Discrimination of Y= -4x^2+ 2x+1

Mathematics
1 answer:
Taya2010 [7]4 years ago
5 0

Answer:

20

Step-by-step explanation:

I assume you mean discriminant.

For a quadratic y = ax² + bx + c, the discriminant is b² − 4ac.

Here, a = -4, b = 2, and c = 1.  So the discriminant is:

(2)² − 4(-4)(1) = 20

What represent the relationship between the total mass of a crate
sineoko [7]

9514 1404 393

Answer:

  (a)  M = 0.25n +100

Step-by-step explanation:

The distance between the dots on the graph is a rise of 1 grid square and a run of 2 grid squares. If we extend the sequence of dots to the left, we expect to place one at (0, 100). That is, the y-intercept of this function is 100 (eliminates choices C and D).

The rise of 1 grid square represents 25 kg, and the run of 2 grid squares represents 100 CDs. Then the slope of the function (rate of change) is ...

  slope = rise/run = 25/100 kg/CD = 0.25

Then the equation describing the points on the graph will be ...

  M = 0.25n +100

Help me pls ill give extra points
olga55 [171]

Answer:

y = x + 1

Step-by-step explanation:

We are using the points (0, 1) and (6, 7). First, use these points to find the slope.

m = y₁ - y₂/x₁ - x₂

⇒ m = 7 - 1/6 - 0

⇒ m = 6/6

⇒ m = 1

Now that we know the slope is one, enter the values into the point-slope form equation. I'll use (0, 1) in this instance.

y - y₁ = m(x - x₁)

⇒ y - 1 = 1(x - 0)

⇒ y - 1 = x

⇒ y = x + 1

Therefore, the equation is y = x + 1.
