Please help me to figure out this math graph problem.
Answer:
Step-by-step explanation:
Here's a graph of a linear function. Write the
equation that describes that function.
xpress it in slope-intercept form.
Answer:
the slope intercept form is y = (1/2)x - 1
Step-by-step explanation:
The slope-intercept form is, y = mx + b
We see from looking at the graph that,
at x = 0, y = -1
So, from this we find that b = -1
at x = 2, y = 0,
now, we find the slope m,
using,
\(m = \frac{y_{2} -y_1}{x_2-x_1}\)
Using x_2 = 2, y_2 = 0,
x_1 = 0, y_1 = -1, we get,
m = (0-(-1))/(2-0)
m = 1/2
So, the slope intercept form is,
y = (1/2)x - 1

show that the set of vectors in is orthogonal and (b)normalize the set to produce an orthonormal set.
An orthonormal set is a set of orthogonal unit vectors.
Normalization is the process of making unit vectors.
Orthonormal VectorsA set of vectors in which each vector is orthogonal to every other vector in the set is called an orthogonal set of vectors.
Two vectors are orthogonal when their dot product equals zero.
An orthonormal set is one in which each vector has length 1 and is orthogonal.
The process of creating a vector of length 1 in the same direction of the original vector is called "normalization".
An orthonormal set of vectors that is a basis of a vector space is quite useful. We can use the Gram-Schmidt process to transform a basis of a vector space (which may not be orthogonal) into an orthonormal basis.
To normalize vectors to produce an orthonormal set of vectors, we calculate the length of the vector and divide the vector by its length, to obtain a unit vector.
Since the question asked about "how to normalize vectors to produce an orthonormal set" that implies that the vectors already form an orthogonal set.

Determine if the equation given in slope-intercept form represents the graph. If the equation is correct support your reasoning with why it is correct. If the equation is incorrect, give the correct slope-intercept form equation explaining how you determined it.
The equation of the line would be y = (4/5)x + 4 which in slope-intercept form represents the graph.
The graph is given in the question.
As per the given line, we take two points (0, 4) and (5, 8)
Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
x₁ = 0, y₁ = 4
x₂ = 5, y₂ = 8
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Substitute values in the equation, we get
⇒ y - 4 = (8 - 4)/(5-0 )[x -0]
⇒ y - 4 = (4/5)x
⇒ y = (4/5)x + 4
The given equation of the line y = 4x + 5 is incorrect because its slope is not correct.
So, the equation of the line would be y = (4/5)x + 4.

The sum of the perimeters of an equilateral triangle and a square is 22. Find the dimensions of the triangle and the square that produce a minimum total area. dimension of triangle dimension of squar
Answer:
The dimension of the triangle is 4.144 m and the dimension of the square is 2.392 m
Step-by-step explanation:
let a side of the equilateral triangle = x
let a side of square = y
3x + 4y = 22
4y = 22 - 3x
\(y = \frac{11}{2} -\frac{3x}{4}\)
subjective function, the total area is given by;
\(f(x,y) = \frac{x^2\sqrt{3} }{4} +y^2\)
\(f(x) = \frac{x^2\sqrt{3} }{4} + (\frac{11}{2} -\frac{3x}{4})^2\\\\f(x) = \frac{x^2\sqrt{3} }{4} +\frac{121}{4} -\frac{33x}{4} +\frac{9x^2}{16} \\\\f(x)' = \frac{x\sqrt{3} }{2} -\frac{33}{4} +\frac{9x}{8} \\\\\frac{x\sqrt{3} }{2} -\frac{33}{4} +\frac{9x}{8}=0\\\\\frac{x\sqrt{3} }{2} + \frac{9x}{8} =\frac{33}{4}\\\\\frac{4x\sqrt{3} +9x}{8} = \frac{33}{4}\\\\4x\sqrt{3} +9x = 66\\\\x(4\sqrt{3} +9) = 66\\\\x(15.928) = 66\\\\x = \frac{66}{15.928}\\\\x = 4.144 \ m\)
solve for y
\(y = \frac{11}{2} -\frac{3x}{4}\\\\y = \frac{11}{2} -\frac{3*4.144}{4}\\\\y = 5.5-3.108\\\\y = 2.392 \ m\)
Therefore, the dimension of the triangle is 4.144 m and the dimension of the square is 2.392 m

Gabe wants to buy a dog collar. The sale price is $3.91. What was the original price?
$
the original price was really "x", which oddly enough is the 100%, but today the collar is on sale at 15% off, that means the sale price is 100% - 15% = 85% of the original price, and we happen to know that's $3.91, so
\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} x & 100\\ 3.91& 85 \end{array} \implies \cfrac{x}{3.91}~~=~~\cfrac{100}{85} \\\\\\ \cfrac{x}{3.91} ~~=~~ \cfrac{20}{17}\implies 17x=78.2\implies x=\cfrac{78.2}{17}\implies x=4.6\)

