The greatest common factor of 6s³t⁴ + 12s⁴t² - 15s²t³ is 3s²t², and the factored expression is 3s²t²(2st² + 4s² - 5t).

The greatest positive integer that divides two or more numbers without leaving a residual is known as the greatest common factor (GCF). In other words, the greatest number that is a factor of both (or all) of the specified numbers is chosen.

To identify the greatest common factor of 6s³t⁴ + 12s⁴t² - 15s²t³, we need to look for the largest expression that divides evenly into each term.

First, we can factor out the greatest common factor of the coefficients, which is 3: 3(2s³t⁴ + 4s⁴t² - 5s²t³)

Next, we can look for the greatest common factor of the variables. We can see that s²t² divides into each term: 3s²t²(2st² + 4s² - 5t)

Therefore, the greatest common factor of 6s³t⁴ + 12s⁴t² - 15s²t³ is 3s²t², and the factored expression is 3s²t²(2st² + 4s² - 5t).

1 ) Finding the difference 4/9 - ⅖:

We require a common denominator to subtract fractions. The least frequent multiple of 9 and 5 in this example is 45. So we'll recast both fractions with 45 as the denominator:

[tex]\frac{4}{9} = \frac{20}{45} \\\frac{2}{5} = \frac{18}{45}[/tex]

Now we can subtract:

[tex]\frac{20}{45} - \frac{18}{45} = \frac{2}{45}[/tex]

Therefore, the difference between 4/9 and ⅖ is 2/45.

Examine the prime factors of the denominator when the fraction is in its simplest elementary form to determine if it will have a terminating or repeating decimal. The decimal will end if they are made up of 2s and/or 5s.

2) calculating the quotient 2/9 / ⅚:

Fractions are divided by multiplying the first fraction by the reciprocal of the second fraction. So:

2/9 ÷ ⅚ = 2/9 x 6/5

Before multiplying, we can simplify:

2/9 x 6/5 = 12/45

And here's another example:

12/45 = 4/15

As a result, the quotient of 2/9 56 is 4/15.

3) Writing each terminating decimal as an integer quotient:

(a) 0.437 = 437/1000

(b) 8.2 = 82/10 = 41/5

Answer:

50 pages are filled with stamps.

Step-by-step explanation:

If 50% of the album is empty, then 50% of the album is filled with stamps.

So, the total number of stamps that the album holds is 500, and half of that (50%) is filled with stamps, which is:

500 * 50% = 250 stamps

Each page holds 5 stamps, so the number of pages filled with stamps is:

250 stamps / 5 stamps per page = 50 pages

For Bob: Mean =10.13,MAD = 2.66,Median =10.5 ,IQR = 5.5,Q1 = 8,Q3 = 13.5

for alan :Mean =7.25,Median = 7.5,IQR = 10,Q1 = 4,Q3 = 14

For Bob:

Mean = (8+15+10+10+10+15+7+8+10+9+12+11+11+13+7+8+9+9+8+10+11+14+11+10+9+12+14+14+12+13+5+13+9+11+12+13+10+8+7+8) / 38 = 10.13

MAD = 2.66 (calculated using the median of Bob's data)

To calculate the median and quartiles for Bob's data, we need to first sort the data in ascending order:

5, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11, 12, 12, 13, 13, 13, 14, 14, 15, 15

Median = (10+11) / 2 = 10.5

Q1 = median of the first half of the data = (8+8) / 2 = 8

Q3 = median of the second half of the data = (13+14) / 2 = 13.5

IQR = Q3 - Q1 = 13.5 - 8 = 5.5

Therefore, for Bob:

Median = 10.5

IQR = 5.5

Q1 = 8

Q3 = 13.5

For Alan:

Mean = (2+3+4+5+7+10+12+14+15+16) / 10 = 7.25

MAD = 2.81 (calculated using the median of Alan's data)

Median = 7.5 (calculated as the average of the 5th and 6th value in Alan's sorted data)

Q1 = 4

Q3 = 14

IQR = Q3 - Q1 = 14 - 4 = 10

Therefore, for Alan:

Median = 7.5

IQR = 10

Q1 = 4

Q3 = 14

To determine if there are any outliers, we can use the following formula:

Outliers = data points outside the range [Q1 - 1.5(IQR), Q3 + 1.5(IQR)]

For Bob:

Lower outlier bound = 8 - 1.5(5.5) = -0.25

Upper outlier bound = 13.5 + 1.5(5.5) = 24.25

There are no outliers in Bob's data.

For Alan:

Lower outlier bound = 4 - 1.5(10) = -11

Upper outlier bound = 14 + 1.5(10) = 29

There are no outliers in Alan's data.

If the team needs a more consistent player with a higher median and narrower IQR, Bob might be a better choice. On the other hand, if the team needs a player who can potentially score more points, Alan might be a better choice as his mean is higher.

The height of the box must be at least 2.9111 feet.

