Find the distance between (3, 11) and (4, 3). Provide an answer accurate to the nearest tenth.​

If you're given a false equation and you multiply both sides by the same non-zero number, the resulting equation will also be a false equation.

If you're given a false equation and you multiply both sides by the same non-zero number, the resulting equation will also be a false equation.

This is because the equation was already unbalanced, and multiplying both sides by the same non-zero number does not change that.

For example, consider the equation 2 + 3 = 6. This is a false equation. If we multiply both sides by 2, we get:

(2 + 3) × 2 = 6 × 2

4 + 6 = 12

The resulting equation 4 + 6 = 12 is also a false equation.

The statement must be true about p(x): "The remainder when p(x) is divided by x - 2 is -5". which is the correct answer that would be an option (D).

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

For a polynomial p(x), the value of p(2) is -5.

The remainder when p(x) is divided by x - 2 is -5.

This statement must be true because, by definition, the remainder of a polynomial division is the value of the polynomial when it is evaluated at the divisor. In this case, the divisor is x - 2, so the remainder when p(x) is divided by x - 2 is p(2). Since the value of p(2) is given as -5, it follows that the remainder when p(x) is divided by x - 2 must be -5.

None of the other statements are necessarily true based on the information given.

Answer:1. Let  a = 1  and  b = 1 .

2. Now this means that  a = b .

3. If we multiply both sides by  a  we get  a^{2} = ab .

4. If we then subtract  b^{2}  from both sides we would have  a^{2} - b^{2} = ab - b^{2} .

5. We can then factorise both sides to get  (a + b)(a - b) = b(a - b) .

6. Dividing both sides by  (a - b)  would give us  a + b = b .

7. Substituting back the values of  a = 1  and  b = 1  would give us that  1 + 1 = 1 .

The diameter of the grindstone is decreasing at a rate of 5/(πr) cm/hr.

Therefore the answer is b) 5/ (πr) cm/hr.

The grindstone is losing material at a rate of 50 cm³/hr, and since it is a cylinder, we can use the formula for the volume of a cylinder to find the rate at which its diameter is decreasing.

The volume of a cylinder is given by:

[tex]V= \frac{ \pi D^{2} h}{4}[/tex]

where V is the volume, d is the diameter and h is the height (in this case the thickness of the grindstone).

We know that the grindstone is losing material at a rate of 50 cm³/hr, and that the grindstone's thickness is 10 cm. To find the rate at which the diameter is decreasing, we need to find the rate at which the radius is decreasing, which we can find by differentiating the volume equation with respect to time.

So

[tex]\frac{dV}{dt} = -50\ cm^{3}/hr[/tex]

[tex]\frac{d(\frac{\pi\\D^{2}h }{4}) }{dt} = -50\ cm^{3}/hr[/tex]

[tex]\frac{2}{4}\pi Dh\frac{dD}{dt} = -50\ cm^{3}/hr[/tex]

Substitute the known values,

[tex]\frac{2}{4}\pi *(D)*(10cm)\frac{dD}{dt} = -50\ cm^{3}/hr[/tex]

[tex]\frac{dD}{dt}= (-50 cm^3/hr)*\frac{4}{2\pi *(D cm)*(10 cm)}[/tex]

[tex]\frac{dD}{dt}= \frac{-10}{\pi D}cm/hr[/tex]

Percentage error in the area is 79.84 %

Percentage error is defined by the difference between actual value and estimated value while comparing to the actual value and expressed in percentage.

given, sides of a rectangle are 6.2 cm and 4.8 cm.

actual length = 6.2 cm

actual width = 4.8 cm

hence, area of rectangle = length × width

                                       = 6.2 cm x 4.8 cm

actual area = 29. 76 square centimeters.

measured length = 2 cm

measured width = 3 cm

measured area = 2 x 3 = 6 square cm

percentage error in the area = (actual area - measured area) / actual area ×100

                                                      =(29.76 - 6) / 29.76 × 100

Answer:

  (a)  $1049.15

Step-by-step explanation:

You want to know the interest earned by an account that pays 3.2% interest compounded semiannually if the balance is $6049.15 after 6 years.

The formula for the balance of an account earning compound interest is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.

We have ...

  6049.15 = P(1 +0.032/2)^(2·6) = P(1.016^12)

The amount of interest earned is the difference between the account balance and the principal:

  interest = 6049.15 -(6049.15/1.016^12) ≈ 1049.15

The total amount of interest earned is $1049.15.

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

a. Yes, the amount of water in the pool is a function of the number of minutes. This is because, for each input value of the number of minutes, there is a unique output value of the amount of water in the pool.

Where the function is y = 17x  

b. The domain of the function is the set of all possible values of the input, which in this case is the number of minutes. The domain is continuous because it includes all possible values within a range (in this case, all possible values of the number of minutes), rather than only a set of specific, discrete values.

Assume that the capacity of the swimming pool with water is 10000 gallons.

So it completed fully fills with water in 588.2 (=10000/17) minutes

You have to first convert them to improper fractions, by multiplying the whole with the denominator (bottom number). And then you add the answer with the numerator (top number). This answer is then the numerator of the improper fraction, and the denominator remains the same. Then you add the two improper fractions. If the denominators are different, you find the lowest common multiple (LCM) of the denominators and multiply both the numerator and denominator so that the new denominator is the lowest common multiple. Then you add the numerators and keep the denominator the same

Step-by-step explanation:

The age of Kate will be 16 years.

