Find the area of triangle XYZ if length XY equals 7 and length XZ equals 4.3. You also
know that angle Y equals 79°.
Answers
Answer:
A ≈ 14.8 units²
Step-by-step explanation:
the area (A) of the triangle is calculated as
A = \(\frac{1}{2}\) yz sin Y ( that is 2 sides and the angle between them )
where x is the side opposite ∠ X and z the side opposite ∠ Z
here y = XZ = 4.3 and z = XY = 7 , then
A = \(\frac{1}{2}\) × 4.3 × 7 × sin79°
= 15.05 × sin79°
≈ 14.8 units² ( to 1 decimal place )

if the point p falls on the unit circle and has an x coordinate of 5/13 find the y coordinate of point p
Answers
To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.
The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:
x^2 + y^2 = 1
Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:
(5/13)^2 + y^2 = 1
25/169 + y^2 = 1
To isolate y^2, we subtract 25/169 from both sides:
y^2 = 1 - 25/169
y^2 = 169/169 - 25/169
y^2 = 144/169
Taking the square root of both sides, we find:
y = ±sqrt(144/169)
Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:
y = ±12/13
So, the y-coordinate of point P can be either 12/13 or -12/13.

Answers
The ponderal index cannot be computed without the value of the constant "a" in the formula. Therefore, the ponderal index for a person who is 76 inches tall and weighs 192 pounds cannot be determined.
To compute the ponderal index, we need the formula and the value of the constant "a."
a) The formula for the ponderal index is given as I = a, where I represents the ponderal index and a is a constant. However, the value of the constant "a" is missing in the provided information. Without knowing the value of "a," we cannot compute the ponderal index for a person who is 76 inches tall and weighs 192 pounds.
b) Similarly, without knowing the value of the constant "a," we cannot determine the weight of a man who is 77 inches tall and has a ponderal index of 11.56.
To compute the ponderal index or determine the weight, we need the specific value of the constant "a" in the given formula.

Answers
The relationship will be a solid line .
How to find the relationship between the given amounts?
Given:
The amount of one lunch =$4
The amount of the school lunch card=$100
Let, the amount remaining on the card= b
Let the number of lunches to buy = a
The equation is given by,
b = 100 - 4a
When 1 lunch is bought ,a= 1 ;
b= 100 - 4(1) = 96
When 2 lunches are bought ,a= 2;
b= 100 - 4 (2)= 92
When 3 lunches are bought ,a= 3;
b= 100 - 4 (3)= 88

in hire-assistant, assuming that the candidates are presented in a random order, what is the probability that you hire exactly one time? what is the probability that you hire exactly n times?
Answers
In hire-assistant, assuming that the candidates are presented in a random order, the probability of hiring exactly one time is 1/n, while the probability of hiring exactly n times is 1/n!.
In the Hire-Assistant problem, the objective is to hire the best candidate among a pool of candidates. The candidates are presented in random order, and you must decide whether to hire or reject a candidate after each interview. The hiring process ends when the best candidate is hired.
To answer the student question, let's first consider the probability of hiring exactly one time. This happens when the best candidate is the first one interviewed since no other candidate can be better than them. Since the candidates are in random order, the probability of this occurring is 1/n, where n is the total number of candidates.
Now let's consider the probability of hiring exactly n times. This means you would hire every candidate you interview. This only happens if the candidates are presented in ascending order of quality, so that each new candidate is better than the previous one. There is only 1 possible ordering like this out of the total n! possible orderings of candidates. So, the probability of hiring exactly n times is 1/n!.
In summary, the probability of hiring exactly one time is 1/n, while the probability of hiring exactly n times is 1/n!. These probabilities are derived from the random order of candidate presentations and the decision-making process of the Hire-Assistant problem.

tables
Answers
The total number of tables in Waterview Grille is 50 tables when 60% tables are reserved.
What are percentages?A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. Thus, a part per hundred is what the percentage refers to. Percent signifies for every 100.
The value must be divided by the entire value, and the resulting number must then be multiplied by 100 to get the percentage.
Formula for percent: 100 divided by (value/total value).
Given that the tables reserved are 30.
The reserved tables are 60 % of the total tables.
T (60/100) = 30
T = 30(100) / 60
T = 50

Gonzalez Manufacturing borrowed $21000. Part of the money was borrowed at 10%, part at 12%, and part at 14%. The total amount borrowed at 10% and 12%
was twice the amount borrowed at 14%. Find the amount borrowed at each rate if the annual interest was $2580
How much money was borrowed at 10%?
How much money was borrowed at 12%?
How much money was borrowed at 14%?
Answers
Answer:
10% — $550012% — $700014% — $8500Step-by-step explanation:
You want to know the amount borrowed at 10%, 12%, and 14% if the total borrowed was $21000, the total interest was $2580, and the total of amounts borrowed at 10% and 14% was double the amount borrowed at 12%.
EquationsThe relations give rise to three equations. If we let x, y, z represent the respective amounts borrowed at 10%, 12%, and 14%, we have ...
x + y + z = 21000 . . . . . . total borrowed
0.10x +0.12y +0.14z = 2580 . . . . . . total interest
x + y = 2z . . . . . . . . . . . relationship between amounts
Writing the last equation as ...
x -2y +z = 0
we can formulate the problem as a matrix equation and use a solver to find the solution. We have done that in the attachment. It tells us the amounts borrowed are ...
10% — $550012% — $700014% — $8500__
Additional comment
Recognizing that the amount at 12% is 1/3 of the total, we can use that fact to rewrite the other two equations. The interest on the $7000 at 12% is $840, so we have ...
x + y = 140000.10x +0.14y = 1740These two equations have the solution shown above. (It is usually convenient to solve them by substituting for x in the second equation.)

Answers
In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between zero and one.
What is 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).
In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between zero and 1.
The image is contracted if the scale factor is less than 1 (0< k <1).
The image is enlarged if the scale factor is more than 1 (k > 1).
The image remains the same if the scale factor is 1 (k = 1).
Hence, the scale factor k should be between 0 and 1.
