Answer:
1) 0.16 mg of pure heparin is in 80 Howell units
2) the loading dose, in mg of heparin for the 5-year-old boy is 2.618 mg
Step-by-step explanation:
Given that;
if a patient is less than 70 years of age then loading dose is 80 Howell units square per Kg of DM,
One Howell unit is equivalent to 0.0020 mg of pure heparin
1)
how many mg of pure heparin is in 80 Howell units.
that will be;
80 × 0.0020 = 0.16 mg
therefore 0.16 mg of pure heparin is in 80 Howell units
2)
First we find the dosing mass
so dosing mass = body weight of the 5year old boy × 90%
from the question his total body weight of 40 lbs and 1 kg = 2.20 lbs
so
dosing mass = 40lbs × 1kg/2.20lbs × 90/100
dosing mass(kg) = 16.37 kg
Now to calculate the Loading dose we say;
Loading dose = dosing mass × heparin required per kg
Loading dose = 16.36 kg × 0.16 mg heparin per 1kg
loading dose = 2.618 mg heparin
therefore the loading dose, in mg of heparin for the 5-year-old boy is 2.618 mg

Samara Park gets $0.25 for each pound of apricots she dries. How much will she be paid if she dries 16.4 pounds?
Samara will be paid $4.10 for drying 16.4 pounds of apricots.
How to calculate payment?To calculate the payment for the purchase of the item, we can use the formula:
Payment = Rate × Amount
Here, the rate is the amount paid per pound and the amount is the total number of pounds item.
To calculate Samara's payment for drying apricots, we can use the formula:
Payment = Rate × Amount
As per the question, the rate is $0.25 per pound, and the amount is 16.4 pounds.
So, substitute these values into the formula:
Payment = $0.25 × 16.4
Multiply $0.25 by 16.4:
Payment = $4.10
Therefore, Samara will be paid $4.10 for drying 16.4 pounds of apricots.

Solve for y in terms of x. Determine if y is a function of x. If it is, rewrite using f(x) notation. If not, enter ND in the answer field.
7x-5y=2
Answer:
y = (7x-2)/5Step-by-step explanation:
Given the expression 7x-5y = 2, we are to write y in terms of x. to do that, we will have to make y the subject of the formula from the given expression as shown;
7x-5y = 2
subtract 7x from both sides of the equation
7x-5y-7x = 2-7x
-5y = 2-7x
Multiply through by minus sign
-(-5y) = -(2-7x)
5y = -2+7x
5y = 7x-2
Divide both side by 5;
5y/5 = (7x-2)/5
y = (7x-2)/5
Hence the expression y as a function of x is given as y = (7x-2)/5

Solve each system of equations of equations.
x + y = -6
2x - y = 3
Answer:
x = -1, y = -5
Step-by-step explanation:
x + y = -6
2x - y = 3
Add the two equations together to eliminate y
x + y = -6
2x - y = 3
------------------
3x = -3
Divide by 3
3x/3 = -3/3
x = -1
Now find y
x+y = -6
-1+y = -6
Add 1 to each side
-1+1 +y = -6+1
y = -5
There is a number such that four times the number plus 3 is equal to 19. Find the number.
An equation is formed of two equal expressions. The number is 4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that there is a number such that four times the number plus 3 is equal to 19.
Let the number be M.
Given that there is a number such that four times the number plus 3 is equal to 19. Therefore, We can write it as,
4M + 3 = 19
Now, we can write,
4M + 3 = 19
Subtract 3 on both sides
4M + 3 - 3 = 19 - 3
4M = 16
Divide both sides by 4,
4/4 M = 16/4
M = 4
Thus, the number is 4.

Use the ogive to approximate (a) the number in the sample, (b) the location of the greatest increase in frequency.
Answer:
Step-by-step explanation:
A). Number of samples given in the ogive = Number of points given n the graph
Number of points plotted on the graph = 16
Therefore, number of samples given = 16
B). Frequency at a point where weight of the pumpkins is 23.5 = 10
Frequency at a point where weight of the pumpkin is 24.5 = 23
Increase in frequency = 23 - 10 = 13
None other points have the increase more than the given points.
Location of the greatest increase in the frequency is between the weights 23.5 - 24.5 pounds.
The number of samples is 16, and the location of greatest increase in frequency is 23.5 to 24.5.
We are provided with an ogive curve. In the x-axis, we have weight in pounds and y-axis represents frequency.
(a).
Now, the number of points on the ogive represents the number of sample.
So, the number of points on the curve is 16 which is also the number of samples.
(b).
The greatest increase in frequency is represented in the range 23.5 to 24.5.
The greatest hike in frequency is about 10.
Therefore, the number of samples is 16, and the location of greatest increase in frequency is 23.5 to 24.5.

write the equation of the parabola in vertex form vertex (0,0) passes through (2,1)
Answer:
[tex]f(x)=\frac{1}{4}x^2[/tex]
Step-by-step explanation:
Recall the vertex form of a quadratic equation:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h,k) is the vertex.
We are told that the vertex is (0,0). Therefore:
[tex]f(x)=a(x-0)^2+(0)[/tex]
Simplify:
[tex]f(x)=ax^2[/tex]
So, to finish the equation, we need to find a.
We know that a point is (2,1). Thus, substitute 1 for f(x) and 2 for x:
[tex]1=a(2)^2[/tex]
Square:
[tex]1=4a[/tex]
Divide both sides by 4:
[tex]a=\frac{1}{4}[/tex]
So, our a value is 1/4.
And we can thus complete our equation:
[tex]f(x)=\frac{1}{4}x^2[/tex]

Now, look at the set of integers. Complete the table for the closure property if integers under the four operations.
Answer:
See below.
Step-by-step explanation:
Addition: closed
Example: -5 + 10 = 5, and -5, 10, and 5 are all integers
Subtraction: closed
Example: 10 - 8 = 2, and 10, 8, and 2 are all integers
Multiplication: closed
Example: -4 * 7 = -28, and -4, -7 and -28 are all integers
Division: not closed
Example: 5/2 = 2.5, and 2.5 is not an integer, although 2 and 5 are integers
The set of integers is closed under addition, subtraction, and multiplication because any addition, subtraction, or multiplication of integers always results in an integer.
The set of integers is not closed under division because a division of integers does not always result in an integer.

A 12-ft ladder leaning against a house makes a 64 degree angle with the ground. Will the ladder reach a window sill that is 10.5 ft up from the base of the house?
Answer:
Yes, it will
Step-by-step explanation:
Given
Length of Ladder = 12 ft
Angle = 64
Required
Determine if it'll reach a height of 10.5ft from the base
See attachment for proper illustration.
From the attachment, we want to determine that x be greater than 10.5
Using sin formula:
[tex]Sin\ 64 = \frac{x}{12}[/tex]
Multiply through by 12
[tex]x = 12 * sin\ 64[/tex]
[tex]x = 12 * 0.8988[/tex]
[tex]x = 10.79[/tex] (Approximated)
Since 10.79 is greater than 10.5, then the ladder will reach the window
sin64 = x/12
x = 12* sin64
