The center of a circle is at (–10, 6) and it has a radius of 4. what is the equation of the circle? question 9 options: (x – 10)2 + (y + 6)2 = 2 (x – 10)2 + (y + 6)2 = 16 (x + 10)2 + (y – 6)2 = 2 (x + 10)2 + (y – 6)2 = 16 the equation x2 + (y + 3)2 = 36 models the boundary on a local map for which darren can hear his friend tom on his two-way radio when darren is at home. how far (in miles) can tom walk from darren's home and still be heard? question 11 options: 3 miles 6 miles 2 miles 12 miles

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
