URGENT ! what is the common difference of the arithmetic series 14+12+10+8
Answers
Explanation:
An arithmetic sequence has a common difference, meaning you use addition or subtraction to get from term to term, and each term in the sequence is an equal distance apart.
A geometric sequence has a common ratio, meaning that you use multiplication or division to get from term to term.
If you look at this sequence:
14-2 = 12
12-2 = 10
10-2 = 8
8 -2 = 4
etc.
Because you are subtracting 2 each time, 2 is the common difference, and the sequence is arithmetic.
Consider the square with vertices at (3, 3), (−3, 3), (−3, −3) and (3, −3). How many points with integer coordinates lie strictly in the interior of this square?
Answers
Answer:
The number points with that lie strictly in the interior of the square are 25 points
Step-by-step explanation:
The vertices of the square are; , (3, 3), (-3, 3), (-3, -3) and (3, -3)
From the attached diagram of the square created with Microsoft Word, where one box is equal to one unit, the number of points with integer coordinates that lie strictly in the interior of the square are given by the number of intersecting grid lines
The number of points on the interior of the square = 25 points
The points includes;
(-2, 2), (-1, 2), (0, 2), (1, 2), (2, 2)
(-2, 1), (-1, 1), (0, 1), (1, 1), (2, 1)
(-2, 0), (-1, 0), (0, 0), (1, 0), (2, 0)
(-2, -1), (-1, -1), (0, -1), (1, -1), (2, -1)
(-2, -2), (-1, -2), (0, -2), (1, -2), (2, -2).

The value of expression 2a ^ 2 + 2b ^ 2 - ab for a-2, b-lis (a) 2 (b) 8 (c) 6 (d) 10
Answers
Answer:
[tex]2a^2 + 2b^2 - ab[/tex] [tex]= 8[/tex]
Step-by-step explanation:
Given
[tex]2a^2 + 2b^2 - ab[/tex]
Required
Evaluate when [tex]a=2\ and\ b=1[/tex]
To do this, we simply substitute 2 for a and 1 for b in [tex]2a^2 + 2b^2 - ab[/tex]
[tex]2(2)^2 + 2(1)^2 - 2 * 1[/tex]
[tex]2*4 + 2*1 - 2 * 1[/tex]
[tex]8 + 2 - 2[/tex]
[tex]8[/tex]
Hence:
[tex]2a^2 + 2b^2 - ab[/tex] [tex]= 8[/tex]
when [tex]a=2\ and\ b=1[/tex]

Cam is 3 years older than Lara, If there combined age is 63, determine their ages by solving simultaneous elmination.
Answers
Answer:
30 and 33 years
Step-by-step explanation:
Let Lara be x years
Cam =x+3
x+x+3=63
2x+3=63
2x=63-3
2x=60
x=60/2
x=30
Lara=30years and Cam =30+3+33years
Answer:
Lara 30 years, Cam 33 years
Step-by-step explanation:
denote x being the age of Lara
denote y being the age of Cam
Cam is 3 years older than Lara, so
y = x + 3
their combined age is 63 so
x + y = 63.
solving can be done by plugging in y = x+3, then
x + (x+3) = 63, which gives x = 30.
So Lara is 30 years.
Cam is 3 years older, so Cam is 33 years

MATH FINAL TOMORROW! PLEASE HELP!
I have no idea what piecewise functions are or how to solve them! Please explain how, thank you!
I'm willing to give up a lot of points to understand this, so please help me.
Answers
Answer:
A piece wise function is pretty easy
Think of it like as a lot of functions with inequalities.
So lets say for example
Your Going to a skate park that counts time
Up to 6 minutes costs $50
Over 6 and up to 15 minutes costs $80
Over 15 minutes costs $80 plus $5 per minute above 15 minutes
The function would look something like
H(t)={ $50 If T is less then Or equal to 6
$80 If T is greater then 6 AND T less then or equal to 15
$80+$5(T-15) If T is greater then 15 }
Just simplify the worded problems into inequalities
And then a question would be something like, you visit for 13 minutes, how much would you pay?
It‘d be $80 becuase the chart says, if T (13) is greater then 6 And less then or equal to 15, its be 80 dollars.