The volume of the cylinder is given by the formula V = πr²h, where r is the radius of the cylinder and h is its height.

Since the width of the cylinder is 3 feet, the radius is 1.5 feet.

The volume of the oil is 15 gallons, which is equivalent to 0.2 cubic feet. We know that this volume of oil takes up 75% of the space between the cylinder and the box, so the total space between the cylinder and the box is 0.2 / 0.75 = 0.2667 cubic feet.

Since the cylinder fits perfectly inside the box, the volume of the box is equal to the volume of the cylinder plus the space between the cylinder and the box. Therefore, we have:

Volume of box = Volume of cylinder + Volume of oil

Volume of box  = πr²h + 0.2667

Substituting the values we have:

Volume of box = π(1.5)²h + 0.2667

Volume of box = 7.0686h + 0.2667

To find the height of the box, we need to isolate h. We know that the volume of the box must be greater than or equal to the volume of the cylinder, so we can set up the inequality:

Volume of box  ≥ Volume of cylinder

πr²h + 0.2667 ≥ πr²(3)

h + 0.0889 ≥ 3

h ≥ 2.9111

Therefore, the height of the box must be at least 2.9111 feet.

If the federal reserve sets the reserve rate to %4, the resulting money multiplier is 25.

The link between the quantity of reserves kept by banks and the amount of money that may be generated through the practise of fractional reserve banking is known as the "money multiplier" in economics and finance. Under a system known as fractional reserve banking, banks are only obligated to maintain a portion of their deposits as reserves and are free to lend the remainder to borrowers.

The reserve ratio, or the percentage of deposits that banks must retain in reserves, is used to compute the money multiplier.

The money multiplier is determined using the formula:

Money multiplier = 1 / reserve ratio

Given the reserve ratio is 4% = 0.04.

Thus,

Money multiplier = 1 / 0.04 = 25

Hence, if the federal reserve sets the reserve rate to %4, the resulting money multiplier is 25.

Answer:

Step-by-step explanation:

The given sequence can be written as:

a_1 = 8

a_2 = 10

a_3 = 12.5

a_4 = 15.625

To find the recursive formula, we need to find the common ratio (r) between consecutive terms:

r = a_2 / a_1 = 10 / 8 = 1.25

r = a_3 / a_2 = 12.5 / 10 = 1.25

r = a_4 / a_3 = 15.625 / 12.5 = 1.25

Since the common ratio is constant, we can use the formula for a geometric sequence to find the recursive formula:

a_n = r * a_{n-1}

Substituting r = 1.25 and a_1 = 8, we get:

a_n = 1.25 * a_{n-1}

Therefore, the recursive formula for the given sequence is:

a_n = 1.25 * a_{n-1}, with a_1 = 8.

The density of gold is given as 5×2^2 grams/cm³, which means that one cubic centimeter of gold has a mass of 5×2^2 grams.

To find the mass of 8 × 25 cm³ of gold, we need to first find the total volume of gold:

Total volume = 8 × 25 cm³ = 200 cm³

Now we can use the density of gold to find the mass:

Mass = Density × Volume

Mass = (5×2^2 grams/cm³) × 200 cm³

Mass = 5 × 4 × 200 grams

Mass = 4000 grams

Therefore, the mass of 8 × 25 cm³ of gold is 4000 grams.

The given sequence is an arithmetic sequence with a common difference of 3. To find the value of n for the number 14 in the sequence, we can use the explicit formula for an arithmetic sequence:

a_n = a_1 + (n-1)d

where a_n is the nth term of the sequence, a_1 is the first term, d is the common difference, and n is the term number.

Substituting the given values, we get:

14 = 2 + (n-1)3

Simplifying the equation, we get:

12 = 3n - 3

15 = 3n

n = 5

Therefore, the number 14 appears as the 5th term in the sequence.

To find the sum of the sequence, we can use the arithmetic sum formula:

S_n = (n/2)(a_1 + a_n)

where S_n is the sum of the first n terms of the sequence.

The x-coordinate (or t-coordinate) of the vertex is 1.5 seconds and represents the time at which the rocket reaches its maximum height. The y-coordinate (or h-coordinate) of the vertex is 334 feet and represents the maximum height reached by the rocket.

A function is a mathematical relationship that describes how one quantity (the output or dependent variable) depends on one or more other quantities (the inputs or independent variables).

A function can be thought of as a machine that takes in input values, applies a set of rules or operations to them, and produces an output value. The input values can be any set of numbers or other objects that the function is defined for, and the output values can be any set of numbers or objects that the function can produce.

To find the x-coordinate (or t-coordinate) of the vertex, we can use the formula:

x = -b / (2a)

where a is the coefficient of the squared term, b is the coefficient of the linear term, and x represents the time at which the rocket reaches its maximum height. The equation of the parabolic function that models the height of the rocket is:

h = at² + bt + c

where h is the height of the rocket at time t.

