Answer:
9x^2+4x+5
Step-by-step explanation:
f ( x ) = 5x^2 - 2x + 6
g ( x ) = 4x^2 + 6x - 1,
Add the functions together
f(x)+ g(x) = 5x^2 - 2x + 6 + 4x^2 + 6x - 1
Combine like terms
=9x^2+4x+5
To turn a mixed number into an improper fraction, you have to multiply the denominator with the whole number and add the numerator to the result. The denominator doesn't change.
The denominator is 4. The whole number is 2. Multiply:
The numerator is 3. Add that to the product of the denominator and whole number.
The denominator stays the same. The denominator is 4. Make it as a fraction(improper).
Your answer is 
The relevant formula that we can use in this situation is:
v = v0 + at
where v is the final velocity, v0 is the initial velocity
= 20 km/hr, a is acceleration at 3.4 m/s^2 and t is time at 20 seconds
First convert v0 to m/s, v0 = 5.56 m/s
v = 5.56 m/s + 3.4 m/s^2 * 20 s
v = 73.56 m/s
Then convert back to km/hr:
<span>v = 264.82 km/hr</span>
Answer:
25%
Step-by-step explanation:
customer paid = 9492
less vat (13%) .net =8400
discount =16%==marked price = 8400X 100/84==10,000
profit on sale =5% . cost :=8000
% on cost (2000/ 8000) X100 =25%
