The function that increases at a faster rate on 0 to infinity is g(x) = 2ˣ

An average rate measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

The functions are given as:

f(x) = x² --- quadratic

g(x) = 2ˣ --- exponential

The exponential function has the same base as the power of the quadratic function.

This means that the exponential function would increase faster from the point where f(x) = g(x)

This is illustrated using the following table

x      0   1   2   3   4    5

f(x)  0    1   4   9   16   25

g(x)  1   2    4   8   16   3

The catcher must throw the ball in a distance of 127.2 feet to force a runner out at second base.

From the figure we understands that it is a right angled triangle.

The hypotenuse of a right triangle is formed by the line from home plate to second base. The triangle's two sides are each 90 feet.

We can calculate the length of the hypotenuse using the Pythagorean theorem:

90² + 90² = c²

= 8100 + 8100 = c²

= 16200 = c²

c = √16200

c = 127.2

c = 127 feet

As a result, the distance that the catcher must throw the ball to get a runner out at second base is 127 feet.

Using simultaneous equations, the price of one adult ticket is $4 and one student ticket is $7.

Simultaneous equations are two or more equations solved concurrently.

Sales of Tickets:

First day of ticket sales         1               8               $60

Second day of ticket sales   5              4               $48

Let the price per adult ticket = a and students ticket = s

Equation 1: a + 8s = 60

Equation 2: 5a + 4s = 48

Multiply equation 1 by 5:

Equation 3: 5a + 40s = 300

Subtract equation 2 from equation 3:

5a + 40s = 300

-

5a + 4s = 48

36s = 252

s = 7

= $7

In equation 1, substitute s = 7:

a + 8s = 60

a + 8(7) = 60

a + 56 = 60

a = 4

In this question, we use the theory of LCM (Least Common Multiple) for finding the numbers which are divisible by 2,5 and 10. As we know, in arithmetic, the LCM is the smallest or least positive integer that is divisible by both a and b. So, in this question we need to calculate the LCM of 2,5

step 1

Solution

LCM of 2,5,10 is 10

So, if a number is divisible by 10 then it will be divisible by 2,5,10

Like 60,100,120,450,600

step-by-step answer:

For example, let us take two positive integers 4 and 6. Multiples of 4 are: 4,8,12,16,20,24… Multiples of 6 are: 6,12,18,24…. The common multiples for 4 and 6 are 12,24,36,48…and so on.

2, 5 and 10 (LCM by Division Method).

LCM of 2, 5 and 10 = 2X5

                                 = 10

we get LCM of 2, 5 and 10 is 10.

So, if a number is divisible by 10

Then it will be divisible by 2,5,10.

Therefore, any number which is multiple of 10 or which is divisible by 10. We say it will be divisible by 2,5,10.

Like- 10, 20, 30, 40, 50, 60, 70, 80 etc.

Thus, 10, 20, 30, 40, 50 are 5 numbers which are divisible by 2,5 and 10.

The Taylor series of a function f(x) at point a is an infinite sum of terms that approximates the value of the function near point a. The general form of the Taylor series of f(x) at a is:

f(x) = f(a) + (x - a)f'(a) + (x - a)^2/2! f''(a) + (x - a)^3/3! f'''(a) + ...

In the case of e^x, the function is infinitely differentiable, so all its derivatives are equal to itself. Hence the Taylor series at a=8 is:

e^8 + (x-8)e^8 + (x-8)^2/2! e^8 + (x-8)^3/3! e^8 + (x-8)^4/4! e^8 + ....

by taking the degree 4 terms we can find the Taylor series of e^x at a = 8 up to the degree 4 terms, which is

86 ml of dirt will remain after 9 passes

An equation is an expression showing the relationship between numbers and variables.

Let y represent the amount of dirt on the floor after x passes, hence:

y = abˣ

During each pass, 17% of the dirt is removed, therefore b = 100% - 17% = 0.83

If the floor initially has 460.0 ml of dirt, then a = 460.

