True, 0.5 is the coefficient of v² in the expression v + 0.5v².
What is a Coefficient?A coefficient is a number or quantity related to a variable. It is usually an integer multiplied by the variable and displayed next to it. Variables that do not have a numerical value are assumed to have a coefficient of one. A coefficient might be positive or negative, real or imaginary, and expressed in decimals or fractions.Given expression is v + 0.5v².
Follow the methods below to find the coefficient of a variable in a term:
Step 1: Encircle the variable and its power whose coefficient we're looking for.
So here we are looking for the coefficient of v²
Step 2: Forget about that variable and think about all the other numbers or variables that were written with it. That is the coefficient.
Hence, the required coefficient is 0.5.

Use 3.14 for Te.3 in4 inA = 37.12 square inches, Pz 16.28 inchesA = 18.28 square inches, P 22.56 inchesA = 37.12 square inches, P = 22.56 inchesA ~ 18.28 square inches, P 16.28 inches
Answers
Solution
For this case we can find the area as the sum of the rectangle and the semicircle so we have this:
A1= 3in * 4in= 12 in^2
A2 = (pi/2) *(2in)^2 = 6.28 in^2
then the total area is:
A= A1+ A2= 12+ 6.28 in^2 = 18.28 in^2
And then the perimeter similarly we have:
P= 2*4 in + 2*3in + 2pi*(4in/2) = 8+ 6+ 12.56 in= 26.56in
Then the final answer is:
Area ~18.28 in^2 and Perimeter ~26.56 in

At noon, ship A is 50 nautical miles due west of ship B. Ship A is sailing west at 17 knots and ship B is sailing north at 17 knots. How fast (in knots) is the distance between the ships changing at 5 PM? (Note: 1 knot is a speed of 1 nautical mile per hour.)
______ knots
Answers
The distance is changing at 153 nots at 5 P.M.
According to the Pythagoras Theorem, the square of the hypotenuse of a right angle triangle is equal to the sum of squares of the other two sides of the triangle. A derivative is suppose x and y are two variables, then the rate of change of x with respect to y is called a derivative. Differentiation is a process of finding the derivative of a function.
According to the question,
At noon, ship A is 50 nautical miles due west of ship B. (given)
Ship A is sailing west at 17 knots (given)
ship B is sailing north at 17 knots (given)
using the Pythagorean Theorem,
c^2 = a^2+b^2
Here, c is the distance between them at any point
a is the distance of ship A from initial point
b is the distance of ship B from initial point
Now,
initially ship A is due by 50 nautical miles (given)
and in 5 hours it travels 35*17 miles (given)
So, a = 50+5*17 = 50+85 = 135 nautical miles
Similarly b = 5*17 = 85 nautical miles
c^2 = 135^2+85^2 = 18225+7225
= 25450
c = √25450
c = 159.53 nautical miles
But we need to find how fast (in knots) is the distance between the ships changing
that is we need dC/dt (differentiation)
c^2 = a^2+b^2
Differentiating we get,
2cdc/dt = 2a*da/dt + 2b* db/dt
(the power comes on front during differentiating)
We now have da/dt = 17
db/dt = 17
So, dc/dt = (135*17+85*17)/(159.53) = 153 approx. knots
Therefore, we can conclude that the distance is changing at 153 nots at 5 P.M.

- The equation for the potential given is:
[tex]V(t)=320e^{-3.1t}[/tex]Question 1:
- To find when the potential is 150V, we simply substitute the value of V = 150 into the equation and then find the corresponding value of t.
- Thus, we have:
[tex]\begin{gathered} V=150 \\ \\ 150=320e^{-3.1t} \\ \\ \text{ Divide both sides by 320} \\ \\ e^{-3.1t}=\frac{150}{320}=\frac{15}{32} \\ \\ \text{ Take the natural log of both sides} \\ \\ \ln e^{-3.1t}=\ln(\frac{15}{32}) \\ \\ -3.1t=\ln(\frac{15}{32}) \\ \\ \text{ Divide both sides by -3.1} \\ \\ t=-\frac{1}{3.1}\ln(\frac{15}{32}) \\ \\ t=0.2444s\text{ \lparen To 4 decimal places\rparen} \end{gathered}[/tex]Question 2:
- The rate at which the changing occurs is gotten by differentiating the function with respects to time.
- That is,
[tex]\begin{gathered} V(t)=320e^{-3.1t} \\ \\ V^{\prime}(t)=\frac{d}{dt}(320e^{-3.1t}) \\ \\ V^{\prime}(t)=320(-3.1e^{-3.1t}) \\ \\ V^{\prime}(t)=-992e^{-3.1t} \end{gathered}[/tex]- Now that we have the expression for the rate of change of potential with time, we can proceed to find how fast the changing of potential V is happening at t = 0.2444s.
- Thus, we have:
[tex]\begin{gathered} V^{\prime}(t)=-992e^{-3.1t} \\ put\text{ }t=0.2444 \\ \\ V^{\prime}(t)=-992e^{-3.1\times0.2444} \\ \\ \therefore V^{\prime}(t)=-465.02125...\approx-465.0\text{ v/s} \end{gathered}[/tex]Question 3:
- The voltage is changing at -50v/s when we substitute V'(t) = -50 into the equation for V'(t).
- We have that:
[tex]\begin{gathered} V^{\prime}(t)=-992e^{-3.1t} \\ \\ V^{\prime}(t)=-50 \\ \\ -50=-992e^{-3.1t} \\ \\ \text{ Divide both sides by -992} \\ \\ e^{-3.1t}=\frac{-50}{-992}=\frac{25}{496} \\ \\ \text{ Take the natural log of both sides} \\ \ln e^{-3.1t}=\ln(\frac{25}{496}) \\ \\ -3.1t=\ln(\frac{25}{496}) \\ \\ \text{ Divide both sides by -3.1} \\ \\ \therefore t=-\frac{1}{3.1}\ln(\frac{25}{496}) \\ \\ t=0.96377...\approx0.9638seconds\text{ \lparen To 4 decimal places\rparen} \end{gathered}[/tex]Final Answers

