How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given the direct proportion
y = kx
Now for k = 0
y = 0 so y = 0 is a horizontal line passing through the origin that is the x-axis.
In the graph below I have attached
Black line y = 4x ( k = 4)

The area of the figure is
square units.
Answers
The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
From the figure, the area of triangles can be calculated using the:
Area = (1/2)height×base length
Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)
Area of three triangle = 1/2(24×3) = 36 square units
Area of the figure = area of three triangle + area of the rectangle
= 36 + 6×4
= 60 square units
Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

Why is it wrong to draw y=ln(2x-5) this way?
Answers
well because he did not do it
Notice how
2x-5 = 2x - 2*2.5 = 2(x-2.5)
This means we can replace x with x-2.5 in the second step, in the "wrong way" column.
So,
y = ln(2x)
y = ln( 2(x-2.5) )
y = ln( 2x - 2*2.5 )
y = ln( 2x - 5 )
In the second step, the x-2.5 tells the reader to shift the curve 2.5 units to the right. Therefore, the 1/2 = 0.5 would shift to 0.5+2.5 = 3 as indicated by the correct graph.

Graph that line with slope -1 passing through the point (-2,4)
Answers
Answer:
To graph the line with slope -1 passing through the point (-2,4), we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)where m is the slope of the line, and (x1, y1) is the given point on the line. Substituting the given values, we get:
y - 4 = -1(x - (-2))Simplifying this equation, we get:
y - 4 = -x - 2y = -x + 2Now we can graph this line by plotting the given point (-2,4), and then using the slope of -1 to find one or more additional points on the line. We can do this by starting at the given point and then moving one unit down (since the slope is negative) and one unit to the right (since the slope is -1). This gives us the point (-1,3). We can then connect these two points to graph the line.

Answer:
y = 75
z = 43.3
Step-by-step explanation:
To find the value of y we use the trigonometric identity Sine.
\(sin\ 30 = \frac{y}{150}\\\\y=150*sin30\\y= 75\\\)
Now to find the value of z we can use the trigonometric identity Tangent.
\(tan\ 60=\frac{y}{z}\\\\z=\frac{y}{tan\ 60}\)
We know the value of y is 75 so it becomes,
\(z=\frac{75}{1.732} \\\\z=43.3\)
Answer:
y=-150 ' z = - 468
Step-by-step explanation:
Sin angle = opp/hyp
Cos 30 = y/150
y = 150 ×( cos30)
y= - 150
Tan angles = opp / adj
Tan 60 = - 150 / Z
Z = (-150) / tan 60
Z = (-150) / 0.32
Z= - 468

mega mart sells a large 5kg cake for $2500 while a 2kg chocolate cake cost $1200 what is the cheapest price sam would payfor 10kg of cake for the party
Answers
The cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.
To find the cheapest price Sam would pay for 10kg of cake for the party, we need to compare the prices of the available cakes and determine the most cost-effective option.
At Mega Mart, a 5kg cake costs $2500.
Therefore, the price per kilogram for this cake is:
Price per kilogram at Mega Mart = $2500 / 5kg = $500/kg.
At the same time, a 2kg chocolate cake costs $1200.
So, the price per kilogram for this cake is:
Price per kilogram for the chocolate cake = $1200 / 2kg = $600/kg.
Now, let's calculate the total price for 10kg of cake from each option:
Total price at Mega Mart for 10kg = $500/kg \(\times\) 10kg = $5000.
Total price for 10kg of chocolate cake = $600/kg \(\times\) 10kg = $6000.
Comparing the two options, we see that the Mega Mart cake is the more cost-effective choice.
Sam would pay a total of $5000 for 10kg of cake from Mega Mart, whereas the chocolate cake would cost $6000 for the same quantity.
Therefore, the cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.
In summary, Sam would pay the cheapest price of $5000 to purchase 10kg of cake for the party from Mega Mart.