The equation becomes:

y = 460(0.83)ˣ

The r represents the correlation coefficient which has a value 0.89 for the given case.

we can say that there is a positive association between the life expectancy of citizen and the average number of TVs in households.

the r value is close to +1 which means that the association is close to linear relation .

By applying the required transformation, the coordinates of the translated point Q' are (-1, -11).

A translation is a type of transformation in geometry that moves every point of a figure in a fixed direction and by a fixed distance, without changing its size or shape. It is one of the basic geometric transformations along with rotation, reflection, and dilation.

Coordinates are a set of values that determine the position of a point in a certain space. In a two-dimensional space, coordinates are usually represented by an ordered pair of numbers (x, y), where x is the horizontal distance from a fixed point called the origin and y is the vertical distance from the origin. In a three-dimensional space, coordinates are represented by an ordered triple of numbers (x, y, z). Coordinates are often used to locate points in space, to describe the position of objects, and to plot graphs.

To find the coordinates of the translated point Q', we can use the rule that in a translation, the x-coordinate is decreased by the horizontal translation distance and the y-coordinate is decreased by the vertical translation distance.

Given that point Q has coordinates (5, -6) and is translated 6 units left and 5 units down, we can find the coordinates of the translated point Q' as follows:

x' = x - 6 (horizontal translation distance)

y' = y - 5 (vertical translation distance)

So the coordinates of the translated point Q' are:

x' = 5 - 6 = -1

y' = -6 - 5 = -11

The enclosed area between the 2 equations, x = 7y² and x = 4 + 6y² is 32/3 sq units

Here equation 1 is x = 7y²

and equation 2 is x = 4 + 6y²

To find the area enclosed between the region, we need to first find the points where these two lines meet.

This implies,

eq 1 = eq 2

or, 7y² = 4 + 6y²

or, y² = 4

or, y = ±2

Now if we see the graph with respect to y, the area between the y-axis and eq 2 is greater than that of the y-axis and equation 1.

Now area is enclosed between 2 lines with respect to x. Hence it will be

= ∫eq 2 dy - ∫eq 1 dy with limts of 2 and -2

= ∫4 + 6y²dy - ∫7y²dy with limits 2 and -2

= [4y + 2y³ - 7/3 y³] with limits 2 and -2

In calculus, we can find the maximum and minimum value of any function or variable without on looking at the graph of the function.

Maxima will be the giant point on the curve within the given range and minima would be the minimum point on the curve. The combination of both is extrema.

Since 0 ≤ x^2 + y^2 ≤ 6, we have e^ (6*0) ≤ e^ (6(x^2 + y^2)) ≤ e^ (6*6) on D.

So, ∫∫ 1 dA ≤ ∫∫ e^ (6(x^2 + y^2)) dA ≤ ∫∫ e^36 dA

What is range and domain of a function?

Domain

The set of all possible values which qualify as inputs to a function is known as the domain of the function, or it can also be defined as the entire set of values possible for independent variables. The domain can be found in – the denominator of the fraction is not equal to zero and the digit under the square root bracket is positive. (In the case of a function with fraction values).

Range

The set of all the outputs of a function is known as the range of the function or after substituting the domain, the entire set of all values possible as outcomes of the dependent variable.

Now,

As inputs in the given relation are  {-3,-4,1,0}

and outputs are {1,-4,-3,8}.

Step-by-step explanation:

J:  y = 29 cm + (1 cm/mo)x

Z:  y = 12 cm + (2 cm/mo)x

29 cm + (1 cm/mo)x =  12 cm + (2 cm/mo)x

Solve for x to find how many months it will take for them to have the same length of hair:

29 cm - 12 cm = (2 cm/mo)x - (1 cm/mo)x

17 cm = (1 cm/mo)x

x = (17 cm) / (1 cm/mo) = 17 months

Plug this value for x (17 months) into the equations to find how long their hair will be:

J:  y = 29 cm + (1 cm/mo)(17 mo) = 46 cm

Z:  y = 12 cm + (2 cm/mo)(17 mo) = 46 cm
