It is given that,
The length of a rectangle is 5 cm more than three times the width.
That is, l=3w+5
Put width, w=12.
Therefore, the length becomes,
l=3(12)+5
l=36+5
l=41 cm.
Hence, the length of the rectangle is 41 cm.
Fowler inc, just paid a dividend of 2.55 per share on its stock. The dividends are expected to grow by 3.9% per year indefinitely. If investers require a 10.4% return on this stock what will the price be in 3 years, what will the price be in 15 years?
When Fowler inc, just paid a dividend, the price in 15 years for the share is $72.36.
How to calculate the price?This will be illustrated as:
P0 = D1 / (Ke - g)
P0 = Current Price
D1 = Expected Dividend after 1 Year
Ke = COst of Equity
g = Growth Rate
Dividend for first year will be:
D1 = D0(1+g)
= $ 2.55 (1+0.039)
= $ 2.55(1.039)
= $ 2.6495
Current price will be:
P0 = D1 / (Ke - g)
= $ 2.6495 / (0.104-0.039)
= $ 2.6495 / 0.065
= $ 40.76
Price in 15 years will be
P15 = D16 / (Ke - g)
P15 = Price after 15 Years
D16 = Expected Div after 16 Years
Ke = COst of Equity
g = Growth Rate
D16 = D0(1+g)^16
= $ 2.55 (1+0.039)^16
= $ 2.55(1.039)^16
= $2.55 * 1.8444
= $ 4.7031
P15 = D16 / (Ke - g)
= $4.7031 / (0.104-0.039)
= $4.7031 / 0.065
= $72.36
The price is $72.36

(a). The daily amount of calories that a rat eats increases steadily from birth to about age 3 months. Then, the amount levels off until about age 6 months, when it increases again.
(b). Jane leaves her house on her bike. She rides at a constant speed until she reaches a lemonade stand, where she parks her bike and takes a rest. Then she turns around and bikes home as fast as she can.
A) The second graph gives the best representation of the daily amount of calories consumed by the rat.
B)The fourth graph gives the best representation of Jane's journey.
The first slope of the graph represents the steady increase in the consumption of calories by the rat until the age of 3. The horizontal line represents the level off until the age of 6. The slopes after the horizontal line represent the increase in consumption of calories after age 6.
The first slope of the graph represents the steady increase in the distance from her home as she is traveling away from her home. The horizontal line that comes after the slope represents the time she rested at the lemonade stand. And the negative slope that comes after the horizontal line represents the decreasing distance to her home as she travels back to her home.

Explanation
Step 1
we have the recursive formula
[tex]f(x)=\begin{cases}f(1)=17 \\ f(n)=f(n-1)-2\text{ if n }>1\end{cases}[/tex]A recursive formula is a formula that defines each term of a sequence using the preceding term(s), we can see in the formula that the new term ( f(n)) equals the previous term minus 2
so
[tex]\begin{gathered} f(1)=17 \\ hence \\ f(n)=f(n-1)-2 \\ \text{for n=2} \\ f(2)=f(2-1)-2 \\ f(2)=f(1)-2 \\ f(2)=17-2=15 \\ so,\text{ the second term is 15} \end{gathered}[/tex]and so on,

[tex]\begin{gathered} f(n)=f(n-1)-2 \\ f(4)=f(4-1)-2 \\ f(4)=f(3)-2 \\ f(4)=13-2=11 \\ \text{hence, the fourth term is 11} \end{gathered}[/tex]so, the answer is

Line c has an equation of y = -5x + 3. Parallel to line c is line d, which passes through the
point (2, -6). What is the equation of line d?
Answer:
Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient so equation of line d is y = -5x + c.
Substitute (2,-6) into the equation to find c.
-6 = -5(2) + c
c = 4
Hence equation of line d is y = -5x + 4.

