Answer: 5.6 miles per hour
Step-by-step explanation:
Answer:
the center is (-4,7) and the radius is 3
Step-by-step explanation:
The center of a circle can be found using the equation
and is (h,k) from it. Notice h and k are the opposite value as in the equation.
First write the equation in this form.
Complete the square with each variable to find what numbers should go in place of the question marks.
Add 16 and 49 to both sides of the equation.
So the center is (-4,7) and the radius is 3.
First, X^2 while x is 4 =4^2, which is 4x4, which is 16
3X while x is 4 is 12. 16-12=4. So the answer is 4
The angle would be obtuse. So it would be over a 90* angle.
•1= 30*
•2= 60*
•3=90*
•4=120*
•5=150*
•6=180*
•7=210
•8=230*