Triangle not drawn to scale
O A. 1/√2

O D. √2
Answers
The value of cos(45°) is √2/2. The correct answer choice is D. √2.
In the given diagram, the angle labeled as 45° is part of a right triangle. To find the value of cos(45°), we need to determine the ratio of the adjacent side to the hypotenuse.
Since the angle is 45°, we can assume that the triangle is an isosceles right triangle, meaning the two legs are congruent. Let's assume the length of one leg is x. Then, by the Pythagorean theorem, the length of the hypotenuse would be x√2.
Now, using the definition of cosine, which is adjacent/hypotenuse, we can substitute the values:
cos(45°) = x/(x√2) = 1/√2
Simplifying further, we rationalize the denominator:
cos(45°) = 1/√2 * √2/√2 = √2/2
Therefore, the value of cos(45°) is √2/2.
The correct answer choice is D. √2.

The sum of the present value of 1 paid at the end of n periods and 1 paid at the end of 2n periods is 1. Find (1 i) 2n
Answers
Answer:
\((1 + i)^{2n} = \frac{4}{(-1 \± \sqrt{5})^2}\)
Step-by-step explanation:
Using Present Value formula, we have that:
The present value at end of n period is
\(PV_1 = \frac{1}{(1 + i)^n}\)
The present value at end of 2n period is
\(PV_2 = \frac{1}{(1 + i)^{2n}}\)
\(Sum = PV_1 + PV_2\)
And
\(Sum = 1\)
So, we have:
\(PV_1 + PV_2 = 1\)
Substitute values for PV1 and PV2
\(\frac{1}{(1 + i)^n} + \frac{1}{(1 + i)^{2n}}= 1\)
Solving for:
\((1 + i)^{2n\)
\(\frac{1}{(1 + i)^n} + \frac{1}{(1 + i)^{2n}}= 1\)
This can be expressed as
\(\frac{1}{(1 + i)^n} + (\frac{1}{(1 + i)^{n}})^2= 1\)
Let
\(a = \frac{1}{(1 + i)^n}\)
So, we have:
\(a + a^2 = 1\)
Equate to 0
\(a + a^2 - 1= 0\)
\(a^2 + a - 1= 0\)
Using quadratic formula:
\(a = \frac{-B \± \sqrt{B^2 -4AC}}{2A}\)
Where A=1; B =1 and C = -1
\(a = \frac{-1 \± \sqrt{1^2 -4 * 1 * -1}}{2 * 1}\)
\(a = \frac{-1 \± \sqrt{1 +4}}{2 }\)
\(a = \frac{-1 \± \sqrt{5}}{2 }\)
Recall that:
\(a = \frac{1}{(1 + i)^n}\)
So, we have:
\(\frac{1}{(1 + i)^n} = \frac{-1 \± \sqrt{5}}{2 }\)
Invert both sides
\((1 + i)^n = \frac{2}{-1 \± \sqrt{5}}\)
Square both sides
\(((1 + i)^n)^2 = (\frac{2}{-1 \± \sqrt{5}})^2\)
\((1 + i)^{2n} = (\frac{2}{-1 \± \sqrt{5}})^2\)
\((1 + i)^{2n} = \frac{4}{(-1 \± \sqrt{5})^2}\)

a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.
b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.
a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.
In base seven, we have the following conversions:
1 long = 1 unit
1 flat = 10 units
1 block = 10 flats
To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.
So, the fewest number of multibase blocks required would be 2 flats.
Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.
b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.
In base three, we have the following conversions:
1 long = 1 unit
1 flat = 3 units
1 block = 3 flats
To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.
So, the fewest number of multibase blocks required would be 3 flats and 1 unit.

For example, such a temperature increase would take Washburn county's 19 ponds that support brook trout down to 10 ponds. What would be the percent decrease in the number of ponds that support brook trout?
Answers
The percent decrease in the number of ponds that support brook trout would be approximately 47.37%.
To calculate the percent decrease in the number of ponds that support brook trout, we need to determine the difference between the initial number of ponds and the final number of ponds, and then express that difference as a percentage of the initial number of ponds.
Initial number of ponds: 19
Final number of ponds: 10
To calculate the percent decrease, we can use the following formula:
Percent Decrease = (Difference / Initial Value) * 100
Let's apply this formula to the given data:
Difference = Initial number of ponds - Final number of ponds
Difference = 19 - 10
Difference = 9
Percent Decrease = (9 / 19) * 100
Now, let's calculate the percent decrease:
Percent Decrease = (9 / 19) * 100
