Zach throws a ball upward so that it follows the equation y = -16x² + 64x + 5 where y is the height of the ball
and x is time. How many seconds until the ball reaches its maximum height? Hint: look at its table. (Help ASAP pls)

sine

step-by-step explanation:

plz mark brainliest i took the test

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.

1. for division, flip the second fraction.

2. factor the numerator and denominator completely.

3. divide out common factors.

4. multiply the simplified fractions.
