Answer:
Step-by-step explanation:
first you have to see itis an arithmetic or geometric sequence.
then find common difference(for A.P) or common ratio (for G.P)
c.d .=an-an-1
c.r. =an/an-1
1.G.P.
2. A.P
3.G.P
3,5,25/3,125/9,...
c.r.=5/3
or (25/3)/5=25/(3*5)=5/3
or 125/9÷25/3=125/9×3/25=(125×3)/(9×25)=5/3
Answer:
70
Step-by-step explanation:
If g(x) =x^2 -1, then
f[g(5)] = 3*(5^2-1) -2 =72-2= 70
g(x)= 3k-2x²
g(-3)=-6 ____(1)
So, using (1),
-6 = g(-3)
=> -6 = 3k - 2(-3)²
=> -6 = 3k - 2(9)
=> -6 = 3k - 18
=> -6 +18 = 3k
=> 12 = 3k
=> 12/3 = k
=> 4 = k
Now, you can find g(n) for any number n, as now we know the value of k. Specify the value of x, if you want to know what is g(x).
The answer is: 75,000 mg
___________________________________________
Explanation:
___________________________________________
Note: 1000 mg = 1g ; is an exact value conversion;
___________________________________________
Convert 75 grams, or "75 g", into "milligrams" (mg).
___________________________________________
75 g * (1,000 mg/1g) = ? mg ?
___________________________________________
The "g" units cancel ; and we are left with:
___________________________________________
[(75 * 1,000 mg)] / (1) = (75 * 1,000 mg) = 75,000 mg
37/8 or 4 5/8
To make it easier, make both numbers into an improper fraction then subtract normally.
