Awatermelon is dropped from the tenth story of a building. solve the equation −16t2+144=0 for t to find the number of seconds it takes the watermelon to reach the ground.

ANSWER:  

Water melon takes 3 seconds to reach the ground from the tenth story of a building.

SOLUTION:

Given, a watermelon is dropped from the tenth story of a building.  

We have to solve the equation −16 + 144 = 0 for t to find the number of seconds it takes the watermelon to reach the ground.

Now consider the given equation,

Hence, water melon takes 3 seconds to reach the ground from the tenth story of a building.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
