Answer:
y= -4x^2 + 15x - 14
Step-by-step explanation:
A parabola is always in the form y = ax^2 + bx + c.
Substitute each point to produce different equations:
-14 = 0a + 0b + c = c
so c = -14
-3 = a1^2 + b1 + c = a + b - 14
so a + b = 11
0 = a2^2 + b2 + c = 4a + 2b -14 = 0
so 4a + 2b = 14
if we double a + b = 11 we get 2a + 2b = 22
Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15
We don't need to use the (3,5) points as we have all the information we need.

Answer:
36
Step-by-step explanation:
add the total that signed up for chemistry with the total that signed up for english which would be 20+16=36
Area of trapezium=384 square cm
Ratio of parallel sides=
Distance between parallel sides=h=12 cm
B. 84
The scale factor is 1/12 which means to get back to the actual height, you would multiply 7x12
