The function f(x) = x2 + 10x - 3 writers in vertex form is f(x) = (x + 5)2 - 28. What are the coordinates of the vertex?

andrey2020 [161]

General formula of the parabola in vertex form is

f(x) =(x-h)² +k, where (h,k) is a vertex of the parabola.

f(x) = (x + 5)²- 28

h= -5, k = -28,

so (-5, -28) is a vertex of the given parabola.

Answer is A.

Saul is playing a game using a wheel divided

Art [367]

Using the binomial distribution, it is found that there is a 0.25 = 25% probability he will land on A on the first spin and A and the second.

For each spin, there are only two possible outcomes, either it lands on Sector A, or it does not. The results of each spin are independent, hence, the binomial distribution is used to solve this question.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem, we have that:

The sectors are equal, which means that it is equally as likely to land on each, hence $p = \frac{1}{2} = 0.5$ .

Saul will spin the wheel twice, hence $n = 2$ .

The probability that both land on A is P(X = 2), hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{2,2}.(0.5)^{2}.(0.5)^{0} = 0.25$

0.25 = 25% probability he will land on A on the first spin and A and the second.

Danny keeps five cards with the picture of a cat and six cards with the picture of a dog on a table face down, so the pictures a

Trava [24]

Total cards with cat = 5
Total cards with dog = 6
Total cards = 5 + 6 = 11

He removed a card with dog.
Total cards with dog = 6 - 1 = 5
Total number of cards = 11 - 1 = 10

P(dog) = 5/10 (Answer C)

F(x) = -1/3x find the average rate of change of f from -2 to 2

Bas_tet [7]

Average rate=(change in y)/(change in x)

if f(x)=-x/3

r=( f(2)-f(-2) )/(2--2)

r=(-2/3-2/3)/(2+2)

r=(-4/3)/4

r=-4/12

r=-1/3

For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.
