Jayce is a taxi driver.
M(n) models Jayce's fee (in dollars) for his nth drive on a certain day.
What does the statement M(10) = K mean?
Choose 1 answer:
A
Jayce's fee for his Kth drive is equal to $10.
(B)
Jayce's fee for his 10th drive is equal to K dollars.
Answers
The correct answer is C. Jayce's fee for his 10th drive is equal to K dollars.
Based on the mentioned statements, n refers to the number of drives in a certain day. Additionally, it is mentioned that M(n) models the fee in dollars. As is seen in the equation, M(n) is equal to K. Thus, the fee in dollars is K dollars.
Now, as n is ten, thus the drive is tenth. And the fees for tenth drive is K dollars. So, the third option is correct, which states that Jayce's fee for his tenth drive is equal to K dollars.

Equation:
(b) Find y when x = 5.
OC
Answers
Answer:
A. y = -4x
B. y = 20
Step-by-step explanation:
A. y = xk
Where k is constant
Substitute y for -8 and x for 2
-8 = 2k
Divide both sides by 2
-8/2 = 2k/2
-4 = k
k = -4
y = x(-4)
y = -4x
B. y when x = 5

A line passes through the point (-8,-3) and has a slope of -3/4
Answers
The equation of the line that passes through the point (-8,-3) and has a slope of -3/4 is y = -3/4x - 9
How to determine the equation of the line?From the question, we have the following parameters that can be used in our computation:
Slope, m = -3/4
Points, (x₁, y₁) = (-8, -3)
A linear equation can be represented as
y = slope * x + y-intercept i.e. y = m(x - x₁) + y₁
Substitute the known values in the above equation
So, we have the following equation
y = -3/4(x + 8) - 3
Open the brackets
So, we have the following equation
y = -3/4x - 6 - 3
Evaluate the like terms in the above equation
So, we have the following representation
y = -3/4x - 9
The above equation cannot be further simplified
Hence. the linear equation is y = -3/4x - 9

Answers
A bit string of length 5 contains 2^5 = 32 potential values because each bit has two possible values.
The quantity of bits in a bit string determines its length. When the bit string is produced, this precise non-negative integer is fixed. The exact non-negative integers that are smaller than the bit string's length are the valid indexes. Bit strings can have zero bits or more. A series of bits is known as a bit string. Bit strings can be used to modify binary data or represent sets. In right to left order, a bit string's elements are numbered from zero to the number of bits in the string minus one.

a 61 mg of a vaccine is given to a patient to prevent measles. the vaccine leaves the body at a rate of 6.1% per hour. define a function g that gives the mass of the vaccine remaining in the body, v, in terms of the number of hours, n since the vaccine was administered. how much of the vaccine remains in the body 24 hours after it was administered? mg use your graphing calculator to determine how many hours passed before there were only 5mg of the vaccine remaining in the body.
Answers
The linear equation that represent the amount vaccine that remain is g = 61 - 0.061n. The vaccine remains in the body 24 hours after it was administered 59.536 mg. There were only 5mg of the vaccine remaining in the body after 918.033 hours.
What is rate?
A rate is a unique ratio where the two words are expressed in several units.
Given that the amount of vaccine is 61 mg.
The vaccine leaves the body at a rate of 6.1% per hour.
After 1 hour the body will consume 6.1% = 6.1/100 = 0.061 mg.
After n hour the body will consume 6.1%× n = 0.061n mg.
The remaining amount of vaccine is (61 - 0.061n).
The required linear equation that represent the remaining amount of vaccine is g = 61 - 0.061n.
Putting n =24 in the equation:
g = 61 - 0.061×24
g = 59.536 mg
The vaccine remains in the body 24 hours after it was administered 59.536 mg.
The graph represents that there were only 5mg of the vaccine remaining in the body after 918.033 hours.

Sam has had five quizzes so far in his class. His average score is 74%. He
scored a 99% on his sixth quiz. What is his average now? Round to a whole
number.
Answers
Sam's average score based on the six quizzes is 78%.
What is the average?The average is the mean, a central tendency value.
We compute the mean by summing the values of a data set and dividing by the number of items in the collection.
In this situation, the average of 5 quizzes multiplied by 5 gives the total score in the 5 quizzes, which resulted in the average score.
This total is added to the score in the sixth quiz to get the total score for the six examinations before dividing the sum by 6, giving the overall average.
The average score in 5 quizzes = 74%
Total score in the 5 quizzes = 370% (74 x 5)
The score on the sixth quiz = 99%
Total score in six quizzes = 469% (370 + 99)
The average score in the 6 quizzes = 78.167% (469/6)
= 78%
Thus, Sam scored an average of 78% on the six tests.

Answers
The rate in mm per hour at which the height of the water is changing when the height of the water is 2mm is 55.2
Given data,
A partially filled inverted cone contains water. The inverted cone has a 16 mm radius. The inverted cone is 18 mm in height. if the water's volume is growing at a pace of 548 cubic millimeters per hour.
The rate in mm per hour at which the height of the water is changing when the height of the water is 2 mm;
r/h = 16/18
= 8/9
r = 8h/9
The volume of the cone is;
v = [tex]\frac{1}{3}\pi r^2h[/tex]
v = [tex]\frac{1}{3}\pi (8h/9)^2h[/tex]
v = [tex]\frac{64}{243}\pi h^3[/tex]
Now, differentiating concerning x;
[tex]\frac{dv}{dt}[/tex]= [tex]\frac{d}{dt}[/tex] [tex]\frac{64}{243}\pi h^3[/tex]
[tex]\frac{dv}{dt}[/tex]= 64π/243*[tex]\frac{d}{dt}[/tex] h³
[tex]\frac{dv}{dt}[/tex]= [tex]\frac{64}{81}\pi h^2\frac{dh}{dt}[/tex]
We have;
[tex]\frac{dv}{dt}[/tex]= 548 and h = 2mm
[tex]\frac{dh}{dt} = \frac{548*81}{256\pi }[/tex]

How far an object has fallen if its velocity (v) is 136 ft/s
Solution:
By substituting the value of g & v in the formula we get:
[tex]\rm \implies 136 = \sqrt{2 \times 32 \times h} \\ \\ \rm \implies 136 = \sqrt{64h} \\ \\ \rm \implies 64h = {136}^{2} \\ \\ \rm \implies h = \dfrac{ {136}^{2} }{64} \\ \\ \rm \implies h = \dfrac{18496}{64} \\ \\ \rm \implies h = 289 \: ft[/tex]
