Answer:
The quadratic function is f(x) = (x − 2) (x − 4)
Step-by-step explanation:
Given a vertex with an x-coordinate of 3. we have to write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two distinct roots.
As the vertex lies on the axis of symmetry, so the axis of symmetry is x = 3. Now we have to take two x-intercepts that are equal distance from the axis of symmetry i.e from point of vertex and we can use these x-intercepts to write factors of the function by subtracting from x.
we take 2 and 4 ∴ factors becomes (x-2) and (x-4)
Hence, the quadratic function is
f(x) = (x − 2) (x − 4)
To solve this, you would multiply 2 3/8 by 1/4, which is the same thing as dividing by 4. Without a calculator to divide, we must first turn 2 3/8 into an improper fraction. To do this we multiply the whole number of 2 by the denominator of 8 and add the product of 16 to the numerator of 3, which would get us with 19/8 x 1/4. The product would be 19/32, the pounds that each serving weighs.

Answer:
sqrt(2)
Step-by-step explanation:
bd=ab/2=2
=> bc=qrt(bd^2+dc^2)=sqrt(4+16)=2sqrt(5)
