The width in inches would be 12, because of the formula:
length x width = perimeter
so you would do it reverse!
perimeter/length = width
so, 144/12 = 12
I believe it’s the 3rd one
Answer: a) k >4.08
b) k = 4.08
c) k<4.08
Step-by-step explanation:
Since we have given that

a) For what values of k will the function have no zeros?
It mean it has no real zeroes i.e. Discriminant < 0
As we know that

Here, a =-3
b = 7
c = -k
So, it becomes,

b) For what values of k will the function have one zero?
It means it has one real root i.e equal roots.
So, in this case, D = 0
So, it becomes,

c) For what values of k will the function have two zeros?
It means it has two real roots.
In this case, D>0
So, it becomes,

Hence, a) k >4.08
b) k = 4.08
c) k<4.08
Answer:
y = 45/2
Step-by-step explanation:
Given:
y = 4x - 1 1/2
find the value of y when x=6
y = 4x - 1 1/2
Substitute x = 6 into the equation
y = 4(6) - 1 1/2
y = 24 - 1 1/2
** 1 1/2 = 3/2
y = 24 - 3/2
y = (48-3) / 2
y = 45/2
y = 45/2 when x = 6
V = 12 × 2 × 3 = 72 cm3
Hope this helps!
