Mrs. Hamilton Shows Her Students This Graph And Asks Them To Determine How Figure A Was Transformed To

Answers

Answer 1

The best accuracy for the transformation is; Accurate. A reflection over the y-axis and then a translation of 1 up and 2 to the right produces the image, figure B.

What transformation was used on the figure?

In a translation transformation, all the points in the object are moved in a straight line in the same direction. The size, the shape and the orientation of the object remain the same.

In this question, the points on triangle A are: (-1, 0), (-2, 4) and (-1, 4).

Marcus' translation is as follows:

Reflection over the y-axis which is x → -x and the points are: (1,0), (2,4) and (1,4).

2 units to the right which is x → x + 2 and as such the points are: (3, 0), (4,4) and (3,4).

1 unit up which is y → y + 1 and as such, the points are (3,1), (4,5) and (3,5).

The points are the same of triangle B, hence the statement is accurate. According to the order of the translations, the second statement is correct.

how did the temperature change if it decreased by 60% and then increased by 80%

Answers

Answer:

The temperature decreased by 28%

Step-by-step explanation:

How did the temperature change if :

At first it decreased by 60%

Then increased by 80%

Assume that the temperature before decreasing is 100%

∵ The temperature before decreasing = 100%

∵ It decreased by 60%

→  Before decreasing  :  decreasing  :    after decreasing

→  100%                         :  60%              :    100% - 60% = 40%

∴ The temperature after decreasing = 40%

Assume that the temperature after decreasing is 100%

∵ The temperature after decreasing = 100%

∵ It increased by 80%

By using the ratio method

→  After decreasing  :  increasing  :    after increasing

→  100%                      :  80%             :   100% + 80% = 180%

→  40%                        :                       :   x%

By using cross multiplication

∴ 100% × x% = 40% × 180%

- Divide both sides by 100%

∴ x% =

∴ x% = 72%

∵ At first the temperature = 100%

∵ At last the temperature = 72%

∵ The first the temperature > the last the temperature

∴ The decreasing in temperature = 100% - 72% = 28%

Susan's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Susan $5.45 per pound, and type B coffee
costs $4.05 per pound. This month's blend used three times as many pounds of type B coffee as type A, for a total cost of $633.60. How
many pounds of type A coffee were used?

Answers

The amount in pounds of Type A coffee used is 36 pounds.

Using equation to find the number of pounds?

Type A coffee costs Susan $5.45 per pound, and type B coffee

costs $4.05 per pound.

Therefore,

Let x = the number of pounds of Type A coffee.

total pounds = x + 3x

total cost = 5.45(x) + 3x(4.05)

633.60 =  5.45(x) + 3x(4.05)

633.60 =   5.45x + 12.15x

633.60 = 17.6x

divide both sides by 17.6

x = 633.60 / 17.6

x = 36

please help! i will give u 20 points I need the answer with the method

Answers

Answer:

6 mm

Step-by-step explanation:

So, the area he needs to fill isn't really important, you don't need to calculate it. What is necessary is the individual dimensions of that area (width/length). The width and the length must be divisible by the lengths of the tiles. This is so you don't need to cut anything. For example let's say the area needed to be filled was 15 mm (width) by 10 mm (length). If I chose 3mm square tiles, it could perfectly fill up the width, but when it came to the length there would be a small 1 mm gap. And you would need to cut one of the square tiles, so it would have a length of 1 mm. In this case the 15mm was divisible by 3, but the 10 mm wasn't. So using this logic, it can't be the 4 mm square tile since 150mm / 4 mm = 37.5. It can be the 6m since 150mm / 6mm = 25 and 180 mm / 6mm = 30. It can't be the 8 mm since 150 mm / 8mm = 18.75 mm

Second part;

The distance between points A and B is 2•√2 which is different from the distance between the image A' and B' which indicates that the transformation is a non rigid transformation.

The given transformation is presented as follows;

(x, y) → (3•x, 2•y)

Therefore, the images are;

A(3, 5) → A'(3 × 3, 2 × 5) = A'(9, 10)

B(5, 3) → B'(3 × 5, 2 × 3) = B'(15, 6)

Using
[tex]\pi = \frac{22}{7} [/tex]
calculate the value of h

Answers

Answer: 30 cm

Step-by-step explanation:

The volume of the composite solid is 17000 cm³. To find h, we must first subtract the volume of the half cylinder from the composite volume.

From the figure, AE = MK, and so the radius of the half cylinder is 10cm. The volume of the half cylinder is thus [tex]\frac{1}{2}[/tex] the volume of a cylinder. The volume of a cylinder is πr²h. So a half cylinder is 1/2 πr²h. This gives us a volume of  [tex]\frac{1}{2} (\frac{22}{7})(10 cm)^2(28 cm) = 4400 cm^3[/tex].

