Answer:
p-q= -4
p=q-4
x^2 + px + q=0
=> x^2 + (q-4)x + q = 0
d= b^2-4ac
=(q-4)^2 - 4(1)(q)
= q^2 + 16 -8q - 4q
=q^2 -12q+16
given that D=16
q^2 -12q+16 = 16
=> q^2 -12q = 0
=> q^2 = 12q
=> q = 12q/q
=> q= 12
Therefore the value of q is 12 and the value of p is q-4 = 12-4= 8
Hope you understood............
Since the population is going to increase by a certain percentage, we have to add 
to the percentage to keep the original population.
Now, convert the percentage into a decimal. You can do this by moving the decimal place two places to the left.
Now, just multiply that by 
.
I hope this helps you
Volume of cone =1/3.pi.r^2.h
Volume of cone =1/3.3,14.60^2.150
Volume of cone =565.200
if 1,413cm^3 in one minute
565.200 cm^3 in ? minutes
?.1,413=565.200
?=400 minutes
1 hour =60 minutes
? hour =400 minutes
?=400/60
?=20/3 hour
∩ stands for the intersection of the two arrays think a venn diagram in this it would be three
<span>∪ stands for objects that belong to either set
</span>
It would be A <span>∪ B because that set shows objects from both sets
If i'm wrong sorry its been a while since I've practiced or learned it</span>
I think its thousend not sure tho
