The required angles ∠TBS and ∠TCV are 48° and 22° respectively.
What is right angled triangle ?A right-angled triangle is a kind of triangle that has one of its points equivalent to 90 degrees. The other two points summarize to 90 degrees. The sides that incorporate the right point are opposite and the foundation of the triangle. The third side is known as the hypotenuse, which is the longest side of each of the three sides
According to question:∠TBV = 24°
∠VBS = 24°
So, ∠TBS = (24° ) = 48°
And,
∠SAU = 92°,
So,
∠VAU = 46°
In ΔTAC
∠TAC + ∠TCA = 90°
∠TCA = 90° - 46° = 44°
This angle is bisect by CV
Then,
∠TCV = 44/2 = 22°

What is a angle bisector?
In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an object or a shape into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.
As given in question:
AV , BV and CV are the angle bisector of ΔABC
UV = 17, BV = 18
∠SAU =92° and ∠TBV = 24°
Now,
∠TBV = ∠SBV = 24° ( BV is angle bisector)
So, ∠TBS = ∠TBV + ∠SBV
∠TBS = 24° + 24° = 48°
SV = UV = 17 (V is the incenter of ΔABC.)
∠SAU + ∠TBS + ∠TCU = 180° (Sum of angles of a triangle)
92° + 48° + ∠TCU = 180°
∠TCU = 180° - 140°
∠TCU = 40°
So, [tex]\angle TCV = \frac{40\degree}{2}[/tex]
∠TCV = 20°
∴ ∠TBS = 48°
SV = 17
∠TCV = 20°

Answers
Inequality that could be used to solve for x is;
1450 words + (265 words / day)x = 3305 words
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given that Amy has already written 1450 words out of 3305 words.
And she writes at the rate of 265 words per day.
To establish the inequality which could be used to solve for x,
Then Firstly, we will form an equation for the total number of days required to write her paper,
1450 words + (265 words / day)x = 3305 words.
Simplifying the above expression,
(265 words / day)x = 3305 words - 1450 words
To solve this linear equation, we'll find x = 7.
x = { 3305 words - 1450 words} / 265 words
x = 7 days.
Hence, inequality that could be used to solve for x is;
1450 words + (265 words / day)x = 3305 words

What is the scale factor?
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.
13.5 / 9 = 1.5
9 * 1.5 = 13.5 \s12 * 1.5 = 18
You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)

what is percentage ?By dividing the value by the entire value and multiplying the result by 100, one can compute the percentage. The formula for calculating percentage is (value/total value)100%.When a piece of a whole is stated as a percentage, it is not a fraction but rather a number between 0 and 100. There are three percentages: 100% for everything, 50% for half of it, and 0% for the remaining portion.
calculation
25% of new students come from one-parent households, which equals 0.25;
75% of new students come from two-parent households, which is 0.75.
42% of incoming students from homes with only one parent go on to complete their college studies = 0. 42
58 percent of incoming students who come from two-parent households go on to complete their education =0.58
= 0.25 * 0.42 + 0.75 * 0.58 = 0.54 = 54%.

What is a perimeter?
The perimeter of a two-dimensional shape is the distance around the outside of the shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is the sum of the lengths of all four sides. The perimeter of a triangle is the sum of the lengths of all three sides.
To reflect a point across the line y=x, we can use the following formula:
(x', y') = (y, x)
Where (x', y') is the reflected point and (x, y) is the original point.
Using this formula, we can find the coordinates of the reflected points A' and B':
A' = (4, 4) -> (4, 4) -> (4, 4)
B' = (5, -1) -> (-1, 5) -> (-1, 5)
Therefore, the image of AB is A'B' with endpoints A'(4, 4) and B'(-1, 5).
To find the perimeter of the figure formed by the segments AB, B'B, and A'B', we can add up the lengths of these three segments. The length of AB can be found using the distance formula:
[tex]AB = \sqrt{((5-4)^2 + (-1-4)^2)}\\\\= \sqrt{(1^2 + (-5)^2)}\\\\= \sqrt{(1 + 25)}\\\\= \sqrt{26}[/tex]
The length of B'B can be found using the same formula:
[tex]B'B = \sqrt{((-1-(-1))^2 + (5-5)^2)}\\\\= \sqrt{(0^2 + 0^2)}\\\\= 0[/tex]
The length of A'B' can also be found using the distance formula:
[tex]A'B' = \sqrt{((-1-4)^2 + (5-4)^2)}\\\\= \sqrt{(-5)^2 + (1)^2}\\\\= \sqrt{25 + 1}\\\\= \sqrt{26}[/tex]
The perimeter of the figure is AB + B'B + A'B' = √26 + 0 + √26 = 2√26. To the nearest tenth, this is 5.0.
Hence, the perimeter of the figure is 5.0.

The coordinates of the centroid of triangle DEF with the vertices (0,4) (6,6), and (2,2) is calculated as: (8/3, 4).
How to Find the Coordinates of the Centroid of a Triangle?The formula for finding the coordinates of the centroid of a triangle is given as:
C(x, y) = [tex]( \frac{(x1+x2+x3)}{3}, ( \frac{(y1+y2+y3)}{3})[/tex].
Given the vertices of triangle DEF as follows:
D (0, 4) = [tex](x_1, y_1)[/tex]
E (6, 6) = [tex](x_2, y_2)[/tex]

Substitute the values into the centroid formula to find the coordinates:
C(x, y) = [(0 + 6 + 2)/3, (4 + 6 + 2)/3]
C(x, y) = (8/3, 12/3)

27 -18 = 9
These are not constant, so the sequence is not an arithmetic sequence.

18/12 = 1.5
27/8 = 1.5
These are constant, suggesting the sequence is an exponential sequence. The equation for the n-th term is ...

The sequence could be quadratic if the second differences are all 9-6=3. In that case, the equation for the n-th term is ...

y = (3/2)x - 7To graph a line we need two points, one is given, (0, - 7) - the y-intercept.
Find one more point, take even value of x to cancel the fraction, let it be x = 4, find its y-coordinate:
y = (3/2)*4 - 7 = 6 - 7 = - 1So our points are:
A(0, - 7) and B(4, - 1)Plot the points and connect to graph the line.
See below.
The graph of the linear equation:y = (3/2)*x - 7 can be seen in the image at the end.
How to graph the linear equation?A general linear equation is written as:y = a*x + b
Where a is the slope and b is the y-intercept. Then our linear equation is:y = (3/2)*x - 7
To graph it, we need to know two points in our line, to do so, we evaluate it in two different values of x. if x = 0y = (3/2)*0 - 7y = -7So we have the point (0, -7)
And if x = 2 then:y = (3/2)*2 - 7y = 3 - 7y = -4So we have the point (2, -4)

Step-by-step explanation:
A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Tyler's bank account pays a straightforward yearly financing cost of 3.25%. Assume he stores $5,000 in the record and sets aside no extra installments or withdrawals for a long time.
The total value of the account after 3 years will be calculated as,
