Step-by-step explanation:
Would sorting the tiles with positive coefficients and tiles with negative coefficients together help to simplify an expression that involves all tiles? Explain.
Yes, it is possible to make an expression including all tiles simpler by grouping together the tiles with negative coefficients and the tiles with negative coefficients.
Negative coefficients: What are they?Simply put, negative coefficients are coefficients with negative values. A negative coefficient can be anything like -8 in the term -8z or -11 in the term -11xy. The result of multiplying the variables by the integer is negative.
What happens to a negative exponent's coefficient?A negative exponent signifies a very small number: The decimal in the coefficient is shifted eleven positions to the left as a result. A decimal number must also be moved in order to be expressed in scientific notation.

θ 0 pi over 6 pi over 3 pi over 2 2 pi over 3 5 pi over 6 π
r 4 2 −2 −4 −2 2 4
Which of the following graphs is represented by the table?
Answer:
r = 4 cos(2θ)
See the attached image for a graph.
Step-by-step explanation:
The points given by the table are in the graph of a cosine rose with 4 petals whose amplitudes are 4.
For the equation r = a cos(nθ), a is the amplitude of the petals (4), and n is half the number of petals, as there are an even number of petals (4/2 = 2).
Hence,
r = 4 cos(2θ)
Write a couple of paragraphs describing how you can determine the values of x that a) make
the rational function 0, and b) the values of x where the rational function is undefined:
f(x) = x²-2x+1
4x+5
The required paragraphs regarding with given expression f(x) = x²-2x+1/4x+5 have been explained later in the section.
A rational expression is a fraction in which the numerator and denominator are polynomials.
Here,
a) To determine the values of x that make the rational function f(x) equal to 0, we need to solve the equation:
x² - 2x + 1 = 0
Next, we can factor the quadratic on the left-hand side of the equation:
(x - 1)(x - 1) = 0
The quadratic is a perfect square, and we can see that it is equal to 0 when x = 1. So, the value of x that makes the rational function 0 is x = 1.
b) To determine the values of x where the rational function f(x) is undefined, we need to look for values of x that would make the denominator, 4x+5, equal to 0. If the denominator is equal to 0, then we would be dividing by 0, which is undefined.
So, we set the denominator equal to 0,
4x + 5 = 0
4x = -5
x = -5/4
Therefore, the value of x where the rational function is undefined is x = -5/4.

Write an equation for the function graphed
Answer:
y = |x - 3| - 1
Step-by-step explanation:
The vertex of the absolute value function graphed is (3, -1). The formula for absolute value is y = a |x - h| + k, where (h, k) is the vertex. The a stretches the graph, although this graph isn't stretched. So a is 1, which is the same as multiplying by 1. Plugging 3 as h and -1 as k into the formula results in y = |x - 3| - 1.

What is an absolute value inequality?
The non-negative value of a real number x without regard to its sign is known as its absolute value or modulus in mathematics and is indicated by the symbol |x|.
An expression using absolute functions and inequality signs is known as an absolute value inequality. One example of an absolute value inequality with a larger than symbol is the statement |x + 3| > 1.
1) length x = 4.2 cm with a tolerance of 0.01 cm
Absolute value inequality is:
|x - 4.2| ≤ 0.01
This can be written as:
x - 4.2 ≤ 0.01x ≤ 4.21
x - 4.2 ≥ - 0.01x ≥ 4.19
2) length x = 3.5 cm with a tolerance of 0.2 cm
Absolute value inequality is:
|x - 3.5| ≤ 0.2

If a truck carrying 3 tons of wheat unloads 1, 000 pounds, what is the weight of the
wheat still in the truck?
Answer: the weight of the wheat still in the truck is 5000 pounds.
Step-by-step explanation:
Here are the steps to calculate the weight of the wheat still in the truck:
Convert the weight of the unloaded wheat to tons. To convert from pounds to tons, divide by 2,000:
1000 lbs / 2000 lbs/ton = 0.5 tons
Subtract the weight of the unloaded wheat from the original weight:
3 tons - 0.5 tons = 2.5 tons
Convert the answer back to pounds:
2.5 tons * 2000 lbs/ton = 5000 lbs
Therefore, the weight of the wheat still in the truck is 5000 pounds.

The wheel of a car has an outer radius of 25 cm. Calculate: a how far the car has travelled after one complete turn of the wheel, b how many times the wheel turns for a journey of 1 km.
Answer: a) 1.57 m .
b) 637.79 turns
Step-by-step explanation:
a) The circumference of the wheel can be used to determine how far the vehicle has travelled after making one full turn.
Circumference = 2πr = 50π
C = 157 cm
b)By dividing the entire distance traveled by the diameter of the wheel, we can determine how many times the wheel will turn over a ride of 1 km (1000 meters): 1000 m / 1.57 m = 637.79 turns.

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower
class limits, and the upper class limits.
minimum = 10, maximum = 68, 7 classes
The class width is ?
The lower class limits are ?
The upper class limits are ?
Answer:
Step-by-step explanation:
213232131123123123123123
1. To find the class width, we first need to find the range of the data, which is the difference between the maximum and minimum values: 68 - 10 = 58. Then, we divide the range by the number of classes to get the class width: 58 / 7 = 8.29. However, we will round up to the nearest whole number, so the class width is 9.
2. The lower class limits are 10, 19, 28, 37, 46, 55, and 64, since we add the class width to the lower limit of each previous class to find the lower limit of the next class.
3. The upper class limits are 18, 27, 36, 45, 54, 63, and 68, since we add the class width to the lower limit of each class to find the upper limit of that class.
