Answer:
In factored form: [tex]y=\sqrt{-\frac{1}{25}(2x-10)(2x+10)}[/tex]
In standard form: [tex]y=\sqrt{-\frac{4}{25}x^2+4}[/tex]
Step-by-step explanation:
Generally for these type of equations we want to get the term with "y" by it self (ignoring coefficients and any operations such as square root, etc...) so we want to get rid of the [tex]4x^2[/tex] from the left side which we can do by subtracting this from both sides to maintain equality and get rid of it on the left side.
[tex]25y^2=-4x^2+100[/tex]
One thing I want to note here is we can actually factor the right side which we generally want to do, we can rewrite it as: [tex]-(4x^2-100)[/tex] and from here we have a difference of squares: [tex]a^2-b^2=(a-b)(a+b)[/tex] so we can rewrite this as: [tex]-(2x-10)(2x+10)[/tex]
[tex]25y^2=-(2x-10)(2x+10)[/tex]
From here we divide both sides by 25:
[tex]y^2=-\frac{1}{25}(2x-10)(2x+10)[/tex]
Now from here to get rid of that square we do the inverse which is taking the square root:
[tex]y=\sqrt{-\frac{1}{25}(2x-10)(2x+10)}[/tex]
The reason factoring is useful in this case is we can now easily determine the domain of the function since inside the square root we have a quadratic which is opening down meaning it's only not negative between the zeroes (including the zeroes since they're... zero not negative) and this would be the domain of the graph. But if we wanted it to not be in factored form we would just put back what we had so we would have:
[tex]y=\sqrt{-\frac{1}{25}(4x^2-100)}[/tex]
then distribute the -1/25 to get:
[tex]y=\sqrt{-\frac{4}{25}x^2+4}[/tex]
decide whether each proposed multiplication or division of measurements is possible. if it is possible, write the result in the last column of the table.
1. The unit g/cm³ is valid. So, division of measurements is possible.
2. The unit mm is valid. So, division of measurements is possible.
3. The unit L² is not valid. So, multiplication of measurements is not possible.
What are measurement units?
The group of units used to quantify different physical quantities collectively known as the units of measurement. Since ancient times, we have measured these things using many units, including length, mass, volume, current, and temperature.
1. 63g/7cm³ = 9 g/cm³
The density of a substance indicates how dense it is in a given area. Mass per unit volume is the definition of a material's density. In essence, density is a measurement of how closely stuff is packed. It is a particular physical characteristic of a specific thing.
The unit g/cm³ is a unit for measuring density.
Therefore, the division of measurements is possible.
2. The m or mm must be converted so that the units are the same.
1 m = 1000 mm.
Convert the meters to mm:
0.080 m = 80 mm.
480 mm²/80 mm = 6 mm
The word "area" refers to a free space. A shape's length and width are used to compute its area. Unidimensional length is expressed in terms of feet (ft), yards (yd), inches (in), etc.
The mm² is a unit for measuring area.
The m is a unit for measuring length or width.
Therefore, the division of measurements is possible.
3. (4.5 dL) × (0.70 L)
Liquid volume is a term used to describe how much 3-D space a given amount of liquid takes up.
Volume of a liquid is measured in litres (L).
Squaring Litres doesn't make any sense.
Therefore, the multiplication of measurements is not possible.

Let L represent the number of workers hired by a firm, and let Q represent that firm's quantity of output. Assume two points on the firm's production function are (L = 12, Q = 122) and (L = 13, Q = 132). Then the marginal product of the 13th worker isa.) 8 units of output.b.) 10 units of output.c.) 122 units of output.d.) 132 units of output.
The amount of marginal product of the 13th worker is 10 units of output, which is the difference between the quantity of output when L = 12 (122) and when L = 13 (132).
The marginal product of the 13th worker can be calculated as follows:
Marginal product = Quantity of output for L = 13 - Quantity of output for L = 12
Marginal product = 132 - 122
Marginal product = 10 units of output
The marginal product of the 13th worker is the additional output created by hiring one additional worker. This is calculated by taking the difference between the quantity of output when the number of workers is 12 and when it is 13. In this case, the quantity of output when L = 12 is 122, and when L = 13 it is 132, so the marginal product is 10 units of output. This calculation shows that the 13th worker is adding 10 units of output to the firm's total production. This is an important concept in production economics, as it helps firms determine the optimal number of workers to hire in order to maximize their output and profits.

