The correct statement will be:
A. The rate of change is the number of inches grown per month, and the initial value is the starting height.
We can form the following equation from the given data:
H(m) = 13 + 41m,
Where H ( Height ) is a function of the number of months ( m ).
We can see that the height changes with respect to months i.e. as the number of months increases, the height of the sunflower also increases.
The initial value or the initial height of the sunflower remains constant throughout and has less impact on its height.
So, option A will be the ultimate explanation for the data given.

Answer:
Step-by-step explanation:
This is a linear function of time, as mentioned.
A linear function is always in the form of:
[tex]y=mx+b[/tex]
The 'sunflower's height is a linear function of time', so the [tex]x[/tex] variable represents the time (which is in terms of months here), and the [tex]y[/tex] would represent the sunflower's height after time has passed.
The initial value is when [tex]x=0[/tex].
[tex]x=0[/tex] means at the very beginning.
At the very beginning, the height would be the starting height, so the initial value would be the starting height.
The rate of change means the change in [tex]y[/tex] in respect to [tex]x[/tex].
Since [tex]y[/tex] represents the height after [tex]x[/tex] months, the rate of change would be the change in height per month.
You could also write it as the number of inches grown per month.
The initial value is the starting height, and the rate of change is the number of inches grown per month, so the correct answer is (A).

Two cities A and B are shown on diagram. every 1 cm = 4 km.
1) Find scale
2) Find distance between A and B
3) "C" city is in west 12km from A, 20km from B. Locate "C" on diagram.
Answers
1. The scale is of 1:400,000.
2. The distance between A and B is of 36 km.
3. The diagram with city C is given at the end of the answer.
What is a scale?The scale of a drawing is how much each unit in the drawing represents in actual distance.
In the context of this problem, the scale is given as follows:
1 cm = 4 km
Meaning that each cm drawn represents 4 km of actual distance.
Using the same unit, we have that:
4 km = 4 x 100,000 cm = 400,000 cm.
Hence the scale is given by:
1:400,000.
Measuring on the drawing, the distance between A and B is of 9 cm, hence, applying the scale, the real distance is of:
9 x 4 km = 36 km.
In the diagram, considering the given scale, we want to position city C 3 cm from City A, to the west = to the left.

a. $120
b. $500
c. $600
d. $700
Answers
B. 500 is the answer
The approximate net pay of Juanita is $500. Therefore, option B is the correct answer.
Given that, Juanita has a part-time job that pays $12/hour and works about 50 hours every month.
What is the net pay?Net pay means take-home pay or the amount employees earn after all payroll deductions are subtracted from their gross pay.
Now, total money earned in a month
= 12 × 50 = 600
Now
6.2% of 600 = $37.2
= 600 - 37.2 = $562.8
1.45% of 562.8 = $8.1606
= 562.8 - 8.1606 = $554.6394
10% of 554.6394 = $55.46394
= 554.6394 - 55.46394 = $499.17546
Total deductions = $499.17546
So, net pay = grass pay - deductions
= 600 - 105.9
= $499.17546
The approximate net pay of Juanita is $500. Therefore, option B is the correct answer.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. For example, 3x + 5 = 15.
Given,
Jonah is at a depth of -20ft.
Makayla is at a depth of -12.5ft.
at the rate of descending is 0.5.
Given equation is
2(-20+0.25s) = -12.5-0.5s
-40 + 0.5 s = -12.5 -0.5s
0.5s + 0.5s = -12.5+40
1s = 28.5

The probability that a randomly selected car gets more than 40 mpg is equal to 0.771.
Let us assume that the miles-per-gallon rating of passenger cars be represented by random variable X. According to the question we know that X ≈ N (μ = 33.8 mpg and σ² = 3.5² mpg). Now, to compute the probability that a randomly selected passenger will gets less than 40 mpg will be given as
P(X < 40) = P(X - μ/σ > 40 - 33.8/3.5)
= P(Z < 1)

Answers
The 90% confidence interval for the class is [73.49, 76.51].
Confidence interval is defined as the range of values where a parameter might fall at a given confidence level. It can be calculated using the formula below.
CI = μ ± z x SD/√n
where CI = confidence interval
μ = sample mean = 75
z = found by using a z-score table
SD = sample standard deviation = 5
n = sample size = 30
At 90% confidence level, the area in each tail of the standard normal curve is 5, and the cumulative area up to the second tail is 95.
(100 - 90) / 2 = 5
100 - 5 = 95
Find 0.95 in the z-table to get the value of z.
At p = 0.95, z = 1.65
Plug in the values to the formula for confidence interval, CI.
CI = μ ± z x SD/√n
CI = 75 ± 1.65 x 5/√30
CI = 75 ± 1.51
CI = [73.49, 76.51]
Hence, for every 100 samples, at 90% confidence level, the mean will be between 73.49 and 76.51.

Answers
The lower cost will occur at the extreme point, that is if the number of videos rented daily is 8 pieces and the cost will be $550.
The cost function is given by:
C(x) = 2x² - 32x + 678
The lowest cost happens at the extreme point. In this point the derivative of C(x) is equal to zero.
Take the derivative:
C'(x) = 4x - 32 = 0
4x = 32
x = 32/4 = 8
Hence, the lowest cost will occur if the number of video rented daily is 8 pcs.
Substitute x = 8 into the cost function:
C(8) = 2(8)² - 32.(8) + 678 = 550

given y is inversely proportional to x³ then the equation relating them is
y = [tex]\frac{k}{x^3}[/tex] ← k is the constant of proportion
to find k use any of the ordered pairs from the table
using (1, 8 ) , then
8 = [tex]\frac{k}{1^3}[/tex] = [tex]\frac{k}{1}[/tex] ⇒ k = 8
y = [tex]\frac{8}{x^3}[/tex] ← equation of proportion

when y = 64 , then
64 = [tex]\frac{8}{x^3}[/tex] ( multiply both sides by x³ )
64x³ = 8 ( divide both sides by 64 )
x³ = [tex]\frac{8}{64}[/tex] = [tex]\frac{1}{8}[/tex] ( take cube root of both sides )

Using the segment addition postulate, the lengths of the sides are given as follows:
AM: 4.5625.AR: -0.8125.Segment Addition PostulateThe segment addition postulate is a geometry axiom that states that a line segment, divided into a number of smaller segments, has the length given by the sum of the lengths of the smaller segments.
In this problem, the line AM is divided into two segments by point R, as follows:
AR = 9x + 2.RM = 2x + 6.The total length of the line is given by:
AM = -5x + 3.
Hence the solution for x is given as follows:
AR + RM = AM
9x + 2 + 2x + 6 = -5x + 3
11x + 8 = -5x + 3
16x = -5.
x = -5/16
x = -0.3125.
Hence the lengths are:
AM = 5x - 3 = -5(-0.3125) + 3 = 4.5625.AR = 9x - 2 = 9(-0.3125) + 2 = -0.8125.There is a typo in the signals as we have a negative length, which is not possible, but the procedure is as shown in this problem.
