a) The orientation of the figure ABCDE is clockwise. The orientation of figure A'B'C'D'E' is counterclockwise, so at least one reflection is involved. The direction of AB is North, while the direction of A'B' is West, so a rotation of 90° is involved. Both of these can be accomplished by a reflection across the line that has a direction halfway between these, Northwest. The x-coordinate of point D is the same as that of D', so it is convenient to put point D on the line of reflection.

A transformation sequence that maps ABCDE to A'B'C'D'E' is ...

The attachment shows the result of reflecting the figure across the line.

b) About any reflection will give the figure the proper orientation. Depending on what it is, some amount of rotation and/or translation may be required.

We can reflect point D across the line y=-2 to put it where point D' is. That reflection changes the direction of AB to South, so we need to rotate the figure 90° CW to get AB to point West. Since we want point D' to be invariant, we can use that point as the center of rotation.

A second transformation that gives the same mapping is ...

If rain is falling at a rate of 2.56 inches per hour, one would expect 9.6 inches of rainfall after 3.75 hours.

The question pertains to the calculation of total rainfall when the rate of rainfall and time of rainfall are known.

I think that this is the x-intercept method:

First of all, we set y=x^3-6x^2+11x-6.

To find x, we need to let y=0. (y is also equals to f(x))

f(x)=x^3-6x^2+11x-6

In order to make f(x)=0, what does x have to be?

f(1)=0

So then we divide x^3-6x^2+11x-6 by x-1. Why? Because that will not give us a remainder.

(x^3-6x^2+11x-6)/(x-1) = x^2-5x+6

Now, we need to factorize it.

x^2-5x+6 = (x-2)(x-3)

So x=2,3

Answer:

y = 2.5(x + 2)^2 - 3

The answer is A

Step-by-step explanation:

The general equation for the vertex is

y  =  a (x + b)^2 + c

a we are not certain about

b = 2

c = - 3

y = a(x + 2)^2 - 3 Now we have to solve for a.

a is found by using the one point we know (0,7) It means when x = 0 y = 7 so just put those two numbers in.

7 = a(0 - 2)^2 - 3

7 = a (- 2)^2 - 3       Add 3 to both sides.

7 + 3 = a(4)              Combine 7 and 3

10 = 4a                     Divide by 4

10/4 = a                    Do the actual division    

2.5 = a

Answer: See above

A

the equation of a parabola in vertex form is

y = a(x - h )² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here the vertex = (- 2, - 3 ), thus

y = a(x + 2 )² - 3

to find a substitute (0, 7 ) into the equation

7 = 4a - 3 ( add 3 to both sides )

10 = 4a ( divide both sides by 4 )

a = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]

y = [tex]\frac{5}{2}[/tex](x + 2 )² - 3

Let the width of rectangle be X inches

Then according to question

Length of rectangle will be 3X

Also, we know that

Area of rectangle is = L×B

108 = X . 3X

3X^2 = 108

Divide both sides by 3

X^2 = 36

Taking squareroot of both sides

X=6

Therefore, width of rectangle is 6 inches

Answer:

1. 6 in.

Step by step explanation:

Let the width of our rectangle be x inches.

We have been given that the length of our rectangle is three times the width, therefore, length of our triangle will be 3x inches.

We are told that area of the rectangle is 108 square inches.

Since we know that [tex]\text{Area of a rectangle}=\text{Width}\cdot\text{Length}[/tex]

Let us substitute our given information in area formula.

[tex]108=x\cdot 3x[/tex]

Upon multiplying 3x by x we will get,

[tex]108=3x^{2}[/tex]

Let us divide both side of our equation by 3.

[tex]\frac{108}{3} =\frac{3x^{2}} {3}[/tex]

[tex]36=x^{2}[/tex]

Upon taking square root of both sides of our equation we will get,

[tex]6\pm=x[/tex]

Since width cannot be negative, therefore, width of our rectangle will be 6 inches and 1st option is the correct choice.

Answer:

1721 $

1612.80

Step-by-step explanation:

Straight line depreciation means depreciation is the same spread over for all the years.  The spread over amount is nothing but total cost of equipment - salvage value.

Here we have

Cost of equipment(Purchase cost)   ...    18000

Shipping costs                                   ...        620

Installation costs                                ...        590

Total cost of equipment                    ...     19210

Less: salvage value at the end         ...        2000

Net cost of equipment for 10 years ...      17210

Depreciation per year = Net cost /number of years of life

= 17210/10 = 1721/-

Hence answer is 1721/- for all years and also hence for year 2.

Answer:

Given is that Lance rotates the figure 180° and Celina rotates the figure 90°

Now, when the figure is rotated 180 degrees, it will be turned around the origin in a way that the new place of the image will lie in a straight line in accordance to the original position. So, the second image is Lance's image.