1. The new volume will be 60 cubic feet. 2. Molly will earn $31.25 if she sells all of the dog beds after subtracting the cost of the fabric.
Describe Volume?In general, volume refers to the amount of space occupied by an object or substance, measured in three dimensions: length, width, and height. It is a physical quantity that is typically expressed in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³).
1. The volume of the cuboid is calculated as follows:
Volume = length x width x height
Volume = 5 ft x 3 ft x 2 ft
Volume = 30 cubic feet
If we double the height, the new height will be 2 x 2 ft = 4 ft. The new volume can be calculated as:
New Volume = length x width x new height
New Volume = 5 ft x 3 ft x 4 ft
New Volume = 60 cubic feet
Therefore, the new volume will be 60 cubic feet.
2. Step 1: Determine how many dog beds Molly can make with the fabric she bought.
Molly bought 12.5 yards of fabric, and she uses 2.5 yards of fabric for each dog bed. We can use division to find how many dog beds she can make:
12.5 yards / 2.5 yards per dog bed = 5 dog beds
Therefore, Molly can make 5 dog beds with the fabric she bought.
Step 2: Calculate the cost of the fabric for each dog bed.
Molly bought the fabric for $4.50 per yard, and she uses 2.5 yards of fabric for each dog bed. Therefore, the cost of the fabric for each dog bed is:
$4.50 per yard x 2.5 yards per dog bed = $11.25 per dog bed
Step 3: Calculate the revenue from selling one dog bed.
Molly sells each dog bed for $17.50.
Step 4: Calculate the profit from selling one dog bed.
Profit = revenue - cost
Profit = $17.50 - $11.25
Profit = $6.25
Step 5: Calculate the total revenue from selling all of the dog beds.
Molly can make 5 dog beds, and each dog bed sells for $17.50. Therefore, the total revenue is:
5 dog beds x $17.50 per dog bed = $87.50
Step 6: Calculate the total cost of the fabric for all of the dog beds.
Molly uses 2.5 yards of fabric for each dog bed, and she can make 5 dog beds. Therefore, the total cost of the fabric is:
2.5 yards per dog bed x 5 dog beds = 12.5 yards
$4.50 per yard x 12.5 yards = $56.25
Step 7: Calculate the total profit from selling all of the dog beds.
Profit = revenue - cost
Profit = $87.50 - $56.25
Profit = $31.25
Therefore, Molly will earn $31.25 if she sells all of the dog beds after subtracting the cost of the fabric.

What is the slope of the line on the graph?
Enter your answer in the box.
Answer:
-2/6
Step-by-step explanation:
Slope is the m in y = mx + b, while b is y-intercept.
Just by looking at it, you can see that the line has a negative slope becasue it's going downwards and to the right. You can also tell that the slope is in fact -2/6 because it goes downwards⬇ 2 units and to the right ➡ 6 units.
Remember rise/run, where rise is looking at the y-axis or vertical and run is the x-axis or horizontal.

point C (4, -3) is translated left 3 and up 5 and is then dilated by a scale factor of 4. What are the coordinates of C'?
Answer: (4, 8)
Step-by-step explanation:
When you translate something to the left you need to subtract the amount you moved left from the original x input
1. Subtract 3 from the coordinates x input
4 - 3 = 1
When you translate something up you need to add the amount you moved up to the original y output
2. Add 5 to the coordinates y output
-3 + 5 = 2
When done translating to the left and up your coordinate is now (1, 2)
When dialating something you need to multiply the scale factor in which you dialated the coordinate to both the x input and y output
3. Multiply 4 to the x input and y output of your newley translated coordinate
1 × 4 = 4 (x input)
2 × 4 = 8 (y output)
So now your final coordinate for C' is (4, 8)!

Answer:
Given equations:
Unpaid balance = previous balance - (payments & credits)Finance charge = unpaid balance x periodic rateNew balance = unpaid balance + finance charge + new purchasesConvert the periodic rate from percent into decimal by dividing the percent value by 100.
Simply use the values from the tables to calculate the unpaid balance, finance charge and new balance using the given equations (you need to calculate the unpaid balance to be able to calculate the figures needed to complete the tables)
1. Periodic rate = 1.58% = 1.58/100 = 0.0158
⇒ Unpaid balance = 194.06 - 61.50 = 132.56
⇒ Finance charge = 132.56 x 0.0158 = 2.09
⇒ New balance = 132.56 + 2.09 + 29.80 = 164.45
2. Periodic rate = 2.08% = 2.08/100 = 0.0208
⇒ Unpaid balance = 981.35 - 750 = 231.35
⇒ Finance charge = 231.35 x 0.0208 = 4.81
⇒ New balance = 231.35 + 4.81 + 416.49 = 62.65
3. Periodic rate = 2.0% = 2.0/100 = 0.02
⇒ previous balance = 291.84
⇒ payments & credits = 200.00
⇒ new purchases = 17.40 + 17.70 + 46.04 = 81.14
⇒ Unpaid balance = 291.84 - 200 = 91.84
⇒ Finance charge = 91.84 x 0.02 = 1.84
⇒ New balance = 91.84 + 1.84 + 81.14 = 174.82
4. Periodic rate = 1.875% = 1.875/100 = 0.01875
Finance charge = unpaid balance x periodic rate
⇒ 7.99 = unpaid balance x 0.01875
⇒ unpaid balance = 7.99 / 0.01875 = 426.13
payments & credits = 300.00
⇒ Unpaid balance = previous balance - (payments & credits)
⇒ 426.13 = previous balance - 300
⇒ previous balance = 426.13 + 300 = 726.13
new purchases (charges) = 238.75
⇒ New balance = unpaid balance + finance charge + new purchases
⇒ New balance = 426.13 + 7.99 + 238.75 = 672.87