The volume of the ark is about 1.44 million cubic feet.
What is unit conversion mean?
A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
First, we need to convert the measurements from cubits to inches.
We know that one cubit is equal to six palms and that one palm is equal to 2.5 inches. So, we can convert the measurements of the ark by multiplying the number of cubits by the number of inches per cubit:
Length of ark = 300 cubits x 6 palms/cubit x 2.5 inches/palm = 4500 inches
Width of ark = 50 cubits x 6 palms/cubit x 2.5 inches/palm = 750 inches
Height of ark = 30 cubits x 6 palms/cubit x 2.5 inches/palm = 450 inches
Next, we can find the volume of the ark by multiplying these dimensions together:
Volume of ark = 4500 inches x 750 inches x 450 inches = 1.42 x 10^9 cubic inches
Finally, we can convert cubic inches to cubic feet by dividing by the conversion factor of 1 cubic foot = 12 x 12 x 12 cubic inches.
1.42 x 10^9 cubic inches / (12x12x12 cubic inches/cubic foot) = 1.44 x 10^6 cubic feet
Hence, the volume of the ark is about 1.44 million cubic feet.

AB multiplication of two matrices
multiplication of two matrices is possible only when B has the same number of columns as rows in A,
[tex]A_{m*n}[/tex]and [tex]B_{n*p}[/tex]
If it is defined as above, then the matrix AB will have m rows and p columns, i.e., A must have n columns and B must have n rows in order for AB to be defined.
[tex](AB)_{m*n}[/tex]
In addition, a matrix gets transposed when columns turn into rows and vice versa.

Fin volunteers at the local pet shelter with his friends Conor and Tiah. His friends each volunteer 1.5 hours longer than Fin. The three friends volunteer for a combined total of 12 hours. Let x represent the number of hours that Fin volunteers. Which is the equation that would answer this question?
x+ 2x +1.5 = 12
x+x+x+1.5 = 12
x+ 2(x+1.5) = 12
x+ (2x +1.5) = 12
The equation that would answer this question is x + (2x + 1.5) = 12. where x is the number of hours that Fin volunteers, and 2x + 1.5 represents the number of hours that each of his friends volunteers.
How to find the equation?In this scenario, you can set up an equation that represents the total amount of time Fin and his friends volunteer. Let 'x' be the number of Finn's volunteer hours. His friends volunteer 1.5 hours more than Finn, so the number of hours each friend volunteers can be represented by x + 1.5. The total number of hours that all three friends volunteered can be expressed as:
x + (x + 1.5) + (x + 1.5) = 12
Expansion of the 2nd and 3rd terms:
x + x + 1.5 + x + 1.5 = 12
Combining the same terms:
3x + 4.5 = 12
Subtract 4.5 from both sides:
3x = 7.5
Divide both sides by 3:
x = 2.5
So Fin volunteers his 2.5 hours.

The likelihood that a randomly selected youngster is under 49 inches tall is 0.989
The likelihood that a randomly selected child would be taller than 48.8 inches is 0.875.
Let the X represent a ten-year-old child's height measurements.
As a result, with a mean of 56.2 inches and a standard deviation of 3.3 inches, X follows the normal distribution.
A) We need to calculate the likelihood that a youngster selected at random is under 63.75 inches tall.
Specifically,
P(X < 63.75)
The Z score calculation gives us
Z = (X - μ)/σ
where mean is and standard deviation is.
Z = (63.75 - 56.2)/3.3
Z = 2.288 as a result.
According to the z distribution table, the value is around 0.989
B) Similar to this, the Z score formula gives us
Z = (X - μ)/σ
where μ mean is and σ standard deviation is.
Therefore, we must determine the likelihood that a child picked at random will be taller than 60 inches.
Z = (60 - 56.2)/3.3
Z = 1.1515

Find the 8th term of the sequence below.
Tn = 2n²-3n - 6
T8 =
Sorry again I don’t understand how to do this :(
Answer:
8th term = 98
Step-by-step explanation:
Given equation,
→ Tn = 2n² - 3n - 6
Now the 8th term will be,
→ Tn = 2n² - 3n - 6
→ T8 = 2(8)² - 3(8) - 6
→ T8 = 2(64) - 24 - 6
→ T8 = 128 - 30
→ [ T8 = 98 ]
Hence, the 8th term is 98.

