Answer:

number of boys = 15

Step-by-step explanation:

The ratio of boys to girls is 5 : 7

Sum of the ratio is 12

The total students in the class is 36 students which include girls and boys.

since the ratio of boys to girls is known the number of boys and the number of girls can be computed.

Total student = 36

number of boys = 5/12 × 36

number of boys = 5 × 3

number of boys = 15

The number of girls = 36 - 15 = 21

if the vertex of a parabola is (-4,6) and another point on the curve is (-3,14), what is the coefficient of the squared expressi

Softa [21]

Answer:

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, 6 ), thus

y = a(x + 4)² + 6

To find a substitute (- 3, 14) into the equation

14 = a(- 3 + 4)² + 6 ( subtract 6 from both sides )

8 = a

Thus the coefficient of the x² term is a = 8

2 servings because one serving is 4%, so you would need would need to double that, or multiply it by two.
