Answer: $7.50
The change in her investment after 6 days is $7.50
Imagine the paths as a right triangle with one leg measuring 8 miles and the other 5. You need to find the hypotenuse using the pythagorean theorem, so take 8 squared + 5 squared equals x squared, which gives you 64+25=89, then find the square root of 89 which is 9.433981132
Answer: 55
Explanation: The time that Nicole practiced in 5 WEEKS is 2030 minutes. If you want to know how many minutes she did per DAY, you should first convert 5 weeks into 35 days, since there 7 days in a week. Now, you can divide 35 from 2030, which will give you 55 minutes per DAY.
A.
= (x + 2)^2 - 4 - 11
= (x + 2)^2 - 15
B. vertex is at ( -2, -15) which is a minimum because the coefficient of x^2 is positive.
C. The axis of symmetry is a vertical line passing through the vertex It is
x = -2.
