You are indeed correct good job!
Answer:
6 miles on the first day and 14 miles on the second day
Step-by-step explanation:
The scale factor changes by 1/8.
The numerator, 1 stays the same; the denominator changes. 16/2 = 8; it is 1/8 the scale of the previous scale.
Our fathers brought forth on this continent a new nation.
f(x)= x^2 -6x +21
0 =x^2-6x+21
subtract 21 from each side to prepare for completing the square
-21 = x^2 -6x
completing the square (b/2)^2
(-6/2) ^ =3^2 = 9
add 9 to each side
-21 +9 = x^2 - 6x + 9
-21 +9 =(x-3) ^2
-12 = (x-3)^2
take the square root of each side
+- sqrt(-12) = x-3
add 3 to each side, take out the negative inside the square root
3 +- i sqrt(12)=x
simplify the square root sqrt(12)= sqrt(4)sqrt(3) =2sqrt(3)
3 +- i 2sqrt (3) = x
Answer: 3+2isqrt(3)
3-2isqrt(3)
