Step-by-step explanation:
x+3/x-2 - 1-x/x= 17/4
now let's put the expression on the upper side so it I'll be
x+3-x-2-1-x-x= 17×14
x-x-x-x+3-2-1= 238
+3-3= 238
= 238 answer
Answer:
Step-by-step explanation:
The discriminant is used to determine the number and nature of the zeros of a quadratic. If the discriminant is positive and a perfect square, there are 2 rational zeros; if the discriminant is positive and not a perfect square, there are 2 rational complex zeros; if the discriminant is 0, there is 1 rational root; if the discriminant is negative, there are no real roots.
The roots/solutions/zeros of a quadratic are where the graph goes through the x axis. Those are the real zeros, even if they don't fall exactly on a number like 1 or 2 or 3; they can fall on 1.32, 4.35, etc. They are still real. If the graph doesn't go through the x-axis at all, the zeros are imaginary because the discriminant was negative and you can't take the square root of a negative number. As you can see on our graph, the parabola never goes through the x-axis. Therefore, the zeros are imaginary because the discriminant was negative. Choice C. Get familiar with your discriminants and the nature of quadratic solutions. Your life will be much easier!

Answer:
Step-by-step explanation:
Given
Shape: Opening of a circular vase
Required
Determine the area
This opening implies a circle; hence the area will be calculated using area of a circle.
Solve for radius (r)
Substitute 6.75 for r in
