Answer:

60ft/s

Step-by-step explanation:

To find the rate

rate = f(3) - f(0)

         -------------

         3-0

rate = 200-380

         ---------------

         3-0

rate = -180/3   = -60 ft/s

The negative tells us it is falling

The fall falls 60ft/s

<u>Answer:</u>

The correct answer is 60 feet / second.

<u>Step-by-step explanation:</u>

We are given the height of a ball which is falling from a height of 280 feet for 3 seconds.

We are to find the ball's rate of fall during the first 3 seconds.

For that, we will take the difference between the heights and divide it by the time.

Ball's rate = \frac { 3 8 0 - 2 0 0 } { 3 } = 60 feet / second

Svetlanka [38]

You have two choices: the easiest is to turn every fraction to its numerical equivalent:

-\dfrac{9}{10}=-0.9,\ \ -\dfrac{3}{7}\approx -0.42857,\ \ -\dfrac{3}{4}=-0.75,\ \ -\dfrac{6}{5} = -1.2, -\dfrac{4}{3}\approx -1.33

Now, remember that negative numbers are ordered in the opposite way with respect to positive numbers (for example, 4 is larger than 2, but -4 is smaller than -2). So, the order is

-\dfrac{4}{3} < -\dfrac{6}{5} < -\dfrac{9}{10} < -\dfrac{3}{4} < -\dfrac{3}{7}

Alternatively, you can convert all the fractions so that they have the same denominator. In this case, you will need the least common multiple of 10, 7, 4, 5 and 3, which is 420. Once you do so, you can easily order the fractions using numerators only.

olutions At the snack bar, hot dogs cost $4 each and bottled water costs $2 each. In the first business hour of the day, less th
ch4aika [34]

To solve the problem it is trial and error since we don’t know how many hotdogs and bottled water was sold. To trim down to problem, negative values and decimal values are not included because there is no negative amount and a decimal amount.

The equation is

4x + 2y > 12

At (0,6)

4(0) + 2(6) > 12

12 > 12 so it is wrong

At ( 2,1)

4(2) + 2(1) > 12

10 > 12 correct

At (1, 3)

4(1) + 2(3) > 12

10 > 12 correct

At (2,2)

4(2) + 2(2) > 12

12> 12 wrong

I would go with 12.5

I’m more of an English person but that’s my best guess.

3/24
1/8
1 divided by 8
=12.5

Hope you get it right :)

Answer:

if you want to factorise it answer will be : (x+y)^2 - 4^2

and if you have to expand it anwer will be x^2 + y^2 + 2xy -16
