Please help 50 points: A ball is thrown straight up, from 3 m above the ground, with a velocity of 14m/s. When does it hit the ground? Use vertical motion formula.

Answers

Answer 1

Answer:

3.058s

Step-by-step explanation:

i cant rewrite everything i solve in the paper sorry

Answer 2

Step-by-step explanation:

In this question, to find the total height first, we must also take into consideration the acceleration due to gravity as well. To find the distance by which acceleration due to gravity pulls the ball down must know the Initial velocity.

In the answer key, it says that gravity changes the ball's height by a distance of -5t^2

Is initial velocity in this question 0 or 14m/s? Because if it is 14, then gravity should change the balls position by -(14+5t^2), not -5t^2, because if I remember correctly, the formula for finding distance is vt(initial velocity)+(1/2)at^2 ,and not just (1/2)at^2

Function A(e) represents the surface area of a cube in terms of its edge length, e, and the difference quotient is 12e + 6h. What is the average rate of change in surface area of a cube as the edge length increases from 3 inches to 5 inches?

48 square inches per inch
54 square inches per inch
66 square inches per inch
96 square inches per inch

Answers

Answer: 48 square inches per inch

Step-by-step explanation:

The surface area of a cube of sidelength e is:

A(e) = 6*e^2.

The rate of change is:

A'(e) = 2*6*e

The average rate of change between 3 in and 5 in is:

r  = (A(5in) + A(3in))/2 = (2*6*5in + 2*6*3in)/2 = 48in

Now, the options are given in:

"squere inches per inch"

This is written as:

in^2/in = in.

Then we can write our above rate as:

r = 48in = 48in^2/in = 48 square inches per inch.

Answer:

Just did the test, 48 square inches is correct on edge

Answers

Answer:

5.25/25=0.21

Step-by-step explanation:

to find this you can do 0.21 times 25 which gets 5.25 so there is your answer

5.25/25=0.21 is the unit price per​ card.

What is division?

Division is the process of splitting a number or an amount into equal parts.

Here, given that,

A store sells a package of 25 trading cards for​ $5.25.

So, price of per card = 5.25/25

                                  =0.21

(to find this you can do 0.21 times 25 which gets 5.25 )

Hence, 0.21 is the unit price per​ card.

Often we need to use exponents to correctly model the variation in situations:
The volume of a cylinder varies jointly with the square of its radius and its height. Its
general equation looks like V = kr’h where k= some constant number for all cylinders
and V, rand h are variables representing volume, radius and height, respectively. When
the radius is 3 cm and height is 5 cm, the cylinder has a volume of 141.3 cm. Find the
volume when the radius is 6 cm and the height is 10 cm.

Answers

Answer:

V = 1130.4 cm³

Step-by-step explanation:

Given that V varies jointly with r² and h then the equation relating them is

V = kr²h ← k is the constant of variation

To find k use the condition when r = 3 and h = 5 then V = 141.3 , then

141.3 = k × 3² × 5 = 45k ( divide both sides by 45 )

k = 3.14 ← note approximation for π

V = 3.14r²h ← equation of variation

When r = 6 and h = 10, then

V = 3.14 × 6² × 10 = 3.14 × 36 × 10 = 1130.4 cm³

Sharon has two liabilities: a credit card balance of $1300 and a car loan balance of $4800. Sharon car has a market value of $9000 she also has a balance of $1450 in her saving account and has stocks that are currently worth $1050. What is Sharon’s net worth?

Answers

Given:

Sharon has two liabilities: a credit card balance of $1300 and a car loan balance of $4800.

Car = $9000

Balance in her saving account = $1450

Stocks = $1050.

To find:

Sharon’s net worth.

Solution:

Total liabilities = Credit card balance + Car loan balance

                        = $1300 + $4800

                        = $6100

Total Assets = Car + Balance in her saving account + Stocks

                     = $9000 + $1450 + $1050

                     = $11500

Now,

Net worth = Total assets - Total liabilities

                 = $11500 - $6100

                = $5400

Therefore, Sharon’s net worth is $5400.

Sharon's net worth, based on her assets and liabilities, is $5,400.

What is the net worth?

Net worth refers to the difference between an individual's assets and liabilities.

Assets are the properties owned by the individual.  Liabilities are the sources of funding for the assets.  They are financial obligations owed to outsiders (creditors).

In business, the net worth of an entity is known as equity.

Data and Calculations:Liabilities:

Credit card balance of $1300

Car loan balance of $4800

Total liabilities = $6,100

Assets:

Sharon's car with a market value of $9000

Savings account balance of $1450

Stocks that are currently worth $1050

Total assets = $11,500

Net worth = $5,400 ($11,500 - $6,100)

Thus, Sharon's net worth is $5,400.
