5 0

Answer:

Step-by-step explanation:

The 5 parts of the ratio represents 10 boys.

Divide number of boys by 5 to find the value of one part of the ratio.

$\frac{10}{5}$ = 2 ← value of 1 part of the ratio

There are 6 parts of the ratio representing girls, thus

6 × 2 = 12 ← number of girls in the class

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4

lora16 [44]

Answer:

option A.) y-3 = 1/16 (x-2)^2

Step-by-step explanation:

we know that

If the axis of symmetry is parallel to the y-axis, then we have a vertical parabola

The equation of a vertical parabola is equal to

$4p(y-k)=(x-h)^{2}$

where

(h,k) is the vertex

In this problem we have

(h,k)=(2,3)

p=4

substitute

$4(4)(y-3)=4(4)(x-2)^{2}$

$16(y-3)=(x-2)^{2}$

$(y-3)=(1/16)(x-2)^{2}$
