Remark
I really don't know what to write to these questions. I can never tell what the problem is. Perhaps it is right at the very beginning. You have to recognize what is taking place. In problem 9, the easiest point to follow is H going to H'. Do you see what is happening? H is sitting on the x axis and then something happens to it and behold, it is now sitting on the y axis. So it has rotated 90 degrees but which way?
Take your finger or a pencil and put it on H. Then make a circular motion to get to H'. You are going clockwise. (keep going in that direction till you wind up where you started. You are going in the direction of one of those old fashioned clocks. Now the trick in a rotation is if you can figure out what one point is doing, you know what all points are doing on the given figure.
So the translation is 90 degrees clockwise. That means the following rule must be operating
(x,y) ===> (y, - x)
H(-3,0) ===> H'(0, - - 3) = H'(0,3)
I(-2,1) =====>I'(1, - - 2) = H'(1,2)
J(0,1) =====>J'(1,0)
G(-3,-3)====>G'(-3, --3) = G'(-3,3)
11
At first you may think that this is a translation of some kind. I thought so at first. D and D' certainly look that way and C and C' also look that way. But B and E are not well behaved. You are looking at a 180 degree rotation
The rule you need here is (x,y) becomes (-x , - y)
I'll leave C and D to you and do one of the B and E
E(3,5)=E'(-3 , - 5)

Answer:
9) (x, y) ⇒ (y, -x) . . . . rotation 90° CW
11) (x, y) ⇒ (-x, -y) . . . rotation 180°
Step-by-step explanation:
9) Distance from the origin to an image point is the same as to the preimage point, but the direction is changed by 90° in the CW direction. For example, J is north of the origin, but J' is east, a direction change of 90° CW.
The transformation describing a 90° CW rotation is the rule ...
(x, y) ⇒ (y, -x)
__
11) Distance and direction to each image point from the origin are equal and opposite of distance and direction to the preimage point. The figure has been rotated 180°. The corresponding rule is ...
(x, y) ⇒ (-x, -y)

1. What is 1 1/2 + 3/4
Answers
Answer:
2 1/4
Step-by-step explanation:
First, for adding, subtracting, and comparing fractions, it is good to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators = LCM ⇒ (2, 4) = 4. We should do = three halfs + three quarters = nine quarters. Thus, 2 1/4 or 2.25 is the answer.
1 1/2 + 3/4 = 9/8 = 2 1/4 or 2.25

Answers
Answer:
465 I think is the answer
% / 100 = Part / Whole
replace the given values:
85 / 100 = Part / 620
Cross multiply:
= 85 x 620 = 100 x Part
= 52700 = 100 x Part
Now, divide by 100 and get the answer:
Part = 52700 / 100 = 527

Answers
Answer:
The correct answer is 24
Step-by-step explanation:
K12 test
figure has two intersecting lines and a ray.
From this figure, the value of x= 24
Given :
Two intersecting lines and a ray. one angle is 110 degrees.
opposite to 111 degrees are 87 and x degrees
From the two intersecting lines, we know that vertical opposite angles are equal .
111 degrees and 87+x are vertical opposite angles
So, they are equal .
Lets make them equal and solve for x
[tex]111=87+x[/tex]
Now we subtract 87 on both sides and solve for x
[tex]111-87=87-87+x\\\\x=24[/tex]
So the value of x is 24 degrees

m < 105° = m < 10x° + 15 °
Subtract 15 from both sides:
m < 105° - 15° = 10x°
90° = 10x°
Divide both sides by 10 to solve for x:
90°/10 = 10x/10
9° = x
Therefore, the value of x = 9°
Substitute this value into m < (10x + 15)° to find its true measure:
10(9) + 15 = 90 + 15 = 105°
This proves my statements earlier that m < 105° has the same measure as m < (10x + 15)°
The correct answer is x = 9°

y=-2/5x-1
Step-by-step explanation:
I started by looking for the y-intercept of the line, where the line intersects with the y-axis and saw it was -1.
Then I looked at the slope of the line and used the rise/run strategy. From the y-intercept to the point it was 2 units down and 5 units across (2/5) and since it is going down it's negative
Plugging it in: y=mx+b
m=slope
b=y-intercept

2: 4,000 composite units
Step-by-step explanation:
We assume your "composite unit" consists of the smallest set of units in the ratio in which they are sold.
1)A "composite unit" is 1B +2A. The contribution margins are the difference between the selling price and the variable cost per unit:
A: 72 -40 = 32
B: 48 -28 = 20
composite unit: 2A+B = 2(32) +20 = 84
(a) The contribution margin per composite unit is $84.
__
(b) The break-even point is the number of composite units that have a total contribution margin equal to the total fixed costs:
84n = 1260000
n = 1260000/84 = 15000
30,000 units of A and 15,000 units of B must be sold to break even.
__
(c) The additional number of composite units required to achieve pre-tax income of 294000 is ...
294,000/84 = 3500
37,000 units of A and 18,500 units of B must be sold for a pretax income of $294,000.
__
2)Contribution margins per unit are ...
H: 6 -4 = 2
C: 8 -6 = 2
I: 10 -7 = 3
A composite unit is 3H +2C +I, so the contribution margin per composite unit is ...
3(2) +2(2) +1(3) = 6 +4 +3 = 13 . . . dollars
The break-even point is 52,000/13 = 4,000 composite units

What is Parallel line?Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.As, Parallel line have property
Any two lines are considered to be parallel if the angles formed by them are equal.If the Opposite interior angles formed by two lines are equal, they are said to be parallel.If the Opposite exterior angles formed by two lines are equal, they are said to be parallel.If the Successive interior angles on the same side of the transversal are additional, two lines are said to be parallel.As, <CBA = <BAD (Alternate Interior Angle)
So, <BAD = 42
Now, <BAD + <BAC + <CAE = 180 (Linear Pair)
42 + 109 + x = 180
151 +x = 180
x = 180- 151
x = 29

Define the function

g(x) = x^3+ x
. If

and
f(2) = 1
what is the value of
f'(2)
?
Answers
Given that
[tex]g(x) = x^3 + x[/tex]
the inverse [tex]g^{-1}(x)[/tex] is such that
[tex]g\left(g^{-1}(x)\right) = g^{-1}(x)^3 + g^{-1}(x) = x[/tex]
or
[tex]g\left(f(x)\right) = f(x)^3 + f(x) = x[/tex]
Differentiating both sides using the chain rule gives
[tex]3f(x)^2f'(x) + f'(x) = 1 \\\\ f'(x) \left(3f(x)^2+1\right) = 1 \\\\ f'(x) = \dfrac1{3f(x)^2+1}[/tex]
Then the derivative of f at 2 is
[tex]f'(2) = \dfrac1{3f(2)^2+1} = \boxed{\dfrac14}[/tex]
