Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).

weqwewe [10]

Vertex Form: y = a(x - h)^2 + k, with (h,k) as the vertex.

So firstly, plug the vertex into the vertex form: $y=a(x-1)^2-9$

Next, we first need to solve for a. Plug (0,-6) into the equation to solve for a as such:

$-6=a(0-1)^2-9\\-6=a(-1)^2-9\\-6=a-9\\3=a$

<u>Now we know that our equation is y = 3(x - 1)^2 - 9.</u>

Now to solve for the zeros (x-intercepts). Set y to 0 and add 9 to both sides of the equation: $9=3(x-1)^2$

Next, divide both sides by 3: $3=(x-1)^2$

Next, square root both sides: $\pm\sqrt{3}=x-1$

Next, add 1 to both sides: $1\pm\sqrt{3}=x\\2.73,-0.73=x$

<u>Your x-intercepts are (-0.73,0) and (2.73,0), or B.</u>

assume that 2000 births are randomly selected and 64 of the births are girls. use subjective judgment to describe the number of

tatuchka [14]

Total no. of births = 2000

Births of girls = 64

Birth% of girls

$= \frac{64}{2000} \times 100$

$= \frac{64}{20}$

$= \frac{6.4}{2}$

$= 3.2\%$

Hence, the number of girls are significantly low.

RESUELVE EL SIGUINTE PORBLEMA En la escuela "Soy Feliz porque soy diverso", hay 230 estudiantes en total. De estos, 35 son mujer

Tanzania [10]

Answer:

1) a. 195 are males

b. Males are the 85 %

2) 1/2

Step-by-step explanation:

Number of all the students: 230

35 are females

x are males

Then 35 + x = 230

x = 230 - 35 → 195

To determine the amount of males, from the total we apply the percent.

Percent = (Amount of males / Total of students) . 100

% = (195 / 230) . 100 = 85 %

2. In first place, Maria spent 13 for the book.

In second place, Maria spent 29 for the pencil box.

In total, she has spent 13+29 = 42

But, how many dolars have the grandpa gave to her?.

We can also apply percent and fractions, where:

(Book / Total) + (Pencil box/Total) + (What she did not spend/Total) = 1

13 + 29 + x = T

13/T + 29/T + x/T = 1, in conclussion x = 42

Total of money given = 84

Then, Maria has not spent the half of money→ 1/2
