Write the coordinate point for the vertex of this parabola x^2=12y

sergeinik [125]

Answer:

(0,0)

Step-by-step explanation:

the x coordinate for the vertex is at the line of symmetry

ax^2 +bx+c

the line of symmetry is at h =-b/2a

x^2 =12y

divide by 12

1/12 x^2 = y

a = 1/12 b=0 c=0

h = 0/(2* 1/12)

h =0

to find the y coordinate, substitute x=0 back in

y = 1/12 * 0 = 0

the vertex is (0,0)

Answer:

Y = - 12.55X1 + 276.52

Step-by-step explanation:

Given the data:

Age of child :(X) : 4, 6, 10, 13, 14, 17

Time (seconds) (Y) : 230, 205, 132, 119, 108, 62

Using technology, the linear regression equation obtained using the data Given is :

Y = - 12.55X1 + 276.52

Where :

Slope = - 12.55

Intercept = 276.52

This also indicates that a negative slope is present and hence a negative relationship between age of Child and time in seconds.

Y varies directly as x. Y=42 when x=6. Find the value of y when x =15.

pentagon [3]

Answer:

y=120

Step-by-step explanation:

Y varies directly as x is written as

$y \alpha x$

introducing a constant

y=kx

from the question, when y=48, x=6

substitute it in the formula

48=6k

making k the subject by dividing through by 6

$\frac{48}{6} = \frac{6k}{6}$

k=48/6

k=8

put the value of k in the expression y=kx

y=8x

from the question,the value of y when x=15 is given by

y=8×15

y=120.