Thus, the volume of the right prism is 17000cm³ - 4400cm³ = 12600cm³. Consider the cross-section ABKJ. If we multiply this by AE, we'll have the volume of the right prism.

The ABKJ is a trapezoid so it's area is [tex]\frac{1}{2}(AJ + BK) \cdot AB[/tex]. Thus the volume of the right prism is [tex]\frac{1}{2}(AJ + BK) \cdot AB \cdot AE[/tex]. This gives us [tex]\frac{1}{2}(28 + 14) \cdot h \cdot 20 = 12600[/tex], and thus h = 30 cm.

If f is a linear function, f(0.1) = 11.5, and f(0.4) = -5.9, find an equation for the function.

Answers

Considering the expression of a line, the equation for the function that is represented through the points f(0.1) = 11.5, and f(0.4) = -5.9 is y= -58x +17.3.

Linear equation o line

A linear equation o line can be expressed in the form y = mx + b.

where

x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

Knowing two points (x1, y1) and (x2, y2) of a line, the slope m of said line can be calculated using the following expression:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

Equation for the function in this case

In this case, the function f(x) is represented through the points f(0.1) = 11.5, and f(0.4) = -5.9. This is:

(x1, y1)= (0.1, 11.5) (x2, y2)= (0.4, -5.9)

So, the slope m can be calculated as:

[tex]m=\frac{-5.9-11.5}{0.4-0.1}[/tex]

Solving:

m= -58

Considering point 1 and the slope m, you obtain:

11.5= -58×0.1 +b

11.5= -5.8 + b

11.5 + 5.8= b

17.3= b

Finally, the equation for the function that is represented through the points f(0.1) = 11.5, and f(0.4) = -5.9 is y= -58x +17.3.

Number = 78

Next, we evaluate the expressions in the options using a calculator

2 × (10 × 3 + 32) = 124

2 × (13 + 32) = 90

(10 × 3 + 32) =62

2 × (10 × 3 + 3) = 66

None of the options equals 78

Hence, none of the expressions is equivalent to 78

Answer: [tex]y=x+2[/tex]

Step-by-step explanation:

The slope is

[tex]\frac{0-2}{-2-0}=1[/tex]

since the y-intercept is 2, the equation is [tex]y=x+2[/tex]

The point-slope form of the equation of of the line that passes through (-4, -3) and (12, 1) is y - 1 = 1/4(x - 12). What
is the standard form of the equation for this line?
O x- 4y = 8
O x-4y=2
O 4x-y= 8
O 4x-y=2

Answer: [tex]\frac{1}{4}[/tex]x - y = 2

Step-by-step explanation:

    Standard form is Ax + By = C where A, B, and C, are integers.

   Given:

y - 1 = 1/4(x - 12)

  Distribute:

y - 1 = [tex]\frac{1}{4}[/tex]x - 3

  Add 3 to both sides of the equation:

y  + 2 = [tex]\frac{1}{4}[/tex]x

  Subtract y from both sides of the equation:

2 =  [tex]\frac{1}{4}[/tex]x - y

   Apply the reflexive property:

[tex]\frac{1}{4}[/tex]x - y = 2

Identify the 8th term of the given geometric sequence. 1/2, 2, 8, 32,...

Answers

Geometric sequence.

A geometric sequence goes from one term to the next by always multiplying or dividing by the constant value except 0. The constant number multiplied (or divided) at each stage of a geometric sequence is called the common ratio (r).

We have:

[tex]a_1=\dfrac{1}{2}\\\\a_2=2\\\\a_3=8\\\\a_4=32\\\vdots[/tex]

Find the common ratio:

[tex]\boxed{r=\dfrac{a_n}{a_{n-1}}}\Rightarrow r=\dfrac{2}{\frac{1}{2}}=\dfrac{8}{2}=\dfrac{32}{8}=...\\\\\boxed{r=4}[/tex]

The formula of the n-th term of a geometric sequence:

[tex]\boxed{a_n=a_1\cdot r^{n-1}}[/tex]

Substitute:

[tex]a_1=\dfrac{1}{2},\ r=4,\ n=8\\\\a_8=\dfrac{1}{2}\cdot4^{8-1}=\dfrac{1}{2}\cdot4^7=\dfrac{1}{2}\cdot16384\\\\\huge\boxed{a_8=8192}[/tex]

Method step by step:

[tex]a_4=32,\ r=4\\\\a_5=a_4\cdot r\Rightarrow a_5=32\cdot4=128\\\\a_6=a_5\cdot r\Rightarrow a_6=128\cdot4=512\\\\a_7=a_6\cdot r\Rightarrow a_7=512\cdot4=2048\\\\a_8=a_7\cdot r\Rightarrow a_8=2048\cdot4=8192[/tex]
