find the list number which is a perfect square and exactly divisible by 10,12and 15​

Answers

Answer 1

Answer:

The smallest perfect square that is exactly divisible by 10, 12, and 15 is 900.

Step-by-step explanation:

The explanation is:

A perfect square is a number that is the product of two equal integers. For example, 25 is a perfect square because it is 5 times 5.

A number that is exactly divisible by 10, 12, and 15 must have all the prime factors of these numbers in its prime factorization. The prime factors of 10 are 2 and 5, the prime factors of 12 are 2 and 3, and the prime factors of 15 are 3 and 5. Therefore, the number must have at least two 2s, one 3, and one 5 in its prime factorization.

To make the number a perfect square, each prime factor must appear an even number of times. Therefore, we need to add another 2, another 3, and another 5 to the prime factorization. The number becomes 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5, which is equal to 900.

We can check that 900 is a perfect square by finding its square root. The square root of 900 is 30, which is an integer. We can also check that it is exactly divisible by 10, 12, and 15 by dividing it by these numbers. The quotients are all integers: 90, 75, and 60 respectively.

If you were to roll a fair, six-sided die, what is the probability of getting a 3?

(A) 3/6
(B) 1/3
(C) 5/6
(D) 1/6

Answers

The probability of rolling a 3 is: Probability = 1/6. Option D

To determine the probability of rolling a 3 on a fair, six-sided die, we need to consider the total number of possible outcomes and the number of favorable outcomes.

A fair, six-sided die has six faces, numbered from 1 to 6. Each face has an equal chance of appearing when the die is rolled.

In this case, there is only one face with the number 3, so there is only one favorable outcome for rolling a 3.

The total number of possible outcomes when rolling the die is six, corresponding to the numbers 1 to 6 on the faces.

Therefore, the probability of rolling a 3 can be calculated as:

Probability = Number of favorable outcomes / Total number of possible outcomes

In this case, the number of favorable outcomes is 1 (rolling a 3), and the total number of possible outcomes is 6.

Thus, the probability of rolling a 3 is:

Probability = 1/6. Option D is correct.

Donnez l’intégral de -x+5/(x^2-4x+4)(x+1)

Answers

Answer:

[tex]\frac{2}{3}\ln(x+1)-\frac{1}{x-2} -\frac{2}{3}\ln(x-2)+C[/tex]

Step-by-step explanation:

Integrate the following expression.

[tex]\int \frac{-x+5}{(x^2-4x+4)(x+1)}[/tex]

[tex]\hrulefill[/tex]

In order to integrate this function we are gonna have to use partial fraction decomposition. Start by factoring the the denominator completely.

[tex]\int \frac{-x+5}{(x^2-4x+4)(x+1)}dx\\\\\Longrightarrow \int \frac{-x+5}{(x-2)^2(x+1)}dx[/tex]

Now we can apply partial fractions. Partial fractions allows us to split up complex fractions, in doing so this will make them easier to integrate.

[tex]\frac{-x+5}{(x-2)^2(x+1)}=\frac{A}{x+1}+\frac{B}{(x-2)^2}+\frac{C}{x-2}\\\\\Longrightarrow \frac{-x+5}{(x-2)^2(x+1)}=\frac{A}{x+1}+\frac{B}{(x-2)^2}+\frac{C}{x-2} \Big](x-2)^2(x+1)\\\\\Longrightarrow \boxed{-x+5=A(x-2)^2+B(x+1)+C(x-2)(x+1)}[/tex]

Expand the right-hand-side and use the comparison method to find the values of the undetermined coefficients, A, B, and C.

[tex]-x+5=A(x-2)^2+B(x+1)+C(x-2)(x+1)\\\\\Longrightarrow -x+5=Ax^2-4Ax+4A+Bx+B+Cx^2-Cx-2C\\\\\Longrightarrow \boxed{0x^2-x+5(1)=(A+C)x^2+(-4A+B-C)x+(4A+B-2C)(1)}[/tex]

We can now form a system of equations.