The age of Leo will be 20 years.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Kate is 4 years younger than Leo.

And, Twice Kate's age minus 3 is the same as Leo's age plus 9.

Now,

Let the age of Leo = x

So, The age of Kate = x - 4

Here, Twice Kate's age minus 3 is the same as Leo's age plus 9.

Hence, We can formulate;

⇒ 2 (x - 4) - 3 = x + 9

Solve for x as;

⇒ 2x - 8 - 3 = x + 9

⇒ 2x - x = 9 + 11

⇒ x = 20 years

Thus, The age of Leo = x

                                 = 20 years

So, The age of Kate = x - 4

                               = 20 - 4

Using leaner equation we find that After 12 years from now will Jerry's age be (2/3) of the combined ages of his brother and sister at that time.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

Let Jerry's brother present age be X years,

Then Jerry's present age will be 2x

And his sister's present age will be 2X - 6

And let y be  the  number of years from now when Jerry's age = (2/3) of combined age of his brother and sister.

So we have that,

(2X + y)  = (2/3) [(X + y) + (2X - 6 + x)]

simplify the above equation

2X + y = (2/3) [3X + 2y - 6]

multiply through by 3/2

3X + (3/2)y = 3X + 2y - 6

subtract  3X from both sides

(3/2)y = 2y - 6

subtract 2y from both sides

-1/2y = -6

By evaluating the quadratic equations we will get:

3c(a-4)+3d(a+5) =  3*(a^3 - 8a^2 + 102a + 22)

Here we have two quadratic functions:

c(x)=x^3-2x and d(x)=4x^2-6x+8

And we want to find the value of the expression:

3c(a-4)+3d(a+5)

First, let's evaluate the functions in these values:

3*c(a - 4) = 3*[ (a - 4)^3 - 2*(a - 4)] = 3*(a - 4)*[ (a - 4)^2 - 2]

               = 3*(a -4)*(a^2 - 8a + 16 - 2)

               = 3*(a - 4)*(a^2 - 8a + 14)

               = 3*(a^3 - 12a^2 + 46a - 56)

3*d(a + 5) = 3*[ 4*(a + 5)^2 - 6*(a + 5) + 8]

                = 3*[ 4a^2 + 40a + 100  -6a - 30 + 8]

                = 3*[4a^2 + 36a + 78]

Then the expression is:

3c(a-4)+3d(a+5) = 3*(a^3 - 12a^2 + 46a - 56) + 3*[4a^2 + 36a + 78]

                           = 3*(a^3 - 12a^2 + 46a - 56 + 4a^2 + 36a + 78)

Total angles of a triangle = 180

Since it's the total, we add these three angles

[tex](x - 31) + (x) + (x + 43) = 180[/tex]

Next, we combine like terms

[tex]3x + 12 = 180[/tex]

Next, you can subtract 12 from both sides to get numbers on one side

[tex]3x = 168[/tex]

Last step is to divide by 3 to get the X alone

[tex]x = 56[/tex]

Answer:  

x = 56

F = 25

R = 99

O = 56

Step-by-step explanation:

all triangles equal 180 degrees

that means that when you add angle F, O, + R, you will get 180

create the formula based on this info:

F + R + O = 180

x - 31  + x + 43 + x = 180

solve:

-31+43+x+x+x = 180

12 + 3x = 180

3x = 168

x = 56

now plug in x and find each angle

F = x - 31

F = 56 - 31

F = 25

R = x + 43

R = 56 + 43

R = 99

O = x

O = 56

The checkpoint Odalis will be when they catch up to Jaquan is 0.1 km.

Given that, Jaquan passed a checkpoint jogging at a constant speed of 9 km/hr.

2 minutes later Odalis passed the same checkpoint.

Odalis runs at a constant speed of 12 km/hr.

We know that, 1 hour = 60 minutes

So, 2 minutes = [tex]\frac{2}{60}[/tex] hour

= [tex]\frac{1}{30}[/tex] hour

So, the distance = [tex]9\times\frac{1}{30}[/tex]

When the speed is 12 km/hr, we get

Distance = [tex]12\times\frac{1}{30}[/tex]

so any data point more than 205 (110 + 142.5) is considered an outlier, including 225.

Yes, because 225 minutes is greater than 205 minutes.

Outlier rules, also known as outlier detection algorithms, are algorithms designed to detect the presence of outliers in a dataset.

Outliers are data points that are significantly different from the rest of the data, and can be caused by measurement error, experimental error, or some other anomaly.

Outlier rules are used to identify and remove outliers from data sets in order to improve the accuracy of data analysis and modeling.

Outlier rules typically use some combination of statistical measures, such as mean, median, and standard deviation, to detect the presence of outliers in the data.

In this question answer is

Yes, because 225 minutes is greater than 205 minutes.

This can be determined by using the outlier rule

which states that any data point that is more than 1.5 times the interquartile range (IQR) away from the upper quartile (Q3) is considered an outlier.

The IQR is calculated as Q3 - Q1,

which in this case is

110 - 15 = 95. Therefore,

1.5 times the IQR is 95 x 1.5 = 142.5.

The upper quartile (Q3) is 110,

so any data point more than 205 (110 + 142.5) is considered an outlier, including 225.