4:5=___:35 fill in the missing value
Answer: 28:35
Step-by-step explanation: The missing number is 28, here's how to solve it:
So, if we know both components of the first ratio AND the second component of the 2nd ratio, we need to divide the 2nd components from each ratio. So, 35 / 5 = 7. Now, we need to multiply 7 by 4. We get 28. So, the 2nd ratio is 28:35. I hope this helps!

it is possible to have a function with an infinite number of critical points. also, it is possible to have a function where every point is a critical point. g
A function with an infinite number of critical points can be expressed as a continuous function with a derivative that is equal to zero at every point in its domain.
For example, the function f(x) = 0 has an infinite number of critical points since its derivative f'(x) = 0 for every x in its domain. Alternatively, a function that has every point as a critical point can be expressed as a function with a derivative that is always equal to zero. For example, the constant function f(x) = c has a derivative f'(x) = 0 for every x in its domain, and thus every point in its domain is a critical point.
In addition, an example of a function with every point as a critical point is the constant function, f(x) = c, where c is a constant. The derivative of this function is f'(x) = 0, which means that the derivative is zero for all values of x. Therefore, every point of the constant function is a critical point.

The types of words must be capitalized is
A) A government position when it comes before a specific name
What is Word Capitalization?In writing systems with a case distinction, capitalization (American English) or capitalisation (British English) refers to writing a word with its initial letter as a capital letter (uppercase letter) and the other characters in lower case. The phrase could also be used to describe the choice of text case.
Given:
In English, the initial word of a phrase and all proper nouns are written in capital letters (words that name a specific person, place, organization, or thing).
The initial word in a quotation and the first word following a colon may occasionally both need to be capitalized.
So, the types word can be capitalized is a government position when it comes before a specific name like President Obama.

A bird of species A, when diving, can travel 5 times as fast as a bird of species B top speed. If the total speeds for these two birds is 222 miles per hour, find the fastest speed of the bird of species A and the fastest speed of the bird of species B.
The fastest speed of the bird of species A is 185 mph and the fastest speed of the bird of species B is 37 mph
What is an equation?
An equation is an expression showing the relationship between numbers and variables.
Let a represent the top speed of bird A and b represent the top speed of bird B.
A bird of species A, when diving, can travel 5 times as fast as a bird of species B top speed, hence:
a = 5b
a - 5b = 0 (1)
If the total speeds for these two birds is 222 miles per hour, hence:
a + b = 222 (2)
To solve by elimination method, subtract equation 2 from 1, hence:
-6b = -222
Dividing by -6:
b = 37
Put b = 37 in equation 2:
a + 37 = 222
a = 185
The speed of the bird are 185 miles per hour and 37 miles per hour

Let S be a subset of R that is closed under multiplication (that is, if a and b are in S, then so is ab). Let Tand Ube disjoint subsets of S whose union is S .Given that the product of any three (not necessarily distinct) elements of T is in T and that the product of any three elements of U is in U, show that at least one of the two subsets T, U is closed under multiplication.
We start out with the assumption that neither T nor U is closed under multiplication and use proof by contradiction to prove that at least one of T or U must be closed under multiplication.
If t1, t2 ,t3 ∈T and u1 ,u2 , u3 ∈U, it is given by the problem that t1⋅t2⋅t3∈T
and u1⋅u2⋅u3∈U. Also, T and U are disjoint subsets of S and therefore, T∩U = ∅ Now let t3=u1⋅u2 and u3=t1⋅t2. These statements are valid because T and U are not closed under multiplication, so the product of u1⋅u2 must not be in the set U and the product of t1⋅t2 must not be in set T.
Then t1⋅t2⋅t3∈T is equivalent to t1⋅t2⋅u1⋅u2∈Tand u1⋅u2⋅u3∈U is equivalent to u1⋅u2⋅t1⋅t2∈U
However, this is a contradiction because these products both are the same —t1⋅t2⋅u1⋅u2— but T∩U= ∅ because Tand U are disjoint. Then the original assumption that "neither T nor U is closed under multiplication" must have been wrong, and at least one of T or U must be closed under multiplication.
