326/1000 is a different from of .326.
<u>Answer:</u>
<h2>1.393 miles</h2>
<u>Explanation:</u>
320.29 × 7 = 2,242.03 m = 1.39313285413187 miles ≈ 1.393
The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;
- y(x) = - 16x² + 36x + 4
- Height at x = 1.7 = 18.89 feets
<u>The table given</u> :
Time, x : __0.5 ___ 1 ____ 1.5 ____ 2
Height, y _ 18 ____22 ___ 24 ____ 12
<u>Using </u><u>technology</u><u> such as a </u><u>quadratic regression</u><u> calculator or </u><u>excel</u> ;
The quadratic regression model obtained is :
<u>The </u><u>height after, 1.7 seconds</u><u>, x = 1.7 can be calculated thus</u> :
Put x = 1.7 in the equation :
- y(1.7) = - 16(1.7)² + 36(1.7) + 4
- y = 18.89 feets
Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.

Answer:
12
Step-by-step explanation:
15% times 80
80x15%
80 times 15 is 1200
Remember, you always divide by 100 to get your sale price
3 1/2 = 7/2 miles ... 3/4 hour = 3/4 * 60 minutes = 45 minutes
x miles = ? ... 1 minute
y miles = ? ... 1 hour
If you would like to know the number of miles in 1 minute or the number of miles in 1 hour, you can calculate this using the following steps:
7/2 * 1 = 3/4 * y
7/2 = 3/4 * y /*4/3
y = 7/2 * 4/3
y = 14/3 = 4 2/3 miles (per one hour)
7/2 * 1 = 45 * x
7/2 = 45 * x /45
x = 7/2 / 45
x = 7/90 miles (per one minute)
