Consequently, the function's average rate of change is -11.

A mathematical expression, rule, or law that describes the relationship between two independent variables and one dependent variable In mathematics, functions exist everywhere, and they are crucial for creating physical links in the sciences.

The function is given by .

The ratio of the dependent variable's change to the independent variable's change is referred to as the rate of change.

f(x)=[tex]x^{2}[/tex]-6x+6

x ranges from -7 to 2, with 2 being the highest value.

=> f(-7) = 49 + 42 + 6 = 97.

=> f(2) =- 12 + 6+4 = -2.

The average rate of change is

f(-7)-f(2)/-7-2

=> 97-(-2)/-9

=> 99/-9

=> -11

The value of y will be 104 using direct proportion property between x and y.

What is direct proportion ?

Direct proportion is the relation between two quantities where ratio of these two is equal to a constant.

It is represented by proportional symbol , "∝"

Let's consider constant is m.

For given que,

As y and x are in direct proportion,

y ∝ x

or x ∝ y

eliminating the proportionality,

y = x*m where m is any constant.

y/x = m

Given when y = 64 , then x = 8

So, m = 64/8

          = 8

The number of gallons of gas that Lora can fill in 1 minute will be 18/5 or 3.6 gallons.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

At a gas station, Lora took 1/6 minute to fill 3/5 gallons of gas. And we know that the ratio will remain constant.

Let 'x' be the number of gallons. Then the amount of gallons in each minute is calculated as,

(3/5) / (1/6) = x / 1

Simplify the equation, then we have

(3/5) / (1/6) = x / 1

(3/5) × 6 = x

x = 18 / 5

x = 3.6 gallons

The number of gallons of gas that Lora can fill in 1 minute will be 18/5 or 3.6 gallons.

The surd expression 1 + [√2 / (3 - √2)²]  can be simplified as (61 + 11√2/ 49) where a is 61/49 and b is 11/49

When evaluating an expression, the first step is to identify the operators and operands in the expression. The operators are the symbols that direct the operation. The operands are the values or variables that the operators act upon. Once the operators and operands are identified, the expression can be evaluated by applying the order of operations to the expression. This includes performing operations inside parentheses first, then multiplication and division, followed by addition and subtraction.

In the case of a surd expression, the same process should be followed. However, it is important to note that surds can be simplified using the rules of indices. This means that surds with the same base value can be combined using addition and subtraction.

In the give problem, we have

1 + [√2 / (3 - √2)²] can be written in the form a + b√2

1 + [√2 / (3 - √2)²] can be simplified using a calculator to give us a value of;

Answer:

the range of possible weights for the letters is 98-105 ounces.

Step-by-step explanation:

To determine whether 101 ounces is a reasonable estimate for the weight of 25 letters that each weigh between 3.92 ounces and 4.2 ounces, we need to calculate the range of possible weights for the letters.

The minimum weight for the letters is 25 * 3.92 ounces = 98 ounces. The maximum weight for the letters is 25 * 4.2 ounces = 105 ounces. Therefore, the range of possible weights for the letters is 98-105 ounces.

Since 101 ounces falls within this range, it is a reasonable estimate for the weight of the letters.

Moving this barrel up a ramp required around 339.41 foot-pounds of labour from Alexa.

W = F.d

When the dot product is expanded, we get:

W=Fd cos(Ф)

We can plainly see from the given statement that:

applied force = F = 120 pounds

d = 4 feet for displacement.

F's angle with the horizontal is Ф = 45 degrees.

When the formula's values are substituted, we obtain:

W = 4 * 120 * cos (45)

W equals 339.41 foot pounds.

Answer: 7

Step-by-step explanation:

Complex number equal to (5 + 12i) − (9i^2 − 6i), for i = √ -1 is 14 + 18i.

Complex numbers are the numbers that are expressed in the form of a+ib where, a,b are real numbers and  ‘i’ is an imaginary number called “iota”. The value of i = (√-1)

Given number is (5 + 12i) − (9i^2 − 6i).

We know that i^2 = -1.

Using this we get number = 5+12i+9+6i

Step-by-step explanation: To determine if this graph represents a function, we use what is called the vertical line test.

In other words, if we can draw a vertical or straight up and down line that passes through more than one point on the graph, the relation is not classified as a function.

In this case, it's impossible to draw such a line that hits more than one point on the graph so the relation is a function.

The probability that the card will be a spade or a club 50%

Probability in math is referred as  how likely an event is to occur, or how likely it is that a proposition is true.

Here we have given that a card is drawn from a standard deck of 52 playing cards.

And we need to find  the probability that the card will be a spade or a club and we have to express your answer as a fraction or a decimal number rounded to four decimal places.

While we looking into the given question, we have identified the the total number of cards is 52.

And the number of spade cards = 13 and the number of club cards = 13

Therefore, the total number of spade and club cards

=> 13 + 13

=> 26

Therefore, the probability of getting a spade or  a club from a single draw is,

The average deviation from the mean is 0.19 that can be calculated from the mean.

An average is calculated for a set of numbers that are of the same value range.

Mean = (32.52+32.14+32.61+32.75)/4 = %32.50

Standard deviation =

|32.50-32.52| = 0.02

|32.50-32.14| = 0.36

|32.50-32.61| = 0.11

|32.50-32.75| = 0.25
