Aurora S. thought she had found her true love while vacationing in Italy. To symbolize the "locking of their hearts Aurora and her soulmate
placed a lock on the Ponte Milvio Bridge and threw the key into the Tiber
River. The key left her hand 19.8 meters above the water and had an
initial velocity of 15m/sec. How long was the key in flight before it hit the
water? (round to the nearest hundredth)

5050

hope this !

the answer is 48m^2!

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
