Step-by-step explanation:
Equation of a circle in standard form is given as:
![(x - h)^{2} + (y - k)^{2} = {r}^{2} \\ \\ \therefore \{x -( - 4) \}^{2} + (y - 6)^{2} = {7}^{2} \\ \\ \red{ \boxed{ \bold{\therefore (x + 4)^{2} + (y - 6)^{2} = 49}}} \\ is \: the \: required \: equation \: of \: circle.](https://tex.z-dn.net/?f=%28x%20-%20h%29%5E%7B2%7D%20%20%2B%20%28y%20-%20k%29%5E%7B2%7D%20%20%20%3D%20%20%7Br%7D%5E%7B2%7D%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%20%5C%7Bx%20-%28%20-%204%29%20%5C%7D%5E%7B2%7D%20%20%2B%20%28y%20-%206%29%5E%7B2%7D%20%20%20%3D%20%20%7B7%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cred%7B%20%5Cboxed%7B%20%5Cbold%7B%5Ctherefore%20%20%28x%20%20%2B%20%204%29%5E%7B2%7D%20%20%2B%20%28y%20-%206%29%5E%7B2%7D%20%20%20%3D%2049%7D%7D%7D%20%5C%5C%20is%20%5C%3A%20the%20%5C%3A%20required%20%5C%3A%20equation%20%5C%3A%20of%20%5C%3A%20circle.)
Answer:
scale factor= 4.7
Step-by-step explanation:
47/10= 4.7
32.9/7= 4.7
28.2/6= 4.7
To figure out the scale factor for the smallest to the largest triangle, divide the larger number by the smaller number (of the same side).
If you wanted to get the scale factor of the largest to smallest triangle, you would just do the opposite.
ex. 10/47, 7/32.9...
We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us with 27.75 and a shirt cost 14 and 50 cent .
SO you need to divide 27.75 in 14 and 50 cents which is equal to
14 plus 14 equals 28
75 plus 50 equals 1 and 25 cents

The two variables are time (x) and distance (y)
And the answer is they will meet after 1 mile
The function of the aunt and uncle is y=25x+5
The function of yourself is y2=30x
Since you want to know when you’ll meet, you just resolve y=y2 or 25x+5=30x
Wich will be x=1 so 1 mile