For x^2 terms:

[tex]A+C=0[/tex]

For x terms:

[tex]-4A+B-C=-1[/tex]

For #'s:

[tex]4A+B-2C=5[/tex]

[tex]\Longrightarrow \left\{\begin{array}{ccc}A+C=0\\-4A+B-C=-1\\4A+B-2C=5\end{array}\right[/tex]

You can use any method of choice to solve the system of equations. I am going to put the system in a matrix and use my calculator to row reduce.

[tex]\Longrightarrow \left[\begin{array}{ccc}1&0&1\\-4&1&-1\\4&1&-2\end{array}\right] =\left[\begin{array}{c}0\\-1\\5\end{array}\right]\\\\ \\ \ \ \ \Longrightarrow \left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right] =\left[\begin{array}{c}\frac{2}{3} \\1\\-\frac{2}{3}\end{array}\right]\\\\\\\therefore \boxed{A=\frac{2}{3}, \ B=1, \ \text{and} \ C=-\frac{2}{3}}[/tex]

Now we can split up the fraction.

[tex]\frac{-x+5}{(x-2)^2(x+1)}=\frac{A}{x+1}+\frac{B}{(x-2)^2}+\frac{C}{x-2}\\\\\Longrightarrow \boxed{\frac{-x+5}{(x-2)^2(x+1)}=\frac{\frac{2}{3} }{x+1}+\frac{1}{(x-2)^2}+\frac{-\frac{2}{3}}{x-2}}[/tex]

We can integrate the three fractions separately.

[tex]\Longrightarrow \int \frac{\frac{2}{3} }{x+1}dx+ \int \frac{1}{(x-2)^2}dx+\int \frac{-\frac{2}{3}}{x-2}dx\\\\\Longrightarrow \boxed{\frac{2}{3}\int \frac{1 }{x+1}dx+ \int \frac{1}{(x-2)^2}dx-\frac{2}{3}\int \frac{1}{x-2}dx}\\\\[/tex]

For the first integral let u=x+1 => du=dx, for the second let v=x-2 => dv=dx, and for the third integral let w=x-2 => dw=dx

[tex]\Longrightarrow \frac{2}{3} \int \frac{1 }{u}du+ \int \frac{1}{v^2}dv-\frac{2}{3}\int \frac{1}{w}dw\\\\\Longrightarrow \boxed{\frac{2}{3} \int \frac{1 }{u}du+ \int v^{-2}dv-\frac{2}{3}\int \frac{1}{w}dw}[/tex]

Use the rules of integration to integrate.

[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Natural Log Rule:}}\\\\ \int\frac{1}{x}dx=\ln(x) \end{array}\right} \ \ \boxed{\left\begin{array}{ccc}\text{\underline{Power Rule:}}\\\\ \int x^ndx=\frac{x^{n+1}}{n+1} \end{array}\right}[/tex]

[tex]\frac{2}{3} \int \frac{1 }{u}du+ \int v^{-2}dv-\frac{2}{3}\int \frac{1}{w}dw\\\\\Longrightarrow \frac{2}{3}\ln(u)-v^{-1}-\frac{2}{3}\ln(w)+C\\\\\Longrightarrow \frac{2}{3}\ln(x+1)-(x-2)^{-1}-\frac{2}{3}\ln(x-2)+C\\\\\Longrightarrow \frac{2}{3}\ln(x+1)-\frac{1}{x-2} -\frac{2}{3}\ln(x-2)+C\\\\\therefore \boxed{\boxed{\int \frac{-x+5}{(x^2-4x+4)(x+1)}=\frac{2}{3}\ln(x+1)-\frac{1}{x-2} -\frac{2}{3}\ln(x-2)+C}}[/tex]

Thus, the given integral is solved where "C" is some arbitrary constant that can be found given an initial condition.

Answers

The yield to maturity of the bond is -2.3%

What is the yield to maturity?

The yield to maturity (YTM) of a bond is the effective annual interest rate that an investor will receive if they hold the bond until maturity. It is calculated by taking into account the bond's coupon rate, the current market price, and the number of years until maturity.

In this case, the bond has a coupon rate of 8.8%, which means that it pays interest of 4.4% (8.8% / 2) per six months. The bond is currently selling for 112% of par value, which means that an investor would pay $1,120 for a bond with a face value of $1,000. The bond has 13 years remaining until maturity, which means that there are 26 six-month periods until maturity.

