16. Determine if the functions represent even, odd, or neither.
Answer:
a) even
b) neither
c) odd
Step-by-step explanation:
A function is "even" when there is symmetry about the y-axis.
Functions are symmetric with respect to the y-axis if for every point (a, b) on the graph, there is also a point (-a, b) on the graph:
f(x, y) = f(-x, y)A function is "odd" when there is origin symmetry.
Functions are symmetric with respect to the origin if for every point (a, b) on the graph, there is also a point (-a, -b) on the graph:
f(x, y) = f(-x, -y)Graph aFrom inspection of the graph, the curve appears to be symmetrical about the y-axis. Therefore, the function is even.
Graph bThis is an absolute value function. It has no symmetry about the y-axis or the origin. Therefore, the function is neither.
Graph cFrom inspection of the graph, the curve appears to be symmetric with respect to the origin. Therefore, the function is odd.

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 5 units long. Point C is on the line x = −2. If the area of ΔABC is 12.5 square units, then find a possible y-coordinate of point C.
POSSIBLE ANSWER CHOICES:
a. 5
b. 6
c. 7
d. 8
Answer:
5
Step-by-step explanation:
The possible value of y-coordinate of the point C will be 5 or -1.
Given information:
Right triangle ABC is on a coordinate plane.
Segment AB is on the line y = 2 and is 6 units long.
Point C is on the line x=−3.
The area of triangle ABC is 9 square units.
AB is on the line y=2 which is parallel to the x-axis. So, AB will be parallel to x-axis.
Point C is on the line which is parallel to y-axis. So, side BC or AC will be parallel to y-axis.
So, AB will be perpendicular to the other side containing point C (BC or AC). From this, the y-coordinate of the point C should be such that the length of the side or leg containing C should justify the area of the triangle.
The length of other leg of the triangle should be,
So, the y-coordinate of the point C can be,
Therefore, the possible value of y-coordinate of the point C will be 5 or -1.

Answer:
5
Step-by-step explanation:
Triangle Area formula
A = 1/2(b)(h)
We have the area of the triangle = 12.5 and the base, or height = 5
12.5 = 1/2 (5)(h) OR 12.5 = 1/2(b)(5)
(switching base/height doesnt work for everything)
12.5 = 2.5h OR 12.5 = 2.5b
12.5/2.5 = 2.5h/2.5 OR 12.5/2.5 = 2.5b/2.5
5 = h, 5 = b
5 · 5 = 25
25/2 = 12.5
This is just how I did it, you would use the distance formula, but since I didn't have coordinates, I checked my answer like this, you could always substitute coordinates that fit the description for the question.
So, the answer is 5.

Simplify to a single trig function or constant with no fractions.
We can simplify cosec(t)tant(t) to sec(t). A trigonometric function is a mathematical function that relates the angles of a triangle to the ratios of its sides.
The most common trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
To simplify the expression cosec(t)tant(t), we need to use the trigonometric identity:
cosec(t) = 1/sin(t)
tant(t) = sin(t)/cos(t)
Substituting these expressions into the original expression, we get:
cosec(t)tant(t) = (1/sin(t))(sin(t)/cos(t))
The sin(t) term in the numerator and denominator cancel out, leaving:
cosec(t)tant(t) = 1/cos(t)
Recalling the definition of secant, sec(t) = 1/cos(t), we can express the simplified expression as:
cosec(t)tant(t) = 1/sec(t)
Therefore, we can simplify cosec(t)tant(t) to sec(t).

According to a NY Times article in 2009, the average selling price of an LCD TV was $700. What would be the cost of that same TV in 2016 dollars?
The prices of products usually fall due to depreciation and the appearance of new technological objects. In this case, the value of the television would lower its price due to the appearance of other technologies such as LED.
How to calculate LCD TV depreciation?To calculate the depreciation of the LCD TV, the year of manufacture, the useful life, the prices of new products (generally better), among others, must be taken into account.
A ballpark figure of 15% is generally used to calculate the depreciation of a television per year. In this case, following this pattern, the television would have a value of:

