EXPLAIN what equivalent fractions are and give an example. PLEASE answer me.
Answer: Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same.
Step-by-step explanation : For example, think about the fraction 1/2. It means half of something. You can also say that 6/12 is half, and that 50/100 is half. They represent the same part of the whole. These equivalent fractions contain different numbers but they mean the same thing: 1/2 = 6/12 = 50/100
Multiply both the numerator and denominator of a fraction by the same whole number. As long as you multiply both top and bottom of the fraction by the same number, you won't change the value of the fraction, and you'll create an equivalent fraction.

Graph f(x)=(x−2)(x−6) .
Use the parabola tool then choose the vertex followed by one point on the parabola.
Here is the graph for the equation
Given function to be graphed is,
f(x) = (x - 2)(x - 6)
We will convert the equation of the function into the vertex form,
(x - 2)(x - 6) = x(x - 6) - 2(x - 6)
= x² - 6x - 2x + 12
= x² - 8x + 12
= x² - 2(4x) + 16 - 4
f(x) = (x - 4)²- 4
By comparing this equation with the vertex form of the equation of a parabola,
g(x) = a(x - h)² + k
Here, (h, k) is the vertex of the parabola.
Therefore, vertex of the function 'f' will be (4, 4).
Now we will find the x-intercepts and y-intercept of the function.
For x-intercept, put f(x) = 0
0 = (x - 4)²- 4
(x - 4) = ±2
x = 4 ± 2
x = 2, 6
Therefore, x-intercepts of the function are (2, 0) and (6, 0).
For y-intercept, put x = 0
f(0) = (0 - 2)(0 - 6)
f(0) = 12
Therefore, y-intercept of the function is (0, 12).
By plotting these ordered pairs and joining them by a curve we can get the graph of the parabola.

The factored forms are [tex]\((p + 4c)(p - 4c - 1)\)[/tex] for the first expression and [tex]\(-(x - 7)(y - 7)\)[/tex] for the second expression.
Let's factor the given expressions:
1. [tex]\(p^2 - 16c^2 - p - 4c\)[/tex]:
To factor this quadratic expression, we can use the difference of squares formula, [tex]\(a^2 - b^2 = (a + b)(a - b)\)[/tex]. In this case, [tex]\(p^2 - 16c^2\)[/tex] is a difference of squares, so we can factor it as [tex]\((p + 4c)(p - 4c)\)[/tex]. The remaining terms are [tex]\( - p - 4c\)[/tex], and thus, the factored form is [tex]\((p + 4c)(p - 4c) - (p + 4c)\)[/tex]. Factoring out the common factor of -1 from the last two terms gives us the final factored expression: [tex]\((p + 4c)(p - 4c - 1)\)[/tex].
2. [tex]\(x^2 - 7x + 7y - y^2\)[/tex]:
This expression is a quadratic trinomial, and to factor it, we need to find two binomials whose product equals the given expression. The expression can be rewritten as [tex]\(x^2 - 7x - y^2 + 7y\)[/tex]. Now, we can group the terms as [tex]\((x^2 - 7x) - (y^2 - 7y)\)[/tex]. Factoring out \(x\) from the first group and y from the second group, we get [tex]\(x(x - 7) - y(y - 7)\)[/tex]. Now, we notice that both terms have a common factor of -1, so we can factor that out to obtain the final result: [tex]\(-(x - 7)(y - 7)\)[/tex].
I need the answer to y=2x+7 in a graph and passes through (3,3)
I need the given, parallel, slope intercept form
The slope-intercept form is y = 2x-3.
Step-by-step explanation:
Given,
The equation of the line is y=2x+7.The general equation of the line is in the form y= mx+c.where 'm' represents the slope of the line.Comparing the given equation with general equation, it can be determined that :
m = 2 and c = 7 (y-intercept).

Given that Z = X m W = 4x + 20 and m Y = x + 26 find the value of x for which WXYZ must be a parallelogram
To find the value of x for which WXYZ must be a parallelogram, set up an equation by equating the lengths of opposite sides. Solve the equation to find the value of x.
Explanation:To find the value of x for which WXYZ must be a parallelogram, we first need to understand the properties of parallelograms. One important property is that opposite sides are equal in length. Given that WZ = XY, we can set up an equation: 4x + 20 = x + 26. By solving this equation, we can find the value of x.
4x + 20 = x + 26
Subtracting x from both sides, we get:
3x + 20 = 26
Subtracting 20 from both sides, we get:
3x = 6

