The physician orders 3 mg/kg of medication twice a day. The patient’s weight is 315 lb. How much medication does the patient receive each day?
Answer: To find out how much medication the patient receives each day, you need to determine the patient's weight in kilograms and then calculate the total dosage per day.
You can convert the patient's weight from pounds (lb) to kilograms (kg) by dividing the weight by 2.2.
So,
315/2.2 = 142.72 kg
Next, we can use this weight to determine the dosage per day:
3 mg/kg * 142.72 kg = 428.16 mg
Now, since the physician ordered twice a day, we will multiply the dosage per day with 2:
428.16 mg * 2 = 856.32 mg
So the patient receives 856.32 mg of medication each day.

Given P(x) = 2x3+ 3x2- x + 4, find P(0) and P(-2).
9514 1404 393
Answer:
P(0) = 4
P(-2) = 2
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
P(0) = 2·0³ +3·0² -0 +4
P(0) = 4
__
P(-2) = 2·(-2)³ +3·(-2)² -(-2) +4 = 2(-8) +3(4) +2 +4
P(-2) = -16 +12 +2 +4
P(-2) = 2

Answer:
2000 workers
Step-by-step explanation:
All the workers: 100%
Women: 60%
Others: 40% = 800 workers
=> 1% of the workers: 800/40 = 20 workers
=> 100% = 20 x 100 = 2000 workers

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 24 inches, and the length of the base is 11 inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.
Answer: 60.2 inches
The perimeter of the triangle is 80.24 inches.
What is Pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
Altitude = 24 inches
Base = 11 inches
Half of the base = 11/2 = 5.5 inches
Using Pythagoras theorem:
Hypotenuse = √(24² + 5.5²)
Hypotenuse = √(576+ 30.25)
= √606.25
= 34.62 inches
Now, perimeter of a triangle
= (base + side 1 + side 2)
= (11 + 34.62+ 34.62)
= 80.24 inches
Hence, the perimeter of the triangle is 80.24 inches.

3. At practice the team wants to know how fast Ryan can skate. He skates 10 laps around the
rink in 3 minutes and, later on in practice he skates 5 laps in 1 minute. What was his
average speed in laps per minute?
The average speed in laps per minute of Ryan is 2.5 laps per minute
How to determine the average speed in laps per minute?From the question, we have the following parameters that can be used in our computation:
He skates 10 laps around the rink in 3 minutes In practice he skates 5 laps in 1 minuteThe above can be expressed as
(x, y) = (1, 5) and (3, 10)
The average speed in laps per minute can be calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Rewrite as
Average speed = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (1, 5) and (3, 10)
Substitute the known values in the above equation
So, we have the following equation
Average speed = (10 - 5)/(3 - 1)
Evaluate
Average speed = 2.5
Hence, the average speed is 2.5

Find the length of the model in the picture!!!Then find the scale factor.The length of an actual bird is shown on the picture.
We calculated length of model bird in the picture = 2 ¹⁵₁₆ inch and scale factor =1/2
what is scale factor?
It is expressed as the ratio of the dimension of a model object and dimension of an actual object.
A scale factor is a number which is multiplied by an object in order to form a proportional enlarged or reduced object.
What is the length of the model in the picture?Given, the length of an actual bird = 5⁷₈ inch = 47/8 inch
also given, 1 inch = 0.5 inch
1 inch = 1/2 inch
we need to determine the length of model bird by multiplying the above factor.
now, length of model bird = 47/8 × 0.5 inch = 47/16 inch = 2¹⁵₁₆ inch
scale factor = length of model bird/ length of actual bird = 47/16 /47/8
scale factor = 1/2

If a vehicle is going 75 mph, how many feet does it travel in one second?
Answer:
How many feet does a car travel in 1 second if it is moving at a rate of 75 mph? So you're going 110 ft per second. In other words, the car travels 110 feet in 1 second (and does so each second assuming you maintain the speed of 75 mph).
The distance (in feet) travelled by the car moving at 75 mph in one second is 110 feet
What is speed?Speed is the distance travelled per unit time. Mathematically, it can be expressed as:
Speed = distance / time
How to convert 75 mph to feet per second (fps)1 mph = 1.467 fps
Therefore,
75 mph = 75 × 1.467
75 mph = 110.025 fps

F(x)=2x^3+2x-3 g(x)=-.5[x-4] what is the y value when f(x) = g(x)?
Answer:
D. x = 0.5
Step-by-step explanation:
A graphing calculator is the quickest way to get to an answer here.
f(x) = g(x) for x = 0.5
__
We can find the y-intercepts of the two functions to be ...
f(0) = -3
g(0) = -2
We know the x-intercept of g(x) is x=4. The x-intercept of f(x) will be a value less than 1, because f(1) = 1. (The function crosses the x-axis between x=0 where f(x) < 0 and x=1, where f(x) > 0.)
Considering these intercept points, we know the value of x for f(x)=g(x) will be between x=0 and x=1. There is only one answer choice in that interval:
x = 0.5

Algebra: What Is It?Algebra, a subfield of mathematics, is concerned with symbols and the mathematical operations carried out on them. Because these symbols don't have predetermined values, they are referred to as variables. These symbols are additionally put through a variety of addition, subtraction, multiplication, and division arithmetic operations in order to obtain the values.
Here,
Given: actual flower bed: 18
This represents 30% of all garden beds.
Assume that x is the size of the entire flowerbed.