When a figure is rotated 90 degrees counterclockwise, this means the figure will turn to the left and the point of the figure will be downwards. So, the first image is Celina's image.

one way is to factor the expressions

(a)

[tex]10^{5}[/tex] (1.2 + (5.35 × [tex]10^{1}[/tex]))

= [tex]10^{5}[/tex] (1.2 + 53.5)

= 54.7 × [tex]10^{5}[/tex] = 5.47 × [tex]10^{1}[/tex]× [tex]10^{5}[/tex] = 5.47 × [tex]10^{6}[/tex]

(b)

[tex]10^{-3}[/tex]((6.91 × [tex]10^{1}[/tex]) + 2.4)

= [tex]10^{-3}[/tex](69.1 + 2.4)

= 71.5 × [tex]10^{-3}[/tex] = 7.15 × [tex]10^{1}[/tex] × [tex]10^{-3}[/tex] = 7.15 × [tex]10^{-2}[/tex]

(c)

[tex]10^{5}[/tex]((9.7 × [tex]10^{1}[/tex]) + 8.3)

= [tex]10^{5}[/tex](97 + 8.3)

= 105.3 × [tex]10^{5}[/tex] = 1.053 × [tex]10^{2}[/tex] × [tex]10^{5}[/tex] = 1.053 × [tex]10^{7}[/tex]

(d)

[tex]10^{1}[/tex]((3.67 × [tex]10^{1}[/tex]) - 1.6)

= [tex]10^{1}[/tex](36.7 - 1.6)

= 35.1 × [tex]10^{1}[/tex] = 3.51 × [tex]10^{1}[/tex] × [tex]10^{1}[/tex] = 3.51 × [tex]10^{2}[/tex]

(e)

[tex]10^{-6}[/tex]((8.41 × [tex]10^{1}[/tex]) - 7.9)

= [tex]10^{-6}[/tex](84.1 - 7.9 )

= 76.2 × [tex]10^{-6}[/tex] = 7.62 × [tex]10^{1}[/tex] × [tex]10^{-6}[/tex] = 7.62 × [tex]10^{-5}[/tex]

(f)

[tex]10^{4}[/tex]((1.33 × [tex]10^{1}[/tex]) - 4.9 )

= [tex]10^{4}[/tex](13.3 - 4.9) = 8.4 × [tex]10^{4}[/tex]

11. Opposite rays are rays that together make a line. The only point they have in common is their mutual end point.

Given the letter names of points on lines, one can name opposite rays by choosing 3 collinear points, and selecting the middle one of those for the mutual end point. That point's name will be the first letter of each of the ray names. One ray will be named by one of the remaining points, and the other will be named by the other remaining point.

Here, we can choose points H, O, D on the same line. Then rays in opposite directions will be OD and OH, each having point O as its end point.

Similarly, we can choose points B, O, J on the other line and name opposite rays OB and OJ.

13. The unadulterated triangle has legs of 6 and 8 units, so an area of ...

... area = (1/2)bh = (1/2)(6)(8) = 24 . . . . square units.

One can count the squares within that area that have been removed from the triangle. There are 7 of them, so the area is ...

... 24 -7 = 17 . . . . square units

There are other ways to find the area, including dividing the triangle into smaller pieces. Doing the latter, one needs to be careful, because the slanted side only goes through a grid intersection at points (1, 1), (4, 5), and (7, 9).

If one uses two triangles with legs 3 and 4, and a central rectangle of 2×3, then the area adds up to 6+6+5 = 17 square units, because there is one square taken out of the lower right corner of the upper triangle.

If you multiply the original equation by 8, you get

... 8(1/4x -1/2y) = 8(8)

... 8/4x -8/2y = 64

... 2x -4y = 64 . . . . . matches choice b)

A) The time to travel 45 miles at a speed of 40 mph can be found from ...

... time = distance / speed

... time = (45 mi)/(40 mi/h) = 9/8 h = 1 hr 7 min 30 sec

B) The gas consumption can be found from ...

... (45 mi)/(54 mi/gal) = 5/6 gal

C) The cost of gas can be found from ...

... ($3.23/gal)×(5/6 gal) ≈ $2.69

Answer:

Card 7

The hourly rate of change/slope is $75 per hour.

Card 8

Frastastic is charging $0.48 per ounce.

Step-by-step explanation:

Card 7

Lets take the set up fee as "$[tex]s[/tex]" and,

Hourly rate as $[tex]x[/tex]per hour.

Now we can write equations for 3 hour event and 5 hour event.

[tex]s+3x=275[/tex] <------- (1)

[tex]s+5x=425[/tex] <------- (2)

Now we need to solve the simultaneous equations to find [tex]s[/tex] and [tex]x[/tex].

Subtract (1) from (2)

⇒[tex]s+5x-(s+3x)=425-275[/tex]

[tex]s+5x-s-3x=150[/tex]

[tex]2x=150[/tex]

[tex]x=75[/tex]

So the hourly rate of change/slope is $75 per hour.

Therefore, Raymond is right.

Card 8

You can take Amount (oz) as x values and Cost as y values and plot a graph.

Then the Slope of the graph will give you the rate Frastastic is charging per yogurt.

Slope of a linear graph is given by the following equation;

Slope(m)=[tex]\frac{y_{1}-{y_{2}}}  {x_{1}-x_{2}   }[/tex]

Slope(m)=[tex]\frac{6.72-2.4}{14-5}[/tex]

Slope(m)=[tex]\frac{4.32}{9}[/tex]

Slope(m)=[tex]0.48[/tex]

Therefore, Frastastic is charging $0.48 per ounce.

This is less than $0.50 per ounce charged by Fromazing. Therefore, Sterling is right.
