Answer:
Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.
Step-by-step explanation:
The points given are (-4.5,0) and (3,0), which means the points are on the x-axis. Point R (-4.5,0) will be located to the left of 0, the negative side of the number line between the 4th and 5th marks. Point T (3,0) will be located to the right of 0, the positive side of the number line at the 3rd mark.
The second answer is incorrect because point (-4.5,0) is not on the right side of 0 but on the left side.
The third answer is incorrect because point T(3,0) is place between 2 and first mark instead of the third mark.
The fourth answer is incorrect because R (-4.5,0) is placed on the first mark instead of between 4th and 5th mark.

Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A point labeled R is placed between the 4th and 5th tick marks to the left of 0. A point labeled T is placed on the 3rd tick mark to the right of 0.

Answer:
the answer is c your welcome
The graph represents following situation: Gary initially has 40 stamps. He collects 5 stamps every week.
The correct answer is an option (C)
What is rate of change?"It describes how one quantity changes in relation to another quantity."
What is graph?"It is a set of points (x, y) that follows certain rule."
For given question,
We have been given a graph.
x represents the number of weeks since Gary starts tracking and y represents the total number of stamps in Gary's collection.
From the graph we can observe that initially he has 40 stamps.
We need to rate of stamp collection.
From the graph, the points (4, 60) and (8, 80) lie on the graph.
So, the rate of change would be,
\(\frac{80-60}{8-4}=5\)
This means, he collects 5 stamps every week.
Therefore, the graph represents following situation: Gary initially has 40 stamps. He collects 5 stamps every week.

Use Pascal's Triangle to expand (x^2-3y)^4
Answer
The expanded form of (x²-3y)⁴ using Pascal's Triangle is x⁸ - 12x⁶y² + 54x⁴y⁴ - 108x²y⁶ + 81y⁸.
What is Pascal's triangle?Pascal's Triangle is a triangular array of numbers in which the value in each cell is the sum of the two numbers directly above it.
To expand the given expression (x²-3y)⁴ as per Pascal's triangle:
First, write down the fourth row of Pascal's Triangle as:
1 4 6 4 1
The above numbers represent the coefficients of the terms in the expansion of (a+b)⁴, where a is x² and b is -3y. Therefore, it can be written as,
1×(x²)⁴ + 4×(x²)³×(-3y) + 6×(x²)²×(-3y)² + 4×(x²)(-3y)³ + 1(-3y)⁴
Simplify each term,
x⁸ - 12x⁶y² + 54x⁴y⁴ - 108x²y⁶ + 81y⁸
Therefore, the expanded form of (x²-3y)⁴ using Pascal's Triangle is x⁸ - 12x⁶y² + 54x⁴y⁴ - 108x²y⁶ + 81y⁸.

Solve for x assume that lines which appear to be diameters are actual diameters
The value of x in the circle that shows diameter is calculated as:
x = -7
What is the Diameter of a Circle?In a circle, the line segment that divides the circle into two halves is the diameter. Half of the circle is a semicircle which has a measure of 180 degrees.
Note: The measure of a central angle is also the same measure with that of the arc it intercepts.

-8x + 124 = 180
-8x = 180 - 124
-8x = 56

Using a system of equations, the rental cost for a movie and a video game is as follows:
Movie = $1.50Video game = $5.50.What is a system of equations?A system of equations is two or more equations solved concurrently or at the same time.
A system of equations is also described as simultaneous equations.
Movies Video Total
Games Cost
First month rental 3 5 $32
Second month rental 12 2 $29
Let the rental cost per movie = x
Let the rental cost per video game = y
Equations:
3x + 5y = 32 ... Equation 1
12x + 2y = 29 ... Equation 2
Multiply Equation 1 by 4:
12x + 20y = 128 ... Equation 3
Subtract Equation 2 from Equation 3:
12x + 20y = 128
-
12x + 2y = 29
18y = 99
y = 5.5
Substitute y = 5.5 in Equation 1 or 2:
12x + 2y = 29
12x + 2(5.5) = 29
12x + 11 = 29
12x = 18