To calculate the YTM, we can use the following formula:

YTM = (C + (F - P) / n) / 2

Where:

C = coupon rateF = face valueP = current market pricen = number of periods until maturity

Plugging in the values, we get:

YTM = (4.4% + (1,000 - 1,120) / 26) / 2

YTM = -2.3%

The general formula for the nth term of a geometric sequence is given by: an = a1 * , where an represents the nth term.

Let's calculate the first four terms using this formula:

For n = 1:

a1 = 3 * 2^(1-1) = 3 * [tex]2^0[/tex] = 3 * 1 = 3

For n = 2:

a2 = 3 * 2^(2-1) = 3 * [tex]2^1[/tex] = 3 * 2 = 6For n = 3:

a3 = 3 * 2^(3-1) = 3 *[tex]2^2[/tex] = 3 * 4 = 12

For n = 4:

a4 = 3 * 2^(4-1) = 3 * [tex]2^3[/tex] = 3 * 8 = 24

Crowbar: Effort, MA, VR, Efficiency

User

A crow bar of length 1m is pivoted about 20cm from the tip and a load if 400N is lifted by applying an effort at the other end. Calculate the effort, MA, VR and efficiency.

ChatGPT

To calculate the effort, mechanical advantage (MA), velocity ratio (VR), and efficiency of the crowbar system, we need to use the principles of levers.

Given:

Length of the crowbar (L) = 1 m

Distance from the pivot to the load (d₁) = 20 cm = 0.2 m

Load (W) = 400 N

Effort (E) can be calculated using the equation:

E × MA = W × VR

Calculating Effort:

Let's consider the distance from the pivot to the effort (d₂). Since the crowbar is a rigid object, the sum of the moments on both sides of the pivot should be zero.

(E) × (d₂) = (W) × (d₁)

E × (d₂) = W × (d₁)

E × (d₂) = 400 N × 0.2 m

E × (d₂) = 80 N·m

Since we are given the length of the crowbar (L) = 1 m, we can substitute d₂ = L - d₁.

E × (L - d₁) = 80 N·m

E × (1 m - 0.2 m) = 80 N·m

E × 0.8 m = 80 N·m

E = 80 N·m / 0.8 m

E = 100 N

Therefore, the effort required to lift the load is 100 N.

Calculating Mechanical Advantage (MA):

MA = (L - d₁) / d₁

MA = (1 m - 0.2 m) / 0.2 m

MA = 4

The mechanical advantage of the crowbar system is 4.

Calculating Velocity Ratio (VR):

VR = L / d₁

VR = 1 m / 0.2 m

VR = 5

The velocity ratio of the crowbar system is 5.

Calculating Efficiency:

Efficiency (η) = (MA / VR) × 100

η = (4 / 5) × 100

η = 80%

The efficiency of the crowbar system is 80%.

To summarize:

Effort (E) = 100 N

Mechanical Advantage (MA) = 4

Velocity Ratio (VR) = 5

Efficiency (η) = 80%

the phsican orders 15mg of tramadol (liq). On hand is 30mg/2ml vials. how many ml will the MA administer

ChatGPT

To calculate the amount of liquid tramadol the physician will administer, we need to determine the volume (in milliliters) of the medication.

Given:

Ordered dose of tramadol = 15 mg

Concentration of tramadol in vials = 30 mg/2 ml

To find out the required volume, we can set up a proportion:

(30 mg / 2 ml) = (15 mg / x ml)

Cross-multiplying, we have:

30 mg * x ml = 15 mg * 2 ml

30x = 30

Dividing both sides by 30:

x = 1

The required volume of liquid tramadol to administer the ordered dose of 15 mg will be 1 ml.

Therefore, the physician will administer 1 ml of tramadol.

Answer:

the MA will administer 1 ml of tramadol liquid.

Jessica needs extra money to buy a truck to start up a delivery service. She takes out a simple interest loan for $8000 for 4 months at a rate of 9.25%. How much interest must she pay and what’s the maturity value of the loan?

