Classify is the function as increasing decreasing or constant l
f(x) = 5x
Anyone know the answer .?
Answer:
Increasing
Step-by-step explanation:
Remember that f(x) is the same as y in slope intercept form y = mx + b.
We don’t have a number for “b” which means the line goes across the origin.
Since 5 replaces m, that is the slope and since it’s positive, it is increasing.

List all possible rational roots for the given equation. x^4 - 2 x^2 + 16 x - 15 = 0
The possible roots for the given equation are, -1,3, -1-2i, -1+2i.
What do you mean by the roots of an equation?
The values of the variable that fulfill the equation are known as the roots of a quadratic equation. In addition, they are referred to as the "solutions" or "zeroes" of the quadratic equation. For instance, x = 2 and x = 5 satisfy the quadratic equation x2 - 7x + 10 = 0 and are hence the roots of the equation.
F(x) = x4-2x2-16x-15 has a root (zero) that you should find.
Finding x values for which F(x)=0 is the goal of the Polynomial Roots Calculator method set.
A tool from the list above is the rational roots test. Only numbers x that can be represented as the quotient of two integers, or rational roots, would be found.
According to the Rational Root Theorem, P and Q are factors of the Leading Coefficient and the Trailing Constant, respectively, if a polynomial zeroes for a rational number P/Q.

(-6,-3) and (-9,-2)
Write the equation of the line passing through the given points. Write the equation in standing form
Ax+By=C
The equation to the line is:
Answer:
x + 3y = -15
Step-by-step explanation:
There are 2 ways to find this equation:
The first way: We have: y = ax + b (this is the line, right?)
The line is through the point (-6, -3) so we have:
-3 = (-6)a + b (1)
The line is also through the point (-9, -2) so we have:
-2 = (-9)a + b. (2)
From (1) and (2) we get a equals -1/3, b equals -5. Then:
\(y=-\frac{1}{3} x - 5\)
<=> \(x + 3y=-15\)
The second way:
Let A(-6, -3) and B(-9, -2), then AB = (-3, 1).
=> The normal vector of this line is n = (1, 3).
The line that is through the points A(-6, -3) and B(-9, -2), and has the normal vector n=(1, 3) has the equation:
\(1(x+6) +3(y+3)=0\\x+3y +15=0\\x+3y=-15\)
Identify the angles of rotational symmetry for the figure.
The angle of rotational symmetry would be 45 degrees.
What is the angle of rotational symmetry?
The angle of rotational symmetry, also known as the order of rotational symmetry, is a measure of how many times an object can be rotated about a central point and still look the same. It is defined as the smallest angle, in degrees, that an object can be rotated and still appear identical to the original shape.
The given figure has 8 spikes,
so we can find out the angle of rotational symmetry by dividing the 360 by number of spikes
The angle of rotational symmetry = 360/8
= 45 degrees.
Hence, the angle of rotational symmetry would be 45 degrees.

Step-by-step explanation:
1a. 2x + y = 5 Solve for y in the first equation.
y = -2x + 5
1b. 2(-2x + 5) = 2x - 8
-4x + 10 = 2x - 8
-6x + 10 = -8
-6x = -18
1c. x = 3
2y = 2x - 8
2y = 2(3) - 8
2y = 6 - 8
2y = -2
y = -1
Check Use x = 3; y = -1
1d. 2x + y = 5 2y = 2x - 8
2(3) - 1 = 5 2(-1) = 2(3) - 8

The graph shows the distribution of the lengths (in seconds) of videos on a popular video-streaming site. The distribution is approximately Normal, with a mean of 264 seconds and a standard deviation of 75 seconds.
A graph titled Streaming Videos has length (seconds) on the x-axis, going from negative 36 to 564. The highest point of the curve is at 264.
What percentage of videos on the streaming site are between 264 and 489 seconds?
0.15%
49.85%
95%
99.7%
According to the properties of the standard normal distribution, approximately 99.7% of the values lie within three standard deviations of the mean. Therefore, the answer is 99.7%.
To determine the percentage of videos on the streaming site that are between 264 and 489 seconds, we need to calculate the area under the normal curve within that range. Since the distribution is approximately normal with a mean of 264 seconds and a standard deviation of 75 seconds, we can use the properties of the standard normal distribution to find the desired percentage.
First, we need to convert the values 264 and 489 to z-scores, which represent the number of standard deviations a particular value is away from the mean. The z-score formula is given by:
z = (x - μ) / σ
where x is the value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get:
z1 = (264 - 264) / 75 = 0
z2 = (489 - 264) / 75 = 3
Next, we can use a standard normal distribution table or a calculator to find the area under the curve between z = 0 and z = 3. The area represents the percentage of videos falling within that range. The answer is 99.7% .

Active Exploration: Children learn best through hands-on exploration and interactions with the physical world.
Vygotsky Sociocultural Theory 1. Zone of Proximal Development (ZPD): Learning takes place within the gap between a learner's actual developmental level and their potential level with guidance from a more knowledgeable other. 2. Social Interaction: Learning is facilitated through social interactions with peers and adults, such as cooperative learning and scaffolding. 3. Cultural Tools: The use of language, symbols, and cultural artifacts plays a central role in cognitive development and learning.
Bruner Constructivism 1. Scaffolding: Instruction should provide support and guidance tailored to the learner's current abilities to help them progress to higher levels of understanding. 2. Discovery Learning: Learners construct knowledge by actively exploring and discovering concepts and relationships on their own. 3. Spiral Curriculum: Learning is organized in a spiral manner, revisiting key concepts and building upon previous knowledge in a progressive and interconnected way.

The cost that a recycling company charges is directly proportional to the number of recycling bins collected. The cost is $33 for each bin.
A: Write a direct variation equation to represent the cost.
B: How many bins can a customer pay the company to collect the bins for $500? Write and solve the equation.
C: Suppose the customer plans to tip the recycling company $30, how many bins can the customer get removed for $500 now? Write and solve the equation.
a) The direct variation equation is y = 33x.
b) The customer can pay the company to collect 15 bins.
c) The customer can get approximately 16 bins (rounded to the nearest whole number) removed for $500 with a $30 tip included.
A) The direct variation equation to represent the cost would be y = kx, where y represents the cost, x represents the number of bins collected, and k is the constant of proportionality. In this case, since the cost is $33 for each bin collected, the value of k is 33. Therefore, the direct variation equation is y = 33x.
B) To find the number of bins a customer can pay the company to collect for $500, we can set the cost (y) equal to $500 and solve for x (the number of bins). Thus, we have:
y = 33x
500 = 33x
x = 500/33
x ≈ 15.15
Therefore, the customer can pay the company to collect 15 bins (rounded to the nearest whole number) for $500.
C) If the customer plans to tip the recycling company $30, the total cost would be $500 + $30 = $530. We can set the cost (y) equal to $530 and solve for x:
y = 33x + 30
530 = 33x + 30
