Step-by-step explanation:

The limit of the function as x approaches -2 is 20.To find the limit of the function (if it exists), we can substitute the given value into the function and simplify. Given function: f(x) = 4x² + 5x - 6x + 2

To find the limit as x approaches -2, we substitute -2 into the function:

f(-2) = 4(-2)² + 5(-2) - 6(-2) + 2
      = 4(4) - 10 + 12 + 2
      = 16 - 10 + 12 + 2
      = 20

Therefore, the limit of the function as x approaches -2 is 20.

To write a simpler function that agrees with the given function at all but one point, we can use a graphing utility. By plotting the given function and observing its behavior, we can create a simpler function that matches the original function except at one point.

However, without further information about the specific behavior of the given function, it is not possible to provide a more detailed explanation or a graph of the simpler function.

Problem Statement

The question asks us to plot the function:

And we were asked to state the x-, y- and z- intercepts.

Solution

The equation given is a 3-d equation as such when it is plotted, it gives a plane instead of a line for a normal linear 2-D equation.

We shall begin with the intercepts. To find the intercepts, we simply set x, y to zero to find the z-intercept, x, z to zero to find the y-intercept, and y, z to zero to find the x-intercept.

Let us proceed to find the intercepts:

The intercepts are:

x-intercept = 3

y-intercept = 2

z-intercept = -6

Graphically, we can observe these intercepts shown below:

The above figure shows the x and z intercepts.

The y-intercept is shown below:

The final image of the plane will look like this:

Answer:

\(\boxed {\boxed {\sf 3 \ pounds \ of \$4 \ candy}}\)

\(\boxed {\boxed {\sf 2.5 \ pounds \ of \$3.50 \ candy}}\)

Step-by-step explanation:

Let's create a system of equation. First, define the variables. One type of candy is x and the other is y.

Now, create 2 equations, one for the weight and one for the price.

\(x+y=5.5\)

\(4x+3.5y=20.75\)

The first equation represents the mixture of both types of candy that weighs 5.5 pounds. The second represents the prices of the candy and the mixture.

Next. solve for the variables using substitution. Isolate a variable in the first equation. Let's isolate y by subtracting x.

\(x-x+y=5.5-x\\y= 5.5-x\)

Now, we know what y is equal to, so we can substitute it into the second equation.

\(4x+ 3.5 (5.5-x)= 20.75\)

Distribute the 3.5. Multiply each term by 3.5

\(4x+(3.5*5.5)+(3.5*-x)\)

\(4x+19.25-3.5x= 20.75\)

Combine like terms on the right side.

\(0.5x+19.25=20.75\)

Subtract 19.25 from both sides of the equation to isolate the variable.

\(0.5x+19.25-19.25=20.75-19.25\)

\(0.5x= 1.5\)

Divide both sides by 0.5.

\(\frac {0.5x}{0.5}= \frac{1.5}{0.5}\\x=3\)

Now we can substitute x back into the first equation and solve for y.

\(x+y=5.5\\3+y=5.5\)

Subtract 3 from both sides to isolate the variable.

\(3-3+y=5.5-3\\y=2.5\)

There was 3 pounds of the $4 candy and 2.5 pounds of the $3.50 candy.

It will take 18.9 years for your investment to reach $1,500

From the question, we have the following parameters that can be used in our computation:

Initial deposit = 500 dollars

Rate of growth = 6% per year

The above implies that the growth follows an exponential path

An exponential function that represents a growth function is represented as

A(n) = a * (1 + r)ⁿ

Where

A(n) = value of investment after nth year

a = Initial deposit = 500

r = rate of growth = 6%

Substitute the known values in the above equation, so, we have the following representation

A(n) = 500 * (1 + 6%)ⁿ

Evaluate the sum

A(n) = 500 * 1.06ⁿ

When the investment is 1500 grams, we have

500 * 1.06ⁿ = 1500

Divide both sides by 500

1.06ⁿ = 3

So, we have

n = log(3)/log(1.06)

Evaluate

n = 18.9

Hence, the number of years is 18.9

For figure {0}, the number of tiles will be equal to 2.

Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function

Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Equation : A mathematical equation is used to equate two expressions.

Given is a graph as shown in the image.

The line passes through point -

(3, 8) and (4, 10)

So, the slope of the line will be -

m = (10 - 8)/(4 - 3)

m = 2

y = 2x + c

For the point (3, 8), we can write -

8 = 6 + c

c = 2

For figure {0}, the number of tiles will be equal to 2.

Therefore, for figure {0}, the number of tiles will be equal to 2.

