HELP PLEASE

Mathematics
1 answer:
Paraphin [41]3 years ago
3 0

Answer:

x^4- x^3- 4x^2-3

Step-by-step explanation:

Given

f(x)= x^4- x^2+9

And

g(x)= x^(3 )+ 3x^2+12

We have to find

(f-g)(x)= ?

The operations on functions are as easy as the operations on numbers or polynomials.

We have to subtract the functions to find the above mentioned operation.

=(f-g)(x)=f(x)-g(x)

(f-g)(x)=[x^4- x^2+9]-[x^(3 )+ 3x^2+12]

The minus will change the signs of function g.

= x^4- x^2+9- x^(3 )- 3x^2-12

= x^4- x^3- x^2- 3x^2+9-12

=x^4- x^3- 4x^2-3

Hello There!

You would have to do work out 2 to the fourth power.
Also, 3 x 4.
The rules of powers are:
If you have to multiply, you add them
If you have to divide, you subtract them
If they are in brackets like this ^^, you multiply them.

Therefore, your answer is 16^{12}

Hope This Helps You!
Good Luck :)

PLEASE ANSWER THIS AND SHOW WORK. FIND THE SURFACE AREA FOR THE FIGURE BELOW
Varvara68 [4.7K]

Answer:

Total surface area of the given figure is 246.75 square mile.

Step-by-step explanation:

Surface Area of the given figure = Lateral surface area + Area of the base

Lateral surface area of the figure = Sum of the areas of 5 triangular surfaces

                                                        = 5(\frac{1}{2} )(\text{Base})(\text{Slant height})

                                                        = \frac{5}{2}(7)(9.3)

                                                        = 162.75 mi²

Surface area of the pentagonal base = 84 mi²

Total surface area of the figure = 162.75 + 84

                                                    = 246.75 mi²

Therefore, total surface area of the given figure is 246.75 square mile.

A farmer harvested 14,000kg of peanuts from an 8-acre farm. Which equation could be used to find the value of x, the expected ha
pickupchik [31]

Answer:

<h2>52500 kg</h2>

Step-by-step explanation:

Step one:

given data

mass of harvested peanuts = 14,000kg

size of land = 8-acre

Step two:

Required:

mass of harvested peanuts for a 30-acre land

let the mass be x

so, for 8-acre land the harvested mass is 14,000

hence for 30-acre land the harvested mass is x

cross multiply we have

8x=14,000*30

divide both sides by 8

x=420000/8

x=52500 kg
