Form quadratic functions given the following information:

nignag [31]

Answer:

$f(x)=-\frac{4}{7}(x-\sqrt{2}-3)(x+\sqrt{2}-3)$

$f(x)=-\frac{4}{7}(x^2-6x+7)$

Step-by-step explanation:

we have

f(3+√2 )=f(3− √2 )=0

x1=3+√2 and x2=3−√2 are the roots or x-intercepts of the quadratic equation

The quadratic equation in factored form is equal to

$f(x)=a(x-x1)(x-x2)$

substitute

$f(x)=a(x-(3+\sqrt{2}))(x-(3-\sqrt{2}))$

Find the value of the coefficient a

Remember that

f(1)=−8

For x=-1 -----> f(x)=-8

substitute

$-8=a(-1-(3+\sqrt{2}))(-1-(3-\sqrt{2}))$

solve for a

$-8=a(-4-\sqrt{2}))(-4+\sqrt{2}))$

apply difference of squares

$-8=a(14)$

$a=-\frac{4}{7}$

therefore

$f(x)=-\frac{4}{7}(x-(3+\sqrt{2}))(x-(3-\sqrt{2}))$

$f(x)=-\frac{4}{7}(x-\sqrt{2}-3)(x+\sqrt{2}-3)$

simplify

Applying distributive property

$f(x)=-\frac{4}{7}(x^2+\sqrt{2}x-3x-\sqrt{2}x-2+3\sqrt{2}-3x-3\sqrt{2}+9)$

$f(x)=-\frac{4}{7}(x^2-6x+7)$

Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three

irinina [24]

Answer:

7/3

Step-by-step explanation:

The distances have the ratio ...

(Q -P) = (2/3)(R -P)

Q = P +(2/3)R -(2/3)P = (2R +P)/3

Qy = (2Ry +Py)/3 = (2·0 +7)/3 = 7/3

A game involves rolling a number cube. You get one point if you roll an even number and negative one point if you roll an odd nu

Burka [1]

Answer: The sample space is {1, 2, 3, 4, 5, 6}.

The expected value for the game is 0.

The game is fair because the expected value is equal to 0.

Step-by-step explanation:

For rolling a dice the sample space = {1, 2, 3, 4, 5, 6}

As there are equal number of odd numbers as well as even numbers and we get one point if we roll an even number and negative one point if you roll an odd number, therefore, the expected value = 0

Therefore, the game is fair because the expected value is equal to 0.

Diana is buying plates and cups for a party. She wants the same number of each. Plates are sold in packs of eight and cups are s

Citrus2011 [14]

Answer:

What is the least number of plates and cups she can buy?

The least number of cups of plates and cups she can buy is 24

How many packs of plates?

3 packs of plates

How many packs of cups?

2 packs of cups

Step-by-step explanation:

What is the least number of plates and cups she can buy?

We solve this using the Lowest Common Multiple method

The L.C.M of 8 and 12

Multiples of 8: 8, 16, 24, 32, 40

Multiples of 12: 12, 24, 36, 48

Therefore,

LCM(8, 12) = 24

Hence, the least number of cups and plates she can buy is 24

How many packs of plates?

Plates are sold in packs of eight

Hence: 24 ÷ 8 = 3 packs of plates

How many packs of cups?

Cups are sold in packs of 12

Hence: 24 ÷ 12 = 2 packs of cups
