Answer:
Step-by-step explanation:
Expand the brackets.
Multiply.
x = 1.
y = k(x + 3)
When x = 3 y = 12 so
12 = k(3 + 3)
6k = 12
k = 2.
So the relation is y = 2(x + 3)
When y is 8:
8 = 2(x + 3)
2x = 8 - 2*3 = 2
volume(V)=147cm^3
also,
v=1/3×3.14×7^2×h
or, 147×3=3.14×49×h
or, (441)/(3.14×49)=h
or, h=2.87cm
false
Although I will not give an explanation, your answer is...
a = -6