Answers

The maturity value of the loan is $8246.65. Jessica will need to pay back this amount at the end of the 4 months.

How to solve for the maturity value

Here, P = $8000, R = 9.25%/100 = 0.0925 (in decimal form), and T = 4 months = 4/12 years = 0.3333 years.

Substituting these values into the formula, we find:

I = $8000 * 0.0925 * 0.3333 ≈ $246.65

So, Jessica must pay about $246.65 in interest.

The maturity value of the loan is the principal plus the interest. So, the maturity value (MV) is given by:

MV = P + I

MV = $8000 + $246.65 = $8246.65

So, the maturity value of the loan is $8246.65. Jessica will need to pay back this amount at the end of the 4 months.

Answers

Answer:

85 feet

Step-by-step explanation:

To find the distance traveled by the laser pointer's beam, we can use the Pythagorean theorem. The laser beam forms a right triangle with the tower as one side and the distance traveled as the hypotenuse.

Let's denote the distance traveled by the laser beam as x. We can set up the following equation using the Pythagorean theorem:

x^2 = 40^2 + 75^2

Simplifying this equation:

x^2 = 1600 + 5625

x^2 = 7225

Taking the square root of both sides:

x = √7225

x = 85

Therefore, the laser pointer's beam has traveled approximately 85 feet.

⇒ 32% of the people who prefer French fries also prefer pizza

⇒ 60% of the people surveyed prefer burgers, and 40% prefer pizza.

To find out what percentage of people who prefer French fries also prefer pizza,

According to the given information.

60% of the people surveyed prefer burgers over pizza, and of those people, 48 prefer french fries over salad.

This means that 40% of the people surveyed prefer pizza over burgers.

Now, we have to find out what percentage of the people who prefer French fries also prefer pizza.

We know that 48 people prefer French fries over salad,

But we don't know how many of those people prefer burgers or pizza. However, we do know that all of the people surveyed fall into one of these categories:

They either prefer pizza or burgers.

Therefore,

Assume that the remaining 52% of the people surveyed prefer burgers over pizza.

To find the percentage of people who prefer French fries and pizza,

Use a proportion:

⇒ 48 / (40% of 75) = x / 100%

Solving for x, we get:

⇒ x = (48 / (40% of 75 ) x 100%

      = 32%

Therefore,

32% of the people who prefer French fries also prefer pizza.

To find out what percentage of people prefer pizza,

We know that 40% of the people surveyed prefer pizza over burgers, and we know that 28 of the people who prefer pizza also prefer salad.

To find the percentage of people who prefer pizza,

Use a proportion:

⇒ (40% of 75) = y / 100%

Solving for y, we get:

⇒ y = (40% of 75) x 100% = 30

Therefore,

30 people prefer pizza.

To find the percentage of people who prefer pizza, we can use another proportion:

⇒ 30 = (100% - z) / 100% x 75

Solving for z, we get:

z = 60%

Therefore, 60% of the people surveyed prefer burgers, and 40% prefer pizza.

product is to multiplication; difference is to

Answers

In mathematics, the term "difference" is commonly associated with subtraction. Subtraction is an arithmetic operation that involves finding the difference between two numbers or quantities.

When we subtract one number from another, we are essentially finding the difference between them. The result of a subtraction operation is called the difference. For example, in the expression 10 - 5, the difference is 5, indicating that the number 5 is the result of subtracting 5 from 10.

Subtraction is denoted by the minus sign "-" or by using the word "minus" or "subtract" in mathematical expressions. For instance, in the equation 8 - 3, we are subtracting 3 from 8 to find the difference.

The concept of difference is fundamental in various mathematical applications. It allows us to compare quantities, measure distances, determine changes, and solve various problems. For instance, when analyzing data sets, we often calculate the differences between values to understand patterns, trends, or changes over time.

The difference between two numbers can be positive, negative, or zero. If the minuend (the number from which subtraction is performed) is greater than the subtrahend (the number being subtracted), the difference is positive. If the subtrahend is greater, the difference is negative. When both numbers are equal, the difference is zero.