Answer:

F'(-3) = 18

Step-by-step explanation:

Let g(x) = u and apply the chain rule

\(F(x)=f(g(x))=f(u)\\F'(x)=\frac{df(u)}{du}\)

\(\frac{du}{dx}=g'(x)\)

\(\frac{df(u)}{du}*\frac{du}{dx} = \frac{df(u)}{dx}\\F'(x)= \frac{df(u)}{du}*g'(x)\\F'(x)= f'(u)*g'(x)\\F'(x)= f'(g(x))*g'(x)\)

We now have all of the necessary definite values to solve the expression for x= -3:

\(F'(-3)= f'(g(-3))*g'(-3)\\F'(-3)= f'(-4)*6\\F'(-3)= 3*6\\F'(-3)= 18\)

Finally, we have that F'(-3)= 18.

Janet has 630 options to customize a car based on the given features.

How to solve the question?

To determine the number of ways Janet can customize a car, we need to multiply the number of choices she has for each feature. Therefore, the total number of ways Janet can customize a car can be calculated as:

10 car models x 7 exterior colors x 9 interior colors = 630

Thus, Janet has 630 options to customize a car based on the given features.

It's worth noting that this calculation assumes that each feature (car model, exterior color, and interior color) can be combined with any other feature, without any restrictions or dependencies. However, in reality, certain car models may not be available in certain exterior or interior colors, or there may be other restrictions on the customization options.

Additionally, there may be other features that Janet can customize, such as the type of engine, transmission, or other options. Therefore, the total number of customization options may be even greater than what we have calculated here.

In summary, based on the given information, Janet has 630 ways to customize a car, but in reality, the actual number of options may be more limited or varied depending on other factors.

To do this, we make use of the following representations:

From the question, we have the following equations

\(\mathbf{330A + 270B + 240C = 5850}\) ----the number of passengers

\(\mathbf{B + C = 2A}\) --- the relationship between the number of planes

\(\mathbf{250A + 200B + 240C =4950 }\) --- the budget

Make A the subject in \(\mathbf{B + C = 2A}\)

\(\mathbf{A=\frac{1}{2}(B + C)}\)

Substitute \(\mathbf{A=\frac{1}{2}(B + C)}\) in \(\mathbf{330A + 270B + 240C = 5850}\)

\(\mathbf{330 \times \frac{1}{2}(B + C) + 270B + 240C = 5850}\)

\(\mathbf{165B + 165C + 270B + 240C = 5850}\)

\(\mathbf{435B + 405C = 5850}\)

Divide through by 15

\(\mathbf{29B + 27C = 390}\)

Make C the subject

\(\mathbf{C = \frac{390 - 29B}{27}}\)

Substitute \(\mathbf{A=\frac{1}{2}(B + C)}\) in \(\mathbf{250A + 200B + 240C =4950 }\)

\(\mathbf{250 \times \frac{1}{2}(B + C) + 200B + 240C =4950 }\)

\(\mathbf{125B + 125C + 200B + 240C =4950 }\)

\(\mathbf{325B + 365C =4950 }\)

Divide through by 5

\(\mathbf{65B + 73C =990}\)

Substitute \(\mathbf{C = \frac{390 - 29B}{27}}\)

\(\mathbf{65B + 73\times\frac{390 - 29B}{27} =990}\)

Multiply through by 27

\(\mathbf{65B \times 27+ 73\times(390 - 29B) =990 \times 27}\)

\(\mathbf{1755B+ 28470 - 2117B =26730}\)

Collect like terms

\(\mathbf{1755B- 2117B =26730 - 28470}\)

\(\mathbf{-362B =-1740}\)

Solve for B

\(\mathbf{B =\frac{1740}{362}}\)

\(\mathbf{B =5}\) --- approximated

Substitute \(\mathbf{B =5}\) in \(\mathbf{C = \frac{390 - 29B}{27}}\)

\(\mathbf{C = \frac{390 - 29 \times 5}{27}}}\)

\(\mathbf{C = \frac{245}{27}}}\)

\(\mathbf{C = 9}\) --- approximated

Recall that: \(\mathbf{A=\frac{1}{2}(B + C)}\)

So, we have:

\(\mathbf{A = \frac{1}{2} \times (5 + 9)}\)

\(\mathbf{A = \frac{1}{2} \times 14}\)

\(\mathbf{A = 7}\)

Hence, you should order 7 Airbus A330-300s, 5 Boeing 767-300ERs and 9 Boeing Dreamliner 787-9s
