Answer:
Use ellipses. Zero solutions at bottom
a(x-b)^2 + c(y-d)^2 + e = 0
Two equations with different constants.
Step-by-step explanation:
Egrav=mgh
m=mass
g=gravity
h=height
0.95*10*3.0=28.5
Egrav=28.5J
Answer:
17
Step-by-step explanation:
because 19 students for the other in total (you add the ones who study biology and the ones who study both, then you minus the group of students by 19)
I would have wished to see Venn Diagram, however I will try to answer this problem:
A={1,2,3,4}
B={1,2,5,6}
(A∩B) ={1,2}
The complement of (A∩B) is (A∩B)'
(A∩B)' = A'∪B' (De Morgan's law)
A' ={5,6} and B'={3,4}
A'∪B' = {5,6} ∪ {3,4}
A'∪B' = (A∩B)' = {3,4,5,6}
Hi there
To find the simple interest earned
Use this formula
I=prt
I interest earned?
P principle 30000
R interest rate 0.05
T time 15 years
So
I=30,000×0.05×15
I=22,500
Hope it helps