A city has a population of 300000 people. Suppose that each year the population grows by 8.5%. What will the population be after 15 years? Use the calculator provided round your answer to the nearest whole number.
Answer:
682,500 people
Step-by-step explanation:
so just find how many people per year it grows by then add that number 15 times to 300,000
so 8.5% of 300,000 is 25,500 people
now multiply that by 15 to get 382,500
add that to 300,000
Final answer:
Using the exponential growth formula, the population of a city with an initial population of 300,000 and an annual growth rate of 8.5% will be approximately 962,100 after 15 years.
Explanation:
To calculate the future population of a city with an initial population of 300,000 people and an annual growth rate of 8.5% over 15 years, we use the formula for exponential growth:
P = P_0 (1 + r)[tex]^{t}[/tex]
where:
P is the future population,
P_0 is the initial population (300,000),
r is the annual growth rate (expressed as a decimal, so 8.5% becomes 0.085), and
t is the number of years (15).
Substituting the values we get:
P = 300,000 (1 + 0.085)¹⁵
Calculating this, we find:
P = 300,000 (1.085)¹⁵
P = 300,000 (3.207)
P ≈ 962,100
Therefore, after 15 years, the population is expected to be approximately 962,100, rounding to the nearest whole number.
Each side of a square is increasing at a rate of 8 cm/s. At what rate is the area of the square increasing when the area of the square is 25 cm2?
Answer:
80cm^2/s
Step-by-step explanation:
This is a related rates problem where we are considering the rate at which the area of a square changes with respect to time.
So lets consider the area of a square:
A = s^2 (where s represents the length of one side of the square)
Related rates problem deal with functions of time so if we take the area and side length as a function of time and then differentiate implicitly we get:
[tex]\frac{dA}{dt} = 2s(\frac{ds}{dt})[/tex]
The problem states that the side of a square is increasing at a rate off 8cm/s so we can conclude that ds/dt = 8cm/s leaving us with:
[tex]\frac{dA}{dt} = 16s[/tex]
Now, to solve for s we have to consider the other value given. If the area of the square is initially 25cm^2 we can plug this into our formula for area to solve for the side length.
25 = s^2
s = +/- 5 (since side lengths are only positive we only consider +5)
s = 5
Now we can plug this back in for s:
[tex]\frac{dA}{dt} = 80[/tex]
Therefore, the rate at which the area of the square is increasing is 80cm^2 per second.

1. A firefighter is called to rescue a cat caught in a tree. If the firefighter is standing 30
m from the base of the tree and if the angle to the cat is 20'. How high in the tree is
the cat?
Answer:
10.92m
Step-by-step explanation:
See attached picture for more illustration
Using SOH CAH TOA,
Tan 20° = opposite / adjacent
Tan 20° = x / 30
x = 30 * tan20
x = 10.919m = 10.92m
The height of the tree is 10.92m
Final answer:
The height of the cat in the tree is 10.44m
Explanation:
The question involves finding the height of a cat caught in a tree using trigonometry, specifically the tangent function. If the firefighter is standing 30m from the base of the tree and the angle to the cat is 20 minutes (which should be converted to degrees for typical trigonometric calculations), we can calculate the height of the cat in the tree. First, we need to convert the angle from minutes to degrees. Since 1 degree = 60 minutes, 20 minutes is equal to 20/60 degrees or approximately 0.33 degrees.
To find the height of the cat, we can use the tangent function (tan) in trigonometry, which is the ratio of the opposite side (the height of the cat in the tree, which we're trying to find) to the adjacent side (the distance from the firefighter to the base of the tree). Thus, the formula becomes height = tan(angle) × distance.
Using the formula:
distance = 30m
angle = 0.33 degrees
height = tan(0.33 degrees) × 30
Tan(20') x Distance
Calculating: Height = Tan(20') x 30m = 10.44m
The cuboid ABCDEFGH has sides AB = 3 cm, BC = 4 cm and CG = 5 cm.
What is the length AG? Give your answer in cm correct to 3 significant figures.
Answer:
7.071 cm
Step-by-step explanation:
Final answer:
To find the length AG in the cuboid ABCDEFGH, use the three-dimensional Pythagorean theorem twice. First finding the diagonal AC (which is equal to 5 cm), and then using it to find AG. The length AG, to three significant figures, is approximately 7.07 cm.
Explanation:
The length AG of a cuboid ABCDEFGH can be found by using the Pythagorean theorem in three dimensions. This theorem is an extension of the traditional Pythagorean theorem used in two dimensions. For the given cuboid, we start by using the Pythagorean theorem on triangle ABC to find the diagonal AC. The formula for the Pythagorean theorem is:
c2 = a2 + b2
Where c is the diagonal and a and b are the sides of the right triangle:
AC2 = AB2 + BC2
Plugging in the given values, we have:
AC2 = 32 + 42 = 9 + 16 = 25
So, AC = 5 cm.
Now, to find AG, we use the diagonal AC and side CG in another application of the Pythagorean theorem for the right triangle ACG:
AG2 = AC2 + CG2
AG2 = 52 + 52 = 25 + 25 = 50
AG = √50 ≈ 7.071 approximately.
Therefore, the length AG, expressed to three significant figures, is approximately 7.07 cm.
In a 45-45-90 triangle, the ratio of the length of the hypotenuse to the length of a side is
See the figure below for a better understanding of the problem. Since we have a 45-45-90 triangle, this is an isosceles triangle, so both the adjacent and opposite sides measure the same value, say, x. Then the hypotenuse would be:
[tex]H=\sqrt{x^2+x^2} \\ \\ H=2\sqrt{2}[/tex]
Then. the ratio of the length of the hypotenuse to the length of a side is:
[tex]\boxed{r=\frac{2\sqrt{x}}{x}}[/tex]
In a 45-45-90 triangle, the ratio of the length of the hypotenuse to the length of a side is √2:1. This means that if one of the legs (the sides opposite the 45-degree angles) has a length of "x" units, then the hypotenuse (the side opposite the 90-degree angle) will have a length of "x√2" units.
