Given that f(x)=4x3-12x2+10 and g(x)=x3 – 2x2 + 5x
The value of f(x)- g(x)= ax'+bx?+ cx+d. What are the values of the coefficients a,b,c,d?

Answers

Answer:

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Step-by-step explanation:

Given functions are:

[tex]f(x) = 4x^3-12x^2+10\\g(x) = x^3-2x^2+5x[/tex]

We have to find the value of f(x) - g(x). This means we have to subtract function g(x) from function f(x)

So,

[tex]f(x) - g(x) = (4x^3-12x^2+10)-(x^3-2x^2+5x)\\= 4x^3-12x^2+10-x^3+2x^2-5x[/tex]

Combining alike terms

[tex]= 4x^3-x^3-12x^2+2x^2-5x+10\\= 3x^3-10x^2-5x+10[/tex]

Now it was given that:

f(x)- g(x)= ax^3+bx^2+ cx+d

By comparing both we get

a = 3, b = -12, c = -5, d = 10

Hence,

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Describe how to use scientific notation to write a very large number. Give an example written in both standard form and scientific notation.

Answers

Answer:

Scientific notation is simply changing a number to x times 10^n, where x is no more than 10 and more than 1.

For example, 134 would be 1.34 times 10^2.

100 = 1.
101 = 10.
102 = 100.
103 = 1,000.
104 = 10,000. When we have large numbers, we can rewrite them as powers of ten. ...
Let's Review: Scientific notation is a great way to rewrite numbers with lots of zeros so that they are easier to work with.

——PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((———

Answers

Answer:

The slope is 0 because it is a straight line

Step-by-step explanation:

Answer:

undefined.

Step-by-step explanation:

You could be really formal and use the slope formula

The y values are both the same -- 4.

The x values are 3.5 and 6.5

Therefore  the slope is (6.5 - 3.5) / (4  -  4)

The denominator is 0

The slope is undefined because 3/0 is not very well behaved.

A horizontal line always gives an undefined amount.

Answers

Answer: option B

Step-by-step explanation:

-4, 1, 3

The roots of the polynomial equation x³ - 7x = 6x - 12 is given by the values x = -4 , 1 , 3

What is a polynomial?

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the polynomial equation be represented as A

Now , the value of A is

x³ - 7x = 6x - 12   be equation (1)

Now , it can be represented as 2 equations of the form

A = x³ - 7x   be equation (2)

And , B = 6x - 12    be equation (3)

On plotting the graphs of the two equations , we get

The point of intersection of the equations is at P ( -4 , -36 ) , Q ( 1 , -6 ) and R ( 3 , 6 )

Therefore , the x coordinates of the points are x = -4 , 1 , 3

Hence , the roots of the polynomial is x = -4 , 1 , 3

So all the possible solutions are:

[tex]\bold{204.4~and~217.6.}[/tex]

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Subtract 13.2 from both sides:

[tex]13.2-13.2=[/tex] Cancels Out[tex]217.6-13.2=204.4[/tex]

So now we know the real answer, but now we must find all the possible solutions.

(Means anything greater than or equal to 217.6 when you plug it into x + 13.2 ≥ 217.6.)

Numbers that are greater than 378:

  1.)  [tex]204.4+13.2=217.6[/tex] ≥ [tex]217.6[/tex]  (True)

  2.)  [tex]217.6+13.2=230.8[/tex] ≥ [tex]217.6[/tex]  (True)

  3.)  [tex]204.3+13.2=217.5[/tex] ≥ [tex]217.6[/tex]  (False)

  4.)  [tex]0+13.2=13.2[/tex] ≥ [tex]217.6[/tex]  (False)

  5.)  [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex]  (False)

  6.)  [tex]200.4+13.2=213.6[/tex] ≥ [tex]217.6[/tex]  (False)

  7.)  [tex]-200+13.2=-186.8[/tex] ≥ [tex]217.6[/tex]  (False)

  8.)  [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex] (False)

Now put all the numbers together to form the code.

Gabe bought five sacks of apples each sack weighed 12 lb he paid three for each pound of apples what was the total cost of all of the apples Gabe bought

Answers

Answer:

The cost of 12lbs of apples is $36.

Step-by-step explanation:

Lets Solve!

⟹ First we must define x and y.

 x is the lb's of apples and y is the cost.

⟹ Now lets form our equation.

[tex]3x = y[/tex]

[tex]x = 12[/tex]

⟹ Since gabe bought 12 pounds of apples x = 12.

⟹ Now substitute x for 12.

[tex]3x = y[/tex]

[tex]3(12)= y[/tex]

⟹ Now multiply.

[tex]36 = y[/tex]

The cost of 12lbs of apples is $36.