For example, in the subtraction 7 - 3, the difference is 4. In the subtraction 5 - 9, the difference is -4. And in the subtraction 6 - 6, the difference is 0.

Overall, the concept of difference is a crucial aspect of subtraction, providing a measure of the numerical distance between two quantities. It allows us to express the result of a subtraction operation and plays a significant role in various mathematical calculations and analyses.

Evaluating the function f(x) = -2x + 5 when x = -1 is 7

What is evaluating a function?

Evaluating a function involves calculating the value of the function for a given input or argument. When you evaluate a function, you substitute the input value into the function's expression and perform the necessary computations to determine the corresponding output value.

A function is typically defined by an equation or rule that relates the input value (often represented as x) to the output value (often represented as f(x)). By evaluating the function, you can determine the specific output value corresponding to a particular input

In this problem given, we can evaluate the function by substituting the value for x into it.

f(x) = -2x + 5

f(-1) = -2(-1) + 5

f(-1) = 2 + 5

f(-1) = 7

Simonne used the following steps to simplify the given expresion 12 minus 3 (negative 2 x + 4)

Answers

The simplified expression is 6x. Simonne simplifies the expression 12 minus 3 times negative 2x plus 4 to 6x by following the order of operations, performing the necessary multiplication and subtraction.

To simplify the expression 12 minus 3 times negative 2x plus 4, Simonne follows the order of operations (also known as PEMDAS) to ensure the correct simplification.

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's break down the steps:

Step 1: Simplify within parentheses

The expression within the parentheses is -2x + 4. Since there is no exponent or multiplication/division to perform within the parentheses, we move to the next step.

Step 2: Apply the multiplication

The multiplication operation is between 3 and the expression within parentheses (-2x + 4). We distribute the 3 to each term within the parentheses by multiplying each term by 3:

3*(-2x) + 3*4

This simplifies to:

-6x + 12

Step 3: Apply subtraction

The original expression is 12 minus the result from Step 2 (-6x + 12):

12 - (-6x + 12)

To subtract a negative, we can rewrite the expression as:

12 + (-1)*(-6x + 12)

Next, we distribute the -1 to each term within the parentheses:

12 + (-1)*(-6x) + (-1)*12

Simplifying, we have:

12 + 6x - 12

The 12 and -12 cancel each other out, leaving us with:

6x.

6TH GRADE MATHstudents at the wild outdoors camp choose one or two morning activities each day. this morning , the ratio of campers who will be horseback riding to campers who will be canoeing is 5 to 3. what percentage of campers is horseback riding?

Answers

Then 62.5% of the campers at the Wild Outdoors camp this morning will be horseback riding

To find the percentage of campers that will be horseback riding, we need to first add the ratio together to get the total number of parts. In this case, the ratio of horseback riding to canoeing is 5:3, so there are 5 + 3 = 8 parts in total.

To find the percentage of campers that will be horseback riding, we divide the number of parts for horseback riding by the total number of parts, then multiply by 100 to get the percentage.

So, 5 parts out of 8 parts are for horseback riding. This is equivalent to 5/8 or 0.625 as a decimal. To find the percentage, we multiply by 100, which gives us 62.5%.

The value of the green box is 0.

To solve the equation[tex]{3x-6} +{ x-2}= \frac{3x-6 + x - 2}{1} = 180$[/tex], we first simplify the left side of the equation:

[tex]{3x-6}{x-2} = \frac{(3x-6) + (x-2)}{x-2} = \frac{4x-8}{x-2}$$[/tex]

Now we can rewrite the original equation as:

[tex]\frac{4x-8}{x-2} = 180$$[/tex]

Next, we can multiply both sides of the equation by x-2 to eliminate the denominator:

[tex]$$(4x-8) = 180(x-2)$$[/tex]

Expanding the right side gives:

[tex]$$(4x-8) = 180x - 360$$[/tex]

Simplifying and moving all the terms to the left side gives:

[tex]$$176x - 352 = 0$$[/tex]

Adding 352 to both sides gives:

176x = 352

Finally, dividing both sides by 176 gives:

[tex]x = \frac{352}{176} = 2[/tex]

Therefore,  since there is no constant term on the left side of the equation after combining like terms.
