Answer:

-10

Step-by-step explanation:

In multiplying and dividing if there is 2 negatives it is always a positive but if it is 1 negative and a positive it is always a negative. This is only for multiplying and dividing. So the answer is negative 10.

In ΔFGH, the measure of ∠H=90°, GF = 53, HG = 28, and FH = 45. What ratio represents the sine of ∠G?
andrew11 [14]

we have been given that in ΔFGH, the measure of ∠H=90°, GF = 53, HG = 28, and FH = 45. We are asked to find the ratio that represents the sine of ∠G.

First of all, we will draw a right triangle using our given information.

We know that sine relates opposite side of right triangle with hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{hypotenuse}}

We can see from the attachment that opposite side to angle G is FH and hypotenuse is GF.

\text{sin}(\angle G)=\frac{FH}{GF}

\text{sin}(\angle G)=\frac{45}{53}

Therefore, the ratio \frac{45}{53} represents the sine of ∠G.

Identify the equation of the circle that has its center at (9, 12) and passes through the origin.
Tcecarenko [31]

Answer:

(x-9)^2 +(y-12)^2 = 225

Step-by-step explanation:

First find the length of the radius

If is the distance from the center to the point

d = sqrt( (x2-x1)^2 + (y2-y1)^2 )

   = sqrt( (0-9)^2 + (0-12)^2)

   = sqrt ( 81+144)

  = sqrt(225)

  = 15

The equation for a circle is

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

(x-9)^2 +(y-12)^2 = 15^2

(x-9)^2 +(y-12)^2 = 225
