HELP PLEASEE the product AB is:

Step-by-step explanation: The range of the function is the set of all its output values. To find the range of f(a) = 5 + 1/2a when the domain is (0, 4, 6), we can substitute these values into the function and see what the output is:

f(0) = 5 + 1/2 * 0 = 5

f(4) = 5 + 1/2 * 4 = 7

f(6) = 5 + 1/2 * 6 = 8

So the range of f(a) is the set of values {5, 7, 8}.

By 17.77 percent this stock price rises.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, In one day, the stock price for Warbeck's Coffee rose from $5 to $6 per share.

From the general formula of percentage:

Percentage = difference value/ total value * 100

In our case,

Difference value = 6-5

Difference value = 1

total value = 6

thus,

Percentage change = 1/6 * 100

percentage change = 17.77%
Therefore, By 17.77 percent this stock price rises.

Step-by-step explanation:

The value of the quadratic equation is A = ( 9x + 10 ) ( x - 2 )

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

A = 9x² - 8x - 20   be equation (1)

On simplifying the equation , we get

A = 9x² - 18x + 10x - 20

On factorizing the equation , we get

A = 9x ( x - 2 ) + 10 ( x - 2 )

Taking the common factors in the equation , we get

A = ( 9x + 10 ) ( x - 2 )

So , when A = 0

( 9x + 10 ) = 0

x = -10/9

And , when ( x - 2 ) = 0

x = 2

Hence , the quadratic equation is A = ( 9x + 10 ) ( x - 2 )

Step-by-step explanation:

Point (0,4) slope (3/4) form would be

y-4 = 3/4 ( x-0)     re-arrange to y = mx + b form

y = 3/4x + 4

a) The graph of the quadratic function that models this situation is given by the image presented at the end of the answer.

b) The zeros are given as follows: x = 30 and x = 50.

c) The function is defined as follows: y = 0.03x² - 2.4x + 45.

The quadratic function with roots x* and x** is given by the equation presented as follows:

y = a(x - x*)(x - x**)

The roots = zeros are the values of x for which the graph of the function crosses the x-axis, hence:

x* = 30, x* = 50.

Then the function is:

y = a(x - 30)(x - 50)

y = a(x² - 80x + 1500).

When x = 0, y = 45, hence the leading coefficient a is obtained as follows:

1500a = 45

a = 45/1500

a = 0.03.

Hence the definition of the function is given as follows:

y = 0.03(x² - 80x + 1500).

y = 0.03x² - 2.4x + 45.

Answer:

$773.55

Step-by-step explanation:

To find the total cost of the camera with the sales tax included, you need to calculate the amount of sales tax and add it to the listed price of the camera.

The sales tax rate is given as 9.75%. To convert this to a decimal, divide the percentage by 100: 9.75/100 = 0.0975

To find the amount of sales tax, multiply the listed price of the camera by the sales tax rate as a decimal: $704.95 x 0.0975 = $68.60

To find the total cost of the camera, add the amount of sales tax to the listed price: $704.95 + $68.60 = $773.55

So the total cost of the camera with the sales tax included is $773.55

The assumed line's and direction's parametric equation is x = 5 + t; y = -1; z = 3 -2t

How can the parametric equation be found?

The absence of points and lines renders the question insufficient.

I will therefore utilize the following presumptive parameters:

As the line traverses: (5, -1, 3)

The direction is  ~v = <1, 0, -2>

The parametric equation of the line is represented as:

r<x,y,z> = Line + t<direction>

This gives

r<x,y,z> = (5, -1, 3) + t<1, 0, -2>

Express the equation in terms of x, y and z

x = 5 + t * 1

y = -1 + 0 * t

z = 3 -2 * t

Solve the equations

x = 5 + t

y = -1

z = 3 -2t

The units of R'(7) are gallons/hour/hour, or equivalent gallons/hour is 6 = 0.15 gallons per hour and  2 R(t) dt using the average Riemann sum with four equal length partitions is 383.04 gallons.

(a)  R'(7), you can use the mean rate of change formula.

R'(7) ≈ [R(10) - R(4)] / [10 - 4]

With the data from the table it looks like this:

R(10) = 11.3 gallons per hour

R(4) = 10.4 gallons per hour

For this,

R'(7) ≈ (11.3 - 10.4) / 6 = 0.15 gallons per hour

The units of R'(7) are gallons/hour/hour, or equivalent gallons/hour squared.

(b) To approximate 2 R(t) dt using the average Riemann sum with four equal length partitions, we can use

Δt = (24 - 0) / 4 = 6

2 R(t) dt ≈ 2Δt [R(1.5Δt) + R(4.5Δt) + R(7.5Δt) + R(10.5Δt)]

With the data from the table it looks like this:

R(1.5Δt) = R(4.5) = 10.4 gallons/hour

R(4.5Δt) = R(10.5) = 11.3 gallons per hour

R(7.5Δt) = R(16.5) = 10.2 gallons/hour

R(10.5Δt) = R(22.5) = 9.6 gallons per hour

For this,

2 R(t) dt ≈ 2(6) [10.4 + 11.3 + 10.2 + 9.6] = 383.04 gallons
