Write the equation in vertex form: Vertex is (1.-3) and passes through the point (-1,5)

boyakko [2]

Answer:

y = 2(x - 1)² - 3

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

Here (h, k) = (1, - 3), thus

y = a(x - 1)² - 3

To find a substitute (- 1, 5) into the equation

5 = a(- 1 - 1)² - 3

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

8 = 4a ( divide both sides by 4 )

a = 2

Thus

y = 2(x - 1)² - 3 ← in vertex form

AnnZ [28]

Answer:

-4(9d-1)

Step-by-step explanation:

(6d-10d×3+3d×2)-(5d×3+3d-4)

(6d-30d+6d)-(15d+3d-4)

6d-30d+6d-15d-3d+4d

-36d+4

3. In New York, the Mega Ball jackpot lottery asks you to pick 5 numbers (integers) from 1 to 59 (the "upper

svlad2 [7]

Answer:

P = 0.000000028514

Step-by-step explanation:

First we are going to calculate the probability of correctly choosing exactly 4 of the winning numbers.

Remember that the probability of an event can be calculated thus:

$P = \frac{favourable - cases}{total -cases}$

The favorable cases resulting from choosing 4 numbers of the set of 5 winning numbers from the upper section.

The favorable cases can be calculated with a combinatorial thus:

$5C4 = \frac{5!}{(5-4)!4!} =5$

and the total cases are:

$59C5 = \frac{59!}{(59-5)!5!} = 5006386$

Then the probability is:

$P = \frac{5}{5006386} = 0.000000998$

and the probability of correctly choosing the Mega Ball number is:

$P = \frac{1}{35}$ = 0.0285714

And how both events are independent the probability of correctly choosing exactly 4 of the winning numbers and the Mega Ball number is:

P = (0.000000998)(0.0285714)

P = 0.000000028514

identify the number that does not belong with the other 3.Explain your reasoning. -10/2 , -13.4 , square root of 18 , 22.7 repea

tekilochka [14]

22.7 repeating does not belong with the other three numbers because it is the only repeating decimal in the data set.
