Find the difference:

1400 - 1250 = 150

Divide the difference by the starting value:

150 / 1250 = 0.12

Multiply by 100:

0.12 x 100 = 12% increase.

F(x)=25x^2-10x+1 what is the the value of the discriminant of f ​
Elanso [62]

Answer:

0

Step-by-step explanation:

Quadratic equation

x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}

The discriminant is the part of the quadratic formula within the square root symbol: {b^{2}-4*a*c}.  The discriminant indicates if there are two solutions, one solution, or none.

The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.

So, a positive discriminant tell us that the quadratic has two different real solutions.

A discriminant of zero tell us that the quadratic has two real and equal solutions.

And a negative discriminant tell us that none of the solutions are real numbers.

In this case: 25x^2-10x+1=0

We can see that

a= 25    b=-10   c=1

Using:  {b^{2}-4*a*c}

We have  -10^{2}-4* 25*1 =100-100=0

the answer is zero, so the quadratic has two real and equal solutions

irina [24]

Answer:

132 in^2 but DOUBLE CHECK MY WORK!!!!

Step-by-step explanation:

Break it down into parts ok. So I see a 10x10 square, two 2x4 right triangles and a 4x6 rectangle.

10x10 is 100 in

1/2(2*4) = 4 x 2 = 8 in

6x4 = 24 in

add them together to get 132 in^2
