Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference =
Common ratio =
The common difference applies to the other given numbers for example :
this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
Answer:
I see this
"Which relation is a function?
A {(-3,4),(-3,8),(6,8)}
B {(6,4),(-3,8),(6,8)}
C {(-3,4),(3,-8),(3,8)}
D {(-3,4),(3,5),(-3,8)}"
So the answer is none of these.
Please make sure you have the correct problem.
Step-by-step explanation:
A set of points is a function if you have all your x's are different. That is, all the x's must be distinct. There can be no value of x that appears more than once.
If you look at choice A, this is not a function because the first two points share the same x, which is -3.
Choice B is not a function because the first and last point share the same x, which is 6.
Choice C is not a function because the last two points share the same x, which is 3.
Choice D is not a function because the first and last choice share the same x, which is -3.
None of your choices show a function.
If you don't have that choice you might want to verify you written the problem correctly.
This is what I see:
"Which relation is a function?
A {(-3,4),(-3,8),(6,8)}
B {(6,4),(-3,8),(6,8)}
C {(-3,4),(3,-8),(3,8)}
D {(-3,4),(3,5),(-3,8)}"
The measure of the three angles are 56, 28 , 192 degree
<h3>What is a Triangle ?</h3>
A triangle is a polygon with three sides , three vertices an three angles.
It is given to make system of equations
Let the measure of the first , second and third angle be x, y and z
the sum of the measures of the first two angles is 12 less than the measure of the third angle.
x +y = z -12 ----1
the measure of the first angle is twice as big as the measure of the second angle.
x = 2y
Now equation 1 will be
z - 3y = 12
x +y+z = 180
2y +y +z = 180
3y +z = 180 ----2
z - 3y = 12------3
On solving the system of equation 1, 2
2z = 192
z= 96 degree
3y = 180-96
y = 28
x = 56
Therefore the measure of the three angles area 56, 28 , 192 degree.

You simply need to devide the distance by the speed to get the time, so: 600÷50= 12hrs
This is only if you drive the same speed rhe whole way and do not stop. If you stopped you need to add the delay to the time.
For example: if you delayed 20 min altogether you need to add 12:00+00:20= 12:20.
