<span>Just take the WHOLE NUMBER,(the 9) and multiply it by the denominator (the 2) and take the product (18) and add it to the numerator (1).....which equals 19, but it's all over the denominator...
so it's 19/2 </span>

Ms. White drives 8 miles each way, to and from her office. If she does this 5 days each week for 10 weeks, how many total miles
EastWind [94]
She will drive a total of 800 miles

8 times 2 because 8 miles each way would mean 16 miles in one day
five days a week so 16 times 5 = 80
for 10 weeks so 80 times 100 would mean a total of 800 miles

Consider the following functions. f1(x) = x, f2(x) = x2, f3(x) = 7x − 5x2 g(x) = c1f1(x) + c2f2(x) + c3f3(x) Solve for c1, c2, a

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

\Rightarrow c_1 =-7c_3                     \Rightarrow c_2=5c_3

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}
