Answer:
Therefore the solution is = k{-7,5,1} where k ∈R
Step-by-step explanation:
Given that,
f₁(x) =x
f₂(x)= x²
f₃(x)= 7x - 5x²
Also,
g(x) = c₁f₁(x)+c₂f₂(x)+c₃f₃(x)
Putting the values of f₁(x), f₂(x) and f₃(x).
g(x) = c₁.x+c₂x²+c₃(7x-5x²)
Given condition that g(x)= 0
∴ c₁.x+c₂x²+c₃(7x-5x²)=0
⇒(c₁+7c₃)x +(c₂-5c₃)x² = 0
Comparing the coefficients of x and x²
∴c₁+7c₃=0 and c₂-5c₃ =0
Let c₃= k [k∈R]
Then c₁ = -7k and c₂=5k
Therefore the solution is = { c₁,c₂,c₃}
= {-7k, 5k, k}
=k{-7,5,1}
The order of magnitude is the same thing as saying the scientific notation which is 4x10 to the power of six. The important thing about scientific notation is that there has to be a number only in the tens place but nothing in the hundreds and thousands.
692.08 : 21.1
Divide both sides by 21.1
32.8 :1
32.8ft per second
Hope this helps :)
Answer:
Step-by-step explanation:
<u>See steps below, solving for x:</u>
- x^(p/q) = a
- log x^(p/q) = log a
- p/q log x = log a
- log x = q/p log a
- log x = log a^(q/p)
- x = a^(q/p)
Answer:
-4
Step-by-step explanation:
8 - 2ab
8 - (2 * 2 * 3)
8 - 12
= -4
