Answer: 1.41 seconds

Step-by-step explanation:

The problem gives the initial velocity by saying "dropped." This indicates a velocity of zero. Acceleration can also be found because the object is in free fall. It would experience the acceleration of gravity. We can use the kinematic equation:

(y_f-y_i)=V_it+\frac{1}{2}at^2

The velocity term completely cancels because the object was dropped with an initial velocity of 0.

(18-50)=\frac{1}{2} (32.17)t^2\\

-32=-16.085t^2\\t=\sqrt{1.989} =1.41s

Mr. Lee left his fortune to his 3 sons, 4 daughters and his wife. Each son received twice as much as each daughter and his wife
ivolga24 [154]

Hey there! :)

Answer:

$3600.

Step-by-step explanation:

If the wife received $6000 which is a quarter of the money, solve for the total amount of the fortune:

1/4x = 6000

Multiply both sides by 4:

x = $24000

We can begin by subtracting the wife's amount from the total:

24000 - 6000 = $18000

He has 3 sons and 4 daughters. Let 'x' represent the amount the daughters received, and '2x' the amount the sons received.

18000 = 3(2x) + 4(x)

Distribute and combine the terms:

18000 = 6x + 4x

18000 = 10x

Divide both sides by 10:

18000/10 = 10x/10

x = $1800. This is the amount that each daughter receives. Since the sons receive '2x':

2(1800) = $3600.

What is the inverse of y=cos(x-pi/2)​?
alekssr [168]

Answer:

f − 1 ( x ) = arccos  ( x ) +  π/ 2

Step-by-step explanation:

y=cos(x-pi/2)

For inverse, interchange the variables and solve for y

f − 1 ( x ) = arccos  ( x ) +  π/ 2

A shop rents a DVD player at $10 per day and a charged a later fee of $15 for every day it is late. If Timmy renter a DVD player
Assoli18 [71]

Answer:

$130

Step-by-step explanation:

Renting the dvd for one day costs $10.

$15 is charged for every late day .

Timmy rented the DVD player for 4 days and returned it 10 days later.

For 4 days , the amount

= $10 x 4

= $40

For the remaining six days he’ll pay

$15 x 6= $90 because he was charged the late fee .

Therefore, total amount paid by Trimmy

= $40 + $90

= $130

Trimmy paid $130