Please help me with these graphs i am not sure which one should be correct in order to explain this to my son. I have attached the pictures of the graph What graph represents the system of linear inequalities?2x+y<1y≥1/2x+2
Answers
The given inequalities are
2x + y < 1
y ≥ x/2 + 2
The first step is to write both inequalities as equations. We have
2x + y = 1
y = x/2 + 2
The next step is to plot the straight line graphs for each equation. Since we are given options, we would find the x and y intercepts of each equation and select the graph that matches them.
Recall, x intercept is the value of x when y is zero
y intercept is the value of y when x is zero
For the first equation,
when x = 0, we have
2(0) + y = 1
0 + y = 1
y = 0. This means that y intercept = 0
when y = 0,
2x + 0 = 1
2x = 1
x = 1/2 = 0.5
This means that x intercept = 0.5
The line representing this equation should pass through the y axis at y = 0 and the x axis at x = 0.5
Also, the line would be dashed(not solid) because the solutions to the inequality do not include the values on the line.
For the second equation,
when x = 0, y = 0/2 + 2 = 0 + 2 = 2
when y = 0, we have
0 = x/2 + 2
x/2 = 0 - 2 = - 2
x = - 2 * 2 = - 4
The line representing this equation should pass through the y axis at y = 2 and the x axis at x = - 4
Also, the line would be a solid line because the solutions to the inequality include the values on the line.
The next step is to determine the shaded region for each inequality. Where the shaded regions overlap is the solution. The shaded regions in each option indicate the solution. We would pick points which we would test in each of the shaded regions
For the first option, let us pick a point in the shaded region. Let us pick x = - 2 and y = 2
We would plug these values in both inequalities and see if they satisfy it.
For the first,
2x + y < 1
y < 1 - 2x
Plugging in x = - 2 and y = 2, we have
2< 1 - 2(-2)
2 < 1 + 4
2 < 5
This is true
For the second,
y≥ x/2 + 2
Plugging in x = - 2 and y = 2, we have
2 ≥ -2/2 + 2
2 ≥ - 1 + 2
2 ≥ 1
This is also true
Thus, the first option is correct

[tex]\begin{gathered} \text{ markup amount = cost price }\cdot\text{ markup percentage} \\ \text{ replacing} \\ \text{markup amount }=10\cdot1.15=11.5 \end{gathered}[/tex]Therefore, the total price would be:
[tex]t=10+11.5=21.5[/tex]Now we apply sales tax for the price and calculate the price after tax, like this:
[tex]\begin{gathered} t=21.5+21.5\cdot\frac{5.5}{100} \\ t=21.5+1.1825 \\ t=22.6825\cong22.68 \end{gathered}[/tex]$22.68 is the total cost of the bracelet
Gianna went shopping for a new camera because of a sale. The price on the tag was $26, but Gianna paid $13 before tax. Find the percent discount.
Answers
The percent discount of the camera is 50%.
What is percentage discount?Percentage discount is a discount that is given to a product or service that is given as an amount per hundred.
In other words, the percent discount is list price minus the sale price then divided by the list price and multiplied by 100 to get a percentage.
Hence,
she bought the camera for $13 but the price tag is $26.
Therefore,
percentage discount = tagged price - sale price / tagged price × 100
tagged price = 26 dollars
sale price = 13 dollars
percentage discount = 26 - 13 / 26 × 100
percentage discount = 13 / 26 × 100
percentage discount = 1 / 2 × 100

percentage discount = 50%

The total kg of rice bought is 75kg
Each week, 4.5kg is used,
Let the number of weeks be represented by n

The relationship between the values above can be given as,
[tex]r=75-4.5n[/tex]For 6 weeks, the kilogram of rice left where n = 6 is,
[tex]\begin{gathered} r=75-4.5n \\ r=75-4.5(6)=75-27=48\operatorname{kg} \end{gathered}[/tex]For 12 weeks, the kilogram of rice left where n = 12 is,