We can use the coordinates of the points on the parabola to find the values of a, b, and c:

(0, 260): 260 = a(0)² + b(0) + c, so c = 260

(2, 324): 324 = a(2)² + b(2) + 260, so 4a + 2b = 64

(6.5, 0): 0 = a(6.5)² + b(6.5) + 260, so 42.25a + 6.5b = -260

We can solve this system of equations to find the values of a and b:

4a + 2b = 64

42.25a + 6.5b = -260

Multiplying the first equation by 3.25 and subtracting from the second equation, we get:

42.25a + 6.5b - 13a - 6.5b = -260 - 208

29.25a = -468

a = -16

Substituting a = -16 into the first equation, we get:

4(-16) + 2b = 64

b = 48

Therefore, the equation of the parabolic function is:

h = -16t² + 48t + 260

The x-coordinate (or t-coordinate) of the vertex is:

t = -b / (2a) = -48 / (2(-16)) = 1.5

The x-coordinate (or t-coordinate) of the vertex is 1.5 seconds and represents the time at which the rocket reaches its maximum height.

To find the y-coordinate (or h-coordinate) of the vertex, we can substitute t = 1.5 into the equation of the parabolic function:

h = -16(1.5)² + 48(1.5) + 260 = 334

Therefore, the y-coordinate (or h-coordinate) of the vertex is 334 feet and represents the maximum height reached by the rocket.

No. The function is nonlinear and its slope is not constant.

A linear function can be written in this form, y = a + bx.

In this function, b is the slope of the line. The slope describes the constant unit of change in x, the independent variable, that will result in a change in y by the amount of b.

The slope can be determined as the change in y/change in x or rise/run.

In a nonlinear function, the slope does not produce a constant unit of change in that results in a change in y by the amount of b.

The correct inequality that represents the statement "One half of a number decreased by 3 is at most -5" is option C) x ≤ -4.

What is an inequality?

Let's start by defining a variable for the number we are trying to find. Let's call it "x".

"One half of a number" can be represented as (1/2)x.

"Decreased by 3" means we need to subtract 3 from (1/2)x. So, "one half of a number decreased by 3" can be represented as:

(1/2)x - 3

Now, the problem says that this expression is "at most -5". "At most" means that the expression can be equal to -5 or any number less than -5. We can represent this as:

(1/2)x - 3 ≤ -5

To simplify this inequality, let's add 3 to both sides:

(1/2)x ≤ -2

Multiplying both sides by 2 (to eliminate the fraction) gives:

x ≤ -4

The line of tangency at the point (–6, 3) is x = -6. So, the correct option is (b).

What is tangent?

In geometry, the tangent is a trigonometric function that relates to the angles and sides of a right triangle. Specifically, the tangent of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the adjacent side.

To find the line of tangency to a circle at a given point, we need to first find the slope of the radius that passes through that point, and then take the negative reciprocal of that slope to get the slope of the tangent line.

Given the circle equation: (x + 2)² + (y - 3)²  = 16, we can see that its center is at the point (-2, 3) and its radius is 4.

To find the slope of the radius passing through the point (-6, 3), we can use the point-slope formula:

(y - y1) = m(x - x1)

where m is the slope of the radius, and (x1, y1) is the center of the circle (-2, 3). Plugging in the values, we get:

(y - 3) = m(x + 2)

Substituting the point (-6, 3) into the equation, we get:

(3 - 3) = m((-6) + 2)

0 = -4m

m = 0

So the slope of the radius is 0. To find the slope of the tangent line, we take the negative reciprocal of the slope of the radius:

slope of tangent line = -1/0 = undefined

Since the slope of the tangent line is undefined, it must be a vertical line passing through the point (-6, 3). Thus, the line of tangency at the point (-6, 3) is the vertical line x = -6.

Derived from that, we can get m∠1 + m∠2 = 180°, which in other "words" is x + y = 180°.

Great, now we have our 2 equations, and we just have to solve.

Equations:

  1. y = 16° + 3x

  2. x + y = 180°

Let's substitute what we have for y into the second equation:

x + (16° + 3x) = 180°

Solve:

(We can take out parentheses because it's a "+" sign)

Combine like terms:

4x + 16° = 180°

Subtract 16° from both sides

4x = 164°

Isolate x by dividing both sides by 4

x = 41°

Substitute:

Now that we have x = 41°, we can substitute that in for the equation - "y = 16° + 3x"

New Equation:

y = 16° + 3(41°)

Solve:

Multiply 3 and 41°, which is 123°

y = 16° + 123°

Simplify:

y = 139°

Reminder:

m∠1 = x

m∠2 = y

Therefore,

m∠1 = 41°

&

m∠2 = 139°

Hopefully this helps!

Answer:

Basically, a straight line is equal to 180 degrees. If angle 2 is 16 more than 3 times angle 1, we get the equation of y = 16 + 3x. Put them together and you get x + 16 + 3x = 180. Then you just solve, and get x = 41. Then you put x in for the other equation and get y = 139.
