Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours
The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:
A=A^0⋅(12)^t/h
If Scott was administered 300 mg of Lithium, which of the following represents how much lithium, rounded to the nearest hundredth of a mg, could be left in Scott's blood stream after 12 hours?
Select one:
A. 157.23
B. 106.07
C. 212.17
D. 188.99
Answers
Answer:
B. 106.07
Step-by-step explanation:
To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).
SetupUsing the given formula with the relevant values, we have ...
A = (300 mg)·(1/2)^(12/8)
EvaluationUsing a calculator to evaluate this expression, we find the amount of Lithium remaining in Scott's system after 12 hours to be ...
A ≈ 106.07 mg

Answers
Answer:
40° each
Step-by-step explanation:
The interior angles of a quadrilateral add up to 360°.
360° - 280° = 80°/2 = 40°
How do I solve this: 180° − (45° + 90°)?
Answers
Answer:
180-(45+90)
Step-by-step explanation:
180-(135)
45
Answer is 45
Answer:
45°
Step-by-step explanation:
→ First solve the values within the brackets
45° + 90° = 135°
→ Resubstitute back
180° - 135°
→ Solve

The distance that a object covered in time was measured and recorded in the table. What equation would describe this motion?
y = 2x
y = 4x + 2.5
y = 4x + 4
y = 1.5x + 4.0
Answers
Answer:y = 1.5x + 4.0
Step-by-step explanation:
This is because the equation relates the distance traveled (y) to the time elapsed (x) through a linear relationship with a slope of 1.5, which represents the object's speed in meters per second, and a y-intercept of 4.0 meters, which represents the initial position of the object at time zero.
I'm pretty sure.
The equation that describes the motion of the object is y = 2x (option a)
Let's calculate the slope (m) using the values from the table. We take any two points (x₁, y₁) and (x₂, y₂) from the table:
(x₁, y₁) = (1, 2.0)
(x₂, y₂) = (5, 10.0)
The slope (m) is given by:
m = (y₂ - y₁) / (x₂ - x₁)
m = (10.0 - 2.0) / (5 - 1)
m = 8.0 / 4
m = 2.0
Now that we have the slope (m), we can determine the equation:
y = mx + b
Using one of the points from the table (1, 2.0) and the calculated slope (m = 2.0), we can solve for the y-intercept (b):
2.0 = 2.0 * 1 + b
2.0 = 2.0 + b
b = 2.0 - 2.0
b = 0
So, the Answer is option (a) y = 2x

13. B) Non-linear
As per its definition, linear means line. If a function is linear, then one can plot it out, and the resulting graph will be a line. This is not the case for the given function, therefore, it is non-linear.
14. A) Yes
An outlier is a data point that does not fit in with the result. It is not in the general region that the rest of the data points fall in. In the given function, the point (0.5, 3) is not in the general region that the rest of the points are in, therefore, it is an outlier.
15. B) Yes, there seems to be two distinct groups of data.
As one can see there appears two be two groups of data. One of them is towards the upper left corner, whereas the other seems to be towards the lower right corner.

Matthew filled up the gas tank just once.
Write an equation to represent the situation.

Answer: 2x + 15 = 243
x = $114
Step-by-step explanation:

you are given 2 supplementary angles.one has a measure of 4x and the other has a measure of 8x. what is x?
Answers
Answer:
x=15
Step-by-step explanation:
Supplementary angles are two angles that equal the sum of 180 degrees.
Take 4x and 8x and make it equal to 180
4x+8x=180
Add like terms:
12x=180
Divide:
x=15
To check:
Plug in 15 to both expressions
4(15)=60
8(15)=120
Add them up and they equal 180 degrees
