Answer:

a - 3

b - 5

c  -  -2

Step-by-step explanation:

The quadradic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

When:

ax^2+bx+c

This is the standard form of a quadradic equation.

We have the equation:

3x^2+5x-2\\\\

Recall the standard form.

'3' is in a's place, '5' is in b's place, and '-2' is in c's place.

Hope this helps you.

Can someone help me figure out number 3? message me for the word bank
irga5000 [103]

The respective reasons, chosen from the given word bank, for each of the statements in the proof are given as follows:

1. Given

2. Definition of Congruence

3. Segment Addition Postulate

4. Substitution Property

5. Substitution Property

6. Transitive Property

7. Definition of Congruence

Given data: \overline{PQ}=\overline{TQ}, \overline{UQ}=\overline{QS}

To provide: The reasons for each statement leading to the proof of \overline{PS}=\overline{TU}

The given word bank is:

  • Transitive Property
  • Substitution Property
  • Definition of Congruence
  • Substitution Property
  • Definition of Congruence
  • Segment Addition Postulate
  • Given

The explanations for each word in the word bank is as follows:

Transitive Property: If x=y and y=z, then x=z

Substitution Property: If two quantities are equal, then one quantity can be replaced in a statement involving the other quantity.

Definition of Congruence: Two line segments are defined to be congruent if their lengths are equal.

Segment Addition Postulate: Adding two line segments, if they are part of the same line, results in the line segment containing both the line segments.

Given: Listing the given conditions in any mathematical problem.

Now, the statements leading up to the required proof and their reasons are given as follows:

Statement 1. \overline{PQ}=\overline{TQ}, \overline{UQ}=\overline{QS}

Reason 1. Given

Explanation: Listing the given conditions

Statement 2. PQ=TQ, UQ=QS

Reason 2. Definition of Congruence

Explanation: Statement 2 directly follows from Statement 1 by the definition of congruence of line segments

Statement 3. PQ+QS=PS, TQ+QU=TU

Reason 3. Segment Addition Postulate

Explanation: Two line segments are added to get a line segment containing both segments

Statement 4. TQ+QS=PS

Reason 4. Substitution Property

Explanation: The first part of Statement 2. is substituted into the first part of Statement 3

Statement 5. TQ+QS=TU

Reason 5. Substitution Property

Explanation: The second part of Statement 2 is substituted into the second part of Statement 3

Statement 6. PS=TU

Reason 6. Transitive Property

Explanation: The Statements 4 and 5 constitute the condition and Statement 6 constitutes the result of applying transitive property

Statement 7. \overline{PS}=\overline{TU}

Reason 7. Definition of Congruence

Explanation: The Statement 6 implies the equality of two line segments. Applying the definition of congruence, it implies the congruence of those line segments

These are the respective reasons, chosen from the given word bank, for each of the statements in the proof.

school teacher and needs 22 pieces of wood, 3 over 8 ft long, for a class project. If he has a 9-ft board from which to cut the
tiny-mole [99]

Answer:

Yes, he will have enough 3 over 8 ft pieces for his class.

Step-by-step explanation:

Given:

Number of wood required = 22

Length of each wood, l=\frac{3}{8}\textrm{ ft}

Total length of the board, L=9\textrm{ ft}

Therefore, the number of woods that can be made using the given board is given as:

\textrm{Number of woods made}=\frac{\textrm{Total length of board}}{\textrm{Length of each wood}}\\\textrm{Number of woods made}=\frac{L}{l}=\frac{9}{\frac{3}{8}}=9\times \frac{8}{3}=\frac{72}{3}=24

So, he can make 24 woods of length \frac{3}{8}\textrm{ ft} using the 9 ft board. But he has to make only 22 pieces.

Therefore, he has enough of the wood to make the required number of pieces.
