Answer:
Step-by-step explanation:
Answer:
3.29 s
Step-by-step explanation:
We are given that
Height of building=240
Initial velocity=20ft/s
The height of the ball after t seconds is given by
When the ball strike the ground then
h(t)=0
Quadratic formula:
Using the quadratic formula
Time cannot be negative .Therefore,
t=3.29 s
Answer:
Option h: 16h
Step-by-step explanation:
To get the answer to the question divide 480 by 30 to get the rate which is 16. So the answer would be H
(1 point) Consider the universal set U={1,2,3,4,5,6,7,8,9,10}, define the set A be the even numbers, the set B be the odd number

Answer:
a) AUC = {2,4,6,8,10}
b) BnC = {}
c) AnB = {}
d) B-C = B = {1,3,5,7,9}
Step-by-step explanation:
The set A is the even numbers, those that are divisible by two.
So A = {2,4,6,8,10}
B is the odd numbe.rs. An odd number is a number that is not divisible by two.
So B = {1,3,5,7,9}.
C = {4,5,6}, as the problem states
a) The union of sets is a set containing all elements that are in at least one of the sets. So the union of A and C is a set that contains all elements that are in at least one of A or C.
So AUC = {2,4,6,8,10}.
b) The intersection of two sets consists of all elements that in both sets. So, the intersection of B and C is the set that contains all elements that are in both B and C.
There are no elements that are in both B and C, so the intersection is an empty set
BnC = {}
c) Same explanation as b), there are no elements that are in both A and B, so another empty set.
AnB = {}
d) The difference of sets B and C consists of all elements that are in B and not in C. We already have in b) that BnC = {}, so:
B-C = B = {1,3,5,7,9}
Answer:
35x867= 30,345
52x438= 22,776
1979/13= around 152
7488/9= 832
543.5+2.3= 545.8
25.1+1.9= 27
33.2-5.3=27.9
554.3-15.3=539
4.01<4.11
23.23<23.32
11.4=11.40
53.11>53.011
