602539

Let's apply the law of sines again to find side p, aka segment QR

sin(P)/p = sin(R)/r

sin(P)/QR = sin(R)/PQ

sin(52.0306602539)/x = sin(85)/19

19*sin(52.0306602539) = x*sin(85)

19*sin(52.0306602539)/sin(85) = x

x = 15.035677095729

This value is approximate.

Round this value however you need to.

I Need help. Thanks.
PIT_PIT [208]

Answer:

A

Step-by-step explanation:

-2(5y-5)-3y\leq -7y+22

Expand parentheses:

-10y+10-3y\leq -7y+22

Move all y's to one side and numbers to the other:

-6y\leq 12

Divide both sides by -6. Since you are dividing both sides by a negative number, you need to flip the comparator:

y\geq -2

Hope this helps!
