Find the parabola through

Mathematics
1 answer:
Anni [7]3 years ago
3 0

Answer:

y = - 3x² - 24x - 60

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) = (- 4, - 12 ), thus

y = a(x + 4)² - 12

To calculate a substitute (- 7, - 39) into the equation

- 39 = a(- 7 + 4)² - 12 ( add 12 to both sides )

- 27 = 9a ( divide both sides by 9 )

- 3 = a

y = - 3(x + 4)² - 12 ← in vertex form

Expand (x + 4)²

y = - 3(x² + 8x + 16) - 12

   = - 3x² - 24x - 48 - 12

y = - 3x² - 24x - 60 ← in standard form

   = - 3(x²

MA_775_DIABLO [31]

Answer:

11 sq units

Step-by-step explanation:

(6×4) - ½(6×1 + 4×3 + 2×4)

= 24 - ½(6+12+8)

= 24 - ½(26)

= 24-13

= 11 sq units

Lowest common multiple of 12,18,56
Ira Lisetskai [31]

Step-by-step explanation:

12 = 2 × 2 × 3

18 = 2 × 3 × 3

56 = 2 ×2 × 2 × 7

Now

Common factor = 2

Remaining factor = 2 × 3 × 2 × 3 × 7

LCM = RF × CF

= 504

hence the lCM of 12 , 18 and 56 is 504...

KengaRu [80]

Answer:

8

Step-by-step explanation:

First find all factors of 72 and 64 and put them in their respective circles

The factors of 72: 1,2,3,4,6,8,9,12,18,24,36,72

The factors of 64: 1,2,4,8,16,32,64

Now find the factors that both numbers share.

Common factors: 1,2,4,8

The greatest common factor of 72 and 64 is 8.
