Answer:
(x+9.3)²+(y-4.1)²=169
Step-by-step explanation:
The common equation for a circle in the coordinate plane is:
(x-h)²+(y-k)²=r²
Where (h,k) is the point at the center of the circle and r is the radius:
Here (h,k) is (-9.3, 4.1) and r is 13.
Using this we can substitute to find:
(x-(-9.3))²+(y-(4.1))²=13²
And using arithmetic to simplify we find that the equation of the circle is:
(x+9.3)²+(y-4.1)²=169
the answer is d ( square root 3 )
tan = oposite / adjacent
tan 60° = √3 / 1
= √3
Answer:
7) $57.2 (Multiply 65 by 0.12. You get $7.8. Finally, subtract 7.8 from 65.)
8) $20 (Multiply 29.99 by 0.3333. Subtract 9.99 from 29)
9) $35.7 (Do the same steps as above)
10) $276.675 (Do the same steps as above)
11) The decimal form of 57% is 0.57
12) cost= c×0.57
13) $70.65
14) $25.65 was added
