Answer:
4/3−4√5+13√7
Step-by-step explanation:
So for whatever reason we don't like it when the radical is in the denominator so we're going to do a process called rationalization and get rid of it. We do this by multiplying both the numerator and denominator by the radical
So for the first part we multiply the numerator and denominator by 
which gives us 
we can then factor the 28 into sqrt(7,2,2) which simplifies to 
/28 So then we can simplify this and get 
We then can simplify the rest of these radicals and get 
and 
This means that so far we have the following:
We can add the like terms and simplify the fraction and get 4/3−4√5+13√7
Answer:
A = -10.5
Step-by-step explanation:
To find the value of "A", you can plug x = 2 and f(x) = 3 into the equation. This will allow you to simplify and find the value of "A".
f(x) = 4x³ + Ax² + 7x - 1 <---- Original equation
3 = 4(2)³ + A(2)² + 7(2) - 1 <---- Plug x = 2 and f(x) = 3 into equation
3 = 4(8) + A(4) + 14 - 1 <---- Solve 2³ and 2²
3 = 32 + A(4) + 14 - 1 <---- Multiply 4 and 8
3 = 45 + A(4) <---- Combine like terms
-42 = A(4) <---- Subtract 45 from both sides
-10.5 = A <---- Divide by 4
If A = -10.5, the final equation would look like this:
f(x) = 4x³ - 10.5x² + 7x - 1
From my knowledge of what an interquartile range is I have to say the answer to your question is 55.5.