The lengths of the sides of a right triangle are three consecutive integers, right, and solve an equation to find the three integers
The only possible solution is x = 2. Therefore, the three consecutive integers that form the sides of the right triangle are 2, 3, and 4.
How to find side of triangle?Since they are consecutive integers, let's assume that the hypotenuse, which is the longest side of the right triangle, is x+2, as it is three units longer than the shortest side.
In a right triangle, the hypotenuse's square is equal to the sum of the squares of the other two sides, according to the Pythagorean theorem. We can thus write:
\((x+2)^2 = x^2 + (x+1)^2\)
Expanding the squares, we get:
\(x^2 + 4x + 4 = x^2 + x^2 + 2x + 1\)
Simplifying and rearranging terms, we get:
\(2x^2 - 2x - 3 = 0\)
We can solve this quadratic equation by using the quadratic formula:
x = (-b ± \(\sqrt{b^2 - 4ac}\)) / 2a
where a = 2, b = -2, and c = -3.
Plugging in these values, we get:
x = (-(-2) ± \(\sqrt{((-2)^2 - 4(2)(-3)))\) / 2(2)
x = (2 ± \(\sqrt{(4 + 24))\) / 4
x = (2 ± \(\sqrt28}\) / 4
x = (2 ± \(2\sqrt{7}\)) / 4
x = 1/2 ± \(\sqrt{7}\)/2
The only option is x = 2, since x must be an integer. As a result, the numbers 2, 3, and 4 are the three consecutive integers that make up the sides of the right triangle.

The value of x and y are 8\(\sqrt{2}\), we can solve this question by Pythagoras' Theorem.
What is Pythagoras' Theorem?Pythagoras' Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be written as: \($a^2 + b^2 = c^2$\)
where 'a' and 'b' are the lengths of the legs (the sides adjacent to the right angle) and 'c' is the length of the hypotenuse. This theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery and proof. It has a wide range of applications in geometry, trigonometry, and other areas of mathematics and science.
By using Pythagoras' theorem, we get
\(sin 45=\frac{x}{16}\)
\(\frac{1}{\sqrt{2} }\) =\(\frac{x}{16}\)
\(x=8\sqrt{2}\)
\(cos 45=\frac{x}{16}\)
\(\frac{1}{\sqrt{2} }\)=\(\frac{y}{16}\)
\(y=8\sqrt{2}\)
So, the values of x and y are 8\(\sqrt{2}\)

Step-by-step explanation:
To solve we must first distribute the 5 to everything that is inside the parenthesis. To do this we can multiply 5×3x = 15x and 5×-2 = -10.We can then combine these new numbers and set them equal to 6.
5(3x-2) ---> 15x-10=6
From here we need to get the x on one side all alone. To do this we need to first move the -10. We can add 10 to both sides.
15x=6+10

15x=16
Then we can divide both sides by 15 to get x alone

there are 36 pupils in a class.the number of boys is twice the number of girls.how many are girls?
Answer:
12 girls
Step-by-step explanation:
Boys to girls ratio= 1:2
Thats means there are (1+2) 3 total parts.
So \(\frac{36}{3}\)=12
Each part is 12 so
boys is 12*2= 24 boys
Girls id 12*1= 12 girls
Answer:
12
Step-by-step explanation:
Total number of students in class ⇒ 36
Given that,
The number of boys is twice the number of girls.
First, let us make an expression to find the number of girls.
For that, let the number of girls be x.
Number of girls ⇒ x
Number of boys ⇒ 2x
Total number of pupils ⇒ x + 2x
So,
x + 2x = 36
3x = 36
Divide both sides by 3.
x = 12
Therefore, there are 12 girls and 24 boys in the class.

A. inequality that compares the temperatures of the two cities is: -2 > -6. B. inequality means city R, represented by -2 on the number line greater than the temperature of city S, represented by -6 on the number line. C. city R is warmer than city S.
Describe Inequality?In mathematics, an inequality is a statement that compares two values or expressions and indicates that one is greater than, less than, or equal to the other. Inequalities are used to describe relationships between values that are not necessarily equal, and they are written using special symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).
For example, the inequality 3x + 2 < 10 means that the expression 3x + 2 is less than 10. This inequality can be solved for x by subtracting 2 from both sides and then dividing by 3, yielding x < 2. This means that any value of x that is less than 2 will satisfy the inequality.
The inequality that compares the temperatures of the two cities is: -2 > -6
This inequality means that the temperature of city R, represented by -2 on the number line, is greater than the temperature of city S, represented by -6 on the number line. In other words, city R is warmer than city S.
On the number line, the further to the right a number is, the greater it is. Since -2 is to the right of -6, this indicates that -2 is greater than -6, which represents the fact that city R is warmer than city S.

On their most recent 8-mile training run, Pepe averaged a speed of 12 of a mile in 4.5 minutes, while Paula averaged 34 of a mile in 7.5 minutes.
How many minutes did it take the faster runner to finish the 8 mile run
Answer:
1.78 min
Step-by-step explanation:
so first you have to figure out the fastest runner
pepe 12 miles in 4.5 minutes
and paula ran 34 miles in 7.5 minutes
if you divide miles by minutes you get how many miles they ran in one minute
12/4.5=~2.67
34/7.5=~4.53
So you can see that paula is faster
if she ran ~4.5 miles in a minute then it would take her ~1.78 minutes to run 8 miles
they're both super humans though like woah
