Find the other x-intercept for the parabola defined by this equation y=2x2+3-2

ASHA 777 [7]

Answer:

( $\frac{1}{2}$ , 0 )

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

2x² + 3x - 2 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 2 = - 4 and sum = + 3

The factors are + 4 and - 1

Use these factors to split the x- term

2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term

(x + 2)(2x - 1) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = $\frac{1}{2}$

The x- intercepts are (- 2, 0 ), ( $\frac{1}{2}$ , 0 )

Help me with this question

kaheart [24]

First combine like terms and put the expression in standard form. This expression is now in simplest form and cannot be simplified anymore.
3a + 10ab - 7a^2b - 10ab^2 + 12ab - (-4) + (-a^2b) - 5a
-10ab^2 - 8a^2b -2a + 24ab - (-4)

Hope this helps

A political action committee is interested in the proportion of all registered voters who will vote "Yes" on a measure to expand

kirza4 [7]

Answer: parameter: The proportion of registered voters who will vote Yes on the measure.

Sample: The 1000 registered voters who participated in the study.

Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.

Variable: Yes or No for each registered voter

Population: All registered voters in the US

Data: The list of Yes and No answers that were given by the 1000 participants in the study.

Step-by-step explanation:

Definitions of the given terms:

Population: Large groups of individuals having similar characteristics as per the researcher's point of view.

Sample: It is a subset of the population used to represent it.
Parameter: Measure of particular characteristics in the population.
Statistic: Measure of particular characteristics in the sample.
Variable: Characteristics that vary.
Data: A collected information facts and statistics.

Hence, by using the above definitions, we have

Parameter: The proportion of registered voters who will vote Yes on the measure.
Sample: The 1000 registered voters who participated in the study.
Statistic: The proportion of the 1000 registered voters that were surveyed who will vote Yes on the measure.
Variable: Yes or No for each registered voter.
Population: All registered voters in the US.
Data: The list of Yes and No answers that were given by the 1000 participants in the study.

In Exercises 3-6, copy the conditional statement. Underline the hypothesis and circle the conclusion. 3. If a polygon is a penta

vredina [299]

Conditional statement also known an if-then statement is of the form;

$\text{If p},\text{ then q}$

where;

p = hypothesis

q = conclusion

Hypothesis is the group of words that comes after the word "IF" in a conditional statement.

While The Conclusion is the group of words that comes after the word "Then" in a conditional statement.

With this explanation, let us proceed to answer the question.

3. If a polygon is a pentagon, then it has five sides.

Hypothesis = a polygon is a pentagon

Conclusion = it has five sides.

4. If two lines form vertical angles, then they intersect.

Hypothesis = two lines form vertical angles

Conclusion = they intersect.

5. If you run, then you are fast

Hypothesis = you run

Conclusion = you are fast

6. If you like math, then you like science.

Hypothesis = you like math

Conclusion = you like science.
