14. Ashton has 3 less dollars than Cole. This relationship can be represented by an equation using

Please find the answer to this function! F(2)= 6x^4-10x^3+40x-50

steposvetlana [31]

Answer-

$f(2)= 6x^4-10x^3+40x-50=46$

Solution-

The given function is,

$\Rightarrow f(x)= 6x^4-10x^3+40x-50$

Now, we have to find the value of f(x) at x=2 i.e f(2), so putting x as 2 in the given function,

$\Rightarrow f(2)= 6(2)^4-10(2)^3+40(2)-50$

$\Rightarrow f(2)= (6\times 16)-(10\times 8)+(40\times 2)-50$

$\Rightarrow f(2)= 96-80+80-50$

$\Rightarrow f(2)= 96-50$

$\Rightarrow f(2)= 46$

Therefore, f(2) was found to be 46.

Sebastian was in a hotel lobby and took the elevator up 7 floors to his room. Then he took the elevator down 9 floors to the par

Aleks [24]

Answer:

Sebastian's error = 9 + (-7)

The correct expression for Sebastian's movement = 7 + (-9)

Step-by-step explanation:

Using the Lobby as a reference point

Sebastian's took 7 floors to his room

Hence, Lobby + 7 floors = Sebastian's room

Then, he took 9 floors down to the garage

Hence, Room - 9 floors = Garage

Therefore the total movement for Sebastian = Number of floors taken to his room + Number of floors taken to the garage

= 7 +(-9)

a) Sebastian's error was making the number of movements to his room negative, it is meant to be positive because he took the elevators UP

b) Sebastian's error was making the number of movements to the elevator positive, it is meant to be negative because he took the elevators DOWN to the garage

Hence, the correct expression = 7 +(-9)

How to solve this equation?

Novay_Z [31]

Answer:

x = √(28), or x = 5.292

Step-by-step explanation:

First you distribute the square to the values inside of the parentheses. so it ends up looking like this

5(x^2 - 25) - 9 = 6

add 9 to both sides

so its 5(x^2 - 25) = 15

Then distribute the multiplication of 5 to the contents within the parentheses

so it would be 5x^2 - 125 = 15

add 125 to both sides

you get 5x^2 = 140

divide by 5 on both sides

you get x^2=28

then, take the square root of both sides to reverse the square

√(x^2)=√(28)

and in the end you get x=5.292

but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