Slope intercept form:
y = mx + b
m = (y2 - y1)/(x2 - 1) = (-8 - 1)/(2 - (-1)) = -9/(2 + 1) = -9/3 = -3
m = -3
If we take one of the point, for example (2, -8) and use it on the equation with the slope we already found:
y = -3x + b
-8 = -3(2) + b
Solving for b:
-8 = -6 + b
b = -8 + 6 = -2
b = -2
Therefore, the equation is: y = -3x -2

Answer:
(a) 31 years
(b) 59 years
(c) 56 years
Step-by-step explanation:
In general, when reading a stem and leaf plot, we read firstly the number in the steam (middle) and then in the leaf.
Now, let's move on to the question:
(a) As we can see in the graph, the youngest actor has 31 years.
(b) The youngest actress is 21 years old and the oldest is 80.
So, the difference is 80 - 21 = 59 years.
(c) In this exercise, we have to look for actors who had the same age. That means, when evaluating the steam, we will have to find similar values in the leaf. The oldest age shared is 56 years.

In this question, we have been given in a large school, it was found that 80% of students are taking a math class, 75% of student are taking an English class, and 67% of students are taking both.
Let A represents math class, B represents English class
P(A) = 0.80
P(B) = 0.75
P(A ∩ B) = 0.67
We need to find the probability that a randomly selected student is taking a math class or an English class.
P(A U B) = P(A) + P(B) - P(A ∩ B)
P(A U B) = 0.80 + 0.75 - 0.67
P(A U B) = 0.88
Also, we need to find the probability that a randomly selected student is taking neither a math class nor an English class.
P(~(A U B) ) = 1 - P(A U B)
P(~(A U B) ) = 1 - 0.88
P(~(A U B) ) = 0.12
Therefore, the probability that a randomly selected student is taking a math class or an English class is 0.88
And the probability that a randomly selected student is taking neither a math class nor an English class 0.12

Answer
Options A, D and E are correct.
The two functions are increasing.
The function for plan II has a greater unit rate.
The function for plan I has a greater y-intercept.
Explanation
The slope and y-intercept form of the equation of a straight line is given as
y = mx + b
where
y = y-coordinate of a point on the line.
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
b = y-intercept of the line.
For the first plan, there's a one time investment of 15,000 dollars and subsequent monthly payments of 500 dollars.
y = 15,000 + 500x
y = 500x + 15,000
Slope = unit rate of increase = 500
y-intercept = 15,000
For the second plan, the function is just given as
y = 12,000 + 520x
y = 520x + 12,000
Slope = unit rate of increase = 520
y-intercept = 12,000
We can see that
The two functions are increasing.
The function for plan II has a greater unit rate.
The function for plan I has a greater y-intercept.

Report ME accurate to one decimal place because the sample statistics are presented with this accuracy.
M.E. =
Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
The margin error M.E. that corresponds to a sample of size 22 with a mean of 69.3 and a standard deviation of 8.6 at a confidence level of 95% is 0.04694
We would utilize the t distribution in the estimation of the margin of error because the population standard deviation is unknown (and the sample size is less than 30).
Error margin = t-critical * standard deviation/square root sample size
It is given in the above question that,
Standard deviation is given as = 8.6
And, the Sample size which is given is = 22
Also, the confidence level which given is = 95%
Then the alpha will be = 100% - 95%
= 5% = 0.05
Now, the critical value, t would be = alpha / 2
= 0.05 /2 = 0.025
Also, the sample we'll consider will be = given sample size - 1 = 22 -1 = 21
To find the margin error, we'll put all the values in the formula
Error margin = t-critical * standard deviation/square root sample size
= [tex]\frac{0.025 * 8.6}{\sqrt{21} }[/tex]
= 0.215 / 4.58
= 0.04694
Hence, the margin error M.E. that corresponds to a sample of size 22 with a mean of 69.3 and a standard deviation of 8.6 at a confidence level of 95% is 0.04694

The rule of the slope of a line has 2 points is
[tex]m=\frac{y2-y1}{x2-x1}[/tex]A = (1, -2), B = (3, 4), C = (-2, 6)

We will substitute them in the rule above
[tex]\begin{gathered} m=\frac{6-4}{-2-3}=\frac{2}{-5} \\ m=-\frac{2}{5} \end{gathered}[/tex]The slope of BC = -2/5
Since the product of the slopes of the perpendicular line is -1, then if the slope of one is m, then the slope of the other will be -1/m, we reciprocal it and change its sign, then the slope of the altitude of BC should be 5/2
[tex]m_{\perp}=\frac{5}{2}[/tex]The form of the equation in point-slope is
