You can simply expand the factorised form out:
y = 14x² - 21x + 10x - 15
y = 14x² -11x -15

Answer:

The trinomial is 14x^{2}-11x - 15

Step-by-step explanation:

We need to find the trinomial which has the factors  (7x + 5)(2x - 3)

To find the trinomial , we need to multiply the factors

(7x + 5)(2x - 3)

multiply term wise,

14x^{2}-21x +10x - 15

14x^{2}-11x - 15

What is the perimeter of a square which has the same area as a circle with circumference of 4π?
enot [183]

Answer:

perimeter = 8\sqrt{\pi }

Step-by-step explanation:

We require to calculate the area (A) of the circle

A = πr² ← r is the radius

circumference = 4π = 2πr, hence

2πr = 4π ( divide both sides by 2π )

r = 2, hence

A = π × 4 = 4π

The area of the square is therefore 4π and area = s² ← s is the side length

s² = 4π ( take the square root of both sides )

s = \sqrt{4\pi } = 2\sqrt{\pi }, hence

perimeter = 4 × 2\sqrt{\pi } = 8\sqrt{\pi }

A.

ratio 1 to 1

alright
find the distance between the x values and the y values and seperate each into that ratio
1:1
A to B is (6,12) to (15,-4)
disatnce from 6 to 15 is 9, ratio would be 4.5:4.5=1:1
distance from 12 to -4 is 16, ratio would be 8:8=1:1
so the point would be (4.5,8)




b.
5:2
5+2=7
alright
A to C
(6,12) to (20,12)
distance from 6 to 20 is 14, 14/7=2, 2 times 5=10
distance from 12 to 12=0, so same coordinate
the point is (10,12)


c.
2+3=5

C to B
C is (20,12) and B is (15,-4)
distance from 20 to 15 is 5, so 2 is the x value
distance from 12 to -4 is 16, 16/5 times 2=32/5
the point is (2,32/5)

The equation of the parabola is:

y = 24x^2

---------------------------

The <em>equation </em>of a parabola of vertex (h,k) and focus (0,f) is given by:

y = 4p(x - h)^2 + k^2

  • Vertex at the origin means that h = 0, k = 0.
  • Focus (0,6) means that p = 6

Thus, the equation of the parabola is:

y = 4p(x - h)^2 + k^2

y = 4(6)(x - 0)^2 + 0^2

y = 24x^2
