What are the zeros of the polynomial Y=(x+3)(x-2)?

We utilize the differentiation method to obtain the derivative of a function. This entails calculating the limit of the ratio of the change in output (y value) to the change in input (x value). The formula then yields the function's derivative. f'(x) = [tex]\lim_{h \to 0} \frac{f(x+h) - f(x)}{h}[/tex].

Determining the derivative of a function is a simple process. Initially, you must establish the sort of function you are dealing with.

Once the kind of function has been decided, the variables of the function must be identified.

The power rule is then used to determine the derivative of each of the terms.

Lastly, you must combine all of the terms to obtain the overall derivative.

Positive correlation means that both variables tend to increase (or decrease) together. Thus, Option A is the answer.

Positive correlation refers to a relationship between two variables in which an increase in one variable is associated with an increase in the other variable. Negative correlation, on the other hand, refers to a relationship in which an increase in one variable is associated with a decrease in the other variable. No correlation means that there is no relationship between the two variables.

To determine the strength of a correlation, we can use a statistical measure called the correlation coefficient, which ranges from -1 to 1. A correlation coefficient of 1 indicates a perfect positive correlation, a correlation coefficient of -1 indicates a perfect negative correlation, and a correlation coefficient of 0 indicates no correlation.

Answer: First Choice. 9r² + r -4

Step-by-step explanation:

Given information

Side 1 = 5r²+3

Side 2 = 4r²-6r+1

Side 3 = 7r-8

Formula for the perimeter of the triangle

Perimeter = Side 1 + Side 2 + Side 3

Substitute values into the formula

Perimeter = (5r² + 3) + (4r² - 6r + 1) + (7r - 8)

Simplify the expression

Perimeter = 5r² + 4r² + 7r - 6r + 3 + 1 - 8

Perimeter = 9r² + r + 4 - 8

Perimeter = [tex]\Large\boxed{9r^2+r-4}[/tex]

Step-by-step explanation:

multiple the length value by 2.54

The conversion of 63 f to c is equivalent to approximately 17.22°C .

For 63 (degrees) Fahrenheit we write 63 °F, and (degrees) Celsius or centigrades are denoted with the symbol °C.

As a side note: the unit of temperature Fahrenheit is named after the German physicist Daniel Gabriel Fahrenheit.

So if you have been looking for 63 °F to °C, then you are right here, too.

To convert a temperature from Fahrenheit (°F) to Celsius (°C), you can use the formula:

°C = (°F - 32) * 5/9

So, to convert 63°F to °C, you can substitute 63 for °F in the formula:

°C = (63 - 32) * 5/9

= 31 * 5/9

= 155/9

≈ 17.22°C

Therefore, 63°F is equivalent to approximately 17.22°C (rounded to two decimal places).

∠6 and ∠8 are vertical angles.

∠2 and ∠7 are same side exterior angles

∠3 and ∠ 5 are alternate interior angles

∠1 and ∠2 are supplementary angles

Transversal angles are angles that are formed when a transversal line intersects two other lines in a plane. A transversal is a line that intersects two or more other lines, which are called the base lines.

When a transversal intersects two parallel lines, it creates eight angles. These angles can be classified into three types:

Corresponding angles: Pairs of angles that are on the same side of the transversal and in corresponding positions relative to the parallel lines. Corresponding angles are congruent when the parallel lines are cut by the transversal.

Alternate interior angles: Pairs of angles that are on opposite sides of the transversal and between the parallel lines. Alternate interior angles are congruent when the parallel lines are cut by the transversal.

Alternate exterior angles: Pairs of angles that are on opposite sides of the transversal and outside the parallel lines. Alternate exterior angles are congruent when the parallel lines are cut by the transversal.

The total cost for each combination with the special offer would be:

Massage, leg wax, and manicure: £68.25

Massage, facial, and eyelash tint: £59.25

Massage, leg wax, and eyelash tint: £57.75

We can try out the different possibilities and calculate the total cost of each.

Let's start by listing the prices of the treatments she's interested in:

Massage: £35

Facial: £31

Leg wax: £29

Manicure: £27

Eyelash tint: £13

Now, we can try out the different combinations of 3 treatments and calculate their total cost:

Massage, facial, and leg wax:

Total cost = £35 + £31 + £29 = £95

With 25% off, the cost would be £71.25, which is over Lou's budget of £60, so this combination is not possible.

Massage, facial, and manicure:

Total cost = £35 + £31 + £27 = £93

With 25% off, the cost would be £69.75, which is still over Lou's budget of £60, so this combination is also not possible.

Massage, leg wax, and manicure:

Total cost = £35 + £29 + £27 = £91

With 25% off, the cost would be £68.25, which is within Lou's budget of £60. Therefore, this combination is possible.

Massage, facial, and eyelash tint:

Total cost = £35 + £31 + £13 = £79

With 25% off, the cost would be £59.25, which is within Lou's budget of £60. Therefore, this combination is also possible.

Massage, leg wax, and eyelash tint:

Total cost = £35 + £29 + £13 = £77

With 25% off, the cost would be £57.75, which is within Lou's budget of £60. Therefore, this combination is also possible.

From the above calculations, we can see that Lou can choose from three possible combinations of treatments that fit within her budget and qualify for the special offer:

Massage, leg wax, and manicure

Massage, facial, and eyelash tint

Massage, leg wax, and eyelash tint

The total cost for each combination with the special offer would be:

Massage, leg wax, and manicure: £68.25

Center on the y-axis means h = 0.

Diameter of 12 units means r = 6.

x² + (y – 3)² = 36       Yes

x² + (y – 5)² = 6         No

(x – 4)² + y² = 36       No

(x + 6)² + y² = 144      No

Based on the concept of measurement, the decimal equivalent is 0.75.

To start, it is important to understand that time is a form of measurement that can be expressed in a variety of ways, including hours, minutes, seconds, and even fractions of seconds. Decimals are also a common way to express time, especially in situations where precision and accuracy are important.

To convert 45 minutes into a decimal, you need to first understand the relationship between minutes and hours.

There are 60 minutes in one hour, which means that 45 minutes is equivalent to 0.75 hours

=> (45/60 = 0.75).

Once you have this decimal equivalent, you can express it in a variety of ways, depending on the context.

If you were measuring time in terms of a workday (i.e. 8 hours), 0.75 hours would be equal to 45 minutes. On the other hand, if you were measuring time in terms of a percentage of an hour (i.e. 100%), 0.75 hours would be equal to 75%.

Answer:

56%

Step-by-step explanation:

The probability of snow on Tuesday is 20%, which means the probability of no snow on Tuesday is 100% - 20% = 80%.

Similarly, the probability of snow on Wednesday is 30%, which means the probability of no snow on Wednesday is 100% - 30% = 70%.

The probability that it will not snow on either day is the product of the probabilities of no snow on Tuesday and no snow on Wednesday:

(80%)(70%) = 56%

So the probability that it will not snow on either day is 56%.

Therefore, when  we put x=1 and y=2, the equation 3(x+2y)-2x+10 simplifies to 23.

Step-by-step explanation:

To evaluate and simplify the expression first we have to put x=1 and y=2 in the equation as given in the question,

3(x+2y)-2x+10 = 3(1+2(2))-2(1)+10

                       =3(1+2(2))-2+10

                       = 3(1+4)+8

                       = 3(5)+8

                       = 15+8

                       = 23

Therefore, when  we put x=1 and y=2, the equation 3(x+2y)-2x+10 simplifies to 23.
