Step-by-step explanation:

E = m/2g(v²-u²)

2g×E = 2g×m/2g(v²-u²)

2Eg = m(v²-u²)

2Eg = mv² - mu²

mu²= mv² -2Eg

mu²/m = mv² -2Eg /m

u²= v² -2Eg

u = √v²-√2Eg

Write an equation for the line parallel to the given line that contains <br> C(4,8);y=-3x+4

Brrunno [24]

Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20

The answer is y = -3x + 20

An emergency room doctor prescribes a certain pain medication to be delivered through an IV drip. She prescribes 800 mL of the

Keith_Richards [23]

Answer:

The number of drips per minute needed to deliver the medication at the prescribed dosage is 50 drips per minute

Step-by-step explanation:

The given parameters are;

The volume of the prescribed medication to delivered through IV = 800 mL

The duration over which the drug is to be delivered = 8 hours

The rate at which the IV delivers the medication = 30 drips/1 mL

800 mL = 800 × 1 mL

Therefore, the total number of drips in 800 mL= 800 mL × 30 drips/mL = 24,000 drips

The rate at which the drug is delivered = 800 mL/(8 hours) = 100 mL/hr = 100/60 mL/minute = 10/6 mL/minute

The total number of drips in 10/6 mL= 10/6 mL × 30 drips/mL = 50 drips

∴ The rate at which the medication needs to be delivered = 10/6 mL/minute = 50 drips/minute

The number of drips per minute needed to deliver the medication at the prescribed dosage of 800 mL/(8 hours) = 10/6 mL/minute = 50 drips per minute.

Mito bakes biscuits. he uses 1/4 cup of flour to coat the countertop and the rolling pin. He also uses 2 1/2 cups of flour for e

Gennadij [26K]

Answer:

Mito can bake 3 batches of cookies.

The amount of flour used to bake cookies = Total flour used - Amount of flour used to coven counter top.

Step-by-step explanation:

Here, the amount of flour used to coat counter top and rolling pin = 1/4 cup

1/4 cup = 0.25 cup

Now, the amount of cup used to bake 1 batch of cookies = 2 1/2 cup

Now, 2 1/2 cup = ( 2 + 1/2 )cup = 2 + 0.5 = 2.5 cup

So, 1 batch of cookies = 2.5 cup

Total amount of flour used = 7 3/4 cups

Now, 7 3/4 cup = (7 + 3/4) cup = 7 + 0.75 = 7.75 cups

The actual amount of flour used to bake cookies

= Total flour used - Amount of flour used to coven counter top.

= 7.75 cup - 0.25 cup = 7.5 cup

Now, the number of batches baked with 7.5 cup $= \frac{\textrm{Total amount of flour used in baking}}{\textrm{Flour used in 1 batch}}$

$= \frac{7.5}{2.5} = 3$

or, the number of batches baked with 7.5 cup is 3 batches.

Hence, Mito can bake 3 batches of cookies.
