Answer:
x^6 + 2x^3 -2x^2 -8x + 4
Step-by-step explanation:
Okay, so we need to multiply f and g.
Since you said asap, I won't do the long explanation...
x3 -4x 2
x2 x6 -4x2 2x2
2 2x3 -8x 4
x^6 + 2x^3 -2x^2 -8x + 4
I'm pretty sure that this is how it goes
If ƒ(x ) = x^2 + 1, find ƒ(a + 1).
x=(a+1) so u replace x to get this:
f(a+1) = (a+1)^2+1
If you square "a" it just becomes a^2 and "1" squared is just "1"
1+1=2
Answer: a^2+2a+2
So first let’s simplify each term by adding the numbers together. Now we have 10/5 + 9/3. We are still working with each term individually, so next let’s simplify by dividing. 10/5 is 5, and 9/3 is 3, so now we have 5+3 which equals 8. Hope this helps!
Answer:
The probability is 406/625
Step-by-step explanation:
If they are of different materials, we have the following combinations of selection;
(gold and silver) or ( silver and titanium) or (gold and titanium )
The number of earrings present is 13 + 10 + 12 = 25
Probability of selecting a gold earring is 13/25
Probability of a silver is 10/25
Probability of a titanium is 12/25
Substituting these into the probabilities, we have;
(13/25 * 10/25) + (10/25 * 12/25) + (13/25 * 12/25)
= 130/625 + 120/625 + 156/625 = 406/625
