how to plot and graph y1 = 17,105 + 1.31x
The attached graph represents the graph of the equation y1 = 17,105 + 1.31x
How to plot and graph the equation?The equation is given as:
y1 = 17,105 + 1.31x
To plot and graph the equation, we set some values for x and calculate the corresponding y values.
Let x = 0, 1, 2 and 3.
So, we have:
y1 = 17,105 + 1.31 * 0 = 17105
y1 = 17,105 + 1.31 * 1 = 17106.31
y1 = 17,105 + 1.31 * 2 = 17107.62
y1 = 17,105 + 1.31 * 3 = 17108.93
The graph can then be plotted using the above points

First thing we need to keep in mind is the fact that this graph is indeed a circle. We know this because we are adding two cubic roots to each other which makes the graph a circle. We know the two separate functions are cubic roots because they each have an exponent of two. Not only is this function whose graph is a circle, but the midpoint of this circle is (2,2).

On a coordinate plane, a straight red line with a negative slope, labeled g of x, A graph shows the number of texts, numbered 10 to 100, on the x-axis, and the total cost in dollars, numbered 3 to 27, on the y-axis. A straight red line with a positive slope, labeled Emilia, begins at (0, 10), and a straight blue line with a positive slope, labeled Hiroto, begins at (0, 20). Both lines intersect at point (50, 22.5).
Hiroto’s texting plan costs $20 per month, plus $0.05 per text message that is sent or received. Emilia’s plan costs $10 per month and $0.25 per text. Using the graph below, which statement is true?
Hiroto’s plan costs more than Emilia’s plan when more than 50 texts are sent.
Both plans cost the same when 22 texts are sent.
Emilia’s plan costs more than Hiroto’s plan when more than 22 texts are sent.
Both plans cost the same when 50 texts are sent.
Answer: Both plans cost the same when 50 texts are sent.
Step-by-step explanation:
When x=50 (meaning 50 texts are sent), the y coordinate (which represents the cost) is the same.

Answer:
The bottom one ....see below
Step-by-step explanation:
Using reference angle of pi/8 and half angle trig identity:
cos ( angle/2) = -sqrt (1 + cos (angle) /2)
cos ( pi/4 / 2) = - sqrt (1+ cos ( pi/4)/2)
cos (pi/8) = - sqrt (1 + sqrt (2) / 2)

The gates of an amusement park are closely monitored to determine whether the number of people in the amusement park ever poses a safety hazard. On a certain day, the rate at which people enter amusement park is modeled by the function e(x)=0.03x^3+2, where the rate is measured in hundreds of people per hour since the gates opened. The rate at which people leave the amusement park is modeled by the function l(x)=0.5x+1, where the rate is measured in hundreds of people per hour since the gates opened. What does (e−l)(4) mean in this situation?
The meaning of (e−l)(4) in this situation is that there are 92 people in the amusement park 4 hours after the gates open.
How to explain the value?e(x) = 0.03x³ + 2
l (x) = 0.5x + 1
Therefore, ( e - l) = [ .03x^3 + 2 ] - [ .5x + 1 ] will be:
= 0.03x³ - 0.5x + 1
Therefore, (e - l ) (4) = 0.03(4)³ - 0.5(4) + 1 = 92
Therefore, it means that 4 hours after the park opens, the rate that the number of people is changing is 92 people per hour

A rancher raises 5 times as many cows as horses. If he has 132 animals
let x = horses
5x = cows
x + 5x = 132
6x = 132
Divide both sides by 6
X = 22
he has 22 horses and 110 cows
There are 22 horses and 110 cows.
What is an equation?"It is a mathematical statement which consists of equal symbol between two mathematical expressions."
For given question,
Let 'c' represents the number of cows and 'h' represents the number of horses.
A rancher raises 5 times as many cows as horses.
So, we get an equation,
⇒ c = 5 × h .................(i)
There are 132 animals.
So, we get an equation,
⇒ c + h = 132 ..................(ii)
Substitute the value of c = 5h in equation (ii)
⇒ c + h = 132
⇒ 5h + h = 132
⇒ 6h = 132
⇒ h = 22
This means, there are 22 horses.
Substitute the vale of h in equation (i),
⇒ c = 5 × h
⇒ c = 5 × 22
⇒ c = 110
This means, there are 110 cows.
Therefore, there are 22 horses and 110 cows.

The risk-free rate is 4 percent, the market return is 15 percent, and the tax rate is 20 percent. What is WACC?
The value of WACC is 6.72%
what is WACC?WACC is calculated by multiplying the cost of each capital source (debt and equity) by its relevant weight by market value, and then adding the products together to determine the total.
WACC=[(Market value of Equity*cost of equity+ Market value of Debt* post tax cost of debt)/(Market value of Equity+ Market value of Debt)]
Market value of Equity= 40,000*$85=$3,400,000
Cost of equity=Risk free return+ Beta equity*market retrun
=4 +0.67*15
