30 ft^3. If the area is 10 the the length is 5 and width is 2. If the height is 3 then it is 3 x 5 x 2 = 30ft^3
I hope this helps you
3x^2+2x+7x^3+10x^2+6x+9
7x^3+13x^2+8x+9
Answer:
B. As x approaches negative infinity f(x) approaches positive infinity
Step-by-step explanation:
The given absolute value function is
.
This function has its vertex at (7,-7) and opens upwards.
That means it has a V-shape.
As the values of x grows bigger and bigger negatively or positively, the function f(x) approaches positive infinity.
In other words;
As x approaches positive infinity f(x) approaches positive infinity
As x approaches negative infinity f(x) approaches positive infinity
The correct choice is B.
In each let y = f(x) and rearrange making x the subject
(7)
y = 3x + 9 ( subtract 9 from both sides )
3x = y - 9 ( divide both sides by 3 )
x = 
change y back into terms of x
(x) = 
(8)
y = 5x - 2
5x = y + 2 ( divide both sides by 5 )
x = 
(x) = 
(9)
y = - x + 2
x = 2 - y
(x) = 2 - x
(10)
y = - 4x + 3
4x = 3 - y ( divide both sides by 4 )
x = 
(x) = 
(11)
y = 0.5x - 2
0.5x = y + 2 ( divide both sides by 0.5 )
x = 2(y + 2)
(x) = 2x + 4
(12)
y = - 0.25x + 6
0.25x = 6 - y ( divide both sides by 0.25 )
x = 4(6 - y )
(x) = 24 - 4x
Answer:
y = -2x^2 - 8x + 0
Step-by-step explanation:
By "standard form," I assume you mean "y = ax^2 + bx + c."
Your f(x)= -2x^2-8x has no constant term. But that's OK!
In standard form, then, you have y = -2x^2 - 8x + 0, or just y = -2x^2 - 8x.
Recognizing that this is a quadratic function, we can write:
a = -2, b = -8 and c = 0.
If this isn't the "standard form" that you had in mind, please share your version of "standard form."
