Step-by-step explanation:
if (a+1/a) =4, find the value of (a cube +1/a cube)
Answer:
a=2+√3 or a=2−√3Step-by-step explanation:
Multiply all terms by a and cancel:aa+1=4a ∴ (Simplify both sides of the equation)
a2+1−4a=4a−4a ∴ (Subtract 4a from both sides)
a2−4a+1=0
For this equation: a=1, b=-4, c=1
1a2+−4a+1=0
a = −b ± √b2 − 4ac2a divided by 2a ⇒(Use quadratic formula with a=1, b=-4, c=1)
−(−4) ± √(−4) 2−4 (1) (1) /2 (1)
a=4±√12/2
a=2+√3 or a=2−√3
a=2+√3 or a=2−√3

Adsilla and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes. Adsila fills 11 boxes every hour. How many boxes does carlos fill every hour?
Answer:
[tex]Carlos = 16[/tex] per hour
Step-by-step explanation:
Given
[tex]Total = 108\ boxes[/tex]
[tex]Hours = 4[/tex]
[tex]Adsila = 11\ boxes\ per\ hour[/tex]
Required
Determine the unit rate of Carlos
First, we need to calculate the total boxes filled by Adsila.
If Adsila gets 11 in 1 hour.
Then Adsila get 4 * 11 in 4 hours
[tex]4 * 11 = 44\ boxes[/tex]
Next, we calculate number of boxes left.
[tex]Left = 108 - 44[/tex]
[tex]Left = 64[/tex]
This is yhe number of boxes filled by Carlos.
Recall that they worked for 4 hours each.
Hence:
[tex]Carlos = \frac{64}{4}[/tex]
[tex]Carlos = 16[/tex]
Anyone know how to solve this?
Answer:
[tex]-x^{4}+8x^{3}-17x^{2} +16\\\\=-x^{4}+4x^{3}+4x^{3}-16x^{2} -x^{2} +16\\\\=-x^{3}(x-4)+4x^{2}(x-4)-(x-4)(x+4)\\\\\\=(-x^{3}+4x^{2}-x-4)(x-4)\\\\ =>\frac{-x^{4}+8x^{3}-17x^{2} +16}{x-4}= (-x^{3}+4x^{2}-x-4)+\frac{0}{x-4}[/tex]

f(x)=-2x+3
g(x)=3x+3
find f(1-x) + g(1-x)
Answer:
-5x + 11
Step-by-step explanation:
All you're doing is substituting.
f(x)=-2x+3
f(1-x) = 2(1-x)+3
= 2 - 2x +3
= -2x + 5
g(x)=3x+3
g(1-x) = 3(1-x)+3
= 3 - 3x + 3
= -3x + 6
Now add them together and combine like terms:
f(1-x) + g(1-x)
-2x + 5 + -3x + 6
= -5x + 11
