Thank you!

1. A boat costs $ 10,450 and reduces the value by 5% per year. What is the ship of the sentence after 14 years?

2. Determine the domain of y = 4 √ 4x 2

3. A map has a scale of 1 cm: 12 km. Two cities are 2.1 cm apart on the map. One-tenth of a mile, which is the actual distance, the distance on the map?

4. Use the simple interest formula, I = prt. Find if p = $ 158.14, r = 1.1%, T = 3 years.

5. Suppose you choose a marble in a bag containing 6 red balls, 3 white balls and 4 blue balls. To reduce the marble for the first bag, then choose again. Find P () red and blue.

6. The value of n, such that x2 - 17x + n is a square trinomial

7. Use the quadratic formula to solve the equation. If necessary for you to the nearest hundredth

8. The time t required to drive a certain distance is inversely proportional to the amount of r. If it takes 3 hours by car away from 45 miles per hour, how long itt to drive the same distance of 25 miles per hour?


Thank you sooo much:)
