Answer:

  y = -3x^2 +3x +6

Step-by-step explanation:

For roots p and q, the equation can be written as ...

  y = a(x -p)(x -q)

The value of 'a' must be determined so that the product apq is equal to the y-intercept. One could say that the formula is ...

  y = (y-intercept)/(pq)·(x -p)(x -q)

For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...

  y = 6/(2(-1))(x -2)(x +1)

  y = -3(x^2 -x -2) . . . . . simplifying a bit

  y = -3x^2 +3x +6

Answer:

76.4%

Step-by-step explanation:

Total area of flag:

LW = (37)(28) = 1036

Total area of red:

LW = (12 + 21)(12 + 12) = (33)(24) = 792

Percent of red:

792/1036 * 100% = 76.4%

Answer:

→(37×28) unit²=1036unit²

→[{2×(12×12)}+{2×(21×12)}]

=[{2×144}+{2×252}]

=[288+504]=792unit²

→(792/1036)×100=0.7645×100=76.45%

76.45% is the right answer.

Answer:

There are 12 red fish, 19 orange fish

Step-by-step explanation:

Let y rep amount of red fish

y + 7 = Amount of orange fish

y + y + 7 = 31

2y = 31 - 7

2y = 24

y = 12

Then

y + 7

12 + 7 = 19

Answer:

i got it right on my test it is 24 cubic feet

Step-by-step explanation:

Answer:

14 cm

Step-by-step explanation:

Given that:

Base, b of triangle = 5 cm

Height, H of triangle = 24 cm

Base of parallelogram, a = 30 cm

Area of triangle = 0.5 * bH

Area of parallelogram = a * h

Where, h = height of parallelogram

Area of parallelogram is 5 times the area of triangle ;

5 * 0.5 * 7 * 24 = 30 * h

420 = 30* h

h = 420 / 30

h = 14 cm

Answer:

24.58

Step-by-step explanation:

In the big triangle, you see two little triangle

one of the little triangle is a 45-45-90 triangle (the number represent the angle measures of the triangle)

this means that the legs are the triangle can be considered one, and the hypotenuse can be considered [tex]\sqrt{2}[/tex]

so in any 45-45-90 triangle, if you have a leg that is 4, then you know the other leg is also 4, and the hypotenuse would be 4 times [tex]\sqrt{2}[/tex] (aka 5.65)

the other triangle is a 30-60-90 triangle (the number represent the angle measures of the triangle)

this means that the smallest leg of the triangle can be considered one, and the other leg (the bigger one) can be considered 2, and the hypotenuse can be considered [tex]\sqrt{3}[/tex]

so the smallest leg here is 4, this means that the other leg would be 2 times 4 (aka 8)

and the hypotenuse would be 4 times [tex]\sqrt{3}[/tex] (aka 6.93)

so the sides that count to the perimeter of the given triangle would be 4, 5.65, 8, and 6.93

add those up and you get: 24.58

Answer:25 i’m confused

Step-by-step explanation:

The measure of the side BC of the triangle is BC = 28

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as A B C

Let the second triangle be represented as D E F

Now , the measure of side A D = measure of side D B

And , the measure of side A F = measure of side F C

The measure of side D F = 14

The measure of side D E = 10

The triangles ABC and DEF are similar triangles

From the Triangle segment theorem ,

D F = B C / 2

Substituting the values in the equation , we get

14 = B C / 2

Multiply by 2 on both sides of the equation , we get

The measure of side BC of triangle = 28

Hence , the measure of side B C is 28

Answer:

a) 5m

b) $26.25

Step-by-step explanation:

You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food.

a) Write an algebraic expression for the total amount of money contributed for money?

Let the total Amount of money each person contributed be = m

Since each person contributed the same amount , and there are 5 people(you and 4 friends)

The total amount of money contributed = 5 × m

= 5m

b) Evaluate you expression if each person get $5.25

From the answer in question a, we have algebraic expression = 5m

m = $5.25

Total cost = 5 × $5.25

= $26.25

Answer:

Cada hermana debe pagar $900.

A las dos hermanas que pagaron $1,200 se les reembolsarán $300.

Step-by-step explanation:

Dado que el costo mensual del servicio de internet cuesta $300 por mes, y que el mismo fue contratado por 9 meses por 3 hermanas que se comprometieron a pagarlo en partes iguales, el costo total del servicio será de $2,700 (300 x 9), y cada hermana deberá pagar $900 (2,700 / 3).

Así, si dos de las hermanas pagaron $1,200 cada una, la tercer hermana les deberá reembolsar $300 a cada una de ellas (1,200 - 300).
