write the equation of the parabola and a vertex form and standard form given the following information

beks73 [17]

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

(9)

Here (h, k) = (3, - 2), thus

y = a(x - 3)² - 2

To find a substitute (2, 3) into the equation

3 = a(2 - 3)² - 2 ( add 2 to both sides )

5 = a(- 1)² = a , then

y = 5(x - 3)² - 2 ← in vertex form

y = 5(x² - 6x + 9) - 2

= 5x² - 30x + 45 - 2

y = 5x² - 30x + 43 ← in standard form

(10)

Here (h, k) = (2, - 5), thus

y = a(x - 2)² - 5

To find a substitute (5, 4) into the equation

4 = a(5 - 2)² - 5 ( add 5 to both sides )

9 = a(- 3)² = 9a ( divide both sides by 9 )

a = 1

y = (x - 2)² - 5 ← in vertex form

y = x² - 4x + 4 - 5

y = x² - 4x - 1 ← in standard form

A researcher is interested in knowing whether responses to lowering the legal age for drinking alcohol varies by gender. Which s

likoan [24]

The statistical test that would be most appropriate determine the answer the researcher is interest in knowing is a chi-square test.

<h3>What is a chi-square test?</h3>

A chi-square test is a statistical test used to test the relationship between categorical variables. It is used to determine the difference between the expected data and the observed data is due to chance.

Chi squared = $\frac{(O_{i} - E_{i} )^{2} }{E_{i} }$

Where:

$O_{i}$ = observed value
$E_{i}$ = expected value.

The researcher is interested in knowing if the response to lowering the legal age for drinking alochol (observed value)) varies by gender (expected value). Thus, a chi-square test would be used.

F(x)=x3 −4x even odd or neither

Dennis_Churaev [7]

The answer is neither.

Let's take an odd number and substitute.

f(3) = 3³ - 4(3)
f(3) = 27 - 12
f(3) = 15 (odd)

Now, let's take an even number.

f(4) = 4³ - 4(4)
f(4) = 64 - 16
f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.

PilotLPTM [1.2K]

to find midpoint add the 2 x numbers and divide by 2

and add the 2 y numbers and divide by 2

X = -1 + 3 = 2, 2/2 =1

Y = 2 +4 = 6, 6/2 = 3

coordinate is (1,3)
