Answer:
Center is (7,-6)
Our radius is 4
Step-by-step explanation:
Subtract 69 to both sides
Complete the square of the x terms and y terms.


(To complete the square divide the coefficient by 2 and square it).


Add those terms to the full equation. Add 36 and 49 to the right side as well

Simplify the x and y terms into a binomial.

Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.






So our center is (-7,6)
Our radius is 4.

Answer:
The secant of the angle equals the distance between the ants divided by the distance from the first ant to the wall, So sec 62° = d / 1, where d is the distance between the ants. That's more than the hearing range of 2m, so yes, the friend will be a meal. Step-by-step explanation:
Answer:
( 8,11)
Step-by-step explanation:
When x = 8 the output is 7
The new function
f(x) +4
when x = 8
The output is f(8) +4= 7+4 = 11
( 8,11)
Answer:
Definition of Midpoint
Step-by-step explanation:
Say RS is 20(as an example), that would make RT 10 and TS 10. The two halves of the midpoint are congruent.
