How many roots does y = x - 4x2 + 3x have?

Mathematics
1 answer:
amm18123 years ago
6 0

Answer:

2

Step-by-step explanation:

Since the polynomial is of degree 2, there will be 2 roots

To find the roots let y = 0, that is

x - 4x² + 3x = 0

4x - 4x² = 0 ← factor out 4x on the left side

4x(1 - x) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

1 - x = 0 ⇒ x = 1

The 2 roots are x = 0 and x = 1

In solving a jigsaw puzzle, a move consists of joining two clusters, including clusters of just one piece. What is the minimum n
ad-work [718]
Solution: As always, try to find a way of looking at the problem that makes the solution simple. In this problem, regardless of the current state of the puzzle, a move consists of combining two clusters into a single cluster. Therefore every move reduces the number of clusters by 1. Since we begin with 2000 clusters (the single pieces) and end with 1 cluster, we need \[2000-1=\boxed{1999}\] moves to complete the puzzle.

zmey [24]

Answer:

Option A

Step-by-step explanation:

Given the following question:
Mrs. Hernandez earns $35.60 an hour
One week she earned $854.40

To find the answer we divide 8,544 by 356

8544\div356=24
854.40\div35.60=24

Mrs. Hernandez worked "24 hours last week" by using the first options equation, we can find that answer.

Hope this helps.

Figure
ludmilkaskok [199]

Answer:

  • a rotation, followed by a translation
  • a translation, followed by two reflections

Step-by-step explanation:

The rigid motions are the transformations that produce congruent images.

There are three main kinds of rigid motions  :

  • Reflections : Flips a figure across a line of reflection.
  • Rotations : Rotates a figure about some degrees around a center point.
  • Translations : Moves figure on a plane about some distance in a certain direction.

But dilation is not a rigid transformation because it may change the size of the image. It is usually used to shrink or enlarge a shape.

So, the options having dilation and term "stretch" cannot produce congruent figures.

Hence, the correct options are :

  • a rotation, followed by a translation
  • a translation, followed by two reflections

Start with the number n = 54527. Divide n by 5 and round the result up to an integer. Keep repeating the division and rounding s
Elza [17]
Without rounding, I make it six. You could do it this way
54527/5^6 comes to a little over 3. That should be close enough. I'm going to check this by doing the divisions. I could let the computer do it, but I'd like to see if there's a pattern. There isn't and the correct answer is

6 <<<< divisions.
