sec(A) = 5/3 ⇒ cos(A) = 3/5
Angles A and C are complimentary (they sum to 90°), so
sin(C) = cos(A) = 3/5
since sin(90° - x) = cos(x) for all x, and in turn
csc(C) = 1/sin(C) = 5/3
What composition of rigid motions maps ΔPQR to ΔXZY?
A. T<1, 3> ◦ r(270°, O)
B. Rx = 0 ◦ T<0, 2>
C. T<6, 2> ◦ Rx = −2
D. Ry = −2 ◦ T<6, 0>
Answer:
reflection across x=1, translation up 2
units
Step-by-step explanation:
The order of vertices PQR is
clockwise, and the order of XZY
is counterclockwise. This means a
reflection is involved. The longest and
shortest sides are at the left and bottom
of APQR, and at the right and bottom
of AXZY, indicating the reflection is
left-right, not up-down.
Line x=1 contains the midpoints of
segments PX, QZ, and RY, so that is a
suitable line of reflection. Once APQR
is reflected over that line, it needs to be
translated upward 2 units to coincide
with AXZY.
The motions are ...
.
reflection over x=1
translation up 2
.
The motions could also be ...
reflection over y, translation right 2 and
up 2.
ANSWER
The composition of rigid motions maps ΔPQR to ΔXZY is T<6, 2> ◦ Rx = −2. The correct option is C.
What are rigid motion maps?In rigid motion, the position or orientation of the entire set changes without affecting the separation between the line segments. A triangle, for instance, can turn or slide but not extend or squeeze.
PQR's vertices are in clockwise and XZY's are in a counterclockwise sequence. This indicates that a reflection is necessary. The reflection is left-right, not up-down, as evidenced by the longest and shortest sides being on the left and bottom of A PQR, and on the right and bottom of AXZY, respectively.
The midpoints of the segments PX, QZ, and RY are on line x=1, making it a viable line of reflection. To match with AXZY, APQR must be translated upward 2 units after crossing that line.
Therefore, the correct option is C. T<6, 2> ◦ Rx = −2.

Larousse Language College will have 201 students in the Sixth Form next year. Mr Roche, who
does the timetabling, knows that between 70% and 75% of the students intend to study French
and between 40% and 50% of the students intend to study German. All students study either
French or German or both.
By using Venn diagram method, the smallest and the largest number of students that intend to study both French and German are 21 and 49 students respectively.
Given that Larousse Language College will have 201 students in the Sixth Form next year. And between 70% and 75% of the students intend to study French. Also, between 40% and 50% of the students intend to study German.
If all students study either French or German or both, the least number of students that will study French will be
70/100 x 201
140. 7
Which means 141 students
The least number of students that will study German will be
40/100 x 201
80.4
That means 81 students
Also, the maximum number of students that will study French will be
75/100 x 201
150.75
That is 150 students ( Because approximation can't be done twice)
And the maximum number of students that will study German will be
50/100 x 201
100 students ( Because approximation can't be done twice)
a.) The smallest number of students that intend to study both French and German can be calculated as followed
Let the smallest number be x
141 - x + x + 81 - x = 201
222 - x = 201
- x = 201 - 222
-x = - 21
x = 21
b.) The largest number of students that intend to study both French and German can be calculated as followed
Let the largest number be y
150 - y + y + 100 - y = 201
250 - y = 201
- y = 201 - 250
-y = - 49
y = 49
Therefore, The smallest and the largest number of students that intend to study both French and German are 21 and 49 students respectively.

Use the FOIL method to find the terms of the following multiplication problem.