If we divide 300 into parts using the ratio 2:3:5, we get:
2 parts = 2/10 of the total ratio = 2/10 x 300 = 60
3 parts = 3/10 of the total ratio = 3/10 x 300 = 90
5 parts = 5/10 of the total ratio = 5/10 x 300 = 150

For f(x) = √(x+4) , what is the value of the function when x = 8 ? Round to the nearest hundredth.
NEED ANSWER ASAP!!
Answer:
exact form : 2√3
decimal form : 3.46410161… or 3.46
hope this helps you!
Answer:
The value of the function is \(\sqrt{12}\). Rounded to the nearest hundredth, the answer is 3.46
Step-by-step explanation:
We are given the value of x, so we simply have to evaluate the function:
\(f(x)=\sqrt{x+4}\)
Substitute 8
\(f(8)=\sqrt{8+4}\)
Add in the radical
\(\sqrt{12}\)
The value of the function is sqrt(12).
Rounded to the nearest hundredth: \(3.46\)
6x^2=-3x+1 to the nearest hundredth
The solutions to the quadratic equation 6x² = -3x + 1 to the nearest hundredth are -0.73 and 0.23.
What are the solutions to the quadratic equation?Given the quadratic equation in the question:
6x² = -3x + 1
To solve the quadratic equation 6x² = -3x + 1, we can rearrange it into standard form, where one side is set to zero:
6x² + 3x - 1 = 0
Now we can solve the equation using the quadratic formula, which states that for an equation in the form ax² + bx + c = 0, the solutions for x are given by:
\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\)
Here; a = 6, b = 3, and c = -1.
Let's substitute these values into the quadratic formula:
\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\\\\ x= \frac{-3 \±\sqrt{3^2-4\ *\ 6\ *\ -1} }{2*6}\\\\x = \frac{-3 \±\sqrt{9+24} }{12}\\\\x = \frac{-3 \±\sqrt{33} }{12}\\\\x = -0.73, \ x=0.23\)
Therefore, the values of x are -0.73 and 0.23.

Do you take the free samples offered in super- markets? About 70% of all customers will take free samples. Furthermore, of those who take the free samples, about 30% will buy what they have sampled. Suppose you set up a counter in a supermarket offering free samples of a new product. The day you are offering free samples, 317 customers pass by your counter.
Answer:
222 customers took a free sample of the product, and 67 finally bought it.
Step-by-step explanation:
Given that 317 consumers passed through the sample stand, and taking into account that 70% usually take free samples, the number of people who take free samples is determined by the following calculation:
317 x 70/100 = X
22,190 / 100 = X
221.9 = X
Therefore, of the 317 consumers, about 222 took free samples of the product. Furthermore, of those 222, it is estimated that 30% bought the product after testing the sample. To determine the number of people who bought the product, the following calculation must be made:
222 x 30/100 = X
6,660 / 100 = X
66.6 = X
Therefore, 67 consumers purchased the product after taking a free sample of it.
Find the perimeter of the regular polygon ?
The perimeter of the regular polygon is 232
How to find the perimeter of the regular polygon?The side lengths of the regular polygon are given as
4/3x - 1/3 and x + 7
The sides of regular polygon are equal
So, we have:
4/3x - 1/3 = x + 7
Multiply both sides by 3
4x - 1 = 3x + 21
Collect like terms
4x - 3x = 1 + 21
Evaluate the like terms
x = 22
Substitute x = 22 in x + 7
Side = 22 + 7
Side = 29
The perimeter of the regular polygon is calculated as:
Perimeter = Number of sides x Side length
So, we have
Perimeter = 8 * 29
Evaluate
Perimeter = 232

SetupLet w represent the width of the field. Then (3w-120) is the length of the field, and its perimeter is ...
P = 2(L +W)
1040 = 2((3w-120) +w)