Answer:
FOIL = First terms, outer terms, inner terms, and last terms. The product of the first terms is 24 (4*6). The product of the outer terms is -12i(4*-3i). The product of the inner terms is 18i(3i*6). The product of the last terms is -9i^2(3i*-3i). "i^2"= -1 So, -9*-1= 9.
1. f(x) = 2x^3 -3x. If h(x) is the inverse function of f, then h'(-1) =
I believe the correct answer is 1/3, but I don't know how to get it.
If f and h are inverses of one another, then we have
h(f(x)) = x
Differentiating both sides using the chain rule gives
h'(f(x)) • f'(x) = 1
Let f(x) = -1. Then it would follow that
h'(-1) = 1/f'(x)
for the value of x such that f(x) = -1. This result is known as the inverse function theorem.
Solve for x such that f(x) = -1 :
2x³ - 3x = -1
2x³ - 3x + 1 = 0
By inspection, x = 1 is a solution, since 2 - 3 + 1 = 0. So x - 1 is a factor of the left side; polynomial division yields a factorization of
(x - 1) (2x² + 2x - 1) = 0
and using the quadratic formula, we find three solutions,
x = 1, x = (-1 - √3)/2, x = (-1 + √3)/2
Since there's more than one solution here, this means f(x) is not one-to-one and thus has no inverse in the strict sense of the term.
We can however restrict the domain of f(x) to a subset over which it can be inverted. Using the fact that polynomials are monotonic over intervals between their extrema, we find the critical points of f(x) :
f'(x) = 6x² - 3 = 0 ⇒ x² = 1/2 ⇒ x = ± 1/√2
Check the sign of the second derivative at each critical point:
f''(x) = 12x
• f''(-1/√2) = -12/√2 < 0 ⇒ x = -1/√2 is a local maximum
• f''(1/√2) = 12/√2 > 0 ⇒ x = 1/√2 is a local minimum
Now we have a few choices of how to define the inverse of f(x).
• If we restrict the domain of f(x) to the interval (-∞, -1/√2), then f(x) = -1 when x = (-1 - √3)/2. Then by the inverse function theorem,
f((-1 - √3)/2) = -1 ⇒ h'(-1) = 1/f'((-1 - √3)/2) = (-1 + √3)/6
• If we instead restrict the domain to (-1/√2, 1/√2), then f(x) = -1 when x = (-1 + √3)/2. Then
f((-1 + √3)/2) = -1 ⇒ h'(-1) = 1/f'((-1 + √3)/2) = (-1 - √3)/6
• Otherwise, if we restrict to (1/√2, ∞), then f(x) = -1 when x = 1. Then
f(1) = -1 ⇒ h'(-1) = 1/f'(1) = 1/3

what were georgia's after the proclamation of 1763
Answer:
The Proclamation of 1763 was issued by the British at the end of the French and Indian War to appease Native Americans by checking the encroachment of European settlers on their lands. It created a boundary, known as the proclamation line, separating the British colonies on the Atlantic coast from American Indian lands west of the Appalachian Mountains. In the centuries since the proclamation, it has become one of the cornerstones of Native American law in the United States and Canada.

In a cluster sample:
A. a subset of naturally occurring groups are randomly sampled.
B. an alphabetic list of individuals is used for random selection into
the sample.
C. individuals are distinguished based on some characteristic such
as gender before they're randomly selected from the population.
D. only convenient members of the population are chosen.
E. None of the above
In a cluster sample only convenient members of the population are chosen. The correct option is D.
What is cluster?In cluster sampling, a population is divided into clusters, which are smaller groups. They then choose a sample at random from these clusters.
Often employed to investigate huge populations, particularly those that are extensively geographically distributed, cluster sampling is a probability sampling technique.
Large, dispersed populations should be studied using cluster sampling because interviewing every individual would be expensive, time-consuming, and possibly impossible.
Cluster sampling enables the construction of smaller, more similar representations of the population being studied. Only practical population members are picked for a cluster sample.
Thus, the correct option is D.

Now, while the world is bent my deeds to cross,
Join with the spite of fortune, make me bow,
And do not drop in for an after-loss:
(5) Ah, do not, when my heart has 'scaped this sorrow,
Come in the rearward of a conquered woe;
Give not a windy night a rainy morrow,
To linger out a purposed overthrow.
If thou wilt leave me, do not leave me last,

But in the onset come, so shall I taste
At first the very worst of fortune's might;
And other strains of woe, which now seem woe,
Compared with loss of thee, will not seem so.

Shakespeare uses a variety of poetic devices in "Sonnet 90." These include metaphor, caesura, and alliteration, among others. When words that start with the same sound are used consecutively or even just near to one another, alliteration develops.
When a line is cut in two, sometimes with punctuation and other times without, this is known as a caesura. Punctuation in these places causes a highly deliberate stop in the text.
